IHO releases new standards for hydrographic surveys

The IHO released earlier this month a new edition of the Standards for Hydrographic surveys (S-44). In addition to surveys to support the safety of navigation, these standards can be adapted for oil and gas, renewable energies, dredging, geophysics, and geotechnics.

Mapping the Future: Fiji Hosts Pivotal Meetings on Ocean Mapping and Hydrography

Suva & Nadi, Fiji — November 2024 Fiji became the epicenter of global ocean mapping, hydrographic collaboration and geospatial information management as it hosted a series of landmark meetings with a strong focus on Pacific engagement. From the 41st Meeting of the GEBCO Guiding Committee (GGC41) and the 6th Pacific Ocean Mapping Meeting to the subsequent UN workshops on geospatial frameworks and sustainable development, the events underscored the critical role of ocean and data governance for Pacific Island countries and territories.

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.

The IHO discusses Ocean Mapping at the IOC UNESCO Executive Council Meeting

Using hydrography to adapt to a changing ocean

The marine environment is constantly changing, whether due to variations in the climate, extreme environmental events, or simply the natural movement of tides and currents. Up-to-date hydrographic information enables countries to measure and adapt to these changes.
