Andreas Andersson is an Associate Professor of Oceanography in Scripps’ Geoscience Research Division. 

Andersson’s general research interest deals with global environmental change owing to both natural and anthropogenic processes, and the subsequent effects on the function, role, and cycling of carbon in marine environments. His current research is mainly concerned with ocean acidification in coral reefs and in near-shore coastal environments.  The aim of his current research attempts to address the relative importance and control of seawater CO2 chemistry and environmental parameters (e.g., light, temperature, nutrients, flow-regime) on reef biogeochemical processes and the interactions between physics, chemistry, and biology. He utilize’s chemical measurements of seawater at different spatial and temporal scales to “take the pulse” of a given reef system in order to monitor its biogeochemical function and performance. This is complemented with controlled experiments in aquaria and mesocosms as well as numerical model simulations. Andersson also studies CaCO3 dissolution, and especially the susceptibility and rates of dissolution of Mg-calcite mineral phases to changing seawater CO2 chemistry.

Andersson was born and grew up in Sweden, but moved to Hawaii to attend college when he was old enough to make his own decisions. He holds a B.S. in marine biology from Hawaii Pacific University (he was valedictorian of the class of 2001), and a M.S. and a Ph.D. in chemical oceanography from the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa. Following completion of his Ph.D. in 2006, he accepted an appointment as post-doctoral fellow at the Bermuda Institute of Ocean Sciences (BIOS) and later as Assistant Research Scientist in 2008. After more than 13 years of subtropical island life in Hawaii and Bermuda, Andersson moved to San Diego and Scripps Institution of Oceanography in the summer of 2011.

Andersson is a member of the U.S. Ocean Carbon & Biogeochemistry (OCB) subcommitee on ocean acidification. He has worked and advised several NGOs on ocean acidification issues including The Nature Conservancy  and  Earthjustice representing the Pacific Small Island Developing States (PSIDS).
