Understanding sea-level rise - improving predictions through studying the shape of the seabed

In many places around the world, data clearly shows the level of the sea is rising. In low lying coastal areas, even small increases when coupled with high tides and storm surges have had devastating consequences, such as altering coastlines, impacting offshore energy infrastructure and displacing populations. A better understanding of factors influencing sea level is vital in order to prepare for and mitigate its impacts.

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.

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.

DCDB

In 1988, the U.S. National Geophysical Data Centre (NGDC) offered to host and operate a Worldwide digital oceanic bathymetry data center on behalf of the IHO Member States. This led to the official establishment (in June 1990) of the IHO Data Centre for Digital Bathymetry (DCDB). Data provided by the IHO Member States are available for download from the DCDB web site. It is possible to search, view or download all available data using the DCDB Web Map Server and GEODAS interfaces (please see below).

2nd UN Ocean Conference Lisbon

The Stockholm Environment Institute and the IHO are organizing a side-event on seabed mapping & marine data to support multifunctional spatial planning at the UN Ocean Conference in Lisbon. Organized in partnership with IOC-UNESCO, Sweden, the African Union Commission, and the United Kingdom, the event will look at the role of marine data to inform the competing needs of a broad range of ocean stakeholders. Participants will discuss activities, innovations and challenges, as well as technologies and monitoring systems. It will examine how improved data could inform the organization of the marine space to ensure a more sustainable use of ecosystems.
