Files of the form update.O.DATASET.gz or update.S.DATASET.gz, contain all major updates for the named dataset since the release of WOD09.
Refer to WOD09 documentation for additional details. Refer to instructions
on downloading and reading WOD09 data.
A major update is a change to position (latitude/longitude),
date (year, month, day, (not GMT time), or depth/measured variable. Major updates are made in the course of continuing quality control
of the data and communication with the submittor of the data.
User can get all updates for specific dataset (i.e., update.O.OSD) or updates for a particular month (i.e.,
update.O.OSDJan2008) under each date stamped link.
A time stamp has been added to any cast which is part of an updated file. The time stamp is found under second header #99,
and is of the form [4digit year][julian year day] (ex. 2008001 means the cast was last updated January, 2008).
