The Expendable Bathythermograph (XBT) is an in situ probe that measures temperature throughout the water column. XBTs are deployed from vessels into the ocean and provide temperature profiles to depths of up to 1800 meters. Water depth can also be calculated because XBTs have a known fall rate. NOAA, in collaboration with other agencies, monitors a network of XBTs deployed along fixed routes or transects to enable global monitoring of ocean temperatures.
