The NODC provides shipboard ADCP data in two formats:

1) a high-density set (~10 Mbytes/month-long cruise)
in CODAS binary format consisting of currents and 
ancillary parameters at the sampling interval
with which the data were recorded and processed and 

2) an ASCII standard subset (~500 Kbytes per
cruise-month) of absolute currents at hourly and 
10 m intervals.  If absolute currents are not available 
due to lack of navigation, then relative currents are provided.
The standard subset includes the hourly means and standard 
deviations of ship velocity components and the transducer 
temperature.

     Also available in ASCII form are cruise tracks and cruise 
summary files which describe instrumentation, cruise 
activities and significant events, and the processing, 
calibration, and navigation steps.

     For requests of the high-density data set, please provide 
the type of machine on which the data will be loaded.  If the 
CODAS is compatible with the user's host machine, then the
CODAS block files, software, and extraction manual will be delivered.  
If CODAS has not been adapted yet for the user's machine, then an 
ASCII dump of the block files can be provided.
 
     Requests can be handled through electronic or paper mail.  
An anonymous ftp (kapau.soest.hawaii.edu, cd /pub/adcp)
account is available at the SAC for Internet users.  Questions, 
comments, data submissions, data requests, and CODAS software and 
manual requests should be directed to:
