A machine vision system for tracking population behavior of zooplankton in small scale experiments: a case study on salmon lice (Lepeophtheirus salmonis Krøyer, 1838) copepodite population responses to different light stimuli
To achieve efficient and preventive measures against salmon lice (Lepeophtheirus salmonis Krøyer, 1838) infestation, a better understanding of behavioral patterns of the planktonic life stages is key. To investigate light responses in L. salmonis copepodites, a non-intrusive experimental system...

Developmental effects of fuel oils on early life stages of atlantic cod (Gadus morhua)
The use of PAH, metabolite and lipid profiling to assess exposure and effects of produced water discharges on pelagic copepods
Several laboratory studies have demonstrated that exposure to oil components cause toxicity to copepods, however, this has never been shown in natural populations of copepods. In the present study, we sampled copepods in an area of the North Sea with high density of oil production platforms discharg...
Comparison of artificially weathered Macondo oil with field samples and evidence that weathering does not increase environmental acute toxicity
Macondo source oils and artificially weathered oil residues from 150 °C+ to 300 °C+, including artificially photo oxidized oils, were prepared and used for generating low energy water accommodated fractions (LE-WAFs) in order to assess the impact of oil weathering on WAF chemistry composit...
QSAR methodology for calculating impact on organisms exposed to dissolved oil in the water column - ERA Acute for water column exposed organisms - OC2020 A-030
ERA Acute uses results from an oil spill model to calculate impact from exposure to the spilled oil in the four compartments: sea surface, shoreline, water column and sea floor. The oil spill model is run in stochastic mode to combine the impact with a probablity for the impact to calculate environm...
Interaction between microalgae, marine snow and anionic polyacrylamide APAM at marine conditions
When an oil field ages and the pressure in the reservoir decreases, or for oil fields with heavy oil, there may be a need for enhanced oil recovery (EOR) technologies. Polymer injection is a water-based EOR method where the viscosity of the water injected for pressure support is increased by mixing ...
