Title Sources of primary production, benthic-pelagic coupling, and trophic relationships within the Northeast Water Polynya: Insights from δ13C and δ15N analysis Type Journal Article
Year 1995 Publication Marine Ecology Progress Series Abbreviated Journal Mar Ecol Prog Ser
Volume 128 Issue 1-3 Pages 1-10
Keywords phytobenthos; polynyas; carbon 13; nitrogen isotopes; food webs; check lists; trophic structure; Algae; PNE, Greenland, Northeast Water Polynya
Abstract We used stable carbon (13C/12C) and nitrogen (15N/14N) isotope analysis to investigate linkages between sources of primary production and the pelagic and benthic components of the Northeast Water (NEW) Polynya off northeastern Greenland. Ice algae was enriched in 13C (mean δ13C = -18.6 vs -27.9 ppt) and 15N (mean δ15N = 8.3 vs 4.9 ppt) over particulate organic matter (POM) suggesting that the relative importance of these sources might be traced isotopically. Most grazing crustaceans and filter-feeding bivalves had δ13C and δ15N values in the range of -21 to -23 ppt and 7 to 9 ppt, respectively, indicating a direct pathway from POM. Close benthic-pelagic coupling was also confirmed for other benthic organisms examined with the exception of the predatory or deposit feeding echinoderms Ophiocten, Ophiacantha and Pontaster. Compared with other Arctic and temperate marine food webs, stable-carbon isotope values for the NEW Polynya were depleted in 13C. A δ15N trophic model that incorporated taxon-specific isotopic fractionation factors indicated that the NEW Polynya consisted of 4.5 to 5 trophic levels. Stable-isotope analysis may be well suited to establishing the importance of polynyas as sites of high primary productivity and tight benthic-pelagic coupling relative to regions of more permanent ice cover.
