Tide gauges equipped to measure sea level and activity

(CNS): Four tide gauge stations have been installed in the three Cayman Islands to collect data on tidal activity and sea level. The gauges have been installed at Gun Bay Public Dock in East End, Royal Watler Cruise Terminal in George Town, Creek Dock in Cayman Brac and Bloody Bay Dock in Little Cayman. They have been funded by the UK government and will help improve the accuracy of tidal forecasts and measure sea level rise.

Prime Minister Wayne Panton, who is Minister for Sustainability and Climate Resilience, explained the importance of equipment in shaping future policy in the face of rising and changing seas.

The global record of sea level tide gauges is an important indicator of the evolution and impact of climate change,” he said. “Data collected locally from these gauges will provide important information to the Cayman Islands government that will inform our risk mitigation measures as we build resilient infrastructure for our islands.”

The public is asked not to touch or tamper with the gauges, which have two sensors. One is a “float” in a tube that rises and falls with the water level, while the other is a radar gauge measuring the height of the water from the sensor. The gauge will be plotted in the local geodetic system to help understand its precise location (latitude, longitude and altitude).

Data collected from tide gauges will be used to measure sea level change over time to understand the impact of climate change as well as the impact on tides during extreme weather events such as barometric pressure high/low and storm surge and tidal influence. on coastal ecosystems.

The information will be used to improve vessel navigation for safe transit and port entry, port operations, improving links between vertical reference frames and reducing seabed mapping data to define Datas.

“Investments like these are very valuable and important in improving our way of life,” said Juliana O’Connor-Connolly, Minister of Lands. “I strongly urge our community members not to tamper with these tide gauges and risk invalidating potential data that will support the prosperity of our islands. The data provided by the tide gauges will not only improve safety of navigation, but will contribute to a better understanding of the tides in the wider Caribbean region.

The Lands and Surveys Department has also announced its intention to contribute the data to the International Oceanographic Commission’s Global Sea Level Observing System, which supports a wide range of data uses and feeds into the Intergovernmental Coordination Group for the Warning System for Tsunamis and Other Coastal Hazards. for the Caribbean and adjacent regions (ICG/CARIBE-EWS).
