The phytoplankton that mediate CO2 upta ke in the marine biosphere are tremendously diverse\, non-homogeneously di stributed and oftentimes physiologically ill-characterized.

Exchanges across the AS F transport CDW toward marine-terminating glaciers\, and export Antarctic Bottom Water (AABW) to the abyssal ocean. Recent studies indicate that thi s exchange may be modulated by mesoscale eddies\, which facilitate cross-s lope exchanges via stirring along isopycnals and eddy bolus transports. In this seminar I will discuss physical controls over the rates of cross-slo pe water mass exchange\, and examine the dynamical balances governing cros s-slope eddy transfer. \n\nI will first present a recently-developed eddy- resolving process model of the Antarctic continental shelf and slope. The model enforces realistic offshore ocean stratification over idealized shel f/slope bathymetry\, in order to provide a realistic representation of the water masses in a configuration that can be analyzed cleanly. The model f orcing includes a westward wind stress over the continental slope and buoy ancy loss on the continental shelf\, consistent with prevailing Antarctic easterly winds and brine rejection in coastal polynyas.\n\nI will use this model to explore the sources of eddy kinetic energy (EKE) over the contin ental slope\, and its resulting impact on the cross-slope transport of mas s and tracers. I will show that the upper-ocean dynamics resemble the Anta rctic Circumpolar Current\, with wind-driven northward shoaling of the pyc nocline resisted by baroclinic conversion of potential energy to EKE. By c ontrast\, close to the ocean bed (at the CDW/AABW interface) potential ene rgy is removed by both the wind-driven mean overturning and the generation of baroclinic eddies\, and is instead sourced from the buoyancy loss on t he continental shelf. This EKE source turns out to be sensitive to variati ons in the model surface forcing and bathymetry. Consequently\, relatively small changes in the forcing and geometry can produce a substantial rearr angement of the water mass pathways and volume transports across the conti nental slope. These findings suggest that shoreward eddy transport of CDW should be localized to a few favorable locations around the Antarctic shel f break\, and that future changes in the easterly wind strength or coastal polynya productivity could significantly alter the shoreward heat transpo rt and the properties of the outflowing AABW.

Perturbatio n experiments are conducted in which a pattern of anomalous heat flux corr esponding to the NAO is added to the model ocean\; in companion experiment s no such flux is added. Differences between the experiments illustrate ho w the model ocean and climate system respond to the NAO. A positive phase of the NAO tends to strengthen the AMOC by extracting heat from the subpol ar gyre\, thereby increasing deepwater formation\, horizontal density grad ients\, and the AMOC. The flux forcings have the spatial structure of the observed NAO\, but the amplitude of the forcing varies sinusoidally in tim e with distinct periods varying from 2 to 200 years. The response of the A MOC to NAO variations is small at short time scales\, but increases up to the dominant time scale of internal AMOC variability (20-30 years for the models used). The amplitude of the response of the AMOC\, and associated o ceanic heat transport\, is approximately constant as the timescale of the forcing is increased further. In contrast\, the response of other properti es\, such as hemispheric surface air temperature or Arctic sea ice\, conti nues to increase as the time scale of the forcing becomes progressively lo nger. The larger response of temperature and sea ice at progressively long er time scales is associated with an increased impact of radiative feedbac k processes. The impact of the NAO-induced AMOC variations extends to the Southern Ocean as well\, inducing variations in surface and interior ocean properties. This relationship results in some skill in decadal prediction of aspects of the Southern Ocean.

Perturbation experiments are conducted in which a pattern of anomalous heat flux corresponding to the NAO is add ed to the model ocean\; in companion experiments no such flux is added. Di fferences between the experiments illustrate how the model ocean and clima te system respond to the NAO. A positive phase of the NAO tends to strengt hen the AMOC by extracting heat from the subpolar gyre\, thereby increasin g deepwater formation\, horizontal density gradients\, and the AMOC. The f lux forcings have the spatial structure of the observed NAO\, but the ampl itude of the forcing varies sinusoidally in time with distinct periods var ying from 2 to 200 years. The response of the AMOC to NAO variations is sm all at short time scales\, but increases up to the dominant time scale of internal AMOC variability (20-30 years for the models used). The amplitude of the response of the AMOC\, and associated oceanic heat transport\, is approximately constant as the timescale of the forcing is increased furthe r. In contrast\, the response of other properties\, such as hemispheric su rface air temperature or Arctic sea ice\, continues to increase as the tim e scale of the forcing becomes progressively longer. The larger response o f temperature and sea ice at progressively longer time scales is associate d with an increased impact of radiative feedback processes. The impact of the NAO-induced AMOC variations extends to the Southern Ocean as well\, in ducing variations in surface and interior ocean properties. This relations hip results in some skill in decadal prediction of aspects of the Southern Ocean.

In many flows the intrinsic symmetries create invariant surfaces that act as barriers to cha otic advection and mixing. Thus\, a key to efficient mixing is to add to t he original (symmetric) flow a certain kind of perturbation that destroys those symmetries. In the present talk we discuss a quantitative long-time theory of mixing due to the presence of resonances in 3-D near-integrable Stokes flows. The resonance phenomena\, such as scattering on resonance\, capture into resonance\, and separatrix crossings\, involving different co mponents of the original flow and the perturbation may destroy the invaria nt surfaces\, paving a way to the large-scale mixing in a big fraction of the fluid flow. We explain the extend and the rate of mixing in terms of t he evolution of the adiabatic invariants of the system. We show that when the leading phenomenon is scattering on resonances or separatrix crossings \, the resulting mixing can be described in terms of a single 1-D diffusio n-type equation\, with parameters of the diffusion equation defined by the averaged statistics of a single passage through resonance or separatrix.

The experimental setup is motivated by the continental shelf of the West Anta rctica Peninsula. Numerical experiments are performed to study how the wid th and slope of an idealized continental shelf topography affect the chara cteristics of the flow. The main focus is on the regime where the shelf br eak width is slightly greater than the eddy scale. In this regime\, a stro ng baroclinic jet develops on the shelf break due to the locally stabilizi ng effect of the topographic slope. The velocity of this jet is set at fi rst order by the gradient of the background barotropic geostrophic contour s\, which is dominated by the slope of the topography. At statistical equi librium\, an aperiodic cycle is observed. Initially\, over a long stable p eriod\, an upper-layer jet develops over the shelf break. Once the vertica l shear reaches the critical condition for baroclinic instability\, the je t becomes unstable and drifts away from the shelf break. The cross-shelf m ixing is intrinsically linked with the jet drifting\, as most of the merid ional flux occurs during this instability period. Investigation of the zon al momentum budget reveals that a strong Reynolds stress divergence invers ion across the jet is associated with a drifting event\, accelerating one flank of the jet and decelerating the other. The hypothesis that jet drift ing may be due to one flank of the jet being more baroclinically unstable than the other\, is tested using topographic profiles with variable curvat ures.

To overcome aspects of this limitation\, we develop ed the FlowCytobot series of automated submersible flow cytometers capable of rapid\, unattended analysis of individual plankton cells for long peri ods of time. FlowCytobot and Imaging FlowCytobot use a combination of lase r-based scattering and fluorescence measurements and video imaging of indi vidual particles to enumerate and characterize cells ranging from picocyan obacteria to chaining-forming diatoms. When combined with automated proces sing and image classification\, these observations make it possible to cha racterize taxonomic composition of plankton communities with unprecedented temporal resolution\, ranging from hours to years. Multi-year time series from FlowCytobot and Imaging FlowCytobot are now being used to study bloo m dynamics and community structure in US coastal waters.

FlowCytobot an d Imaging FlowCytobot use a combination of laser-based scattering and fluo rescence measurements and video imaging of individual particles to enumera te and characterize cells ranging from picocyanobacteria to chaining-formi ng diatoms. When combined with automated processing and image classificati on\, these observations make it possible to characterize taxonomic composi tion of plankton communities with unprecedented temporal resolution\, rang ing from hours to years. Multi-year time series from FlowCytobot and Imagi ng FlowCytobot are now being used to study bloom dynamics and community st ructure in US coastal waters.

Whether this role is important\, however\, depends on the strength of this mixing\ , which remains poorly qualified on global scale. To address this question \, a passive tracer was released upstream of the Drake Passage in 2009 as a part of the Diapycnal and Isopycnal Mixing Experiment in the Southern Oc ean (DIMES). While the mixing rates inferred from vertical dispersion of t he tracer are large and imply a key role played by mixing in setting the M OC\, those based on localized microstructure measurements seem to suggest otherwise. In this work we use a high resolution numerical model of the Dr ake Passage region\, sampled in the DIMES experiment and tuned to its obse rvations\, to explain that the difference between the two estimates arise from the large values of mixing encountered by the tracer when it flows cl ose to the bottom topography. We conclude that enhanced bottom mixing\, in combination with large lateral stirring and mixing by mesoscale eddies\, is sufficiently strong to play an important role in setting the Southern O cean branch of the MOC below 2 km.

In this work we use a high resolution numerical model of the Drake Passage region\, sample d in the DIMES experiment and tuned to its observations\, to explain that the difference between the two estimates arise from the large values of mi xing encountered by the tracer when it flows close to the bottom topograph y. We conclude that enhanced bottom mixing\, in combination with large lat eral stirring and mixing by mesoscale eddies\, is sufficiently strong to p lay an important role in setting the Southern Ocean branch of the MOC belo w 2 km.

An increase in the efficiency of the biological pump has been hypothesized to contribute to higher ocean carbo n storage during glacial periods. Here we use a model of the ocean's bioge ochemical cycles that includes both carbon (13C) and nitrogen (15N) isotop es but no sediment interactions. We present results from one present day s imulation and six simulations of the Last Glacial Maximum (LGM\, ~20 ka be fore the present). The LGM simulations are idealized sensitivity experimen ts that explore effects of changes in maximum phytoplankton growth rates ( mmax). Increasing mmax in the model leads to a more efficient biological p ump\, more carbon storage\, and lower d13CDIC and oxygen concentrations. T he resulting increase of denitrification stimulates additional nitrogen fi xation and increases the spatial variance of d15NNO3\, while decreasing th e ocean’s fixed nitrogen inventory. Increased nitrogen fixation lowers sur face d15NNO3 in most of the tropics. In the model’s Southern Ocean modest increases in mmax result in higher d15NNO3 due to enhanced local nutrient utilization\, consistent with reconstructions\, but larger mmax cause decl ining values there owing to the poleward transport of low tropical d15NNO3 . Comparison to reconstructions from LGM sediments indicates that models w ith moderately increased mmax (by 16 - 33 %) fit both isotope data best\, whereas large increases are inconsistent with nitrogen isotopes although t hey still fit the carbon isotopes reasonably well. The best fitting models reproduce major features of the glacial d13CDIC\, d15N\, and oxygen recon structions\, while simulating reduced carbon storage\, compared with the p re-industrial ocean\, due to lower preformed carbon concentrations. We con clude that the biological pump was more efficient during the LGM. However\ , sediment interactions and whole ocean alkalinity changes may be required to increase ocean carbon storage. Our analysis illustrates interactions b etween the carbon and nitrogen cycles as well as the complementary constra ints provided by their isotopes.

Our analysis illustrates interactions between the carbon and nitro gen cycles as well as the complementary constraints provided by their isot opes.\n END:VEVENT BEGIN:VEVENT UID:48ns06qmk86uukgfrei1om9fb4@google.com DTSTAMP:20180502T144619Z CATEGORIES;LANGUAGE=en-US:WHOI Seminar | Biological Oceanography CONTACT: DESCRIPTION:The influence of sea ice and hydrography on phytoplankton bloom s in the rapidly changing Chukchi Sea (Arctic Ocean)\n\nMs. Kate E.

Those shed by western bound ary currents must then interact with shelf-slope topography at the western boundary.\n\nThis simple picture is complicated by the presence of other eddies and mean flows\, but satellite observations show that many western boundary continental shelves are affected by mesoscale eddies translating near the shelfbreak. In this SST image\, a Gulf Stream Warm Core Ring (ant icyclone) transports cold fresh shelf water offshore across the Mid-Atlant ic Bight shelfbreak. Using idealized numerical simulations\, I address thr ee questions:\n\n1. Does the eddy always get to the shelfbreak\, or can sl oping topography stop an eddy from crossing it?\n2. What is the magnitude of offshore transport driven by these eddies?\n3. What is the effect of th e eddy on the shelf's flow field?

This study investigates the generation of internal waves by decaying eddies in the North Atlantic western boundar y. The eddy presence and decay are measured from the altimetric surface re lative vorticity associated with an array of full-depth current meters ext ending ~100 km offshore at 26.5N. In addition\, internal waves are analyse d over a topographic rise from 2-year high-frequency measurements of an Ac oustic Doppler Current Profiler (ADCP)\, which is located 13 km offshore i n 600 m deep water. Despite an apparent polarity independence of the eddy decay observed from altimetric data\, the flow in the deepest 100 m is enh anced for anticyclones (25.2 cm/s) compared with cyclones (-4.7 cm/s). Acc ordingly\, the internal wave field is sensitive to this polarity-dependent deep velocity. This is apparent from the eddy-modulated enhanced dissipat ion rate\, which is obtained from a finescale parameterization and exceeds 10^-9 W/kg for near-bottom flows greater than 8 cm/s. The present study u nderlines the importance of oceanic western boundaries for removing the en ergy of low-mode westward-propagating eddies to higher-mode internal waves .

In particular\, O2 concentration and isotopic composition are tracers of gross and net pro ductivity. A persistent challenge in quantifying biological productivity f rom O2 measurements is the need to accurately parameterize the physical pr ocesses that also alter O2 concentration and isotopic composition (e.g.\, bubble-mediated gas exchange\, diffusive gas exchange\, and mixing). Measu rements of multiple inert gases\, such as the noble gases\, are used to de velop parameterizations for these physical processes.

Several two-layer th eories are extended to include upstream shear\, showing that solutions onl y exist for a limited range of upstream shear values. More realistic two-d imensional numerical simulations are guided by the two-layer theory predic tions\, and the results are used to evaluate the theories. The simulations also show the qualitative types of hydraulic transitions that occur\, inc luding undular bores\, fully turbulent jumps\, and conjugate state-like so lutions. Numerical simulations are also used to investigate the mixing\, a nd a few 3D numerical simulations are found to be consistent with the 2D r esults.\n\nWhen the upstream shear is increased and the basic two-layer th eories no longer exhibit solutions\, entrainment is required. Furthermore\ , the downstream structure of the flow has an important effect on the jump properties. These factors are investigated by modifying a two-layer theor y to allow entrainment and account for the downstream vertical velocity st ructure. The resulting theory indicates that entrainment and jump structu re become important factors that influence the jump height. However\, the results are very sensitive to how the downstream vertical profiles of velo city and density are incorporated into the layered model\, highlighting th e limitations of the two-layer approximation when the shear is large.\n\nW hile these two layer theories provide insight into the types of jumps that can occur and the mixing that they cause\, jumps such as those that occur in Knight Inlet are significantly influenced by factors such as topograph y\, tidal forcing\, and three-dimensional effects.

Biological availability of dissolved inorganic forms o f nitrogen is one of the most critical factors that constrains productivit y and biogeochemical cycling in ocean ecosystems. The nitrogen cycle is be ing dramatically affected by anthropogenic activities leading to known and undoubtedly as yet unknown impacts on the oceans. Marine microorganisms a 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 another. The species of marine microorganisms in the environment are still poorly known\, because many of the important species have been difficult to obtain in laboratory culture.

Biologi cal availability of dissolved inorganic forms of nitrogen is one of the mo st critical factors that constrains productivity and biogeochemical cyclin g in ocean ecosystems. The nitrogen cycle is being dramatically affected b y anthropogenic activities leading to known and undoubtedly as yet unknown impacts on the oceans. Marine microorganisms are key components of ocean ecosystems\, and are important in food webs\, as well as cycling elements\ , such as nitrogen\, from one chemical form to another. The species of mar ine microorganisms in the environment are still poorly known\, because man y of the important species have been difficult to obtain in laboratory cul ture.

For N2O\, I will show how stratospheric and tropospheric i sotope observations reveal a ‘smoking gun’ for increases in agricultural e missions (similar to the Suess Effect for 14CO2) and how N2O isotope measu rements can be used to distinguish between the influence of the stratosphe ric sink and oceanic and biospheric sources\, demonstrating that isotope m easurements can help in the attribution and quantification of surface sour ces in general (e.g.\, Ref. 2).\n1.

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.

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.

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.

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 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.

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.

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.

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 tropical meteorology and climate\, with a specialty in hurricane physics. His interests also include cumulus convection\, the role of clouds\, wate r vapor\, and upper-ocean mixing in regulation of climate\, and advanced m ethods 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 (1978) both from MIT. After completing his doctorate\ , he joined the faculty of the Atmospheric Sciences department of the Univ ersity of California at Los Angeles where he remained for three years\, wi th a brief hiatus filming tornadoes in Oklahoma and Texas.\n\nIn 1981 he j oined the faculty of the Department of Meteorology at MIT and was promoted to Full Professor in 1987 in what had since becomes the Department of Ear th\, Atmospheric and Planetary Sciences (EAPS). In 1989 he assumed directo rship of EAPS Center for Meteorology and Physical Oceanography\, a post he held until 1997. Subsequently he chaired the EAPS Program in Atmospheres\ , Oceans\, and Climate from 2009 to 2012. He is co-founder of the MIT Lore nz Center\, a climate think tank which fosters creative approaches to lear ning how climate works.\n\nProfessor Emanuel is the author or co-author of over 200 peer-reviewed scientific papers\, and three books\, including Di vine Wind: The History and Science of Hurricanes\, published by Oxford Uni versity Press\, and What We Know about Climate Change\, published by the M IT Press.

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. \n\nProfessor Emanuel is the author or co-author of over 200 peer-reviewed scientific papers\, and three books\, including Divine Wind: The History and Science of Hurricanes\, published by Oxford University Press\, and Wha t We Know about Climate Change\, published by the MIT Press.
