Cruise reports 2020

From 26.05 to 09.06.2020 an expediton wiht research vessel "Elisabeth Mann Borgese" to Fehmarnbelt - a marine protected area in the Baltic Sea - was conducted. The goal was to create a first comprehensive dataset on the state of sediments and biocoenoses in Fehmarnbelt. The data will be used as a baseline for comparisons with future investigations in Fehmarnbelt and other protected areas in the Baltic sea after the exclusion of mobile bottom fishing in the marine protected areas. Furthermore, samples were taken for comparisons outside the protected area. For sampling, multicorer was used for pore water, meiofauna and protists and Van Veen grabs and dredge for macrofauna. Also, the seabed was mapped using geoacoustic methods. By use of lander systems, in situ fluxes and biogeochemical turnover at the seafloor were measured.

Solea 777

From May 22 to June 4, 2020, the team from the Thünen Institute was onboard Solea to take samples in the Baltic Sea in the Natura 2000 areas Fehmarnbelt and Oderbank. The samples will be used to investigate changes in the benthic and demersal fish community before and after the exclusion of mobile ground-touching fishing gear.
 

Clupea 343

From July 6 to 22, 2020, an expedition with Clupea in the Baltic Sea took place to get samples from demersal and benthic fish fauna in the Natura 2000 sites of the German Exclusive Economic Zone (EEZ). The aim is a comparison of fish-samples before and after exclusion of mobile ground-touching fishing gears.
