Phytoplankton bloom near Alaska’s Pribilof Islands
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.

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.

Research Interests:

Changes in ocean oxygenation.
Global change, ocean acidification and carbon cycle.
Influence of ocean physics on biological activity and biogeochemical fluxes.
Climate modeling, ocean small-scale (1 to 100 km) modeling.

While the ocean as a whole is losing oxygen due to warming, oxygen minimum zones (OMZs) are maintained by a delicate balance of biological and physical processes; it is unclear how each one of them is going to evolve in the future.

OCEAN PROVIDES A BUFFER AGAINST CLIMATE CHANGE

Professors Laure Resplandy and Daniel Sigman explain how the ocean absorbs heat and carbon dioxide, providing a buffer against climate change. Researchers are modeling the long-term impacts to marine ecosystems and climate.
