IHO File No S3/2644/A CIRCULAR LETTER 34/2019 3 July 2019 CALL FOR THE APPROVAL OF NEW EDITION 4.2.0 OF PUBLICATION B-6 “STANDARDIZATION OF UNDERSEA FEATURE NAMES” References: A. IHO CL 67/2013 dated 21 November – Publication B-6, New Edition 4.1.0. B. 11th Meeting of the Inter-Regional Coordination Committee - Doc. IRCC11-07I2 and Draft List of Decisions (Doc. IRCC11-16B). C. IHO CL 20/2019 dated 28 March - The IHO Online Form System for Responses to Circular Letters and Input to IHO Publications (P-5 and C-55). Dear Hydrographer, 1. Edition 4.1.0 of Publication B-6 – Standardization of Undersea Feature Names – was published in 2013 (Reference A) and then slightly updated in 2017 to take account of the change from International Hydrographic Bureau to IHO Secretariat in accordance with the revised IHO Convention. 2. The need to update this publication arose several times at the recent Sub-Committee on Undersea Feature Names (SCUFN) meetings with the goal to improve the guidelines used by proposers in their preparation of naming proposals; and subsequently the efficiency of the reviewing work by SCUFN Members. Reports and proposals from SCUFN Members and ad hoc sub-groups have resulted in a number of improvements and additions to B-6. 3. The following changes have been made in the proposed new Edition 4.2.0 of B-6:  The list of national authorities (pp. 2-7 and 2-8 in the current Edition) has been removed. It has been updated and is now available on the SCUFN page of the IHO website > Miscellaneous > Lists of…Naming Authorities. This will allow the maintenance of this list to be facilitated.  References to the GEBCO website (www.gebco.net) and to www.scufnterm.org, listing all B-6 terms and definitions, and operated by the Korean Hydrographic and Oceanographic Agency (KHOA), have been inserted.  Preference for names in relation with marine research, as choice for specific terms, has been emphasized.  Additional guidance in paragraph II.A.6 depicting the way of grouping specific (term) categories of features has been included.  Provision of naming proposals in digital form and feature geometries as shape files are recommended in the proposal form.  Additional guidance on the use of generic terms as recommended by SCUFN only (not obsolete terms) has been included.  Definitions of some generic terms, such as Peak or Pinnacle, have been improved.  Additional generic terms with genetic implication, such as Reef or Shoal, have been identified and marked.   A number of historical generic terms, such as Cap, Discordance, Ground, Pass, Plain, Re-entrant or Seabight, sometimes appearing in the current GEBCO Gazetteer1, have been included with their definitions in the list of generic terms used for harmonization with other gazetteers (not to be used in new proposals).  The Users’ Guide for Preparation of Name Proposals (Appendix A) has been improved, for example by inviting proposers to provide feature geometries as shape files; release and handover their supporting bathymetric data to the IHO DCDB; and provide better informed supporting bathymetric maps.  A Fast-Track Procedure for the adoption by SCUFN of names proposed by national geographical naming authorities has been added as new Appendix B. 4. This proposed new Edition 4.2.0 was prepared and approved by SCUFN Members, endorsed by GEBCO Guiding Committee (GGC) at its 35th meeting in November 2018, as well as by IRCC at its 11th meeting in June (Reference B, Decision IRCC11/29 refers). Red-line and clean versions of the proposed new Edition 4.2.0, as endorsed by the IRCC2, are available at: www.iho.int > Standards & Publications > Draft Publications Awaiting Approval by Member States > B-6 Edition 4.2.0. 5.
