ENVINET Activities Catalog

ENVINET Activities Catalog

ENVINET (European network for arctic-alpine multidiciplanary environmental research) is a research infrastructure network focusing on multidisciplinary environmental research in Europe. The network involves representatives from 18 environmental research infrastructures from the European Alps to the Arctic, representatives of their users and representatives from relevant international organizations and networks. The participating infrastructures cover a broad range of environmental sciences primarily within atmospheric physics and chemistry as well as marine and terrestrial biology.

The ENVINET project directory covers data and observation activities at these stations.

Other catalogs through this service are AMAP, SAON and SEARCH, or refer to the full list of projects/activities.

1. Long-term effects of offshore discharges on cold water zooplankton: establishing a test system for chronic exposure to offshore discharges

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.

2. Environmental effects of offshore oil activities: experimental tests of petroleum-associated components on benthos at community, individual, and cellular levels

This project will examine benthic processes in arctic and mid-latitude regions in order to derive specific conclusions on the sensitivity of benthic organisms and communities to acute spills of petroleum-related chemicals and routine releases of drill cuttings. We will carry out a series of controlled experiments on whole sediment communities and individual benthic organisms with additions of drill cuttings and petroleum-associated contaminants, arriving at a set of hypotheses on the likely impacts on the benthos of petroleum production activities at higher latitudes. A series of testable hypotheses will be formulated based on an examination of real-world monitoring data sets collected under Norway’s Petroleum Regional Monitoring Programme and results of mesocosm experiments performed previously at the Norwegian Institute for Water Research (NIVA) Station at Solbergstrand. These data sets will be examined in order to identify the geographic scope of responses to petroleum industrial activities. Through this work, we intend to propose procedures to improve the interpretation of benthic monitoring data for diverse environmental regions in Norway. The project is linked to several on-going NFR projects within the Polarklima programme. By involving a Ph.D. student the project will advance the education and training of young scientists in the field of biological effects studies related to petroleum development and exploration activities.

3. Interactions among infauna, microorganisms and polycyclic aromatic hydrocarbons in marine sediments

Dose-response experiments using 5 different sediment concentrations of fluoranthene (Flu) and pyrene (Py) respectively. Measuring radioactive marked Flu and Py in brittlestars and polychaetes and microbial degradation of Flu and Py in sediment. Also growth rate of brittlestars and polychaetes and determination of regenerationtime of brittlestar-arms.

5. Environmental sensitivity of cold water corals

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?
