SLU Sail drone 2018-2021

During the late spring and summer of 2020, the SLU Aqua Sailor drone sails between the great Swedish islands of Öland and Gotland and collects data on the amount of fish and zooplankton. The drone survey partly takes place at the same time as the fisheries survey Sprat Acoustic Survey (Spras). Spras collects information on herring and sprat in the Baltic Sea, and is carried out with the research vessel R/V Svea. By matching data from Spras with data from the sailing drone, the researchers hope to gain better knowledge of how the Baltic Sea ecosystem works. This was repeated in 2022-2023. In 2019, SLU Aqua Sailor was used around the islands Karlsöarna in the Baltic Sea during 42 days between April and July 2019. The same survey took place In 2020 and 2021
