Guidelines and best available techniques for submarine tailings disposal in Norwegian fjords: Recommendations from the NYKOS project.
The NYKOS project aimed at addressing some of the main knowledge gaps on the environmental impacts of submarine tailing disposal (STD) to facilitate the development of techniques, practices and management measures that will minimize such impact. Here, we report on the main issues addressed by the di...

On the use of random walk schemes in oil spill modelling
In oil spill models, vertical mixing due to turbulence is commonly modelled by random walk. If the eddy diffusivity varies with depth, failing to take the derivative of the diffusivity into account in the random walk scheme will lead to incorrect results. Depending on the diffusivity profile, the re...
Numerical analysis of boundary conditions in a Lagrangian particle model for vertical mixing, transport and surfacing of buoyant particles in the water column
Lagrangian particle models are used for many applications in the ocean sciences, including transport modelling of oil spills, fish eggs and larvae, plastics, and sediment particles. In the context of oil spill modelling, there are numerous papers discussing entrainment of surface oil by breaking wav...
Embryonic exposure to produced water can cause cardiac toxicity and deformations in Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) larvae
Regular discharges of produced water from the oil and gas industry represents the largest direct discharge of effluent into the marine environment worldwide. Organic compound classes typically reported in produced water include saturated hydrocarbons, monoaromatic and polyaromatic hydrocarbons (MAHs...
Improving oil spill trajectory modelling in the Arctic
As petroleum development and other activities move further north, the potential for oil spills in ice-covered waters is of great concern. As a tool for contingency planning and forecasting during response, oil spill models play a key role. With the development of new, high-resolution coupled ice-oce...
Resiliency of a healthy fish stock to recruitment losses from oil spills
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...
