Dramatic Changes in Bering Sea Ecosystem Noted by NOAA
Many rarely observed conditions occurred in the Bering Sea during the summers of 1997 and 1998, including extensive die-offs of seabirds, rare algal blooms, unanticipated low salmon runs, warmer than usual ocean temperatures, and altered ocean currents and atmospheric conditions.
These changes prompted scientists from NOAA, the federal agency that protects and predicts the nation's marine resources and atmospheric environment, to convene an international workshop in Seattle, Wash.
'People whose livelihood depends on the Bering Sea need to know if these are fleeting anomalies or persistent large-scale changes, ' said James Balsiger, head of the National Oceanic and Atmospheric Administration's Alaska Fisheries Science Center.
The eastern Bering Sea provides almost half of the fish and shellfish caught in the United States.
'We wanted to bring together scientists, environmentalists, administrators, resource managers, native Alaskans, representatives of the fishing industry, and others at this crucial time, ' said Eddie Bernard, director of NOAA's Pacific Marine Environmental Laboratory in Seattle.
'During the workshop, more than 75 participants shared information, proposed reasons for these environmental changes, and suggested future research needs.

Bering Sea Ecosystems Issue Approximately forty percent of the total U.S.
commercial fisheries landings by weight comes from the Bering Sea.
Pollock abundance in the southeast Bering Sea has declined significantly since the mid- l980's with population levels fluctuating widely since the 1960's.
Map of Spawning Grounds of Deep Sea Wallye Pollock Past studies have indicated that pollock larvae are a key component in the food web, and that the deep basin of the Bering Sea may not be able to maintain the abundance of larval fish needed to sustain the fishery and the feeding of predators, such as marine mammals and seabirds.
Fisheries scientists and managers require better information to determine the integrated role of fishing pressure and changing environmental factors on Bering Sea resources, or to understand key ecosystem linkages.
A management system tuned to the ecosystem “as a whole” is needed to manage resource levels, resolve utilization conflicts, and sustain this valuable ecosystem.
CSCOR ’s research is responding to this need by increasing our understanding of the underlying physical and biological processes that regulate this ecosystem.
