The nature and extent of changing sea ice over the Bering Sea shelf and the timing of its retreat have a profound impact on the timing and nature of the spring phytoplankton bloom. However, there is little knowledge of community compositional variability of the phytoplankton blooms and how the zooplankton community may respond or be impacted by such changes.
The overarching goal of this study is to understand the response of phytoplankton and zooplankton communities to changing ice dynamics in the Bering Sea. This project (1) integrates ship measurements of phytoplankton species composition, their size structure and productivity to understand the potential consequences on zooplankton populations measured from moored acoustical observations, (2) integrates ship-based observations of size structure and photo-physiological properties of phytoplankton with optical measurements to refine satellite algorithms for the retrieval of phytoplankton size composition, chlorophyll concentration, and primary production and (3) utilizes in situ observations and satellite observations of ocean color and of sea-ice conditions to improve modeled physical, biogeochemical and ecosystem dynamics.
The project is organized around the following primary science questions:
