Bakgrunn

Doktorgrad (ph.d) i fysiologi ved Institutt for Biologi, NTNU i 2008. Post doc, Forsker og Universitetslektor ved institutt for Biologi, NTNU i perioden 2008-2014.

Forskning

Min forskning er inntrettet på å forstå hvordan antropogene prosesser som havforsuring og klimaendringer vil påvirke marien organismser og deres økosystem. Jeg er spesiellt interesert i:

  • Å sette klimaendringer i sammenheng med andre stressfaktorer som mattilgang og miljøgifter
  • Å forstå effekter av miljøendringer på livssyklusnivå
  • Fenotypisk og genotypisk plastisitet
  • Fysiologiske og molekylære mekanismer

Effects of ocean acidification scenarios and combined stress on the copepod Calanus finmarchicus (2010-2014)

This reserch project on effects of ocean acidification (2010-2014) was funded by the Norwegian Reserch Council and was coordinated by NTNU in collaboration with, SINTEF Materials and Chemistry, SINTEF Ficheries and Aquaculture and Biotrix.

The main objective of the project was to assess how near future ocean acidification scenarios may affect the ecologically important marine copepod "Raudåte" (Calanus finmarchicus). This species is linking the energy transfer between primary producers and higher level organisms like fish. At times, of the Norwegian coast, in may constitute up to 90% of the standing stock of zooplankton. In addition to studies focusing on ocean acidification studies aimed at investigating combined effects from raising seawater temperature (global warming) and different food regimes was also performed. The empirical date generated by the experiments have been feed into into population modelling studies to allow us to address the socio-economic impacts of future ocean conditions on this species.

Experimental equipment needed for the different experiments was designed and assembled. A custom gas mixing system has been developed to deliver stable and accurate flow of five different future atospheric CO2 scenarios. This system is implemented at the experimental facilies at NTNU SeaLab.

A dedicated CO2 lab is finished and several experiments have been successfully conducted. The CO2 lab houses a system compising 14 tanks (90L) comitted to  CO2 perturbation experiments of long duration.

The experimental system is currently used in an expreiment on the combined effect of ocean acidifiation and rising temperature on the deep water squat lobster Munidopsis serricornis, an imporant component of the cold water reefs. The project is a collaboration between NTNU and Johanna Järnegrene at NINA.
