Profile
Marianne Olsen is Research Director at NIVA with overall operational and scientific strategic responsibility for five of NIVA's research sections, and takes part in NIVA's leader group. Marianne holds a MSc in Marine Biology and a PhD in ecology, addressing ecological effects of polluted seabed.
As a researcher, she has worked with a wide range of pollution challenges including environmental contaminants, oil spills and plastic pollution, and she has extensive experience with monitoring, environmental risk assessments, mapping of sediment pollution and assessment of clean-up measures in contaminated seabed as well as stakeholder involvement.
She has work experience from industry as a researcher with projects related to the environmental effects of offshore oil and gas extraction and of various types of land-based process industry, and as a project manager and advisor to the environmental authorities related to polluted seabed. She has developed and led major research and assessment projects. In recent years, she has been heavily involved in the development of NIVA's portfolio of international aid-funded capacity development projects on chemical and plastic pollution, ocean accounting and marine spatial planning, particularly in Asia.
