Acute and physical effects of water-based drilling mud in the marine copepod Calanus finmarchicus
Farkas, Julia; Yvonne Bådsvik, Camilla; Altin, Dag; Nordtug, Trond; Olsen, Anders Johny; Hansen, Bjørn Henrik (Journal article; Peer reviewed, 2017)The aim of this study was to investigate impacts of fine particulate fraction of a commonly used barite-containing drilling mud on the pelagic filter feeding copepod Calanus finmarchicus. The results show that the tested ... -
Cellular level response of the bivalve Limecola balthica to seawater acidification due to potential CO2 leakage from a sub-seabed storage site in the southern Baltic Sea: TiTank experiment at representative hydrostatic pressure
Sokołowski, Adam; Świeżak, Justyna; Hallman, Anna; Olsen, Anders Johny; Ziółkowska, Marcelina; Øverjordet, Ida Beathe; Nordtug, Trond; Altin, Dag; Krause, Daniel Franklin; Salaberria, Iurgi; Smolarz, Katarzyna (Journal article; Peer reviewed, 2021-11-10)Understanding of biological responses of marine fauna to seawater acidification due to potential CO2 leakage from sub-seabed storage sites has improved recently, providing support to CCS environmental risk assessment. ... -
Combined effects of exposure to engineered silver nanoparticles and the water-soluble fraction of crude oil in the marine copepod Calanus finmarchicus
Farkas, Julia; Cappadona, V; Olsen, Anders Johny; Hansen, Bjørn Henrik; Posch, Wilfried; Ciesielski, Tomasz Maciej; Goodhead, Rhys; Wilflingseder, Doris; Blatzer, M; Altin, Dag; Moger, Julian; Booth, Andrew; Jenssen, Bjørn Munro (Journal article; Peer reviewed, 2020-10)While it is likely that ENPs may occur together with other contaminants in nature, the combined effects of exposure to both ENPs and environmental contaminants are not studied sufficiently. In this study, we investigated ... -
Developmental effects in fish embryos exposed to oil dispersions – the impact of crude oil micro-droplets
Hansen, Bjørn Henrik; Salaberria, Iurgi; Read, Kari; Wold, Per Sverre; Hammer, Karen Marie; Olsen, Anders Johny; Altin, Dag; Øverjordet, Ida Beathe; Nordtug, Trond; Bardal, Tora; Kjørsvik, Elin (Journal article; Peer reviewed, 2019-09)During accidental crude oil spills and permitted discharges of produced water into the marine environment, a large fraction of naturally occurring oil components will be contained in micron-sized oil droplets. Toxicity is ... -
Exposure of juvenile turbot (Scophthalmus maximus) to AgNP-EE2 mixtures: Implications on contaminant bioavailability and plasma steroid hormone levels
Farkas, Julia; Salaberria, Iurgi; Styrishave, Bjarne; Stanková, Radka; Ciesielski, Tomasz Maciej; Olsen, Anders Johny; Posch, Wilfried; Flaten, Trond Peder; Krøkje, Åse; Salvenmoser, Willi; Jenssen, Bjørn Munro (Journal article; Peer reviewed, 2017)Combined exposure to engineered nanoparticles (ENPs) and anthropogenic contaminants can lead to changes in bioavailability, uptake and thus effects of both groups of contaminants. In this study we investigated effects of ... -
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 ... -
Medium-term exposure of the North Atlantic copepod Calanus finmarchicus (Gunnerus, 1770) to CO2-acidified seawater: effects on survival and development
Pedersen, Sindre Andre; Hansen, Bjørn Henrik; Altin, D; Olsen, Anders Johny (Journal article; Peer reviewed, 2013)The impact of medium-term exposure to CO2-acidified seawater on survival, growth and development was investigated in the North Atlantic copepod Calanus finmarchicus. Using a custom developed experimental system, fertilized ... -
Transcriptional profiling of reproductive development, lipid storage and molting throughout the last juvenile stage of the marine copepod Calanus finmarchicus
Tarrant, Ann; Baumgartner, Mark; Hansen, Bjørn Henrik; Altin, Dag; Nordtug, Trond; Olsen, Anders Johny (Journal article; Peer reviewed, 2014-12-16)Introduction Calanus finmarchicus, a highly abundant copepod that is an important primary consumer in North Atlantic ecosystems, has a flexible life history in which copepods in the last juvenile developmental stage (fifth ...
