Description
Summary:Harbor area were described by analysis of their cell membrane phospholipid ester-linked fatty acids (PELFA) and metabolic rates. Analysis revealed a biomass averag-ing 6 nM (phospholipid) or 3.5 x 10 8 cells per gram dry weight (gdw) of sediment for the four sites. Only slight biomass differences were detected between the four penin-sula sites. All Arthur Harbor sites were determined tohave a biomass similar to the lowest amount reported for a previously described McMurdo Sound site at New Har-bor. Community structure based on signature phospholi-pids indicated only slight differences between the four peninsula sites with greater elative amounts of diatom marker lipids at a deeper site. Bacterial biomarker lipids were also determined in relatively equal proportions for the four Arthur Harbor sites with only one site indicating
