    Catch data for macroplankon trawls from IMR cruise 2013107, covering large areas of the North Atlantic in May and June, 2013. 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.Some Abstract

  • The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Portuguese Ground Fish trawl survey.

    The dataset contains integrated values of total and mesopelagic backscatter for an EK60 38 kHz echosounder, from ~25 to 1000 m depth, collected during May 2019 during a Norwegian cruise aimed at mapping mesopelagic resources. Data is based on integration of data cleaned with automatic filters using KORONA, and manual cleanup of remaining problems (false bottoms etc.). All backscatter deeper than 200 m were then assigned to the mesopelagic category, with backscatter shallower than 200 m reported in the total category.

  • The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Irish Ground Fish trawl survey.

  • The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Spanish North Coast Bottom Trawl Survey.

  • The dataset includes age- and length-based catch per unit effort data for commercial fish species from IBTS in ICES roundfish areas in the North Sea.

  • The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Northern Irish Ground Fish trawl survey.

  • The dataset includes age- and length-based catch per unit effort data for commercial fish species collected by the French trawl survey EVHOE.

  • Collated substrate data in the Irish Designated Shelf Area. Substrates are classified using modified Folk categories facilitating an easy transition to EUNIS. Survey and classification techniques depend on the original source/data creator of the individual component subsatrate maps that make up the entire dataset. Data contributors include the Marine Institute (Ireland), Geological Survey of Ireland, INSS, INFOMAR, HabMap, Irish Sea Fisheries, National Parks and Wildlife Service, Coastal and Marine Research Centre, and the Joint Nature Conservation Committee (UK).

  • Marine litter data from DATRAS trawl surveys dataset includes references to the hauls made during survey cruises, and information about litter found during hauling.
