Sigurd Øxnevad has a masters degree in zoology (cand.scient) from the University of Oslo. Øxnevad works mainly with marine monitoring projects. He is invovled in projects such as monitoring of contaminants in coastal waters of Norway, screening of new contaminants, monitoring according to the water frame directive, risk assessment of contaminated sediments and environmental impact assessments. He has been project leader of several projects and has extencive experience from field work and sampling. He has been personnel safety representative, and until 2015 he was responsible person for NIVAs animal research facilities.
