Biomass and catch composition of mesopelagic fish and invertebrates in the North Atlantic, June 2021

Catch data for macroplankon trawls from IMR cruise 2021105, covering large areas of the North Atlantic in June, 2021. The dataset contains trawl data from hauls dedicated to catching macroplankton and micronekton, using specialised, fine-meshed, non-graded trawls. All data presented are from oblique hauls, and is given as total catch biomass for all taxonomic groups (at different taxonomic resolutions, with some species identified and some organisms only identified to coarser taxonomic levels) in the catch, on a format compatible with the ICES trawl-acoustic database.
