 Processing comments Dennis McGillicuddy, Harvard University

 It is our experience that the actual drop rate of T-7 XBTs is about 6
 percent faster than accounted for by the Sippican drop rate equation.
 We therefore applied a uniform stretch to each profile of 1.065.
 Intercomparison of an XBT profile (station 10) with the nearest CTD
 station showed similar structure but substantial offset (1.2
 degrees)." A 1.2 degree adjustment (added) has been applied to each XBT.

Supplied Description:

Instrument Type

Generic Name: Expendable Bathythermograph

Acronym: XBT

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/132/

Generic Description:

An XBT is an expendable free-fall temperature probe that provides a profile of measured temperature against depth calculated from a fall-rate model. For example, two popular XBT models are the T-5 and T-7 probes from Sippican. More information is available from Lockheed Martin Sippican at URL: http://www.sippican.com/.
