Floats 302 thru 340 store more than one value of Temperature and Pressure per day.
"none" in the sound-velocity column means that no acoustic tracking was done;
positions were interpolated between launch and surface locations.
Floats launched in 1996 and 1997 were hard to track because they stopped transmitting
after just a few days.  The floats launched in 1998 were hard to track because 
there were few sources available to them.
*Floats 371 and 374 used 1500 as the sound velocity for source 197.
