Based on nutrient and phytopigment data obtained during two cruises in the Ross Sea, two distinct groups were recognised. The first one was characterised by moderate nutrient (nitrate and silicic acid) depletions in combination with relatively high diatom and <i>Phaeocystis</i> abundance. The second group showed very low nutrient depletions and very poor diatom abundance. Average depth specific nitrate depletions were 8.1 and 1.1 µM and average silicic acid depletions were 21.5 and 1.3 µM, respectively. The nutrient consumption patterns did not match the conditions of silicic acid excess (SEA) or nitrate excess areas (NEA), a clear trend being probably obscured by very poor seasonal maturity of several sampling stations. The contrast between both groups is largely explained by small differences in nitrogen uptake regime of the major phytoplankters. During early season, the diatoms meet the majority of their nitrogen requirements by nitrate uptake, with few exceptions where ammonium is the most important nitrogenous substrate. On average, their nitrate uptake capacity is lower than that of <i>Phaeocystis</i> (average specific nitrate uptake rates were 0.021 and 0.036 day<sup>-1</sup> for diatoms and <i>Phaeocystis</i>, respectively). The latter phytoplankton always shows predominance of nitrate uptake. Both groups are subject to inhibition of nitrate uptake when ammonium availability increases, and it is likely that the diatoms are more sensitive to the inhibitory effect of ammonium.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Nutrient depletions in the Ross Sea and their relation with pigment stocks","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:31:38.441946","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Ross Sea; nutrient depletions; phytopigments","OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2022-02-17","DateCreate":"2006-10-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000165666700010","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0924-7963(00)00067-1"},"refs":null,"anarec":{"AnaID":103160,"PubliDate":2000,"Pagination":"195-208","XtraPublOfAnaID":null,"ISBN":null,"Volume":"27","Issue":"1-3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43079,"SerRR":"Journal of Marine Systems.
