Abstract
Changing climate, shifting oceanographic conditions, and loss of seasonal sea ice have sparked significant concern for cascading biological consequences that can impact the overall structure and functioning of the Arctic ecosystem. The Ecosystems and Fisheries Oceanography (EcoFOCI) Program at the Alaska Fisheries Science Center has been conducting process research and long-term monitoring in the High Arctic for over 25 years using repeat, ship-based sampling, oceanographic mooring arrays, advanced tech platforms, and a suite of modeling approaches to understand climate impacts on high Arctic ecosystems. The suite of physical and biological data made available from these efforts provide historical context and a platform from which the emergent, rapid changes that are occurring in the arctic may be evaluated. Comparisons with historical measurements reveal large-scale changes in ice, ocean heating, transport and flow, species composition (phytoplankton, zooplankton, fishes, invertebrates), species distribution, seasonal phenology, and food web dynamics. This improved understanding of changes to whole ecosystem dynamics is then applied to fisheries and protected species resource management in support of the blue economy (e.g., energy, transport, tourism), and the sustainable use of ocean resources.
Bio
Dr. Janet Duffy-Anderson is the Program Manager for the NOAA/Alaska Fisheries Science Center's Recruitment Processes Program and co-lead for the Ecosystems and Fisheries Oceanography Coordinated Investigations (EcoFOCI) Program. Janet earned a BS from Lafayette College, a PhD from the University of Delaware, and she conducted postdoctoral work at Rutgers University and the University of Washington. She works at the US National Marine Fisheries Service/Alaska Fisheries Science Center linking fish early life history ecology to recruitment dynamics and ecosystem functioning in Alaska. She has a deep interest in the changing arctic ecosystem, and has worked to understand the mechanisms by which shifts in climate and oceanography influence fish distribution, trophic dynamics, population variability, and fishery outcomes. Janet uses this mechanistic understanding to develop indicators that can be used in stock assessments, forecasting, and Ecosystem Based Fishery Management decision making.
