From oil spills to invasive species: Lagrangian modelling of connectivity in the Arctic Ocean
Marine connectivity describes the spatial and temporal linkages between separated parts of the global ocean. How different regions are connected, on what timescales, and by which oceanic pathways are important questions for a wide variety of applications. Answering these questions is an inherently i...

Marine connectivity describes the spatial and temporal linkages between separated parts of the global ocean. How different regions are connected, on what timescales, and by which oceanic pathways are important questions for a wide variety of applications. Answering these questions is an inherently interdisciplinary problem, with techniques including in-situ observations, remote sensing, and modelling used in synergy to answer key scientific questions. Here, a modelling approach is employed to contribute to our understanding of the wider field. This thesis focuses on understanding the importance of marine connectivity in the Arctic Ocean. The Arctic is a particularly important part of the global ocean, not least because of the impacts of climate change and loss of sea ice. This presents both challenges and opportunities - for instance, the retreat of Arctic sea ice is increasing interest in exploiting the region for resource extraction and commercial shipping, and changing circulation associated with a warming Arctic may permit invasive species to traverse the ocean.
