| Objectives | The North Sea Ecosystem spring cruise has been run since 2006 by the Institute of Marine Research (IMR) as a multi-purpose survey, covering hydrography, chemistry, phytoplankton and zooplankton as well as fish eggs and fish larvae for the IMR projects 'Monitoring of climate and plankton in the North Sea Skagerrak', and 'Early life history dynamics of North Sea Fishes'. The survey area of the North Sea Ecosystem cruise 2018 includes both northern North Sea and the Skagerrak.
Objectives 1. To sample pre-selected stations along standard transects for physical, chemical and biological parameters in the Northern North Sea and Skagerrak. 2. To map the abundance, distribution and species composition of phytoplankton, zooplankton, and early life stages of fish (eggs and larvae). 3. To undertake two process studies (northwestern North Sea and Skagerrak) in order to investigate the spatial, vertical and diel distribution of fish eggs and larvae and their potential predators and prey. 4. To monitor radioactive contamination in Skagerrak. |
