Directory entires that have specified Norwegian Sea as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada).

During the last decade the concern regarding environmental effects of the offshore industry has shifted from effects of drilling discharges on benthic communities, towards a stronger focus on the water column and effects on the pelagic ecosystem. At the same time, oil and gas development is expanding in the Norwegian and Russian sectors of the Barents Sea. In this regard, a project has been initiated to look at responses of especially Calanus spp. and other copepod species to long-term, sublethal exposure to selected offshore discharges and discharge components, as well as accidental oil spills. Calanus spp. is ecologically the most important zooplankton species along the Norwegian shelf and in the Barents Sea. A laboratory based facility for culture through several generations is being developed through this project. In addition, the impact of oil compounds on the cold-water and arctic Calanus species-complex will be examined by carrying out a series of laboratory (some at Ny Ålesund) and ship based experiments. The response parameters will include both behavioral (feeding, mate finding, avoidance) and physiological (mortality, egg production, development rates, oxygen consumption and assimilation efficiency) parameters. The ultimate outcome of this research is expected to be a supporting instrument for ecological risk assessment of offshore discharges, which is highly relevant both to the North Sea, the mid-Norway shelf and the Barents Sea.
Distribution • What is the current distribution of coral colonies in the North Sea? • Where are coral colonies located on the structures? • Do any colonies show evidence of exposure to drill cuttings? Monitoring & Environmental Recording • What hydrodynamic regime and levels of suspended particulate material are coral colonies exposed to? • Does the coral skeleton retain an archive of any past contamination? • Does skeletal growth vary over time and does this correlate with any past contamination? • How variable is the rate of coral growth and does this correlate with any environmental variables? Environmental Sensitivity • What effect does increased sediment load have on coral behaviour and physiology? • What effect does exposure to discharges (e.g. cuttings and produced water) have on coral behaviour and physiology? • Are such exposures realistic in the field?
