PhD Candidate in bio-optics and ocean colour remote sensing

NIVA is seeking an industrial PhD candidate in satellite remote sensing, ocean colour, and bio-optics. The project will evaluate bio-optical contributions to light variability in Norwegian fjords and coastal waters and develop improved satellite-based algorithms. A key focus is linking pelagic light conditions to biological, hydrological, and climate-driven processes (e.g. coastal darkening) to support environmental monitoring and biodiversity assessment.

The candidate will be part of the Department of Data Science and work in an interdisciplinary team across NIVA, including the Oceanography and other relevant sections. The position is a 3-year full-time appointment, with the possibility of a 1-year extension (25% research assistant). The candidate will be enrolled in the PhD programme at the University of Bergen (UiB) and participate in research stays with the Optical research group at the Department of Physics and Technology.

The primary workplace will be Bergen, however, Oslo may be considered for the right candidate. The role includes travel to NIVA’s regional office in Copenhagen.

Arbeidsoppgaver

About the project

The project aims to improve understanding marine optical properties and how pelagic light conditions in Norwegian fjords are changing, what drives these changes, and how they affect marine ecosystems. It will investigate interactions between biological, hydrological, and climate-related processes, with particular emphasis on coastal darkening and land–sea connectivity.

The satellite data used will be focused on the European Copernicus satellites Sentinel-2 and Sentinel-3 with possibilities for collaboration on other international or Norwegian satellite or drone sensors in connection with ongoing research projects. The candidate will have the opportunity to collect in situ data and lab analyses dedicated to the research questions within the project, with a focus on bio-optical parameters and light attenuation for algorithm developments and environmental studies both though NIVAs facilities and with the University of Bergen.

There are other possible synergies with applied projects, e.g. focusing on the use of satellite remote sensing data for monitoring of water quality under the Water Framework Directive and other ecological applications. Strong international collaboration in satellite remote sensing, bio-optics and coastal darkening is offered through e.g. the ISOLUME (IndicatorS Of changing Lightscapes in Underwater Marine Ecosystems) JPI Oceans project.

The preferred starting date is 01.09.2026.
