PhD Project title:

Underwater hyperspectral imaging: Methods for identification, monitoring and mapping of light regime and biogeochemical objects in polar regions.

PhD Project description:

The focus of my PhD research will be on developing methods for the use of Underwater Hyperspectral imaging for measuring the light regime under sea-ice and the identification, mapping and monitoring of sea-ice fauna and algae communities. These methods have the potential of making the mapping of arctic marine ecosystems more efficient and therefore contribute significantly to the main research focus of ARCTOS.

PhD project title:

Marine Aquaculture and the Environment: Effects of Multiple Nutrient Sources.

PhD project description:

Marine aquaculture is going to expand globally in the coming decades. Further expansion of this sector is, however, only sustainable if farms are managed according to the resilience and carrying capacity of coastal ecosystems.

An emerging problem that is still understudied is the effect of multiple nutrient sources, i.e. pollution from several farms in close vicinity and the additional impact of agricultural run-off from land. Therefore, our project will study ecosystem-wide effects of nutrient pollution from multiple sources by combining experimental and field studies. We will address the overarching question of how coastal ecosystems respond to multiple inputs of nutrients.

Start date: September 2015
End date: Autumn 2018
