Malta has taken a major step forward in marine science and environmental monitoring with the launch of BLUE (Buoy for Long-term Underwater Exploration); the country’s first fixed ocean sensing platform. This state-of-the-art system marks a new era in oceanographic research and represents a significant investment in Malta’s marine infrastructure.

BLUE is anchored 3.7 kilometres off the Grand Harbour and is equipped to provide continuous, high-resolution data on both marine and atmospheric conditions. Its launch brings Malta in line with international standards for marine monitoring and supports national obligations under the EU Marine Strategy Framework Directive (MSFD) and the Water Framework Directive (WFD).

BLUE’s capabilities are impressive: atmospheric sensors measure wind speed, temperature, humidity, and pressure; surface instruments monitor currents and wave conditions; and a motorised winch lowers sensors to 85 metres to collect detailed data on sea temperature, salinity, oxygen levels, CO₂, and more. This integrated system will provide crucial insights into climate change effects and human impact on marine ecosystems.

Special recognition goes to Dr. Adam Gauci, whose dedication over the past three years was instrumental in making BLUE a reality. Thanks, are also due to the University of Malta’s Finance and Project Support Offices, including Stacy Goodlip, for their vital contributions.

With BLUE now operational, Malta strengthens its role in regional marine research, setting the foundation for more informed environmental policy and sustainable ocean management.
