Description:
We provide here a curated set of data containing representative length/size measurements of key macroplankton and mesopelagic fish collected by a Macroplankton trawl (~6 m x 6 m mouth opening, non-graded mesh with 3 mm light-opening) from cruises in the Norwegian Sea during the International Ecosystem Survey in the Nordic Seas (IESNS) in May to June 2019 and 2020. The collected material is obtained from standardized V-shaped hauls down to a maximum depth of about 1000 m, although some shallower V-hauls are included either to look at the vertically migrating mesopelagic organisms that enter the epipelagic domain during nighttime hours, or because of depth restrictions due to shallow bottom topography.
