The Airborne EXpendable BathyThermograph (AXBT) measures ocean temperature as a function of depth. The temperature profiles nominally produced are from the surface to 350 m, at 1.5 m vertical intervals. During several joint missions by the University of Miami and NOAA in the Gulf of Mexico, these probes were deployed from a NOAA WP-3D aircraft .
The location of AXBT deployments (circles) for each mission are shown in the maps below. The maps also show the corresponding sea surface temperature (SST, °C) superimposed on the regional bathymetry (in meters). The location of the Deepwater Horizon is denoted by a star. Dates of each mission and the corresponding temperature sections can be viewed below. Also, comparisons between observed temperature sections and profiles with outputs from the Intra-Americas Sea Ocean Nowcast/Forecast System (IASNFS) dataset are available.
The AXBT data used in this site can be accessed via ftp.
These products provide information about the large scale circulation in the Gulf of Mexico. They describe the surface temperature as well as the structure of oceanic thermal features at different depths. They also provide information about ocean heat content and can be used in the validation of numerical models currently being utilized in the Gulf of Mexico monitoring.
