| Remarks | Zooplankton were sampled with a vertically hauled HYDRO-BIOS Multiple Plankton Sampler MultiNet, type Midi (mouth aperture: 0.25 m^2) fitted with 150-μm mesh nets and programmed to collect stratified samples at the following depths: 0-50, 50-100, 100-200, 200-300, 300-500 and 500-1000 m. Taxon is most abundantly found in the 50-100 m depth interval. Samples were collected primarily during the Arctic summer, exact dates are estimated given information provided in the reference. | ||
