Strong winds characterise this area. Wind-induced turbulent mixing was quantified by means of the root-mean square expected vertical displacement depth of cells in the water column, Zt. The light attenuation coefficient was used as a measure of the influence of the large amount of terrigenous particles usually present in the water column; 1% light penetration ranged between 30 and 9 m, and between 30 and 15 m for the inner and outer cove, respectively. Obvious differences between photosynthetic capacity [P*max; averages 2.6 and 0.6 µg C (µg chlorophyll-a)<sup>-1</sup>h<sup>-1</sup>] and photosynthetic efficiency {α*; 0.073 and 0.0018 µg C (µg chlorophyll-a)<sup>-1</sup>h<sup>-1</sup> [(µmol m<sup>-2</sup> s<sup>-1</sup>)<sup>-1</sup>]} values were obtained for both sites during low mixing conditions (Zt from 10 to 20 m), while no differences were found for high mixing situations (Zt>20 m). This suggests different photoacclimation of phytoplankton responses, induced by modifications of the light field, which in turn are controlled by physical forcing. Our results suggest that although in experimental work P*max can be high, wind-induced mixing and low irradiance will prevent profuse phytoplankton development in the area.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Primary production, light and vertical mixing in Potter Cove, a shallow bay in the maritime Antarctic","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":2002,"MonPub":null,"DateUpdate":"2019-08-28","DateCreate":"2007-12-12","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":117894,"PubliDate":2002,"Pagination":"117-124","XtraPublOfAnaID":null,"ISBN":"3-540-43218-3","Volume":null,"Issue":null,"BRefMon":117752,"BRefMonRR":"<b>Arntz, W.E.; Clarke, A.
