Key qualifications

Experimental marine ecotoxicology. I have broad experience from planning, conducting and reporting long-term continuous flow experiments studying reproductive effects and biomarker responses in invertebrates and fish exposed to a range of compounds mainly related to discharges from the offshore oil and gas industry.

Our Research on Ocean Acidification

I am presently working with the effects of ocean acidification in two projects; NORKLIMA/HAVKYST no#200800/S40 "Combined effects of ocean acidification, climate change and oil related discharges" (where I am project leader) and the Institute anchored Strategic Project (ISP) “Effects of ocean acidification on invertebrate calcifying larvae” led by Ingrid C. Taban. We have built up an exposure system for continuous flow exposure to seawater with reduced pH (increased pCO2). This year the system was extended and optimized for doing flow-through experiments with sea urchin larvae. In the period from 2009-2011 we have performed long term experiments with shrimps, mussels, deep water corals and sea urchin early life stages. Part of this work has been published and presented at international conferences (see details below). Preliminary results from a sea urchin larvae experiment we performed this spring will be presented at the 7th Alexander von Humboldt International Conference in Malaysia, June 20-24, by Sam Dupont, who is partner in our RCN 200800/S40 project. Our PhD student Maj Arnberg is co-author on this presentation. In addition to this Ingrid C. Taban (project leader for the ISP on ocean acidification) and I wrote two articles about ocean acidification for the newspapers; ”Det andre CO2 problemet” published in Stavanger Aftenblad in 2009 and ”Klimaskader på reker og blåskjell” published in Dagens Næringsliv in 2010. There was also and article about our RCN project in CICERO’s journal Klima - Norsk magasin for klimaforskning (http://www.cicero.uio.no/Klima/10/3/Klima10-03.pdf). In addition to the conference presentations I have presented our ocean acidification research to CICERO (invited lunch presentation); in a meeting at the Fram Centre in Tromsø (Flaggskip Havforsuring i nordlige farvann); to the North Sea Commission, General Assembly when they visited Stavanger in 2010 and to several oil companies (2009-2010).

I have participated in many projects financed by the oil industry, and most of these projects have been confidential. Hence the results have only been presented in research reports. I have not included these reports in the CV.


    More details about our work with
    ocean acidification will come soon!

    Reproduction experiments, life table experiments
    and early life stage tests with crustaceans
  • Life table experiments with the harpacticoid copepod Tisbe furcata exposed to copper; isolation of the species from field samples, culturing of the copepod, and development of an appropriate test system for doing (semi static) life table experiments with copepods exposed to toxic compounds (Master thesis).
  • Reproduction experiments and acute tests with the copepod species Acartia tonsa, Nitocra spinipes and Tisbe furcata, in addition to acute tests with Daphnia magna, and reproduction test with a marine amphipod (pilot experiment) (NIVA)
  • Life table experiments with the harpacticoid copepod Tisbe battagliai to study the effect of nickel in the sediment (PhD).
  • Life table experiments, and experiments over two generations, to study the effects of nonylphenol on Tisbe battagliai (PhD).
  • Reproduction test with the amphipod Chaetogammarus marinus exposed to TBT in a flow through exposure system (IRIS).
  • Early life stage tests with shrimp larvae (Pandalus borealis) (IRIS). Mortality and development time during chronic exposure to oil.


Reproduction experiments and early life stage tests with fish

Sheepshead minnows (Cyprinodon variegatus)


Long-term continuous flow experiments studying reproductive effects and biomarker responses in fish exposed to:
  • Dispersed oil
  • Naphthalene
  • Chrysene
  • A mixture of PAHs
  • A mixture of alkylphenols

These experiments have been planned, conducted and reported in cooperation with Ingrid C. Taban, and with Steinar Sanni as project leader.




Parameters:
  • PAH metabolites in bile
  • DNA adducts
  • VTG and Zrp
  • Condition factor
  • Egg production
  • Hatching success
  • Survival of larvae

Spotted wolffish (Anarhicas minor)

Survival and growth of spotted wolffish larvae exposed to off-shore produced water.

Cod (Gadus morhua)

Survival, growth and feeding of cod larvae exposed to suspended particles of used water based drilling mud with barite as the weighting material.


DNA strand breaks measured by the Comet assay
I have used comet assay to study DNA damage in cells from animals exposed to potentially genotoxic compounds.

I have experience from the following species/cell types:

Haemocytes from mussels (Mytilus edulis) and scallops (Pecten maximus and Chlamys islandica)



Sperm from mussels and sea urchins.

Coelomocytes from sea urchins (Strongylocentrotus droebachiensis)

Erythrocytes from cod (Gadus morhua), polar cod (Boreogadus saida) and corkwing wrasse (Symphodus melops).




Muddy Waters;

Blues for water column organisms exposed to drilling mud discharges?
The 2004-2005 project:

“Impacts of drilling mud discharges on water column organism and filter feeding bivalves”.

Norwegian Research Council project no. 159183


The two main objectives were to study:

1. If exposure to suspended drilling mud particles affected

  • Cod (larvae and juveniles)
  • Blue mussels (larvae and adults)
  • Scallops (adults)

2. If metals accumulate in tissues of bivalves and fish after exposure to drilling mud

The 2006-2008 project:

“Drilling mud follow up study - Input data and validation experiments for ERMS”.

Norwegian Research Council project no. 173418


In PROOF project (159183) negative effects of barite and used water based drilling mud with barite were detected in cod, mussels and scallops. We will do follow-up experiments to:
  • contribute to the understanding of the metal vs particle effects of barite by comparing effects and metal concentration in mussels exposed to barite with high and low metal content
  • find out if the observed histological damage to cod and mussels exposed to barite is irreversible
  • test if cod fed barite exposed mussels accumulate metals

Because of its lower metal content ilmenite is considered to be a more environmentally friendly alternative to barite as a weighting material in drilling mud.
  • Adult scallops and mussel larvae will be exposed to ilmenite and used drilling mud with ilmenite to find out if ilmenite cause less effect than barite, and if the potential effects of ilmenite are irreversible.

” I’ve got mud in my eyes, baby …
…. mud stick to my gills
No one ask how it feels
The mud on my food
Breaks down my mood

200 tons each day
Tiny particles of ‘clay’
Spread far away
Are we really okay? “
