Sea-level monitoring in the British Overseas Territories

Abstract

A review is conducted on the status of sea-level monitoring in the British Overseas Territories (BOTs), showing where measurements have been made in the last two decades by various groups and thereby indicating where investments in future recording are needed. The sea level has risen in every territory since the early 1990s, and is predicted to increase by approximately 0.25–1.0 m by the end of the twenty-first century, depending on the emissions scenario. As a result, it is maintained that sea-level monitoring is needed in all BOTs, both for local coastal applications and as British contributions to the worldwide sea-level monitoring programme.
