Description

NODC Accession 0112635 includes site samples and biological data collected aboard the LAURENCE M. GOULD during cruises LMG0106 and LMG0205 in the South Pacific Ocean from 2001-08-06 to 2002-09-09. These data include PIGMENTS, SPECIES IDENTIFICATION - LIFE STAGE and SPECIES IDENTIFICATION - WET WEIGHT. The instruments used to collect these data include net - plankton net. These data were collected by Langdon Quetin and Robin Ross of University of California-Santa Barbara as part of Southern Ocean GLOBEC. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-07-25. The following is the text of the abstract provided by BCO-DMO: "Winter ecology of larval krill: quatifying their interaction with the pack ice habitat" The goal of the larval krill studies was to investigate the physiology and ecology of krill larvae associated with the pack ice and the microbial community on which they feed. During LMG0106 we occupied two 4-5 day ice stations (Robert and Billy) and sampled several other ice floes opportunistically. We conducted 10 instantaneous growth rate experiments, and 4 whole body clearance time experiments to determine gut passage time (decline in pigment content over time). We also sampled larvae at two additional sites for initial body pigment content (whole body fluorescence), and at 4 sites for condition factor. The under-ice algal community was sampled at one site. Length and stage frequency determinations were also determined. We occupied three time-series stations of approximately 1 week each, and in addition opportunistically sampled at times when other activities had priority. Our primary goal during the cruise was to occupy three ice camps or process stations with the intent of thoroughly studying the under-ice environment by SCUBA in conjunction with other projects working topside.
