Описание
Sampling was conducted during the Polar Night cruise 2017 (PNC17), 6th to 17th January 2017 in the waters of the western Barents Sea and Svalbard archipelago. Zooplankton was collected using a Multinet (64um-mesh) This dataset issued in the publication of Barth-Jensen et al. 2022

Географический охват
13 stations were sampled: Six oceanic stations: TB1 and TB2 (located in the western Barents Sea), NS1, NS4 and NS10 (located on the shelf north of Svalbard) and NS6 (located off the shelf north of Svalbard). Seven fjord stations: VMF9 (located near Bellsund, at the opening of Van Mijenfjorden), KF1, KF2 and KF3 (located in Krossfjorden on the west coast of Svalbard), and R3, R3b and R4 (located in Rijpfjorden on the northern coast of Nordaustlandet).

Методы сбора
Zooplankton was sampled using vertically stratified net hauls with a multiple opening/closing net (MultiNet type Midi, Hydro-Bios, Germany, mouth opening 0.25 m2, 64-µm mesh, towing speed 0.4 m s-1). The four depth strata sampled were 3-50 m, 50-100 m, 100-200 m and 200-400 m, or to 10 m above the bottom at stations shallower than 400 m. A 64-µm mesh WP-2 net (Hydro-Bios, Germany, opening 0.25 m2) was used for the 0-50 m sampling at station TB2 due to a tear in the MultiNet net bag. A technical error resulted in only the upper 100 m being sampled at station KF1.

Описание этапа методики:
- Immediately after collection the samples were fixed in hexamethylenetetramine-buffered formaldehyde in seawater solution at 4% final concentration. The samples were later analyzed under a stereomicroscope (Olympus SZX7). Organisms with total length > 5 mm were sorted from the sample, identified and counted. Then aliquots were taken with a 2-mL pipette with the tip cut at 5-mm diameter to allow collection of mesozooplankton. The number of aliquots and subsamples analyzed was chosen so that at least 300 individuals were counted in each sample. The remainder of the sample was screened for rare species. Species were identified to the lowest taxonomic level and classified as holoplankton or meroplankton. For copepods, a detailed analysis of copepodid stage composition was performed for Calanus spp., O. similis, M. norvegica, Pseudocalanus spp., M. longa and Microcalanus spp. The CI to CIII stages were not differentiated for Microcalanus spp. at station TB1, and for O. similis and M. norvegica at all stations. Early stages (CI to CIII) classified as Microcalanus spp. probably included young copepodids of Paracalanus spp., Clausocalanus spp. and Ctenocalanus spp., because it is difficult to distinguish these species via visual identification. The CI to CIII stages of M. longa and M. lucens were not differentiated, and were designated M. longa. The three Calanus species were differentiated on the basis of size (Kwasniewski et al. 2003); this involves some uncertainty because prosome lengths of species of the genus can overlap (Gabrielsen et al. 2012; Choquet et al. 2018). Copepod nauplii were determined to order (Calanoida, Cyclopoida and Harpacticoida).
