NOAA places a high priority on research in the Arctic. The North Pacific Ocean is warming and the thickness and extent of the Arctic ice is shrinking. Loss of sea ice is having a profound effect on the distribution, migration, energetics, and survival of commercially important fish species in the Bering Sea/Chukchi Sea. Scientists within the Ecosystem Monitoring and Assessment Program partnered with the University of Alaska Fairbanks, School of Fisheries and Ocean Sciences to provide a comprehensive assessment of the northeastern Bering Sea and Chukchi Sea (NEBS/CS) ecosystems including the physical environment, the primary and secondary producers that support Arctic marine food webs, and the numerous fish species utilizing the area. Research is planned to begin during 2012.
