OPNAVINST S5513.5
A unclassified. This includes, but is not limited to, sounding records, echograms,
collection sheets, small scale chartlets prepared for inclusion in scientific or technical
papers, and similar sounding information where the method of positioning is by
conventional navigational means such as piloting, navigation radar, celestial, loran, or
dead reckoning.
(10) Sounding information, as well as visual observations, and sonar contact, indicating
uncharted features which are dangers to navigation shall be unclassified. Reports of
such features shall be sent to the Defense Mapping Agency Hydrographic Center by
message and verified by mail. The verifying correspondence shall contain recorded
soundings, plotted ship tracks, and any additional information that will assist in
positioning and evaluating the danger. The necessity of security classification for
such correspondence will be determined IAW the preceding criteria.
(11) Sounding information obtained incident to off-shore surveys conducted for the
purpose of improving standard navigational charts is normally unclassified although
conducted under precise electronic control.
B.
The guidance of paragraph 07A. concerning classification of bathymetry permits the use of
sanitized survey data:
(1)
In unclassified charts when such information is restricted to specific contour lines of
small areas which delineate potential navigational hazards to surface ships or
submarines. The Oceanographer of the Navy is hereby delegated the authority to
determine the extent of sanitization required in such instances.
(2)
In unclassified scientific studies when such information is limited to selected areas of
particular scientific interest where one would normally expect highly detailed
oceanographic surveys to be conducted, the Oceanographer of the Navy is responsible
for coordinating the review of classified survey data by appropriately cleared
members of the nations's scientific community and for subsequent submission of
requests to the Chief of Naval Operations (OP-096DX) for declassification of survey
data in-specific areas.
