Abstract:
Marine planktonic calcifiers such as coccolithophores, foramanifera, and pteropods play a fundamental role in the ocean carbon system, a role that may be modified substantially by rising atmospheric CO2 and climate change. The overall goal of this project is to better constrain the magnitude of ocean acidification and climate change impacts on marine inorganic carbon dynamics, ocean carbon storage and atmospheric CO2 levels over the next several decades to centuries. Our primary numerical tool will be the new Community Earth System Model, version 1 (CESM, v.1), a variant of the widely used Community Climate System Model (CCSM) that includes fully interactive marine ecosystem and global carbon modules. Satellite observations will be integral to the project in terms of both model parameterization development and model-data evaluation. The specific objectives are four fold:
1). Utilize historical satellite remote sensing (SeaWiFS; MODIS) and in situ data to characterize the biogeographic niche for marine calcifiers; i.e., the temperature, circulation and seawater chemistry "phase-space" for calcifiers;
2). Improve the existing CESM marine ecosystem module to incorporate more explicit ecological treatment of distinct biological calcifiers and modify biological calcification and carbonate dissolution rates so that they are sensitive to changing seawater chemistry;
3). Verify against satellite and in situ data the simulated fields of marine planktonic calcification including the spatial distributions and seasonal to decadal temporal variability;
4). Quantify the projected changes over the 21st century in the patterns and strength of marine biological calcification in a warmer, higher-CO2 world and the resulting feedbacks on ocean carbon storage.
