Additional Documentation: XBT data may be found on the cruise data CD. Due to a defect in the SeaBeam, software, which causes a loss of bottom detection when sea surface sound, velocities of less than 1500 m/sec are used, the data was all obtained with a, set sea surface sound velocity of 1500 m/sec on August 19, 22, 23, 29 and, September 2, 1999.
