Title: <\/strong>The Distributed Biological Observatory (DBO): A Change Detection Array in the Pacific Arctic Region (Phase 2)
\nPrincipal Investigator:<\/strong> Karen Frey
\nFunding Agency:<\/strong> National Science Foundation<\/p>\n

Within the Pacific Arctic region, the northern Bering and Chukchi Seas are among the most productive marine ecosystems. Recent shifts in seasonal sea-ice cover are having profound consequences for seasonal phytoplankton production as well as affecting intimately linked upper trophic level species, including those harvested locally for subsistence. Key uncertainties remain as to how the marine ecosystem will respond to seasonal shifts in the timing of spring sea-ice retreat and\/or delays in fall sea-ice formation. The internationally coordinated Distributed Biological Observatory network provides a change detection array that allows for consistent sampling and monitoring of productivity hotspots by all participants. The overarching goal of this continuing project is to use coordinated south-to-north observations as a \u201cspace for time\u201d strategy in which a suite of physical, biochemical, and biological measurements evaluate ecosystem change both seasonally and inter-annually over the spatially diverse latitudinal gradient. Working with collaborators from the University of Maryland, University of Washington, and Woods Hole Oceanographic Institute, specific questions for Phase 2 include:<\/p>\n
