submitted with the uncut XBT traces to the National Oceanographic Data Center (NODC),
Washington, DC 20235. When specialized oceanographic cruises are being conducted at

CLASSIFICATION OF XBT OBSERVATIONS AND MESSAGES. During certain
classified operations, release of oceanographic information may reveal involvement with
classified missions or give a classified position. In such cases, data (messages and logs) shall
be assigned the appropriate classification. Additionally, such XBT data shall be safeguarded
according to procedures outlined in reference (c). Facilities for handling classified XBT data
are not available at the NODC. Therefore, classified logs and annotated traces shall be sent
directly to the Fleet Numerical Oceanography Center, Monterey, CA 93943.
