PhD Project title:

Using Unmanned Aerial Vehicles (UAVs) for marine mammal surveys in Arctic and sub-Arctic regions.

PhD Project description:

The petroleum industry is interested in developing sound environmental approaches to perform their exploration and development activities in Arctic regions. Top predators are a key component of the Arctic ecosystem. Given the climatic restrictions to access in these areas, it has been difficult to make routine assessments of the seasonal distributions and abundances of top predators. This has accelerated the technological development of new image acquisition systems for use in combination with UAVs (Unmanned Aerial Vehicles). The combination of image acquisition systems deployed by UAVs may lead to substantial improvements in the routine assessment of top predators in their natural habitats and, in particular, in their behavioral reactions to industrial activities.

Therefore, the principal objective of this PhD project is to assess the survey capabilities of UAVs to detect and monitor marine mammals. Different image acquisition systems will be used and assessed in order to determine the most appropriate technology to be deployed on UAVs for marine mammal surveys. This will serve as a test case for the application of UAVs for general marine mammal surveys. The research will help establish new technological approaches for mitigating the effects of anthropogenic activities in the marine environment. This PhD project will examine whether and how UAVs may be used to understand the seasonality and distribution of marine mammals in locations with potential for seismic exploration activities to be performed. UAVs may provide assistance in the preparation for seismic exploration, considering both the timing and optimal location for operations. In addition, the project will examine the performance of UAVs in relation to traditional marine mammal detection methods, such as passive acoustics and ship/land-based observations.

In this project, computer simulations with tagging data will be developed to better understand the data that should be acquired by the UAV, testing different scenarios of transects (flight patterns), and environmental conditions. This will allow us to determine the optimal operational procedure for monitoring behavior and assessing animal distribution under various scenarios. Taken together, this PhD project will lead to improved understanding of the uses and capabilities of UAVs outfitted with image acquisition systems for applications of direct relevance for the environmental management of petroleum operations in Arctic regions.

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.

PhD Project title:

Reproduction in Polar Cod: a study of the potential effects of anthropogenic activity on the reproductive success of an Arctic keystone species.

PhD Project description:

The first part of my study will primarily investigate reproductive strategy of polar cod, a keystone species in the Arctic ecosystem, and characterize physiological changes and reproductive development of polar cod in relation to their environment.  The second part will be expanded to a circumpolar scale as polar cod are found in every shelf sea of the Arctic, clearly demonstrating a successful strategy for Arctic domination. The ability of polar cod to reproduce during the cold, dark and food limited Arctic winter is believed to be a major factor in their success. This begs the question of how polar cod and their reproductive success will fair as the Arctic ecosystem is under pressure from climate change, human activities, and poleward moving competitors. This study will be focused in the Arctic and Atlantic influenced waters around Svalbard and expand to the American and Canadian Arctic waters.

An ecotoxicological component will also be included to explore the sensitivity of early life stages chronic levels of waterborne petroleum on important developmental checkpoints. This work expands upon two studies on adult polar cod sensitivity to acute and chronic exposure to crude oil, dispersed oil and burned oil residues.
