ESSAS 2011 OSM
Comparative Studies of Climate Effects on Polar and Sub-Polar Ecosystems:
Progress in Observation and Prediction
May 22-26, 2011, Seattle, WA, USA

Scope

The sub-arctic seas are among the regions that support the most important fisheries of the Northern Hemisphere and are regions anticipated to experience some of the most rapid changes in climate from global warming. The sub-arctic seas differ considerably in their latitude, and the amounts, sources, physical properties and biological constituents of advected water. In contrast, their fisheries are dominated by a few species of gadid fish, particularly species of cod and pollock. There is considerable concern that the combined effects of climate change and fisheries removals may shift these marine ecosystems into alternative stable states, which may have a lower yield of species valuable to people. Additionally, it is becoming increasing evident that the connections between the Arctic and the Sub-Arctic are important to both systems.

Comparison of the forcing mechanisms among the sub-arctic seas has been useful for learning more about these ecosystems, and the responses of their biological components, including commercially exploited fish stocks, to variation in physical and anthropomorphic forcing mechanisms. In response to interest in these ocean regions by the international community, ESSAS, with support of its international partners, IMBER, PICES and ICES, is holding a 2nd Open Science Meeting to facilitate interdisciplinary comparative studies of these important marine ecosystems and their present and future responses to climate variability. The symposium is open to all.

Comparative Studies of Climate Effects on Polar and Subpolar Ocean Ecosystems: Progress in Observation and Prediction
Guest Editors: K. Drinkwater, G. Hunt, Jr., O. Astthorsson, and E. Head

This Special Issue presents results from the ESSAS 2011 Open Science Meeting (OSM) on Comparative Studies of Climate Effects on Polar and Subpolar Ocean Ecosystems: Progress in Observation and Prediction held in Seattle, Washington, during May 2011. It contains 20 papers from the OSM along with an introduction to both the volume and the meeting. This meeting provided an opportunity to showcase the progress made within ESSAS and to identify remaining knowledge gaps and future research needs. The issue was dedicated in memory of Bernard Megrey who passed away unexpectedly on October 1, 2010. Dr. Megrey was strongly involved in ESSAS, particularly with the modeling of marine ecosystems. Papers in this issue cover a wide variety of topics, including ecosystem components from physics to marine mammals to humans. The volume is organized geographically, stretching from the Sea of Okhotsk in the Pacific, through into the Arctic and the Atlantic, and ending in the Barents Sea. In addition, one paper deals with the Antarctic. The OSM and the papers in this issue have provided new results and methods that expand our knowledge of the sub-Arctic seas.

Theme Section on Effects of climate and predation on subarctic crustacean populations
Editors: E. G. Dawe, F. Mueter and O. Palsson

This Theme Section includes 9 papers and reviews the ecological role of large marine decapods, presents selected case studies, and features comparative analyses of the dynamics of fish and crustacean populations and their interactions across several subarctic ecosystems. Collectively, the studies described here highlight the role of climate and predation in regulating fish and crustacean populations in these systems. The Theme Section has resulted from activities of ESSAS Working Group 4 on “Climate Effects at Upper Trophic Levels” presented at the topic session on “Interactions between gadoids and crustaceans: the roles of climate, predation and fisheries” and the workshop “Comparative analyses of gadid and crustacean dynamics across subarctic ecosystems” during the second ESSAS Open Science Meeting (OSM) in Seattle in May 2011.

Combining Modeling and Observations to Better Understand Marine Ecosystem Dynamics
Guest Editors: E. Curchitser, K. Rose, S. Ito, M. Peck and M. Kishi

This ESSAS-PICES special issue of Progress in Oceanography is dedicated to Dr. Bernard (Bern) Megrey, who was lost from the scientific community and his family far too early. Bern achieved many scientific accomplishments during his career in fisheries and oceanography and served ESSAS and PICES in many different roles, sometimes simultaneously. Bern is the only recipient of both of the major PICES awards–the PICES Ocean Monitoring Service Award (POMA) and the Wooster Award that recognizes individuals for significant scientific contributions to North Pacific marine science. The sixteen papers in this issue display some of the breadth of models in use for understanding the mechanisms linking environmental forcing to biological responses in ocean systems–it is a collection that Bern would be proud of.

Comparative studies have been one of the leading aspects of the ESSAS program. In this session results from comparative studies of entire ecosystems or of significant ecosystem components (zooplankton, fish, seabirds) will be presented. All papers should compare aspects of two or more systems. These can be among different polar or sub-polar seas or between sub-polar seas and other types of ecosystems, e.g. temperate, tropical, etc. Methods papers, as well as results from comparative studies, will be considered. Papers are sought on the similarities and differences in ecosystem structure and function and the processes that lead to these differences.

This session will highlight different approaches to modeling the impacts of climate variability on high latitude marine ecosystems and their ability to support sustainable ecosystem services. Papers on different types of models will be accepted including mass-balance (ECOPATH) models, size-based models, rule-of-thumb approaches, minimalist models, individual based models (IBMs) and end-to-end models. Special emphasis will be placed on models that examine trophic interactions as well as models that link biogeochemical processes with higher trophic level production. Papers on methods for estimating uncertainties in model predictions are also encouraged.

This session will focus on the sources of macro- and micro-nutrients in the sub-Arctic seas. How does the importance of the various pathways to primary production vary with season, and how do they affect the fate of the production? How do these differ between the Atlantic and Pacific oceans? How are these processes influenced by the presence of sea ice? Additionally, this session will include papers that discuss the responses of high latitude regions to either future climate or increasing acidification, or their combined response. Of particular interest are physical, chemical or biological thresholds or tipping points that will lead to large-scale changes in an ecosystem.

Polar and sub-polar marine systems are expected to be strongly impacted by anticipated climate change, and by anticipated economic development relating to fishing, tourism and, hydrocarbon exploration. Human socioeconomic systems in these regions year-round or seasonally are finely tuned to their present environments, with few alternative livelihood opportunities, and are also expected to be severely affected by these changes. This session will explore the potential for anticipating socio-economic conditions in coupled polar and sub-polar marine social-ecological systems. It seeks to identify the key policy issues and what policies are needed as these regions experience climate-driven environmental changes and economic development, with the focus on marine-related issues. Policy needs will include requirements for monitoring and observing of the full coupled social-ecological systems. A comparative approach among the different communities and countries of these regions will enable separation of general from regional and local understanding and policy issues. Such an approach could include the roles of seasonal migrants into these regions for marine-related activities. The session specifically seeks papers that address anticipating marine socio-economic aspects of climate change and economic development, anticipated policy needs related to these issues, and the understanding and information needs (e.g. monitoring) required to forecast responses and to formulate policies. Comparative studies at a variety of spatial scales, as well as studies that examine interactions and feedback mechanisms between humans and the environment, are particularly welcome. Publication of a collection of these presentations in a relevant primary journal will be discussed.

In this session we seek papers that document and investigate the processes that lead to shifts between demersal fish, especially gadoids such as cod and pollock, and crustaceans, such as shrimp and crabs. What role does gadoid predation play on the dynamics of shrimp and crabs? How does this compare to the influence of climate regimes or the effects of industrialized fishing? How does the spatial overlap between gadoids and crustaceans change seasonally and annually? Papers that address these questions either within a single ecosystem or compare different sub-Arctic regions are sought.

This workshop will review life history information and habitat associations to assess the risk of immigration and settlement of new biological populations in the Arctic and surrounding shelf seas in response to the retreat of sea ice. Criteria necessary to establish new species in the Arctic Ocean and surrounding areas will be developed and compared to expected conditions based on climate scenarios. Ways for cooperation in information sharing between groups charged with managing the Arctic will be explored and the results of the workshop will be reported to both PICES and ICES scientists working on these issues.

This workshop will build on the work of the Arctic-Subarctic Ocean Fluxes (ASOF) community that has focused on quantifying the fluxes around the Arctic and the successful IPY session on Arctic-Subarctic connections: Ecosystems and biodiversity at the Oslo IPY Conference in June of 2010. It will bring together several disperse groups that are studying these fluxes and their biophysical effects, including: ESSAS that has concentrated on the Subarctic and the effects on the marine biota, especially fish; those working on the benthic-pelagic coupling and the biogeochemistry in the Barents and the Greenland shelves; those looking at the interaction between the Chukchi Sea and the western Bering Sea; scientists who during the IPY studied the effects of the Bering Sea on the Western Arctic; and other interested scientists. The object is to identify the gaps in our knowledge and to highlight what research can be carried out over the next few years to fill some of these gaps in our understanding of the effects of the interactions between the Arctic and Sub-Arctic and to coordinate the research on these issues. Areas of interest include physical, biogeochemical, and food web studies.

This workshop will bring together researchers interested in understanding how climate and life history patterns of zooplankton interact to produce the observed distributions and abundances of key species found throughout the boreal Sub-Arctic and Arctic seas. The Workshop will build on work funded through the GLOBEC Pan-Regional Synthesis project, which is exploring how species pairs of copepods in the genus Calanus co-exist in the Atlantic and Pacific basins. That work is a combination of modeling efforts and data analysis, and combines both abundance and distribution data with vital rate data on reproduction, feeding, and development. This workshop will facilitate expansion of that work beyond a single genus. We seek enhanced collaboration within the community to further the understanding of how zooplankton life histories are affected by climate change. Of special interest will be the influence of ice cover and the prediction of the effects of reduced ice cover under global warming. Participation of researchers studying climate affects on zooplankton prey and predators is also encouraged.

This half-day workshop aims to summarize and synthesize the main findings to date of comparative analyses regarding the effects of climate and predator-prey interactions on gadid and crustacean stocks across subarctic ecosystems. The focus will be on studies conducted under the auspices of ESSAS Working Group 4, but the workshop is open to anyone conducting comparative analyses on fish and crustacean stocks in subarctic seas. As a secondary goal, we will discuss future directions for comparative studies of fish and crustacean resources across subarctic systems and the future of Working Group 4.

This workshop will focus on how to best integrate ongoing and new research on marine birds and mammals into long-term PICES and ESSAS programs and objectives; the overarching goal is to produce a strategic vision and plan for activities of the PICES MBMAP over the next 5 years. Specific workshop objectives include (1) producing an outline of potential new goals reflecting climate change impacts on marine birds and mammals in the northern hemisphere, (2) design and implementation of sub-groups to work on specific areas of interest including (i) models of climate impact (e.g., NEMURO.BIRD), (ii) conservation of threatened and endangered species, and (iii) communication, and (3) initial writing of strategic plan documents. The workshop will include some oral presentations, but the emphasis will be on discussions leading to planning documents.
