The transect along the 85°W meridian comprised seven stations that progressed from solid pack-ice (70°S), through melting ice into open water (67°S). The abundance, biomass and taxonomic composition were determined for each component of the microbial community. The phytoplankton was mostly dominated by diatoms, particularly small (&lt;20 μm) species. Diatom abundance ranged from 66 000 cells l<sup>−1</sup> under the ice to 410 000 cells l<sup>−1</sup> in open water. Phytoplankton biomass varied from &lt;1 to 167 mg C m<sup>−3</sup>, with diatoms comprising 89–95% of the total biomass in open water and autotrophic nanoflagellates comprising 57% under the ice. The standing stocks of autotrophs in the mixed layer ranged from 95 mg C m<sup>−2</sup> under the pack-ice to 9478 mg C m<sup>−2</sup> in open waters. Bacterial abundance in ice-covered and open water stations varied from 1.1 to 5.5×10<sup>8</sup> cells l<sup>−1</sup>. Bacterial biomass ranged from 2.4 mg C m<sup>−3</sup> under pack-ice to an average of 14 mg C m<sup>−3</sup> in open water. The microzooplankton consisted mainly of aloricate oligotrich ciliates and heterotrophic dinoflagellates and these were most abundant in open waters. Their biomass varied between 0.2 and 54 mg C m<sup>−3</sup> with a minimum at depth under the ice and maximum in open surface waters. Microheterotrophic standing stocks varied between 396 mg C m<sup>−2</sup> under pack-ice and 3677 mg C m<sup>−2</sup> in the open waters. The standing stocks of the total microbial community increased consistently from 491 mg C m<sup>−2</sup> at the ice station to 13 155 mg C m<sup>−2</sup> in open waters, reflecting the productive response of the community to ice-melt. The composition of the microbial community also shifted markedly from one dominated by heterotrophs (82% of microbial stocks) at the ice station to one dominated by autotrophs (73% of microbial stocks) in the open water. Our estimates suggest that the microbial community comprised &gt;100% of the total particulate organic carbon (POC) under the ice and 62–66% of the measured POC in the open waters.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Microbial community structure in the marginal ice zone of the Bellingshausen Sea","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:31:36.754292","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2021-02-17","DateCreate":"2005-09-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000077463500007","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0924-7963(98)00031-1"},"refs":null,"anarec":{"AnaID":76195,"PubliDate":1998,"Pagination":"87-96","XtraPublOfAnaID":null,"ISBN":null,"Volume":"17","Issue":"1-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43079,"SerRR":"Journal of Marine Systems.
