PhD project title:

Characterization of Zostera marina microbiome.

PhD project description:

My PhD project focuses on the microbiome of the eelgrass Zostera marina, present in the local fjord Kjerstadfjorden near Bodø. The first part of the project uses metagenomics to characterize the diversity of its microbiome (prokaryotes and micro-eukaryotes) in space and time, following several meadows with various environmental condition through the seasons. Secondly it investigates if the Zostera marina microbiome is influenced by its genotype. The last part of my research will focus on the functional roles of this community through various experiments (temperature stress and nutrient enrichment) via meta-transcriptome approach.

Start date: Sep 2015
End date: Autumn 2018

PhD project title:

Deep Fjord Benthos and Effects of Aquaculture.

PhD project description:

Aquaculture is one of the most profitable and fastest growing economic sectors in Norway, and is expected to continue expanding, particularly in northern fjords. It is well established that these fish farms can have adverse effects on the marine system in the immediate vicinity of the open cages. Recent findings have suggested, however, that fish farm waste spread over long distances with implications for areas previously believed to be unaffected. This project will attempt to trace fish farm waste through benthic food webs in deep fjord basins, as well as assess regional impacts of organic effluents on community structure and function.

Start date: Sep 2016
End date: Aug 2019

PhD project title:

An integrative study of the oceanographic conditions affecting marine ecology north of Svalbard, with special focus on the circulation, upwelling and carbon chemistry of Atlantic Water.

PhD Project description:

Atlantic water enters the Arctic Ocean as boundary current through Fram Strait and subducts under the lighter Arctic water upon entering the Nansen basin north of Svalbard. The circulation west and north of Svalbard is complex due to substantial spatial variability in topography as well as temporal variability in wind forcing, lateral exchange processes and eddies. Detailed knowledge of the variable flow has so far been limited due to lack of direct current observations with sufficient spatial and temporal coverage. During this Phd project, Acoustic Doppler Current Profiler, temperature and salinity data will be gathered (connected to the SI_ARTCTIC project) and analysed.

The ocean currents act as advective routes transporting heat, nutrients and plankton, but also impact the local and small-scale distribution of heat and biological material. The retreat of the Arctic sea ice cover exposes larger areas north of Svalbard to wind stress, potentially increasing the role of upwelling. The two processes of upwelling and advection are central to Arctic oceanography and ecology, and their interplay is subject to scientific debate. Whereas adjective changes often occur on multi-annual to multi-decadal time scales, upwelling events are usually associated with short-term variability in winds. The observational and additional model data will be used to investigate the role of upwelling along the shelf.
