©2020 Biological and Chemical Oceanography Data Management Office.This dataset includes size fractionated zooplankton, C:N, d13C, and d15N from EXPORTS cruise JC214 on RRS James Cook from May to June 2021.
Sampling was conducted during RRS James Cook cruise JC214 from May 1 to June 1, 2021 in the North Atlantic. Zooplankton were collected using a multiple opening-closing net and environmental sensing system (MOCNESS). Onboard, zooplankton were wet-sieved in filtered seawater using 0.2, 0.5, 1.0, 2.0 and 5.0 mm mesh sieves into different size fractions and frozen at -20º C. Zooplankton were dried and each fraction ground using a mortar and pestle. Samples were weighed into tin capsules and isotope ratios were determined using a Costech elemental combustion system coupled to an isotope ratio mass spectrometer through a Conflo-IV interface. For details please see Hannides et al. (2013).
