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

Master project title:

Effects of terrestrial inputs on community composition of softbottom benthos in Isfjorden, Svalbard.

Master project description:

Benthic community composition is determined by a variety of abiotic factors, which vary on regional and local scales. In Svalbard fjords, benthic communities are subject to a range of environmental conditions, ranging from disturbed inner basins where glacial melt water brings freshwater and heavy loads of sediments, to deep saline waters in the open fjord. Increased terrestrial run-off from a warming Arctic landscape is delivering freshwater and inorganic sediments (and associated nutrients and organic matter) to coastal areas, with implications for local benthic community structure and functioning. This MSc project focuses on benthic community distribution in Isfjord in relation to physical parameters of the water column and sediments. Soft-bottom macrofauna samples will be collected using a Van-Veen grab along inner to outer fjord transects in Billefjord, Tempelfjord and Adventfjord in the Isfjord fjordsystem and community composition will be analyzed in relation to abiotic factors.ThisMSc project is a part of the TerrACE project (NFR project from 2017–2021; PI: Amanda Poste, NIVA).

I work in highly seasonal environments and study the scheduling of annual events and the trade-offs involved. Key traits: reproduction, energy storage, dormancy and migrations. What is the scope of state-dependent responses? What is the role of phenotypic plasticity versus evolution? Most of my work is on the ecology and evolution of birds, fish and zooplankton using mathematical models and statistical analyses of data. An important component of my work is to use the insights we gain to understand and predict how organisms respond to environmental variability and change, with pollution, harvesting and climate change as central stressors.
