Concept information
Preferred term
XBT
Definition
- The Expendable Bathythermograph (XBT) has been used by oceanographers for many years to obtain information on the temperature structure of the ocean to depths of up to 2000 meters. The use of XBT's to measure the ocean's subsurface has significantly increased over the past decade. NOAA is actively participating in an international effort to increase the number of subsurface temperature observations in support of global oceanographic and climate studies. NOAA's XBT program (SEAS) currently supports about eighty voluntary observing ships (VOS). Observations from these vessels are collected and coded using the WMO bathy report format (JJYY) and transmitted via the GOES and INMARSAT C satellites. SEAS vessels are responsible for more than 14,000 XBT observations each year. Additional information available at "http://seas.amverseas.noaa.gov/seas/xbt.html" (en)
