In particular, understanding the magnitude and patterns of natural variability in biological populations will help gauge any potential effects of future oil and gas activities. The Arctic climate exhibits variability on several scales relevant for Arctic ecosystem processes, from seasonal changes to decadal oscillations, but the linkages to biological processes remain largely speculative, at least over longer time scales. Benthic communities may be valuable in determining the impacts of environmental variability on Arctic marine ecosystems because benthic fauna are stationary as adults and communities integrate environmental processes over long time periods. Marine bivalves, which are long-lived and comprise a large proportion of benthic communities in the Arctic, have great potential as proxies for environmental variability and concomitant biological responses. Bivalve shell growth has been shown to reflect changes in regional environmental parameters such as temperature and precipitation as well as food availability.<\/jats:p>\n               <jats:p>We analyzed growth rates of the circumpolar Greenland smooth cockle, Serripes groenlandicus based on external, annually-deposited growth lines, and linked growth patterns to decadal-scale environmental variations in the Norwegian-Russian Arctic area of the Barents Sea and Svalbard. The dataset of 53 individuals spanning 117 years from 1878-1995 from different regions of the Barents Sea, Svalbard and other locations in the Russian high-Arctic is comprised of samples from Russian Arctic expeditions from the archives of the Zoological Institute (Russian Academy of Science, St. Petersburg). Absolute growth rates differed among regions, reflecting differences in environmental conditions, but at all sites growth had an oscillatory patterns, with several years of higher growth followed by multiple years of poorer growth. Preliminary analyses of environmental control on ecosystem structure reveal that the growth rates of bivalves in the Pechora Sea are strongly and negatively correlated to the NAO, indicating mechanisms of bio-physical coupling in the region.<\/jats:p>","DOI":"10.2118\/111558-ms","type":"proceedings-article","created":{"date-parts":[[2008,4,15]],"date-time":"2008-04-15T10:03:46Z","timestamp":1208253826000},"source":"Crossref","is-referenced-by-count":1,"title":["Arctic
