8/8/2018: Termination of U.S. Coast Guard rebroadcast of HYDROLANT and HYDROPAC information

As a courtesy to our audience, Maritime Commons will provide a daily compilation of nationally-relevant Federal Register Notices. To provide comments for the public record, follow the Federal Register link for each individual notice. Please note, the Coast Guard cannot respond to comments on these notices outside of the Federal Register.

The Coast Guard announced in the Federal Register that as of Aug. 30, 2018 it is ceasing the rebroadcast of HYDROLANT and HYDROPAC navigational warnings over High Frequency Simplex Teletype Over Radio service (HF SITOR). HYDROLANT warnings are navigational warnings categorized by their Atlantic Ocean location. HYDROPAC warnings are navigational warnings categorized by their Pacific Ocean/Pacific Rim location.

There is no requirement for the Coast Guard to rebroadcast this information, although the Coast Guard has been voluntarily doing so for a number of years, and doing so is duplicative of the National Geospatial-Intelligence Agency’s broadcast. The information will continue to be disseminated by the National Geospatial-Intelligence Agency.

For more information, view the Federal Register Notice, or contact Derrick Croinex, Coast Guard chief of Spectrum Management and Telecommunications Policy at 202-475-3551 or derrick.j.croinex@uscg.mil.
