The data include species-specific jellyfish and comb jelly community data, encountered during the North Sea - Midwater Ring Net (MIK) survey [1]. The MIK survey targets ichthyoplankton and is conducted at night during the quarter 1 (Q1) International Bottom Trawl Surveys (IBTS). Presented data about the gelatinous macrozooplankton community stems from Danish (DTU Aqua), the Swedish (SLU), and German (TI) partners. A total of 158 stations were investigated using a MIK net (2 m diameter, 13 m long, 1.6 mm mesh size with 0.5 mm for net end and cod end) [2]. Samples were collected by double oblique hauls Data in brief111432https://www.ebi.ac.uk/biostudies/studies/S-EPMC11964673biostudies-literatureGelatinous macrozooplankton in the North Sea: Biodiversity and distribution pattern during winter 2023-Q1 dataset.PMC11964673Werner MMeffre MJensen CJDHuwer BNeumann HJaspers CfalseGelatinous macrozooplankton in the North Sea: Biodiversity and distribution pattern during winter 2023-Q1 dataset.The biodiversity and distribution of gelatinous macrozooplankton in the North Sea and adjacent waters during winter (January/February) 2023 is presented both quantitatively and qualitatively.
