Data collected daily along the ship track in JGOFS format from ARSV Laurence M. Gould and RVIB Nathaniel B. Palmer cruises to the Southern Ocean from 2001-2003 as part of the Southern Ocean GLOBEC project.

<h3>Environmental and Navigational Data from the Ship's Monitoring Systems,<br />
Reported along the Ship's Track</h3>

<p>This along track (JGOFS) data set was obtained primarily by applying calibrations to raw data and decimating to whole minute intervals. Several fields are derived measurements from more than an single raw input. For example, Course Made Good (cmg) and Speed Over Ground (sog) are calculated from gyro and GPS inputs.</p>

<p>Cruises often used \"9.99\" or \"9999\" to indicate bad data. Those numbers were changed to 'nd'. Not all bad data were flagged in this way however. Users of these data are encouraged to read the Data Report (found at the Directory Level of this system under \"Inventory\" then under \"project/cruise id\", and then under \"data report\") in order to be aware of bad data points that are not indicated by \"9\"s and therefore remain in the dataset.</p>
