	A125L24 was a "cheap beam" cruise by Dan Fornari on the East Pacific
Rise. They logged no course and speed data or satnav or satfix data. The GPS
they logged is quite 'shakey' at times, and without course and speed data it
would take an very long time to try to fabricate them and they would still be
doubious at best. The SeaBeam files are very small and appear to be for ALVIN
dive-site positioning. There are five averaged files under PPROCESS.AVGCB that 
may be of some significance, but on these 'cheap beam' cruises we get no 
cruise reports, these files are quite but may cover an area of interest to 
someone.
	 I am sending the 'raw' SeaBeam and GPS data to you in the off
chance that someone may want to see these data despite the fact they are poorly
navigated.
