Anguilla became the latest contributor to the IOC (Intergovernmental Oceanographic Commission) Sea level monitoring facility when the Department of Disaster Management installed a sea level monitoring device commonly known as a tide gauge at the Blowing Point Port in April.

The sea level monitor was funded by the Government of the United Kingdom and installed by Jerard Sea Level Systems with support from the National Oceanographic and Atmospheric Association (NOAA), the Department of Disaster Management and the Department of Lands and Surveys.

The tide monitor was purchased and installed based on a report from the ninth session of the Intergovernmental coordination group for the tsunami and other coastal hazard warning system for the Caribbean and adjacent regions held in St. Thomas USVI, May 2014. The report urged member states to continue their efforts to fill gaps in the monitoring networks (seismic and sea-level) towards the completion of the Tsunami and Other Coastal Hazards Warning System for the Caribbean and Adjacent Regions.
The tide monitor records the sea level in one minute increments and transmits the data to the Intergovernmental Oceanographic Commission of UNESCO (UNESCO-IOC) via satellite at five minute intervals.

Director of Disaster Management, Ms. Melissa Meade stated: "This tide gauge is hopefully just the beginning of Anguilla's contribution to improve sea level monitoring in Anguilla and the region for the purposes of early warning and monitoring of tsunami and other coastal hazards. With the support of other key partners and Departments we are seeking to be able to expand our sea level monitoring network in the future to include other points of the coast where the data collected can prove to be valuable. I would like to thank the UK Government for providing the system, NOAA and the Department of Lands and Surveys for their assistance in levelling and installation and the Anguilla Air and Seaports Authority for allowing us to install the equipment at the port."
