Fatty acid & HBI

Abstract

Stable isotopes, fatty acids & HBIs of POM & main zooplankton taxa will be used to study coupling/de-coupling of sympagic and pelagic primary and secondary producers. In addition fatty acids (together with C/N ratios) will be used as a measure of food quality for the planktonic grazer communities and will be linked to on board grazing experiment. At all the process stations, water for POM-samples was collected at the depth of Chlorophyll maximum, in order to link suspended fatty acid with grazing experiments. Sample were collected for the dominating copepod species (Oithona similis, Metridia spp., Calanus spp.) and of otherzooplankton such as Ctenophores, Chaetognaths, krill, amphipods and appendicularians. This dataset contains the list of Fatty acid & HBI samples (but HBI was not in the Sample Type list so all samples are listed as Fatty acids. The stable isotopes are listed together with the Ecotox samples (sampled by Julia Giebichenstein).
