The impact of exposure timing on embryo mortality and the partitioning of PAHs when cod eggs are exposed to dispersed and dissolved crude oil
Nordtug, Trond; Olsen, Anders Johny; Wold, Per-Arvid; Salaberria, Iurgi; Øverjordet, Ida Beathe; Altin, Dag; Kjørsvik, Elin; Hansen, Bjørn Henrik (Peer reviewed; Journal article, 2022)During sub-sea oil spills to the marine environment, oil droplets will rise towards the sea surface at a rate determined by their density and diameter as well as the vertical turbulence in the water. Micro-droplets (< 50 ... -

Faksness, Liv Guri; Altin, Dag (SINTEF Ocean rapport;OC2019 A‐054, Research report, 2019-03-22)Flere drivstoffprøver fra havaristen Helge lngstad har blitt analysert mhp fysikalske egenskaper og kjemisk sammensetning: Diesel både fra nødlossing og tatt opp på sjø, samt en helikopterfuel som var samlet opp på sjøen. ... -
Maternal polycyclic aromatic hydrocarbon (PAH) transfer and effects on offspring of copepods exposed to dispersed oil with and without oil droplets
Hansen, Bjørn Henrik; Tarrant, Ann; Salaberria, Iurgi; Altin, Dag; Nordtug, Trond; Øverjordet, Ida Beathe (Journal article; Peer reviewed, 2017-08-25)Copepods of the genus Calanus have the potential for accumulating lipophilic oil components due to their high lipid content and found to filter and ingest oil droplets during exposure. As female copepods produce eggs at ... -
Microplastic dispersal behavior in a novel overhead stirring aqueous exposure system
Salaberria, Iurgi; Nadvornik-Vincent, Colette; Monticelli, Giovanna; Altin, Dag; Booth, Andy (Others, 2020-08)Using nominal dose metrics to describe exposure conditions in laboratory-based microplastic uptake and effects studies may not adequately represent the true exposure to the organisms in the test system, making data ... -
Modelling the dynamics of growth, development and lipid storage in the marine copepod Calanus finmarchicus
Jager, Tjalling; Salaverria-Zabalegui, Iurgi Imanol; Altin, Dag; Nordtug, Trond; Hansen, Bjørn Henrik (Journal article; Peer reviewed, 2017)Mechanistic models are essential tools for interpreting and predicting the consequences of a changing environment and stressors such as pollution on the life histories of marine organisms. Here, we apply the simple and ... -
Mortality and transcriptional effects of inorganic mercury in the marine copepod Calanus finmarchicus
Tollefsen, Knut Erik; Song, You; Høgåsen, Tore; Øverjordet, Ida Beathe; Altin, Dag; Hansen, Bjørn Henrik (Journal article; Peer reviewed, 2017-08-25)Inorganic mercury (Hg) is highly toxic to organisms including crustaceans and displays multiple toxic modes of action (MoA). The main aim of this investigation was to assess the acute and sublethal toxicity mediated by ... -
