UNCLOS and the international legal framework suitability for ocean activities discussed at ABLOS Conference
The 12th IHO-IAG ABLOS conference brought together participants from all over the world to discuss how the global regulatory framework and the United Nations Convention on the Law of the Sea (UNCLOS) addresses some of today's most pressing ocean-related challenges. Organised in partnership with the Qatari Standing Committee of the Convention on the Law of the Sea, the 280 participants learned about achievements of UNCLOS, challenges it faces in today’s international context, and gaps to be addressed. One question which emerged repeatedly was whether the convention was flexible enough to address modern issues.
EU Coastal Nation Joins the IHO
Lithuania has officially joined the International Hydrographic Organization (IHO), becoming its 103rd Member State and marking a historic milestone as now all EU coastal nations are part of this global organization.
Smart Navigation Moves Closer to Reality: Completion of Phase 1 of the S-100 Implementation
With the operational release of standards S-124 Navigational Warnings and S-128 Catalogue of Nautical Products, Phase 1 of S-100 Standards implementation has now been completed, marking a major step in the modernisation of navigation.
Products and services using these specifications can be updated in near real-time, directly supporting the enhancement of navigational safety and facilitating on-board data management. Data services conforming to these standards are now ready for production and integration into navigation systems such as the S-100 ECDIS.

The Gambia Joins the IHO: Strengthening Hydrographic Capacity in West Africa
The International Hydrographic Organization (IHO) proudly welcomes the Republic of The Gambia as its newest Member State, marking a significant milestone for both the Organization and the West African region. With this accession, the global hydrographic community continues to grow in Africa, underscoring the increasing recognition of the importance of hydrography for safe navigation but also coastal zone management, tourism, UNCLOS obligations and more.
Major Milestone Achieved in Transition to Smart Navigation with Operational Editions of S-100 Standards
In a historic breakthrough for digital navigation, the International Hydrographic Organization (IHO) Member States have adopted the first set of operational standards within the S-100 framework. This decision paves the way for Coastal States to offer official products and services based on these standards, significantly advancing the field of maritime navigation. The adoption also has profound implications for ocean data collection and sea surveys, as these new products will require enhanced data in order to realize their full potential.
