PhD project title:

Arctic pelagic and sympagic primary production – functional responses to climate change.

PhD project description:

I am investigating the seasonal and latitudinal dynamics in the primary production of phytoplankton and sea ice algae of the Northern Barents Sea, aiming to establish new baselines in a changing Arctic. I am particularly interested in applying molecular techniques to assess the functional responses of individual species or strains to multiple climate change stressors.

PhD project title:

Ocean acidification effects on planktic calcifiers and biological pump efficiency.

PhD project description:

My research focuses on the seasonal distribution of marine calcifiers and their contribution to carbon standing stocks and export production in the Northern Barents Sea. In particular, I am studying planktic foraminfiera, shelled pteropods and coccolithophores, which are located at the base of the food web and have been reported to have an important role on the carbon cycle by exporting inorganic and organic carbon from the surface, where they inhabit, to the seabed, when they die and sink. I am also particularly interested on studying them on the fossil record (short sediment cores) and use them as proxies to reconstruct the environmental conditions from the last 12000 years.

Research interests:

  • marine wildlife monitoring
  • animal ecology and behavior
  • new survey technologies.

My main interest in research concerns marine wildlife monitoring, specifically the utility of new survey technologies and animal ecology and behavior. My goals are to provide insights into the understanding of interactions with and within ecosystems considering top-predators and related trophic levels.

Current projects:

  • Postoc – Spatial and temporal analyses of marine mammal vocalizations using unmanned systems.
  • PhD – Unmanned aerial vehicles for marine mammal surveys in arctic and sub-arctic regions.

Summary of PhD project
Whales travel between vast areas and therefore require effective monitoring schemes that can inform management and conservation decisions. For mitigation of offshore operations, drones are proving to be an efficient tool to understand, and possibly minimize, the potential impacts of these activities on marine resources. In such conditions, fixed-wing powered drones are the best option given their long operational range. Additionally, in the Arctic there are many areas of difficult access and the conditions can make it challenging to conduct surveys using traditional methods. Drones seem to be more cost-efficient and safer to operate than other methods, particularly for marine mammal surveys.To investigate how fixed-wing drones perform in different conditions, we conducted 12 field trials during summer and winter in Tromsø (Northern Norway). The drones followed pre-designed tracks and took consecutive photos throughout the entire duration of the flights. After the flights, images were classified for environmental conditions, animal presence, and presence/absence certainty. The results in this study highlight the need for scientists to investigate not only how the technology has an impact on how we gather data but also how the study subjects can affect the amount and quality of data that we collect.

PhD project title:

Small copepods in high latitudes.

PhD project description:

My PhD will focus on different aspects of the zooplankton population dynamics in the high latitude ecosystems, with emphasis on the small copepod group. My interest is to comprehend their seasonal variation and ecological importance. For that purpose, I will use a combination of both field and laboratory studies to enlarge the shortage of information available for small copepods in the Northern waters.
