There were no considerable changes in zooplankton biomass between the seasons. Throughout the investigation, the average biomass for the entire region approximated to ca. 5 g dry weight (DW) m<sup>−2</sup> while station-to-station variation ranged with an order of magnitude (1-14 g DW m<sup>−2</sup>). Biomass of nauplii and small copepods (200-500 µm in body length) obtained from water bottles samples exceeded that from WP-2 net samples 1.5-6.6 times. The maximum abundance of this group reached 16×10<sup>5</sup> ind. m<sup>−2</sup> in the upper 100-m layer, suggesting a significant grazing pressure on phytoplankton. Spatial distribution of <i>Calanus</i> species and some selected species suggests that the zooplankton community composition was primarily affected by water mass circulation and bottom topography. Both the depth distribution of mesozooplankton and cohort progress in <i>Calanus finmarchicus</i> and <i>Calanus glacialis</i> revealed two waves of spring events. The first started in the southernmost area of the Barents Sea and the second nearby the Polar Front. Both developed towards the north.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Seasonal and spatial changes in biomass, structure, and development progress of the zooplankton community in the Barents Sea","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Barents Sea; zooplankton; depth distribution; seasonal changes; Calanus;development progress","OtherDescriptors":null,"Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2004-06-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000179499900008","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/s0924-7963(02)00173-2"},"refs":null,"anarec":{"AnaID":62405,"PubliDate":2002,"Pagination":"125-145","XtraPublOfAnaID":null,"ISBN":null,"Volume":"38","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43079,"SerRR":"Journal of Marine Systems.
