About the project

Dr. Árnadóttir has been involved in several projects relating to law of the sea and the Arctic. Her research in this area has focused on agreed maritime boundaries, Iceland´s position as an Arctic State and security threats due to melting ice sheets. She has presented her findings at the Arctic Circle, UArctic Congress and at the Military University Institute, Portugal, as a participant in the NASDS 2022 project (North Atlantic Security and Defense Strategy).

Sea level rise and the melting of Arctic ice poses a security threat in the Arctic because it changes the extent of exclusive maritime entitlements and creates new navigational routes. Maritime limits are ambulatory in all parts of the world under the general interpretation of the Law of the Sea Convention but there are unique concerns in the Arctic due to rapid changes in the sea-ice coverage and the fact that maritime limit have, in some instances, been established along ice instead of terra firma.
