The Senate Commerce Committee sponsored a Congressional Staff Briefing on 24 June at the Capitol building in Washington DC, organized by Dr. Richard Merrick, entitled Closing the Data Gaps: Challenges in Stock Assessment Science. AFSC scientist Kerim Aydin attended and presented results of the Bering Sea Integrated Research Program on integrating climate effects (especially ice) into the stock assessment for walleye pollock.

BSIERP FEAST 6-Year Project Wrap-Up and Future Work

Delivery of the final report for the Forage Euphausiid Abundance in Space and Time (FEAST) model - part of the Bering Sea Integrated Ecosystem Research Project (BSIERP)- concluded a 6-year multi-disciplinary project which produced 12 peer-reviewed publications (several currently in review) and 31 presentations at international meetings. FEAST has been used to focus some of the fieldwork and started a collaborative framework between field researchers and modelers, a process that has now been implemented at the AFSC across several Divisions and teams as well as NOAA’s Pacific Marine Environmental Laboratory (PMEL). FEAST will also be a centerpiece of its strategy developing an Integrated Ecosystem Assessment (IEA) for the Alaska region. This effort, part of NOAA’s national IEA program, will not only include regular updates to FEAST but will also use the model as a focus for collaborative fieldwork from disciplines from physics through biology, economics, and social sciences. As IEAs focus on delivering management results, this will serve as a direct conduit for bringing process-oriented fieldwork into the management arena via management strategy analyses, ecosystem indicator development, and improved prediction capabilities both in the short and long term.

The Norway-United States Climate Change and Marine Ecosystems (NUCCME) Workshop

Kirstin Holsman (Joint Institute for the Study of the Atmosphere and Ocean, University of Washington/AFSC) and Mike Sigler (AFSC) attended the Norway-United States Climate Change and Marine Ecosystems (NUCCME) meeting in Norway  on 5-9 May. The international workshop is the third in a series of Marine Ecosystems of Norway and the United States (MENU) workshops and was aimed at comparative evaluation of climate effects on arctic and sub-arctic marine ecosystems. Meeting participants split into three working groups loosely centered around: 1) climate projections of primary and secondary productivity and species recruitment; 2) multi-species model projections of climate effects on fisheries; and 3) potential economic and societal consequences of climate change in the two regions. The first two objectives are those of NUCCME/ MENU III while the last fits within the CLIFFIMA-net objectives. Each working-group identified and began writing a subset of paper topics that will compose a special issue of Climate Change in 2015. In particular, AFSC researchers Holsman and Sigler are leads on two papers, respectively 1) “A Comparative Approach for Methods of Including Climate Features in Future Projections and Setting of Harvest Control Rules” and 2) “Projected Rcruitment of Bering, Barents, and Norwegian Sea Fish Species Under Climate Change Using ROMS/NPZ Predictions of Future Conditions.”

Arctic Ecosystem Integrated Survey PI Meeting

Kerim Aydin and Andy Whitehouse participated in the Arctic Ecosystem Integrated Survey (EIS) principal investigator’s meeting, 17-19 June in Juneau, Alaska. The goal of the Arctic EIS is to contribute to a comprehensive assessment of oceanography, lower trophic levels, and fish of the northeastern Bering Sea and eastern Chukchi Sea shelf. At this meeting, Kerim and Andy presented results of diet analyses of several fish species collected during various fisheries research surveys.
