Changing Ocean Chemistry :: Ocean Carbon & Biogeochemistry

Marine organisms require many elements for their survival such as carbon, oxygen, hydrogen, nutrients (e.g., nitrogen, phosphorus, silicon), and trace elements (e.g., iron, cobalt, cadmium, zinc). The OCB community is interested in the biogeochemical cycling of these elements in the ocean and how they are changing through time, particularly in response to climate variability and change. Rising atmospheric CO₂ levels are not only increasing global temperatures but as the ocean absorbs more of this CO₂, it is changing the chemistry of the seawater, a process called ocean acidification (OA). In addition to OA, the oceans are undergoing many other concurrent changes in chemistry, including deoxygenation and pollution from nutrients and other sources. OCB researchers seek to understand the key drivers and dynamics of ocean chemistry changes and their implications for marine life and human communities.
