Trawl catch data from Nansen Legacy Cruise - Arctic Basin Joint Cruise 2-2

Description

Trawl catch data from the Nansen Legacy Cruise - Arctic Basin Joint Cruise 2-2 in the Eurasian Basin during August-September 2021. Two pelagic trawls were used resulting in twelve trawl stations in pairs at six locations: eight stations with a Harstad trawl targeting pelagic fish and four stations with a macroplankton trawl for catching larger zooplankton. The Harstad 320 trawl is a standard Norwegian pelagic trawl for pelagic fish (capelin, herring and juveniles) in northern areas and was used with modified rigging. The modified rigging included wire instead of spectra sweeps (both 60 m long), reducing the total buoyancy of the trawl net (from 1047 kg to 50 kg), and applying 150 kg weights in front of each lower wing and a 40 kg weight at the end of the cod-end. The macroplankton 92 m trawl (trawl opening area of ~36 m2) was used with ordinary rigging, except that 40 kg weight was added at the back part of the cod-end. The macroplankton trawl is a non-graded trawl with 8 mm mesh opening (EN ISO 1107:2003) from the front of the trawl to the cod-end. More information about the trawling specifications and operations can be found in {add link when paper is published}. The data set include station information, trawl catch data (wet weight in g nm-1) and individual length measurements.
