Macrofauna showed an abundance of 4500 specimens per m²; the corresponding biomass was 10.7 g ash-free dry weight per m². The bivalve <i>Arctica islandica</i>, with 12 specimens per m² contributed 7.2 g to this biomass. Average meiofauna numbers, 0.9·10<sup>6</sup> per m² were low; a meiofaunal biomass of only 0.3 g was estimated. Depending on the method applied, large variations in metabolic activity were found. Results from shipboard incubation experiments probably present a large underestimate. The <i>in situ</i> bell-jar experiments showed an average oxygen uptake of 1010 µmol O<sub>2</sub>·m<sup>-2</sup>·h<sup>-1</sup>, equalling a carbon demand of 7.3 gC·m<sup>-2</sup>·month<sup>-1</sup> in May. ETS measurements gave a 3 times higher estimate. Taking into account that macrofaunal and meiofaunal abundance and biomass, as well as bottom temperatures, show minimum values in spring, an annual carbon mineralization by the benthic system of 50 to 70 gC·m <sup>-2</sup> is suggested. This would mean that about one third of the total primary produced organic matter is channelled into the benthic system.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biomass and activity of benthic fauna on the Fladen Ground (northern North Sea)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1986,"MonPub":null,"DateUpdate":"2019-07-05","DateCreate":"2001-08-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1986E116200021","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":14783,"PubliDate":1986,"Pagination":"313-323","XtraPublOfAnaID":null,"ISBN":null,"Volume":"20","Issue":"2-3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
