Intra-season variations in distribution and abundance of humpback whales in the West Antarctic Peninsula using cruise vessels as opportunistic platforms
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-09)Fine-scale knowledge of spatiotemporal dynamics in cetacean distribution and abundance throughout the Western Antarctic Peninsula (WAP) is sparse yet essential for effective ecosystem-based management (EBM). Cruise vessels were used as platforms of opportunity to collect data on the distribution and abundance of humpback whales (Megaptera novaeangliae) during the austral summer of 2019/2020 in a ... -
Large-scale seabird community structure along oceanographic gradients in the Scotia Sea and northern Antarctic Peninsula
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-18)Introduction: The Scotia Sea and Antarctic Peninsula are warming rapidly and changes in species distribution are expected. In predicting habitat shifts and considering appropriate management strategies for marine predators, a community-level understanding of how these predators are distributed is desirable. Acquiring such data, particularly in remote areas, is often problematic given the cost ... -
Mapping seabird vulnerability to offshore wind farms in Norwegian waters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-13)Introduction: Offshore wind energy development (OWED) has been identified as a major contributor to the aspired growth in Norwegian renewable energy production. Spatially explicit vulnerability assessments are necessary to select sites that minimize the harm to biodiversity, including seabird populations. Distributional data of seabirds in remote areas are scarce, and to identify vulnerable areas, ... -
Seabird guild composition and distribution relative to biophysical cues throughout the Antarctic Peninsula and Scotia Sea
(Master thesis; Mastergradsoppgave, 2021-08-16)Seabird distributions reflect physical and biological features of the marine environment and their variability on different spatial and temporal scales. Different species assemblages are associated with specific oceanic habitats and concentrations of birds typically occur in areas of high biological productivity. Here I explore seabird distributions and habitat use relative to biophysical cues of ...
