No abstracts are to be cited without prior reference to the author.The Antarctic Ocean is a complex ecosystem including planktonic herbivores like krill, salps, copepods a s w ell a s c arnivores l ike a mphipods, c tenophores, c nidarians and which are f ed upon by birds, fish, squids, seals and baleen whales. Although there are many reports about the che mical com ponents of t he Antarctic krill species Euphausia superba, as w ell as f or calanoid copepods, which are key organisms in the planktonic food web of the Antarctic Seas, there is yet little inf ormation available on the bi ochemical c onstituents of ot her c ommon species, like pteropods, which are frequently found in planktonic hols in the Southern Ocean. To find out more about the feeding ecology as well as the trophic position of these organisms, zooplankton samples were taken during the SYSTCO expedition, and preserved in order to conduct biochemical analyses, more precisely estimating stable isotope ratios and identifying fatty acid ...
