Assessing impacts of simulated oil spills on the Northeast Arctic cod fishery

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1522946

We simulate oil spills of 1500 and 4500 m3/day lasting 14, 45, and 90 days in the spawning grounds of the commercial fish species, Northeast Arctic cod. Modeling the life history of individual fish eggs and larvae, we predict deviations from the historical pattern of recruitment to the adult populat...

Spatiotemporal Dispersal and Deposition of Fish Farm Wastes: A Model Study from Central Norway

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1511796

A spatially explicit coupled hydrodynamic-mass transport model system was used to simulate dispersal of particulate organic matter from Atlantic salmon (Salmo salar) farming in central Norway. Model setups of 32 m horizontal resolution were run for periods of up to 650 days for 3 sites of different ...

2017:00007 A - SubSea Dispersant lnjection (SSDI)- a "state of the art" and the need for further documentations

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1477952

The aim of this pre-project has been to give a "State-of the art" and describe the R&D challenges and documentation needed in order to perform robust NEBA (Net Environmental Benefit Analysis) where SubSea Dispersant Injection (SSDI) is included as an acceptable countermeasure option. In spill sc...

Potential impacts of mine tailing plumes on pelagic filter-feeders

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1363483

Deposition of mine tailings in fjords along the Norwegian coast is known to have ecological implications for benthic fauna, but little information is available on the potential impacts on pelagic organisms. Depending on local hydrology, deposition of tailings can result in plumes where the particle ...

Real-time Decision Support for Drilling Operations in Sensitive Areas

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1349328

Drilling operations produce particulate drilling matter which is often discharged on, or close to, the sea floor. Properties like grain size and composition of the discharged matter, and ocean currents, determine where and to what degree this matter will be spread on the sea floor and in the water c...
