The Global Viewport films focus on hydrothermal vents, which are like underwater hot springs located mainly along Earth’s plate boundaries at depths as deep as 5000 meters (3 miles) below the ocean surface. These vents spew iron and sulfur-rich minerals and super-heated water up to 760 degrees Fahrenheit. (Image by Beaulieu, et al, 2014)
