Stable isotope ratios of C and N in benthic macrofauna from Mediterranean seagrass litter accumulations from Calvi Bay in 2011-2012

Abstract

Measurements of trophic markers performed in benthic macrofauna sampled in seagrass litter accumulations from Calvi Bay (Corsica, France) in 2011-2012. more This dataset contains measurements of stable isotope ratios of carbon and nitrogen made in 568 individual specimens of 19 different taxa of benthic macrofauna (Nemertea, Mollusca, Polychaeta, Crustacea, Actinopterygii). Samples were taken in submerged seagrass litter accumulations, seasonally in 2011-2012, and at two sites of Calvi Bay (Corsica, France). Analytical measurements were performed at University of Liège (Belgium)’s stable isotope facility (Laboratory of Oceanology, Stable Isotope in Environmental Sciences and Trophic Ecology workgroup, https://www.oceanobio.uliege.be/). More info about the studies and sample preparation can be found in the publications referenced below. The dataset consists of two files: one containing the data itself, and one describing all used terms (measurements or metadata, derived from Darwin Core standards, https://dwc.tdwg.org/terms/).
