NEW YORK, 21 November (Division for Ocean Affairs and the Law of the Sea) ― The Commission on the Limits of the Continental Shelf held its sixty-fifth session at Headquarters, from 20 October to 21 November.
The session was devoted to the scientific and technical examination of submissions at the geographic information systems laboratories and other technical facilities of the Division. No plenary meetings were held during the session. Members of the Commission also participated in internal exchanges of views on general scientific, technical and other relevant topics.
Ten submissions, namely the submissions made by Palau (North Area); Portugal; Spain (Galicia); Namibia; Mozambique; Mexico (eastern polygon in the Gulf of Mexico); United Republic of Tanzania; and Denmark (Southern Greenland); as well as revised submissions made by Brazil (Brazilian Oriental and Meridional Margin) and the Russian Federation (Gakkel Ridge in the Arctic Ocean), were considered by the respective subcommissions.
The subcommissions also met with the delegations of Brazil, Denmark, Mexico, Mozambique, Namibia, Portugal, Russian Federation, Spain and the United Republic of Tanzania.
Underscoring the importance that submitting States attach to the work of the Commission, delegations were represented at the high level: the delegation of the Russian Federation was headed by the Minister for Natural Resources and Environment, Alexander Kozlov.
In 2026, the Commission is scheduled to hold the following three sessions, subject to the approval of the General Assembly: the sixty-sixth session from 9 February to 13 March 2026, with plenary parts to be held from 9 to 13 February 2026 and from 2 to 6 March 2026; the sixty-seventh session from 6 July to 7 August 2026, with plenary parts to be held from 6 to 10 July 2026 and from 27 to 31 July 2026; and the sixty-eighth session from 19 October to 20 November 2026, without plenary parts.

Background
Established pursuant to article 2 of annex II to the 1982 United Nations Convention on the Law of the Sea, the Commission makes recommendations to coastal States on matters related to the establishment of the outer limits of their continental shelf beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured, based on information submitted by those coastal States. The recommendations are based on the scientific data and other material provided by coastal States in relation to the implementation of article 76 of the Convention and do not prejudice matters relating to the delimitation of boundaries between States with opposite or adjacent coasts or prejudice the position of States that are parties to a land or maritime dispute, or application of other parts of the Convention or any other treaties. The limits of the continental shelf established by a coastal State on the basis of the recommendations are final and binding. In the case of disagreement by a coastal State with the recommendations of the Commission, the coastal State shall, within a reasonable time, make a revised or new submission to the Commission.
Under rule 23 of its rules of procedure (Public and private meetings), the meetings of the Commission, its subcommissions and subsidiary bodies are held in private, unless the Commission decides otherwise.
As required under the rules of procedure of the Commission, the executive summaries of all the submissions, including all charts and coordinates, have been made public by the Secretary-General through continental shelf notifications circulated to Member States of the United Nations, as well as States Parties to the Convention. The executive summaries are available on the Division’s website at: www.un.org/depts/los/clcs_new/clcs_home.htm. The summaries of recommendations adopted by the Commission are also available on the above-referenced website.
The Commission is a body of 21 experts in the field of geology, geophysics or hydrography serving in their personal capacities. Members of the Commission are elected for a term of five years by the Meeting of States Parties to the Convention having due regard to the need to ensure equitable geographical representation. Not fewer than three members shall be elected from each geographical region.
Currently, one seat on the Commission continues to be vacant owing to a lack of nominations from the Group of Eastern European States.
The Convention provides that the State Party which submitted the nomination of a member of the Commission shall defray the expenses of that member while in performance of Commission duties. A voluntary trust fund for the purpose of defraying the cost of participation of the members of the Commission from developing countries has been established. It has facilitated the participation of several members of the Commission from developing countries in the sessions of the Commission.
The convening by the Secretary-General of the sessions of the Commission, with full conference services, including documentation, for the plenary parts of these sessions, is subject to approval by the General Assembly of the United Nations. The Assembly does so in its annual resolutions on oceans and the law of the sea, which also address other matters relevant to the work of the Commission and the conditions of service of its members.
