Based on a simplified trophic network, that includes two size classes of phytoplankton and of zooplankton, and a microbial loop, it has been calibrated by reference to surface physical, chemical and biological data sets collected at the KERFIX time-series station (50°40′S–68°25′E). The model correctly reproduces the high nutrient low chlorophyll features typical of the studied area. In a region where the spring–summer mixed layer depth is usually deeper than 60 m, the maximum of chlorophyll never exceeds 1.5 mg m<sup>−3</sup>, and the annual primary production is only 68 g C m<sup>−2</sup> year<sup>−1</sup>. In the surface layer nitrate is never exhausted (range 27–23.5 mmoles m<sup>−3</sup>) while silicic acid shows strong seasonal variations (range 5–20 mmoles m<sup>−3</sup>). On an annual basis 71% of the primary production sustained by nanophytoplankton is grazed by microzooplankton. Compared to North Atlantic, siliceous microphytoplankton is mainly prevented from blooming because of an unfavourable spring–summer light-mixing regime. Silicic acid limitation (high half saturation constant for Si uptake: 8 mmoles m<sup>−3</sup>) also plays a major role on diatom growth. Mesozooplankton grazing pressure excerpts its influence especially in late spring. The model illustrates the efficiency of the silica pump in the Southern Ocean: up to 63% of the biogenic silica that has been synthetized in the photic layer is exported towards the deep ocean, while only 11% of the particulate organic nitrogen escapes recycling in the surface layer.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Modelling the silica pump in the Permanently Open Ocean Zone of the Southern Ocean","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:31:40.606785","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":"2005-09-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000077463500040","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0924-7963(98)00066-9"},"refs":null,"anarec":{"AnaID":76273,"PubliDate":1998,"Pagination":"587-619","XtraPublOfAnaID":null,"ISBN":null,"Volume":"17","Issue":"1-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43079,"SerRR":"Journal of Marine Systems.
