DESCRIPTION:Marine ecosystems and ocean acidification. \n\nThe ocean holds
50 times more carbon than the atmosphere. Because of its large buffer capa
city\, the ocean will eventually absorb 60 to 85% of the carbon dioxide em
itted to the atmosphere on a time scale of 1000 years or longer. However t
he uptake of carbon dioxide by the ocean has the side effect of acidifying
the water\, with negative consequences for marine ecosystems and unclear
implications for the functioning of the marine carbon cycle. This lecture
will detail the linkages between marine ecosystem processes (from bacteria
to jellyfish) and the carbon cycle. It will show how ecosystem processes
can be understood through their biogeochemical functionality\, and explain
the knowns and unknowns of the impacts of ocean acidification. The lectur
e will end with a discussion of how changes in marine ecosystems could hav
e knock on effects on climate regulation.

DESCRIPTION:Title: The response of tropical low clouds to climate change\n
\nAbstract: Uncertainties in how tropical low clouds respond to climate ch
ange continue to dominate climate projections. They have resisted reductio
n for decades. Because of a convergence of what is feasible computationall
y on large scales (general circulation models) and small scales (large-edd
y simulations)\, and because of the wealth of detailed observations that a
re now available\, substantial progress on the low-cloud problem is now wi
thin reach. In this talk\, I will describe recent progress in: \n\n(a) con
straining the low-cloud response to climate change observationally\, \n(b)
understanding how the large-scale energy balance controls the low-cloud r
esponse\, and (c) simulating the low-cloud response with large-eddy simula
tions that are driven in a way that respects the large-scale energy balanc

DESCRIPTION:Marine microbial diversity and nitrogen: does species diversity
matter?\n\nMarine microorganisms are responsible for half of the biologic
al productivity on Earth\, but are reliant on supplies of major nutrients

y and biogeochemical cycling in ocean ecosystems. The nitrogen cycle is be

re key components of ocean ecosystems\, and are important in food webs\, a
s well as cycling elements\, such as nitrogen\, from one chemical form to

to obtain in laboratory culture. Molecular biology and genomics approaches
have identified new species\, and also have shown that known taxa are com

have different ecological niches. Is this diversity important for the nitr

raw on the rich source of nitrogen in the atmosphere (78% of the atmospher
e)\; these organisms\, called nitrogen-fixing microorganisms (diazotrophs)
are very important components of oceanic ecosystems\, are very difficult
to study\, and are likely to be sensitive to changes in climate and nitrog

y within the past few decades\, using these cultivation-independent approa
ches\, a novel unicellular symbiosis between 2 single-celled microorganism
s was discovered that now appears to be one of the most abundant nitrogen-
fixing microorganisms\, and plays a key role in global oceanic nitrogen cy
cling. I will discuss how technological advances are needed to determine h

DESCRIPTION:“Microbe-mediated trace gas fluxes—linking ecosystem genomics t
o atmospheric composition”\n\nMicroorganisms play a significant role in dr
iving biogeochemical cycles. These cycles include biosphere-atmosphere exc
hange of trace gases (e.g.\, CO2\, CH4) that influence atmospheric composi
tion and climate. Soils teem with microbial life that produce and consume
trace gases. Understanding microbe-environment interactions is critical fo
r predicting the response of terrestrial ecosystems to changes in land use
and climate.\n\nIn my research\, I quantify the microbial imprint on atmo
spheric composition and climate using an interdisciplinary set of methods\
, ranging from genomics to micrometeorology. My work focuses on resolving
the genomic underpinnings of microbe-mediated biogeochemical transformatio
ns in soils that drive significant atmospheric fluxes (e.g.\, H2\, COS\, 1
8O-CO2\, CO2\, CH4). The goal of my work is to determine when and how proj
ections of biogeochemical transformations are improved by better represent
ation of underlying biological drivers.

\\n\\n“Microbe-mediate
d trace gas fluxes—linking ecosystem genomics to atmospheric composition”
\n\nMicroorganisms play a significant role in driving biogeochemical cycle
s. These cycles include biosphere-atmosphere exchange of trace gases (e.g.
\, CO2\, CH4) that influence atmospheric composition and climate. Soils te
em with microbial life that produce and consume trace gases. Understanding
microbe-environment interactions is critical for predicting the response
of terrestrial ecosystems to changes in land use and climate.\n\nIn my res
earch\, I quantify the microbial imprint on atmospheric composition and cl
imate using an interdisciplinary set of methods\, ranging from genomics to
micrometeorology. My work focuses on resolving the genomic underpinnings
of microbe-mediated biogeochemical transformations in soils that drive sig
nificant atmospheric fluxes (e.g.\, H2\, COS\, 18O-CO2\, CO2\, CH4). The g
oal of my work is to determine when and how projections of biogeochemical
transformations are improved by better representation of underlying biolog
ical drivers.

DESCRIPTION:Scaling properties of Arctic sea ice deformation in high-resolu
tion viscous-plastic sea ice models\n\nMany climate models use a rheology
of the viscous-plastic type to simulate sea ice dynamics. With this rheolo
gy\, large scale velocity and thickness fields can be realistically simula
ted\, but the representation of small scale deformation rates and Linear K
inematic Features (LKF) is thought to be inadequate. However\, at high res
olution (< 5 km) the rheology starts to produce lines of localised deforma
tion rates. In this study we use results from a 1-km Pan-Arctic model to i
nvestigate the influence of these deformation features on the scaling prop
erties of sea ice deformation. For evaluation the EGPS satellite data set
of small-scale sea ice kinematics for the Central Arctic (successor of RGP
S) is used.\nThe modelled sea ice deformation shows multi-fractal spatial
scaling and\, in this sense\, agrees with the satellite data. In addition\
, the temporal coupling of the spatial scaling is reproduced as well. Furt
hermore\, we examine the regional and seasonal variations of spatial scali
ng properties and its dependence on the ice condition\, i.e. sea ice conce
ntration and thickness\, which are in agreement with previous RGPS studies
.

DESCRIPTION:Title: A metabolic constraint on the biogeography of marine spe
cies\n\nAbstract: Oxygen played a key role in the evolution of marine ecos
ystems. However\, oxygen has not generally been considered a major constr
aint on the contemporary biogeography of species outside regions of except
ionally low O2. I will present a combination of physiological\, climate\,
and species distribution data\, to argue that the limits of several diver
se species ranges are governed by the ratio of oxygen supply and demand\,
even in the well-oxygenated Atlantic Ocean. These limits correspond to an
energetic requirement for organismal activity of about 2-5 times that at
rest\, a ratio that is shared by most terrestrial species. This metaboli
c constraint is rapidly tightened in the presence of climate warming due t
o the combination of warmer water and less O2. I will use Earth System Mo
dels to investigate and compare the loss of aerobically viable habitat in
two periods of interest – the climate change projected for the 21st centur
y and the end-Permian mass extinction.

DESCRIPTION:A Tale of Two Tracers: Radiocarbon and nitrous oxide isotopolog
ues\nand their sources and sinks from recent observations\n\nBoth CO2 and
N2O are long-lived atmospheric trace gases that\, coincidentally\, become
enriched in rare\, heavy isotopes in the stratosphere followed by return t
o the troposphere\, where the stratospheric enrichments are diluted by emi
ssions of isotopically light CO2 (e.g.\, fossil fuel combustion) and N2O (
e.g.\, microbial production). In this talk\, I will focus on measurements
of 14CO2 and of the oxygen and intramolecular nitrogen isotopic compositio
n of N2O in the stratosphere and troposphere. For CO2\, I will show how we
use new observations in the stratosphere (e.g.\, Ref 1) to estimate empir
ically the global annual mean production rate of 14C by cosmic rays and th
e net 14C flux from the stratosphere to the troposphere useful for carbon
cycle studies\, as well as to monitor stratospheric residence times to see
if they are changing in response to a predicted acceleration of the Brewe
r-Dobson Circulation as the climate warms. For N2O\, I will show how strat
ospheric and tropospheric isotope observations reveal a ‘smoking gun’ for
increases in agricultural emissions (similar to the Suess Effect for 14CO2
) and how N2O isotope measurements can be used to distinguish between the
influence of the stratospheric sink and oceanic and biospheric sources\, d
emonstrating that isotope measurements can help in the attribution and qua

DESCRIPTION:Deciphering deep ocean circulation changes between the present
and the last glacial\n\nThe paleoclimate record indicates that the deep oc
ean circulation and water masses have undergone major rearrangements betwe
en glacial and interglacial climates\, which have likely played an importa
nt role in the observed atmospheric carbon dioxide swings by affecting the
partitioning of carbon between the atmosphere and ocean. The mechanisms b
y which the deep ocean circulation changed\, however\, are still unclear a
nd represent a major challenge to our understanding of past and future cli
mates.\n\nWe address this question using a hierarchy of numerical models o
f varying complexity\, ranging from a highly idealized ocean-only model to
coupled climate simulations from the Paleoclimate Modelling Intercomparis
on Project (PMIP). The results suggest that various inferred differences i
n the deep ocean circulation and stratification between glacial and interg
lacial climates can be attributed to increased Antarctic sea-ice formation
in a colder world. Colder temperatures lead to thicker ice\, which is exp
orted by winds. The associated increased freshwater export leads to saltie
r and denser Antarctic Bottom Water\, consistent with high abyssal salinit
ies inferred for the Last Glacial Maximum (LGM). The enhanced deep ocean s
tratification moreover results in a weakening and shoaling of the inter-he
mispheric overturning circulation\, again consistent with proxy evidence f
or the LGM. \n\nThe results also highlight the importance to distinguish b
etween the equilibrium and transient response of the ocean circulation to
climatic changes. The adjustment of the deep ocean circulation is found to
be highly non-monotonic\, with the response on centennial time-scales dif
fering qualitatively from the equilibrium results. This distinction is rar
ely observable in complex coupled climate models\, which cannot be integra
ted for sufficiently long times.

DESCRIPTION:Title: Inventing Atmospheric Science: Gordian Knots and the Que
st for Prevision\n \nAbstract: Atmospheric researchers have long attempted
to untie the Gordian Knot of meteorology—that intractable and intertwined
tangle of observational imprecision\, theoretical uncertainties\, and non
-linear influences—that\, if unraveled\, would provide perfect prevision o
f the weather for ten days\, of seasonal conditions for next year\, and of
climatic conditions for a decade\, a century\, a millennium\, or longer.
This presentation\, based on Inventing Atmospheric Science (The M.I.T. Pre
ss\, 2016)\, examines the work of three interconnected generations of scie
ntists and the influence of three families of transformative technologies
in the first six decades of the twentieth century\, from the dawn of appli
ed fluid dynamics to the emergence\, by 1960\, of the interdisciplinary at
mospheric sciences.\n\nAbout the speaker: Jim Fleming is the Charles A. Da
na Professor of Science\, Technology\, and Society at Colby College\, Main
e. He earned a B.S. in astronomy from Pennsylvania State University\, an M
.S. in atmospheric science from Colorado State University\,\nand a Ph.D.
in history from Princeton University. He has written extensively on the hi
story of weather\, climate\, technology\, and the environment including so
cial\, cultural\, and intellectual aspects. His books include Meteorology
in America (Johns Hopkins\, 1990)\, Historical Perspectives on Climate Cha

\\n\\nTitle: Inventing
Atmospheric Science: Gordian Knots and the Quest for Prevision\n \nAbstra
ct: Atmospheric researchers have long attempted to untie the Gordian Knot
of meteorology—that intractable and intertwined tangle of observational im
precision\, theoretical uncertainties\, and non-linear influences—that\, i
f unraveled\, would provide perfect prevision of the weather for ten days\
, of seasonal conditions for next year\, and of climatic conditions for a
decade\, a century\, a millennium\, or longer. This presentation\, based o
n Inventing Atmospheric Science (The M.I.T. Press\, 2016)\, examines the w
ork of three interconnected generations of scientists and the influence of
three families of transformative technologies in the first six decades of
the twentieth century\, from the dawn of applied fluid dynamics to the em
ergence\, by 1960\, of the interdisciplinary atmospheric sciences.\n\nAbou
t the speaker: Jim Fleming is the Charles A. Dana Professor of Science\, T
echnology\, and Society at Colby College\, Maine. He earned a B.S. in astr
onomy from Pennsylvania State University\, an M.S. in atmospheric science
from Colorado State University\,\nand a Ph.D. in history from Princeton U
niversity. He has written extensively on the history of weather\, climate\
, technology\, and the environment including social\, cultural\, and intel
lectual aspects. His books include Meteorology in America (Johns Hopkins\,
1990)\, Historical Perspectives on Climate Change (Oxford\, 1998)\, The C
allendar Effect (AMS\, 2007)\, Fixing the Sky (Columbia\, 2010)\, and Inve
nting Atmospheric Science (MIT\, 2016). He is series editor of Palgrave St
udies in the History of Science and Technology\, a research associate of t
he Smithsonian Institution\, a fellow of the American Association for the
Advancement of Science\, and a fellow of the American Meteorological Socie
ty. \n\nJim is a resident of China\, Maine (not Mainland China!) He enjoys
fishing\, good jazz\, good BBQ\, seeing students flourish\, and building
the community of historians of science and technology. 'Everything is unpr
ecedented if you don't study history.'\n\nProfile: http://www.colby.edu/di

DESCRIPTION:The vertical structure of ocean eddies\n\nSince we began observ
ing the ocean surface with satellites\, \nit's been of interest to underst
and how the surface fields reflect motion\nat depth. A series of recent mo
deling studies suggest the vertical structure \nis fairly well-captured by
a single mode\, intensified near the surface and\ndecaying to zero with d
epth. A study of 69 globally-distributed current \nmeters supports this\,
in many locations outside of the tropics. The reason\nfor the dominance of
a surface is explored theoretically\, using a simple\ntwo layer model. Th
e latter predicts a wavenumber frequency spectra \nwhich resembles that in
the ocean\, except at small scales. The latter are \nshown to be more lik
ely to transfer energy to large scales\, leaving the\n(non-dispersive) lar
ge scale waves in tact. A similar conclusion was made \npreviously from id
ealized numerical experiments.

DESCRIPTION:Stability and Internal Flow Variability of Ice Sheets\n\nIce st
reams are regions of fast-flowing ice embedded within ice sheets that acco
unt for the majority of mass transport from ice sheet interiors to the oce
an. Variability of ice stream flow on centennial to millennial time scales
plays an important role in the present mass balance of the West Antarctic
Ice Sheet. In this talk\, I show how a simple model of subglacial meltwat
er production coupled to ice flow explains the underlying physical mechani
sm for millennial-scale\, unforced ice stream variability and predicts the
transition to steady ice stream flow. The model equally well reproduces m
odern ice stream variability in the Siple Coast region of West Antarctica
and Heinrich events\, periods of increased ice discharge from the Laurenti
de Ice Sheet during the last glacial period. In a more realistic\, purpose
-built model\, the same mechanism produces variability and rapid migration
s of the ice stream grounding line. These migrations are always associated
with mass imbalance near the grounding line\, but not necessarily in the
ice stream at large\, which is important to consider when interpreting mod
ern observations of grounding line variability. Under certain conditions\,
this ice stream variability may cause the grounding line to slow down for
hundreds to thousands of years even as it retreats onto a reverse bed slo
pe\, before readvancing. Such behavior runs counter to the conventional th
eories predicting the instability of ice sheets on reverse bed slopes. Det
ermining if such behavior occurs in real ice sheets is important when eval
uating the likelihood of irreversible ice sheet collapse and rapid sea lev
el rise in the future.

DESCRIPTION:Lateral mixing by mesoscale eddies is widely recognized as a cr
ucial mechanism for the global ocean circulation and the associated heat/s
alt/tracer transports. The Salinity in the Upper Ocean Processes Study (SP
URS) confirmed the importance of eddy mixing for the surface salinity fiel
ds even in the center of the subtropical gyre of the North Atlantic. We fo
cus on the global salinity maxima due to their role as indicators for glob
al changes in the hydrological cycle as well as providing the source water
masses for the shallow overturning circulation.\nWe introduce a novel app
roach to estimate the contribution of eddy mixing to the global sea surfac
e salinity maxima. Using a global 2D tracer experiments in a 1/10 degree M
ITgcm setup driven by observed surface velocities\, we analyze the effect
of eddy mixing using a water mass framework\, thus focussing on the diffus
ive flux across surface isohalines. This enables us to diagnose temporal v
ariability on seasonal to inter annual time scales\, revealing regional di
fferences in the mechanism causing temporal variability.Sensitivity experi
ments with various salinity backgrounds reveal robust inter annual variabi
lity caused by changes in the surface velocity fields potentially forced b

DESCRIPTION:Chasing Water: Lagrangian tracking of tracers\, plastic and pla

around\, it caries heat and nutrients\, as well as larger objects like pl
anktonic organisms and litter around the globe.\n\nThe most natural way to
study the pathways of water and the connections between ocean basins is u
sing particle trajectories. The trajectories can come from either computin
g of virtual floats in high-resolution ocean models\, or from the paths of
free-flowing observational drifters (surface buoys or Argo floats) in the
real ocean.\n\nIn this seminar\, I'll give an overview of some recent wor

raphy\, marine ecology\, palaeoclimatology and marine plastic pollution. C
entral to each of these studies is the question on how connected the diffe

DESCRIPTION:Title: Monsoon circulations and tropical heterogeneous chlorine
chemistry in the stratosphere\n\nAbstract: This seminar presents novel fi
ndings that expand the range of latitudes over which heterogeneous chemist
ry operates in the stratosphere. It has long been thought that heterogen
eous chlorine chemistry would only be important in the Antarctic and Arcti
c. Our new work shows that tropical heterogeneous chemistry is also imp
ortant. Transport processes associated with the summer monsoons bring i
ncreased abundances of hydrochloric acid into contact with liquid sulfate
aerosols in the cold tropical lowermost stratosphere\, leading to heteroge
neous chemical activation of chlorine species. The calculations indicate
that the spatial and seasonal distributions of chlorine monoxide and chlo
rine nitrate near the monsoon regions of the northern hemisphere tropical
and subtropical lowermost stratosphere could provide indicators of heterog
eneous chlorine processing. In the model\, these processes impact the lo
cal ozone budget and decrease ozoneabundances\, implying a chemical contri
bution to longer-term northern tropical ozone profile changes at 16-19 km.

DESCRIPTION:Title: A few new perspectives on humanity and Earth’s climate\n
\nAbstract:\n\nWhen fossil fuel energy was discovered\, the timing and int
ensity of the resulting climate impacts depended on what the natural CO2 c
oncentration in the atmosphere was at that time\, which could have been an
ything. The radiative forcing scales as the ratio of the fossil fuel CO2
in the atmosphere to the background\, natural CO2 concentration. Assuming
continued exponential growth in the fossil carbon in the atmosphere\, alt
ering the background concentration has the effect of dialing the radiative
forcing and climate response back and forth in time. If the natural conc
entration had been a factor of two or more lower\, the climate impacts of
fossil fuel CO2 release would have occurred about 50 or more years sooner\
, making it much more challenging for the developing human society to scie
ntifically understand the phenomenon of anthropogenic climate change in ti
me to prevent it.\n\nNow that we understand the situation\, much of our de
cision-making progress involves money. The costs of cutting CO2 emissions
(mitigation) can be balanced against a construct called the Social Cost o
f Carbon\, which is formulated to represent future costs as their present-
day equivalents using discounting\, in order to compare fairly against the
immediate costs of mitigation. U.S. EPA valued the SCC at about $40 / to
n of CO2. I will show the derivation of a different but complementary num
ber\, the potential Ultimate Social Cost of Carbon to 5000 future human ge
nerations of the climate impacts from fossil CO2 release. Long term sea l
evel rise of 50 meters provides the clearest impact. I get about $40k / t
on CO2. The formulation treats humanity as any other component of the ter
restrial biosphere\, in an end-member case where we do not transcend biolo
gical limitations such as by soil and water availability. Costs are integ
rated through time based on the assumption that each generation of humanit
y values its world (whatever it may look like) equally to any other genera
tion\, in particular to our own.

DESCRIPTION:Warm-route versus cold-route interbasin exchange in the meridio
nal overturning circulation - Why is the Atlantic saltier than the Pacific
?\n\nThe interbasin exchange of the meridional overturning circulation (MO
C) is studied in an idealized domain with two basins connected by a circum
polar channel in the southernmost region. Gnanadesikan’s (1999) conceptual
model for the upper branch of the MOC is extended to include two basins o
f different widths connected by a re-entrant channel at the southern edge
and separated by two continents of different meridional extents. Its analy
sis illustrates the basic processes of interbasin flow exchange either thr
ough the connection at the southern latitude of the long continent (cold
route) or through the connection at the southern latitude of the short con
tinent (warm route). A cold-route exchange occurs when the short continent
is poleward of the latitude separating the sub-polar and sub-tropical gyr
e in the southern hemisphere\, otherwise there is warm-route exchange. The
predictions of the conceptual model are compared to primitive equation co
mputations in a domain with the same idealized geometry forced by wind-str
ess\, surface temperature relaxation and surface salinity flux. A visualiz
ation of the horizontal structure of the upper branch of the MOC illustrat
es the cold and warm routes of interbasin exchange flows. Diagnostics of t
he primitive equation computations show that the warm-route exchange flow
is responsible for a substantial salinification of the basin where sinking
occurs. This salinification is larger when the interbasin exchange is via
the warm route\, and it is more pronounced when the warm-route exchange f
lows from the wide to the narrow basin.

DESCRIPTION:Barotropic turbulence above topography: form stress and eddy sa
turation\n\nWind is an important driver of large-scale ocean currents\, im
parting momentum into the ocean at the sea surface. This force is almost e
ntirely balanced by topographic form stress (that is the correlation of bo
ttom pressure and topographic slope). The direct effect of bottom or skin
friction in turbulent boundary layers is almost negligible for the momentu
m balance. We use a one-layer barotropic model to study the effect of a ra
ndom monoscale bottom topography on beta-plane geostrophic turbulence. The
model forcing is a uniform steady wind stress that produces both a unifor
m large-scale flow and smaller-scale macroturbulence. The macroturbulence
is characterized by both standing and transient eddies and the large-scale
flow is retarded by a combination of bottom drag and domain-averaged topo
graphic form stress produced by the standing eddies. \n\nA main control pa
rameter is the ratio of beta to the root mean square gradient of the topog
raphic potential vorticity (PV). We derive asymptotic scaling laws for the
strength of the large-scale flow in the limiting cases of weak and strong
forcing. If beta is comparable to\, or larger than\, the topographic PV g
radient there is an “eddy saturation” regime in which the large-scale flow
is insensitive to large changes in the wind stress. We show that eddy sat
uration requires strong transient eddies that act effectively as PV diffus
ion. This diffusion does not decrease the strength of the standing eddies
but it does increase the topographic form stress by enhancing the correlat
ion between topographic slope and the standing eddy pressure field.

DESCRIPTION:Southern Ocean eddies: generation\, propagation and decay\n\nTh
e Southern Ocean has high concentrations of eddy kinetic energy\, but anal
ysis of altimeter data and an ocean state estimate show that the generatio
n of relatively large amplitude eddies is not a ubiquitous feature of the
Southern Ocean but rather a phenomenon that is constrained to isolated\, w
ell-defined regions. Five “hotspots” of high probability of eddy generatio
n are identified using altimeter data. These hotspots are located downstre
am of major topographic features\, with their boundaries closely following
f/H contours. Eddies generated in these locations do not propagate far bu
t decay within the boundaries of the generation area. The anisotropy of th
e dispersion of eddy tracks in geographical coordinates versus a rotated c
oordinates system aligned with f/H contours\, shows that eddies tend to fo
llow f/H contours rather than f. Maps of buoyancy and shear production ter
ms computed from a state estimation model show enhanced values of both con
version terms inside the hotspots\, with buoyancy production two orders of
magnitude larger than shear production. The mean potential density field
estimated from Argo floats shows that inside the hotspots isopycnal slopes
are steep\, indicating availability of potential energy and providing fur
ther evidence of the main generation mechanism. The hotspots identified in
this paper overlap with previously identified regions of standing meander
s. We hypothesize that hotspot locations can be explained by the combined
effect of topographic features\, standing meanders which enhanced baroclin
ic instability and availability of potential energy to generate eddies via
baroclinic instabilities.

ith f/H contours\, shows that eddies tend to follow f/H contours rather th
an f. Maps of buoyancy and shear production terms computed from a state es
timation model show enhanced values of both conversion terms inside the ho
tspots\, with buoyancy production two orders of magnitude larger than shea
r production. The mean potential density field estimated from Argo floats
shows that inside the hotspots isopycnal slopes are steep\, indicating ava
ilability of potential energy and providing further evidence of the main g
eneration mechanism. The hotspots identified in this paper overlap with pr
eviously identified regions of standing meanders. We hypothesize that hots
pot locations can be explained by the combined effect of topographic featu
res\, standing meanders which enhanced baroclinic instability and availabi
lity of potential energy to generate eddies via baroclinic instabilities.

DESCRIPTION:Title: Monsoon circulations and tropical heterogeneous chlorine
chemistry in the stratosphere\n\nAbstract: This seminar presents novel fi
ndings that expand the range of latitudes over which heterogeneous chemist
ry operates in the stratosphere. It has long been thought that heterogen
eous chlorine chemistry would only be important in the Antarctic and Arcti
c. Our new work shows that tropical heterogeneous chemistry is also imp
ortant. Transport processes associated with the summer monsoons bring i
ncreased abundances of hydrochloric acid into contact with liquid sulfate
aerosols in the cold tropical lowermost stratosphere\, leading to heteroge
neous chemical activation of chlorine species. The calculations indicate
that the spatial and seasonal distributions of chlorine monoxide and chlo
rine nitrate near the monsoon regions of the northern hemisphere tropical
and subtropical lowermost stratosphere could provide indicators of heterog
eneous chlorine processing. In the model\, these processes impact the lo
cal ozone budget and decrease ozone abundances\, implying a chemical contr
ibution to longer-term northern tropical ozone profile changes at 16-19 km

DESCRIPTION:High-resolution observations of internal wave induced turbulenc
e in the deep ocean \n\nAn overview is presented of high-resolution temper
ature observations above underwater topography in the deep\, generally sta
bly stratified ocean. The Eulerian mooring technique is used to monitor te
mperature variations by typically 100 sensors distributed over lines betwe
en 40 and 400 m long. The independent sensors sample at a rate of 1 Hz for
up to one year with a precision better than 0.1 mK. This precision and sa
mpling rate are sufficient to resolve the large\, energy containing turbul
ent eddies and all of the internal waves and their breaking above underwat
er topography. Such underwater wave breaking is the key mechanism for the
redistribution of nutrients and heat (to maintain the ocean stably stratif
ied)\, and the resuspension of sediment.\n\nUnder conditions of tight temp
erature-density relationship\, the temperature data are used to quantify t
urbulent overturns. These observations show two distinctive turbulence pro
cesses that are associated with different phases of a large-scale\, mainly
tidal\, internal gravity wave: i) highly nonlinear turbulent bores during
the upslope propagating phase\, and ii) Kelvin-Helmholtz billows\, at som
e distance above the slope\, during the downslope phase. While the former
may be associated in part with convective turbulent overturning following
Rayleigh-Taylor instabilities\, the latter are mainly related to shear-ind
uced instabilities. Under weaker stratified conditions\, away from boundar
ies\, free convective mixing appears more often\, but a clear inertial sub
range in temperature spectra is indicative of dominant shear-induced turbu
lence. With stratification\, turbulence is seen to increase in dissipation
rate and diffusivity all the way to the bottom\, which challenges the ide
a of a homogeneous bottom boundary layer. With a newly developed five-line
s mooring\, the transition from isotropy (full turbulence) to anisotropy (
stratified turbulence/internal waves) is revealed.

\\n\\nBiostratigraphy
and Glaciations in the Neoproterozoic: Updates from Re-Os geochronology\n
\nSedimentary strata from the Neoproterozoic Era (1000-541 Ma) host eviden
ce for widespread glaciations\, major fluctuations in geochemical proxy re
cords\, and numerous biological innovations associated with the diversific
ation of eukaryotes that culminated with the emergence of Metazoans. Under
standing the drivers and rates of change through this critical transition
has been limited by the lack of a robust chronology. Here I will present m
ultiple new Re-Os and U-Pb geochronology data from Neoproterozoic strata i
n an attempt to refine global correlation schemes and further constrain th
is critical interval of Earth history.

DESCRIPTION:Title: Can we finally balance the marine nitrogen budget?\n\nAb
stract: The marine fixed nitrogen budget is widely thought to be out of ba
lance\, losing enough bio-available nitrogen that the oceans would be devo
id of life within 3\,000 years. But is such a apocalyptic scenario realist
ic? Surely not. This talk will present nuances of the cycling of marine ni
trogen\, expanding specifically on the anaerobic metabolisms within the ox
ygen deficient “shadow” zones of the ocean. I’ll present a hypothesis for
attempting to balance the nitrogen budget calculation by incorporation of
a novel but potentially significant pathway: anaerobic nitrite oxidation.
This metabolism would further help resolve another long-standing debate am
ong the nitrogen community\, i.e.\, the respective roles of anammox and de
nitrification in regulating fixed nitrogen loss. In all\, a lunchtime full
of nitrogen is to be expected.

DESCRIPTION:The What\, When\, Where\, and Why of Supereruptions\n\nSupereru
ptions are gigantic volcanic eruptions (�450 km^3 of magma) the likes of w
hich we have never witnessed. Yet\, this does not mean that we will never
experience one. Such\nenormous eruptions have the potential to wreak havoc
on life\, infrastructure\, travel\, and the\nenvironment. Consequently\,
it is critical that we study past supereruptions to understand how\, when\
, where\, and why one might happen in the future. In addition\, supererupt
ion deposits are evidence that large volumes of magma existed in the crust
multiple times in Earth’s history\; thus\, studying these systems can inf
orm on the magmatic construction of Earth’s crust.\n\nIn this talk\, I wil
l address several outstanding and strongly debated questions regarding\nsu
pereruptive systems: Where in the crust do these magmas reside? What shape
do they take? How long do they persist in the crust before erupting? When
\, why\, and over what timescales does the eruptive process occur? How are
the giant volumes of crystal-poor high-silica rhyolite magma involved in
supereruptions generated? Answering these questions is important both for
practical reasons (e.g.\, hazards preparation and mitigation) and intellec
tual ones (e.g.\, understanding crustal processes). \n\nTo address these q
uestions\, I combine information from multiple scales and perspectives (fi
eld studies\, geochemistry\, textural relations of crystals in rocks and m
elt inclusions in crystals\, geochronology\, geobarometry\, phase-equilibr
ia modeling\, and diffusion modeling). Results from this work suggest that
we can make some broad generalizations about supereruptive systems\, but
these systems have notable variability as well (e.g.\, their shape in the
crust). This work also illustrates the power in using a multi-faceted\, mu

DESCRIPTION:A new perspective on an old problem: understanding the observed
variability of the South Asian monsoon\n\nRecent theoretical advances ind
icate that the South Asian monsoon (SAM) should be viewed as an energetica
lly-direct cross-equatorial Hadley circulation\, with the monsoonal precip
itation primarily occurring in its ascending branch\, rather than as a lar
ge land-sea breeze circulation. In this talk\, we explore the implications
of these emerging theories for the observed variability of the SAM on sea
sonal and longer time scales. We start by using the atmospheric moisture b
udget to introduce a novel objective index for the onset and retreat of th
e SAM\, which robustly captures the expected seasonal transitions in preci
pitation and winds and eliminates the need for arbitrarily selected thresh
olds. Using this index\, we show how the SAM onset and retreat are associa
ted with a coherent set of seasonal transitions in circulation\, jet strea
ms\, precipitation\, energetics\, and momentum balance throughout the SAM
sector. We also use the atmospheric moisture budget to define a new index
for the SAM strength on interannual time scales. We show that interannual
variability in SAM net precipitation is primarily caused by variations in
winds rather than variations in humidity\, and that strong monsoons are as
sociated with a northward expansion of the overturning circulation and a d
ecreased near-surface land-sea thermal contrast\, in disagreement with the
traditional view of the SAM as a sea-breeze circulation. We also find tel
econnections between SAM strength and temperatures\, winds\, and momentum
and energy transports in the southern hemisphere extra tropics\, which sug
gest new directions for future research to improve our understanding of th
e mechanisms involved in SAM variability.

DESCRIPTION:Title: Western Boundary Currents in a Changing Climate\n\nAbstr
act: Western boundary currents—such as the Agulhas Current in the Indian O
cean—carry heat poleward\, moderating Earth’s climate and fuelling the mid
-latitude storm tracks. They could exacerbate or mitigate warming and extr
eme weather events in the future\, depending on their response to anthropo
genic climate change. Climate models show an ongoing poleward expansion an
d intensification of the global wind systems\, most robustly in the Southe
rn Hemisphere\, and linear dynamical theory suggests that western boundary
currents will intensify and shift poleward as a result. Observational evi
dence of such changes comes from accelerated warming and air–sea heat flux
rates within all western boundary currents\, which are two or three times
faster than global mean rates. Here we show that\, despite these expectat
ions\, the Agulhas Current has not intensified since the early 1990s. Inst
ead\, we find that it has broadened as a result of more eddy activity. Rec
ent analyses of other western boundary currents—the Kuroshio and East Aust
ralia currents—hint at similar trends. These results indicate that intensi
fying winds may be increasing the eddy kinetic energy of boundary currents
\, rather than their mean flow. This could act to decrease poleward heat t
ransport while increasing cross-frontal exchange of heat (and nutrients an
d pollutants) between the coastal ocean and the deep ocean. Sustained in s
itu measurements are needed to properly understand the role of these curre
nt systems in a changing climate.

DESCRIPTION:Role of Seasonal Transitions and the Westerlies on the Rainfall
Climate of East Asia\n\nThe East Asian Summer Monsoon is unique amongst s
ummer monsoonal systems in in northward extent as well as in its complex s
easonality\, exhibiting dynamically distinct rainfall stages and abrupt tr
ansitions between them. Previous studies have alluded to the seasonally-va
rying downstream influence of the westerlies flowing around the Tibetan Pl
ateau as central to the rainfall seasonality. I propose a hypothesis that
the East Asian summer rainfall variability and change arise through modula
tion in the meridional position of the westerlies impinging on the Plateau
\, which in turn altered the timing and duration of its seasonal transitio

DESCRIPTION:Observations show that the upper ocean has been warming since t
he 1970s\, and it is usually attributed to global warming that is associat
ed with the increasing concentration of greenhouse gases in the atmosphere
. The global ocean is implicitly considered as a passive heat reservoir\,
and it is assumed that the ocean was in equilibrium with the atmosphere be
fore the anthropogenic global warming had occurred. However\, the global o
cean is a dynamically active heat exchanger involving processes of various
temporal and spatial scales and has a memory of thousands of years. Not o
nly the heat exchange between ocean and atmosphere but the vertical heat f
lux passing the lower face of the upper ocean contribute to the changes in
the observed upper ocean heat content. In this talk\, I will present the
mean and the bidecadal change of the ocean vertical heat flux as well as t
he related physical processes from a dynamically consistent and data-const
rained ocean state estimate - ECCO (Estimating the Circulation & Climate o
f the Ocean). Implications of the vertical redistribution of ocean heat on
the changes of the upper and deep ocean heat contents\, particularly the
recently much-debated global warming 'hiatus'\, will also be discussed.

DESCRIPTION:Speaker: Kerry A. Emanuel\, Cecil & Ida Green Professor of Atmo
spheric Science\, Co-Director of the Lorenz Center\nDate: Wednesday\, Sept
ember 20\, 4:00pm to 5:00pm\nLocation: MIT Campus\, 54-100\n\nSpecial Lect
ure: 'What Do Hurricanes Harvey and Irma Portend?'\n\nNatural disasters ar
e the result of the interaction of a natural phenomenon with human beings
and their built environments. Globally and in the U.S.\, large increases i
n coastal populations are causing corresponding increases in hurricane dam
age and these are now being compounded by rising sea levels and changing s
torm characteristics owing to anthropogenic climate change. In this talk\,
I will describe projections of changing hurricane activity over the rest
of this century and what such projections tell us about how the probabilit
ies of hurricanes like Harvey and Irma have already changed and are likely
to continue to do so.\n\nAbout the Speaker\n\nKerry Emanuel is a prominen
t meteorologist and climate scientist who specializes in moist convection
in the atmosphere\, and tropical cyclones. His research interests focus on

Kerry Emanuel: What
Do Hurricanes Harvey and Irma Portend?[/caption]\n\n
Speaker: Kerry A. Emanuel\, Cecil & Ida Green Professor of Atmospheric Science\
, Co-Director of the Lorenz Center\nDate: Wednesday\, Sep
tember 20\, 4:00pm to 5:00pm\nLocation: MIT Campus\, 54-1
00\n\nSpecial Lecture: 'What Do Hurricanes Harv
ey and Irma Portend?'\n\nNatural disasters are the result of
the interaction of a natural phenomenon with human beings and their built
environments. Globally and in the U.S.\, large increases in coastal popula
tions are causing corresponding increases in hurricane damage and these ar
e now being compounded by rising sea levels and changing storm characteris
tics owing to anthropogenic climate change. In this talk\, I will describe
projections of changing hurricane activity over the rest of this century
and what such projections tell us about how the probabilities of hurricane
s like Harvey and Irma have already changed and are likely to continue to
do so.\n\nAbout the Speaker\n\nKerry Emanuel is a prominent meteorologist and cl
imate scientist who specializes in moist convection in the atmosphere\, an
d tropical cyclones. His research interests focus on tropical meteorology
and climate\, with a specialty in hurricane physics. His interests also in
clude cumulus convection\, the role of clouds\, water vapor\, and upper-oc
ean mixing in regulation of climate\, and advanced methods of sampling the
atmosphere in aid of numerical weather prediction.\n\nEmanuel received an
S.B. degree in Earth and Planetary Sciences and a Ph.D. in Meteorology (1
978) both from MIT. After completing his doctorate\, he joined the faculty
of the Atmospheric Sciences department of the University of California at
Los Angeles where he remained for three years\, with a brief hiatus filmi
ng tornadoes in Oklahoma and Texas.\n\nIn 1981 he joined the faculty of th
e Department of Meteorology at MIT and was promoted to Full Professor in 1
987 in what had since becomes the Department of Earth\, Atmospheric and Pl
anetary Sciences (EAPS). In 1989 he assumed directorship of EAPS Center fo
r Meteorology and Physical Oceanography\, a post he held until 1997. Subse
quently he chaired the EAPS Program in Atmospheres\, Oceans\, and Climate
from 2009 to 2012. He is co-founder of the MIT Lorenz Center\, a climate t
hink tank which fosters creative approaches to learning how climate works.
