Marginal Ice Zone: Biogeochemical Sampling with Gliders

Abstract

The long-term goal is to understand how phytoplankton, the primary producers of the ocean and base of marine food webs, are responding to changing conditions in the Arctic Ocean. The high-level project goals are to use underwater profiling gliders to determine the distribution of phytoplankton, particulate organic carbon, and rates of production of organic carbon in the Arctic under the ice and in the marginal ice zone. The project specific goals are to develop biogeochemical and optical proxies for glider optics; to use the proxies to project biogeochemical and optical measurements from ship-board measurements to the larger spatial scales sampled by the gliders in open water, in the marginal ice zone, and under the ice; to use glider optical measurements to compute fields of rates of photosynthetic carbon fixation; and to build collaborations with Arctic scientists at KOPRI.
