Simple energy-budget model for yolk-feeding stages of Atlantic cod (Gadus morhua)
Atlantic cod (Gadus morhua) is a commercially important species, and therefore, understanding the influence of environmental factors and anthropogenic stressors on its early life stages is of considerable relevance. In this contribution, we apply a simple and generic energy-budget framework (DEBkiss...
Toxicokinetics of Crude Oil Components in Arctic Copepods
The risk of accidental oil spills in the Arctic is on the rise due to increased shipping and oil exploration activities, making it essential to calibrate parameters for risk assessment of oil spills to Arctic conditions. The toxicokinetics of crude oil components were assessed by exposing one lipid-...

Toxicokinetics in Arctic copepods
Assessing impacts of simulated oil spills on the Northeast Arctic cod fishery
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...
NUMERICAL INTEGRATION AND INTERPOLATION IN MARINE POLLUTANT TRANSPORT MODELLING
In situ characterisation of complex suspended particulates surrounding an active submarine tailings placement site in a Norwegian fjord
Suspended particle measurements over flood and ebb transects of a Norwegian fjord (Frænfjorden) with an active submarine mine tailings placement are presented. Measurements focused on characterisation of spatial variability in particle and floc size, and determination of suspended mine tailing conce...
Effects and uptake and excretion kinetics of 11 selected PAHs in Arctic lipid rich copepods
Increased ice cap melting is opening up new areas in the Arctic to human activities such as oil exploration. Offshore oil production releases large quantities of hydrocarbons into the marine environment, notably as produced water and oil droplets. The PWC-Arctic project endeavors to assess the poten...
Dynamic Links between Lipid Storage, Toxicokinetics and Mortality in a Marine Copepod Exposed to Dimethylnaphthalene
Efficiently assessing and managing the risks of pollution in the marine environment requires mechanistic models for toxic effects. The General Unified Threshold model for Survival (GUTS) provides a framework for deriving toxicokinetic-toxicodynamic (TKTD) models for the end point survival. Two recur...
