Research interests:
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:

Benthic faunal response to sub-seabed methane emissions offshore Svalbard.

PhD Project description:

Sub-seabed emissions from gas reservoirs provides the potential for chemosynthetically fueled ecosystems to form. Few studies have documented influence of submarine gas release in the Arctic and this project aims to examine the biological macrofaunal response, community structure and function from sub-seabed gas deposits. The project is part of CAGE (Center for Arctic Gas Hydrate, Environment and Climate) whose primary aim is to understand sources and sinks of methane from sub-seabed reservoirs to the atmosphere in perspective of Arctic climate change.

Start date: April 2014
Planned submission date: April 2018
