PhD project title:

Assessing the Functional Diversity of Benthic Communities using Metatranscriptomics.

PhD project description:

Marine benthic communities constitute an important part of the marine seafloor environment, as they are involved in a multitude of important ecological processes such as geochemical cycling and the distribution of pollutants. Studying these communities in situ and exploring their activity down to the gene level can reveal insights into their functional role within the benthic ecosystems. Our aim is to investigate the molecular profile of benthic communities exposed to organic effluents from aquaculture farms by comparing the expression levels of selected genes at impacted and non-impacted sites. We use a metatranscriptomic approach, i.e. the analysis of the complete RNA contents of benthic organisms contained within environmental samples.

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.

PhD project title:

Land-Ocean Interactions: Effects of terrestrial inputs on coastal food-web structure and contaminant trophodynamics in an Arctic fjord system.

PhD project description:

Increased terrestrial run-off in Arctic regions is one major impact of climate change. As temperatures and precipitation increase and permafrost and glaciers melt, coastal areas are experiencing increased levels of riverine inputs. These inputs bring water, sediments, nutrients, organic matter and contaminants across the land-ocean interface with a range of implications for coastal contamination and food-web ecology. As a PhD student at NIVA, I hope to define both the direct and indirect impacts of these terrestrial inputs on coastal food-web structure and contamination.

My PhD project will investigate the influence of terrestrial inputs on the flow of energy and contaminants in marine foods webs in Isfjord, Svalbard. It is part of a larger effort (the TerrACE project at NIVA) to quantify terrestrial inputs and impacts on the Arctic coastal system. My project has three main aims. Firstly, we will characterize the physicochemical conditions and response to terrestrial inputs along freshwater to marine gradients in Billefjord, Tempelfjord and Adventfjord. Secondly, we will distinguish between the utilization of terrestrial vs. marine energy sources along these gradients. Thirdly, we will determine how terrestrial inputs can directly and indirectly affect contaminant dynamics (Hg and PCBs) through effects on food sources, trophic pathways and nutritional quality of prey items.

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.

Master thesis title:

Taxonomic and functional diversity of soft-bottom benthic communities in Tysfjord: Northern Norways deepest fjord.

Master thesis description:

Most of the benthic ecological research efforts in Nordland have been focused on the continental shelf mainly due to management needs for the impacts of exploitation of oil reservoirs. Therefore, little has been done in coastal fjords. However, the increasing use of these areas as locations for coastal aquaculture (mainly Atlantic Salmon farming) demands increased knowledge about the ecological functioning of the fjords in order to monitor and manage impacts of these activities in the future. Fjords are generally dynamic and resilient systems subject to extreme gradients of environmental parameters. It is then of vital importance to provide an accurate description of the system if anthropogenic effects on biological communities are to be discerned from natural drivers. Only some fjords around Bodø have been investigated. The present study will investigate the soft-bottom benthic communities of the deepest fjord of northern Norway: Tysfjorden, a multibasin subarctic fjord with depths down to 725 m. Several aquaculture farms already operate in this fjord together with other industrial facilities (quarz and concrete factories). The main objective of the study is to identify the main patterns in community composition, taxonomic and functional diversity of soft-bottom benthic communities together with the prevailing environmental drivers along a “inner”-“outer” transect in the Tysfjord system.
