Master thesis title:

The distribution of seabirds in the Southern Ocean: abundance, density and variability in time and space.

Master thesis description:

Growing interest in the ecosystem services offered by the Antarctic ecosystem is demonstrated in the wish to expand krill fishery and in increasing tourism. These factors together with a changing climate pose new pressures on a pristine environment and its inhabitants. Distribution data on marine predators is necessary for conservation to be successful and crucial in establishing time and site-specific fishing quotas, where harvest levels are adjusted with respect to predator needs. Hurtigruten vessels MS Midnatsol and MS Fram were used as platforms of opportunity for collecting distribution data on marine mammals and seabirds around the West Antarctic Peninsula, in The Drake Passage and around the Falkland Islands and South Georgia in December 2019 and January 2020. In my master’s thesis, the data analysed will be limited to seabirds, and the goal is to estimate their abundance in time and space in the Scotia Sea. The distribution data will be related to different environmental variables to find the factors that describe the variation in seabird abundances and densities on a spatial as well as a temporal scale.
