The presentation, Monday, of three advanced ocean monitoring buoys by the Caribbean Institute for Meteorology and Hydrology (CIMH) to the Ministry of Infrastructure, Ports, Services and Energy marks an important step in strengthening Saint Lucia’s climate resilience, marine research and weather monitoring capabilities.
The solar-powered buoys are equipped with temperature-sensing cables capable of collecting ocean temperature data at depths of between 20 and 25 metres below the sea surface. The systems transmit real-time information that supports weather forecasting, climate monitoring, marine ecosystem management and disaster risk reduction efforts in Saint Lucia and across the wider Caribbean.
A symbolic handover ceremony was held on Monday at the Ministry’s headquarters in Union and was followed by a technical training workshop facilitated by CIMH Technical Research Officer, Courtney Forde. Ministry personnel and representatives from marine and environmental organisations received hands-on training on the buoys’ technical specifications, deployment procedures, recovery operations and maintenance requirements.
One buoy is fitted with solar panels and a sensor string containing multiple temperature sensors positioned at different depths throughout the water column. Once deployed, the system continuously records surface, mid-depth and deep-water temperatures, providing valuable insights into changing ocean conditions.
The data collected will play a critical role in monitoring ocean warming and marine heatwaves, improving weather forecasts, enhancing understanding of tropical storm and hurricane development, and supporting fisheries and marine resource management. Because ocean temperature influences the distribution of fish, coral reefs and other marine life, the information will also assist agencies in tracking shifts in fish habitats, assessing coral reef health, detecting conditions that may lead to coral bleaching, and enhancing coastal and maritime safety.
