About the project

Three-year postdoctoral project, funded by the Icelandic Research Fund (grant number 196369) and Doctoral Project at the University of Edinburgh.

This research explores various practical implications of the theory of ambulatory baselines, and possibilities for stabilising otherwise fluctuating maritime limits. It explains how bilateral maritime boundaries are established, and how coastal instability and vulnerable ecosystems can affect the delimitation process through bilateral negotiations or judicial settlement. Finally, it explains how unforeseen, fundamental changes to the marine environment can lead to revision of settled maritime boundaries and related agreements.
