Abstract:

Long times-series are required for scientists to tease out pattern and causation in the presence of substantial year-to-year variability. For the 10-year period beginning in 2022, we propose to continue multi-disciplinary oceanographic observations begun in fall 1997 in the Northern Gulf of Alaska. Cruises occur in early May, July, and mid-September to capture the typical spring bloom, summer conditions, and fall transition, respectively, along a 150-mile cross-shelf transect to the south of Seward, Alaska. The line is augmented by stations in the entrances and deep passages of Prince William Sound. We determine the physical-chemical structure, the distribution and abundance of phytoplankton, microzooplankton and mesozooplankton, and survey seabirds and marine mammals. These observations enable descriptions of the seasonal and inter-annual variations of this ecosystem. Our goal is to characterize and understand how different climatic conditions influence the biological conditions across these domains within each year, and what may be anticipated under future climate scenarios.
