02 Parading hoods

After the mesocosms had been deployed in the Kongsfjord (Svalbard) and the 50 cubic metres large bags lowered, the participants of the study install a hood on every unit. The plastic roofs prevent rain and snow from falling into the bags since large amounts of freshwater would alter the measurements. A positive side effect is that birds that like to rest on the floating devices cannot drop nutrients into the water.
