Notes:
1. re VCM 164: One blade broke off while attempting deployment on 970210.
   VCM was brought back aboard.  Blade was swapped with one from VCM 165
   blade set.  Size was too close to differentiate, so deemed acceptable.
   Subsequent deployment on 970211 went well.  (One VCM165 blade set was
   damaged on setup and not deployed, making available its remaining blade
   sets.)
2. Not heard until 980312.
3. Not heard.

VCM (Vertical Current Meter) floats have horizontal propeller blades
which cause them to rotate in vertical flow.  The rotation information
is collected along with temperature, pressure and salinity.

The floats with numbers greater than 1000 were SOLO (Sounding Oceano-
graphic Lagrangian Observer) VCMs, a second-generation ALACE, with 
seawater pumps to improve flushing times and a more-reliable buoyancy
engine.

The trajectories consist of a sinking point and a surfacing point, 
extrapolated from the surface Argos locations using objective inter-
polation.  Since the floats can ground themselves, the set of posi-
tions was searched for instances where the ocean depth at the float 
position was possibly as shallow as the float depth. If bottom con-
tact was suspected, the record was marked.
