The depth distribution of Ostracoda from the Greenland Sea

Abstract

Abstract. Sixteen box core samples of Recent sediment collected in three transects across the East Greenland shelf and slope were analysed for Ostracoda. The samples which range in depth from 274 m to 3355 m, yielded a total of 52 species belonging to 25 genera. No less than 26 of the species also occur in the adjacent Scoresby Sund fjord complex. The fauna represents an interesting mixture of high latitude shallow water Arctic species and others known from bathyal and abyssal depths in the North Atlantic, including some pandemic deep sea species. Many species occur in shallower water here than in the North Atlantic due to the colder water. The fauna comprised of three associations (Shelf/Upper Slope; Slope: Lower Slope/Abyss). A marked faunal turnover occurs at the Upper Slope. The study raises questions concerning the constancy and universality of the relationship between certain ostracod species and water masses.

“…There are a few more studies on taxonomy and distribution of North Atlantic deep−sea ostracodes (Rosenfeld and Bein 1978;Benson et al 1983;Cronin 1983;Dingle and Lord 1990;Coles et al 1996;Alvarez Zarikian 2009). In the Nordic Seas, Whatley and his colleagues inten− sively studied Greenland Sea deep−sea ostracods in the late 1990s Whatley et al 1998). Apart from taxonomic stud− ies, Quaternary fossil deep−sea ostracodes have been investigated in several deep−sea sediment cores both from the North Atlantic Ocean and Nordic Seas for paleoceanographic and paleoecological reconstructions (Cronin et al 1999;Didié et al 1999Didié et al , 2002Didié and Bauch 2000;Cronin et al 2002;Alvarez Zarikian et al 2009;Yasuhara et al 2009b).…”

Cold-seep ostracods from the western Svalbard margin: direct palaeo-indicator for methane seepage?

“…In addition, although deep-sea ostracods from normal soft sediments are well studied in the North Atlantic, Nordic seas, and Arctic Ocean (i.e. adjacent regions to the study sites) (Whatley and Coles, 1987;Whatley et al, , 1998Didié and Bauch, 2000;Yasuhara et al, 2009Yasuhara et al, , 2014aAlvarez Zarikian, 2009;Okahashi, 2014, 2015;Gemery et al, 2017), any similar species or genus to Rosaliella svalbardensis has not been reported. Van Harten (1993) suggested that pore clusters in Xylocythere is related to ectosymbiosis of chemoautotrophic bacteria (also see Maddocks, 2005).…”
