XBT
(bathythermograph)
Other
An expendable bathythermograph is a specialized device used
to collect a temperature profile at varying depths. The
information is used to find thermoclines, ocean fronts or
current eddies that will indicate the presence of fish especially
tuna. Vessels may have automated or manually operated
XBTs. If an XBT is used by the vessel, a probe may be
deployed regularly.
Complete for other devices as necessary.
