Ocean Chemistry
Biogeochemistry
Biogeochemistry studies the cycles of crucial elements, such as carbon and nitrogen, and their interactions with other substances and organisms as they move through Earth’s atmosphere, hydrosphere, biosphere, and lithosphere.
Ocean Acidification
Ocean acidification is a reduction in the pH of the ocean over an extended period of time, caused primarily by an increase of carbon dioxide from the atmosphere.
Oxygen Dead Zones
Dead zones occur when the water lacks oxygen. Like us, marine animals require oxygen to breathe, and when oxygen levels drop too low they can suffocate.
