DEF

An untethered ocean buoy equipped with meteorological and/or oceanographic sensing instruments linked to transmitting equipment for sending the observed data to collecting centres.

CONT

The buoys in the network are comprised of both drifting buoys and moored buoys. "Drifters" are expendable systems launched from ships or aircraft into specific ocean areas. They collect data as they drift in response to ocean currents and winds. Since satellites that these "drifters" transmit to are not geostationary, data are only available when the orbiting satellite is within site of the buoy.

DEF

Bouée océanique non ancrée, équipée de capteurs météorologiques et/ou océanographiques et du matériel requis pour transmettre les données d'observation à des centres de collecte.

CONT

Les bouées dérivantes (flotteurs auxquels une ancre flottante, centrée à 15 mètres de profondeur, est attachée), sont utilisées pour mesurer le courant de surface grâce à leurs déplacements. [...] elles constituent un support pouvant recevoir un baromètre, voire un dispositif de mesure du vent. Les données de vent mesurées par de tels flotteurs permettent de calculer la part du courant due au vent (courant d'Ekman) et celle, à plus grande échelle, due à la rotation de la Terre (courants géostrophiques).
