Phytoplankton bloom near Alaska’s Pribilof Islands on September 22, 2014. The Pribilofs are surrounded by nutrient-rich waters in the Bering Sea. The milky green and light blue shading of the water indicates the presence of vast populations of microscopic phytoplankton—mostly coccolithophores, which have chalky calcite scales. Such phytoplankton form the foundation of a tremendously productive habitat for fish and birds. Caption by Kasha Patel and Mike Carlowicz.

Satellite chorophyll in the Indian Ocean (source: NASA Aqua MODIS). Eddies and filaments promotes the growth of phytoplankton during the winter monsoon by supplying nutrients and relieving light limitation (Resplandy et al., 2009).
Professor Laure Resplandy is a biogeochemical oceanographer. Her research goals are to understand how climate and ocean physics influence marine biogeochemistry and ecosystems and how these changes can in turn impact the Earth climate. Prof. Resplandy's approach is to design and develop numerical models (from ocean regions to global climate system) and statistical tools to interpret in-situ and satellite observations.

While storing carbon dioxide, the coastal ocean also releases methane and nitrous oxide. New research shows that understanding the impact of coastal oceans on climate requires more research into these fluxes and how they counteract each other.
