the cruise track is produced by running the m-file cruise_track.m    it
is presently set to plot just the whoi and sio mooring positions from
both years, but options inside cruise_track include plotting drifter and
float release positions. sogbasemap.m makes the base map with just coast
and 1000 m isobath. you need to set at the front of cruise_track the x,y
limits of the basemap. the other files supply data needed by
cruise_track and sogbasemap.
