Recent decline of northern shrimp stocks in the Northwest Atlantic – Coincidence, multiple causes or response to synchronous changes in the environment?
Featured Research: After a period of record high catches, stock size of almost all Northwest Atlantic populations of northern shrimp (Pandalus borealis) has declined. This has been accompanied by a warmer ocean climate and, in some areas, by an increase of major predator abundance and raised concerns in the coastal states about the fishing possibilities on this valuable resource in the near future.

Ecosystem structure in the Iceland Sea and recent changes to the capelin (Mallotus villosus) population
Featured research: The objective of the Iceland Sea Ecosystem Project was to analyze principal ecosystem patterns, including the life history of capelin. Ten surveys were conducted for this purpose between 2006 and 2008, and hydrographic data from 1970 to 2011 were analyzed

Comparing ecosystems in the Northern Hemisphere
ESSAS Featured Research: For many years ESSAS has supported a productive collaboration between the Norway’s Institute of Marine Research, the National Oceanic and Atmospheric Administration (NOAA Fisheries) in the U.S., and the Department of Fisheries and Oceans (DFO) in Canada. Understanding the drivers of productivity in marine ecosystems continues to be a globally important issue.

Variability in the North Atlantic Oscillation and Hydrography in the Northwest Atlantic:
Will the Events of 1997-1998 be repeated in 2011-2012? Canadian scientists from the Department of Fisheries and Oceans (DFO) at the Bedford Institute of Oceanography have been making physical, chemical and biological oceanographic observations annually at stations on a line across the Labrador Sea since 1994.

The Continuous Plankton Recorder (CPR) Survey in the NW Atlantic
ESSAS Featured Research: Continuous Plankton Recorders (CPRs) have been towed along routes between Iceland and Newfoundland (the Z route) and between Newfoundland and the NE coast of the United States (the E route) since the early 1960s. The data are analysed each year as a component of the Canadian Atlantic Zone Monitoring Programme.

ESSAS Poster Session on Arctic-Subarctic Interactions – At the 2012 Ocean Sciences Meeting
The Arctic and the Subarctic are intrinsically linked, not only through exchange of water but also in the fluxes and movement of flora and fauna between the two regions. Both regions are experiencing profound changes under present warming and are predicted to be even more highly impacted under future global change.
