The device consists of a yellow houlographic buoy of 40 cm in diameter, as well as 2 orange floats. The data collected automatically by the device are available in real time via the website: www.reeftemps.science/wavebuoy  They are intended primarily for scientists (Météo-France NC forecasters from, IRD / SPC oceanographers), for monitoring large wave events and for validating wave models, oceanic current circulation and coastal flooding models, but also for fishermen, marine pilots and, of course, surfers.

Until now, New Caledonia has benefited from very occasional and isolated wave measurement observations. The installation of this device will make it possible to better observe and understand the phenomena related to the swell. This system is considered experimental, as the quality of the data will be analyzed with some caution before deploying other similar systems in the Pacific region. Sea users crossing the area are asked not to disturb this measuring device.

Similar devices have been or will be installed in Fiji, Tuvalu and Kiribati. This project is funded by the World Meteorological Organization (for Fiji, Tuvalu and Kiribati), and by the Ministry of Europe and Foreign Affairs via the Pacific Fund (for New Caledonia).
