I have written all the ADCP data to ascii files. There are 20 files in all, adp02.asc through adp21.asc. The files could all be appended together to give a single file for the whole cruise, but it is more sensible to break them at sensible points in the cruise track. The first few lines of one of them looks like this: ymd hour lat lon depth absve absvn ve vn vvel errvel ampl pcgood YYYYMMDD HHMMSS degrees degrees m cm/s cm/s cm/s cm/s cm/s cm/s percen 19990107 225605 -30.16394 66.50943 15.0 -593.61 452.90 0.00 0.00 -4.10 5.60 179.0 100.0 19990107 225605 -30.16394 66.50943 23.0 -589.70 460.49 0.00 0.00 2.50 2.30 161.0 100.0 19990107 225605 -30.16394 66.50943 31.0 -597.63 452.92 0.00 0.00 4.00 4.70 162.0 100.0 The first 2 variables are time, absve/n are the absolute current velocities at the depth given, ve and vn are the ships absolute velocity (not sure why they are exactly zero for the first couple of profiles. I cant remember whether ve and vn are the velocity of the ship over the ground or the velocity of the ground relative to the ship - easy to check this of course! vvel is vertical velocity calculated by the adcp (dont believe it), errvel is an error calculation, ampl is the amplitude of the backscatter and pcgood is 0-100 percent good returns (OK usually if over 25%). There are 60 rows for each lat/lon/ve/vn value, at depths of 15(8)487m There is a set of 60 such rows every 2 minutes. In total there are 20 files, each 5-10Mbytes long, total of nearly 200 Mbyte (megabyte = megaoctet in French I think) I have given time to the second and lat/lon to 5 decimal places (1 m) to aid the exact alignment of the ADCP and CTD data in time or position.
