Large circles represent assessment sites in open basins and small circles represent coastal assessment sites. Additionally, HELCOM (HELCOM 2017), proposed a set of biodiversity indicators to asses the biodiversity status in the sub-basins of the Baltic Sea, (see Fig. Copepods are food for organisms at higher trophic levels, such as fish, auks and Greenland whales, while copepods' faeces are food for benthic animals. Especially three species of copepods, Caianus hyperboreus, C. glacialis, and C.finmarchicus, create the basis forthe high marine biodiversity in Disko Bay (Boertmann, Mosbech, Schiedek, & Dunweber, 2013; Garde, 2014).
