Accumulation of organic compounds was observed with dissolved organic carbon (DOC) and particulate organic carbon (POC) reaching 717 and 470 µM C, respectively and transparent exopolymeric particles (TEP) up to 3,071 µg Xanthan gum equivalent l<sup>-1</sup>. POC and TEP seemed to be inXuenced mainly by algae. Particulate saccharides accounted for 0.2–24.1% (mean, 7.8%) of POC. Dissolved total saccharides represented 0.4–29.6% (mean, 9.7%) of DOC, while dissolved free amino acids (DFAA) accounted for only 1% of DOC. Concentrations of TEP were positively correlated with those of saccharides. Monosaccharides (d-MCHO) dominated during winter–early spring, whereas dissolved polysaccharides did in spring–summer. DFAA were strongly correlated with d-MCHO, suggesting a similar pathway of production. The accumulation of monomers in winter is thought to result from limitation of bacterial activities rather than from the nature of the substrates.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Distribution and characterization of dissolved and particulate organic matter in Antarctic pack ice","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-20 01:31:56.324055","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Sea ice · Organic carbon · Monosaccharides · Polysaccharides · Amino acids · TEP","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2014-06-19","DateCreate":"2012-10-26","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000265298800006","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00300-008-0577-y"},"refs":null,"anarec":{"AnaID":219438,"PubliDate":2009,"Pagination":"733-750","XtraPublOfAnaID":null,"ISBN":null,"Volume":"32","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
