Pacific Arctic Stable Isotope Synthesis [Dunton]



This dataset is a synthesis of carbon and nitrogen stable isotope data from several studies collected into a single GIS feature class. The data cover the Pacific-influenced coastal shelf ecosystem of the Arctic Ocean. Data points include isotopic ratios of del C-13 and del N-15. Additional metadata such as the names of the original data collectors are included as attributes of the feature class when available. Carbon isotope ratios are a good indicator of carbon sources of the food web because of their small enrichment steps between consecutive consumers (0-1 0/00) and nitrogen isotope ratios are good indicators of trophic level (TL) because of the larger enrichment step of 3-4 0/00 between TL. This dataset is part of the Pacific Marine Arctic Regional Synthesis (PacMARS) Project.
