This web site was created to provide easy access to eXpendable BathyThermographs (XBTs) data, XBT-derived products, and other XBT-related scientific and operational information; and to also bring together scientists to highlight the uses of XBT data including upper ocean thermal structure and variability, and ocean current transport.

This site is hosted at NOAA/AOML and contains input from the XBT Science Team members.


The 4th XBT Workshop: XBT Science and the Way Forward

The 4th XBT Workshop will bring together scientists working on XBT data to discuss recent advances in assessing XBT biases and their impact in ocean heat content studies. The main expected outcome of the meeting is to reach a consensus on recommending a unique XBT bias correction to the global XBT data set.
