The *OFFICIAL* (:^]) definition of day-of-year, as used by NASA and
as outlined
 in the ISO-8601 standard, begins with January 1st as DOY=001.

Aha!   That may explain why some oceanographers (satellite-kind) 
use JAN 1st as DOY 001 and other oceanographers (dipnet-kind) prefer JAN
1st as DOY 000.
 Thanks for the info.
