Narrative in attached cruise report.

FRV Solea left Cuxhaven on the 22nd of July 2020 and started its scientific program the following day. In general, the scientific program consisted of three days with 7 hauls per day within each box. Each day at least two CTD casts were deployed. The scheduled personnel exchange was carried out around noon of the 1st of August in Cuxhaven. The scientific program continued from the 2nd until the 11th of August. The vessel returned to Cuxhaven on the 11th of August 2020.
During this year's survey a total of 91 hauls with the cod hopper trawl net and an additional 26 accompanying CTD casts were conducted in five boxes of the GSBTS assigned to FRV Solea. In addition, an experimental box W and the vicinity of an offshore windfarm close to the island of Helgoland was sampled.
Like in previous years the actual sequence of sampling in the boxes was adapted to the prevailing weather conditions (Box H (British EEZ; 3 days), Box E (German EEZ; 4 days), Box N (German EEZ; 2 days), Box K (Danish EEZ; 2 days), and Box P (German EEZ; 1 day). Box F was omitted from this year’s survey due the experimental fishing around two offshore windfarms.
