Summer mesozooplankton distribution near Novaya Zemlya (eastern Barents Sea)

Spatial variations in reproductive characteristics of the small copepod Oithona similis in the Barents Sea

“…Spatial trends in O. similis biomass were associated strongly with water temperature (Table 3). Similar patterns have been observed for O. similis in the southern and eastern Barents Sea (Dvoretsky 2008, Dvoretsky & Dvoretsky 2009a, O. davisae in Fukuyama Harbor (the Inland Sea of Japan) (Uye & Sano 1998), O. nana in Southampton Water (Williams & Muxagata 2006) and Oithona spp. in the Irminger Sea (Castellani et al 2007).…”

Regional differences of mesozooplankton communities in the Kara Sea

“…For example, high abundances of bottom animal larvae in the southern Barents Sea and in the White Sea are observed in May-June (Timofeev, 2000;Berger and Kosobokova, 2001). At the same time, in more eastern and northern Arctic regions the maximum rates of zooplankton/meroplankton reproduction and development may be shifted to late June, mid-July or August, as is the case in the Pechora Sea (Dvoretsky and Dvoretsky, 2009d), in Novaya Zemlya coastal waters (Dvoretsky and Dvoretsky, 2009c) and in Franz Joseph Land Archipelago waters (Dvoretsky and Dvoretsky, 2011b;Dvoretsky, 2011). Fetzer (2003 has reported that release of planktotrophic larvae of bottom fauna occur mainly at the time of phytoplankton bloom in the Kara Sea.…”

Summer bacterio- and zooplankton in coastal waters of Svalbard

“…Zooplankton was sampled in the bottom-0 m or 100-0 m layers with a Juday net. Pro cessing of zooplankton samples was performed by the standard methods; the number was counted per one cubic meter; biomass was calculated using the tables of standard weights and length-weight regressions [7] and then converted into carbon units. The mean val ues are presented with the standard error (±SE).…”
