2000-2002 JAMSTEC Compact Arctic Drifter (J-CAD)  BETA Version
          Deployed by Japan Marine Science and Technology Center (JAMSTEC)

JAMSTEC's J-CAD Buoys drift with the ice pack making a collection of navigational, 
atmospheric, and oceanographic measurements and reporting the data back via satellite. 
    
Each year's NPEO drifting buoy deployment includes one J-CAD Buoy
   - NPEO 2000  had J-CAD 1
   - NPEO 2001  had J-CAD 3
   - NPEO 2002  had J-CAD 4
   
   
Each J-CAD is contained in a separate directory, and documented by included HTML files.
