The experiments were carried out in the area of maximum salinity 80 km W of Den Helder. In March oxygen percentages of 101 % were found; an incomplete 48 h curve was constructed and a net oxygen production of 1.4 g. m<sup>-2</sup> .d <sup>-1</sup> was estimated (0.4 g C.m<sup>-2</sup>.d<sup>-1</sup>). In April, during calm weather and high solar irradiance, a mean oxygen percentage of 118% in a <i>Phaeocystis</i> bloom was found. A 72 hours oxygen curve showed a regular diurnal rhythm from which a daily oxygen increase of 3.2% was computed. Maximum hourly production values increased linearly from day to day. Net and gross O<sub>2</sub> production values were 11.0 and 14.2 g. m<sup>-2</sup>. d<sup>-2</sup>, corresponding with C values of 2.4 and 3.2 g. m<sup>-2</sup>. d<sup>-1</sup>. The importance of oxygen exchange with the atmosphere was discussed. A community carbon production for the period 11 March to 17 April of 24 g.m<sup>-2</sup> was assumed. Heterotrophs will play a significant role in community metabolism. Horizontal variability appeared to be a disturbing factor in obtaining consistent diurnal curves. Vertical oxygen gradients can play a part in exchange studies in well-mixed regions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Primary and community production in the Southern Bight of the North Sea deduced from oxygen concentration variations in the spring of 1980","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":1982,"MonPub":null,"DateUpdate":"2019-10-23","DateCreate":"2001-07-31","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1982PW52000023","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":14372,"PubliDate":1982,"Pagination":"247-259","XtraPublOfAnaID":null,"ISBN":null,"Volume":"16","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
