Integrating the continuous hydrographic datum and DEM for maritime boundary delimitation
The delimitation of maritime boundaries plays a significant role in preserving a country’s sovereignty and jurisdiction. Their determination justify a country’s rights, allowing coastal states to ...
GeoAI in the marine domain
GeoAI is the application of artificial intelligence (AI) fused with geospatial data, science and technology to solve geographic-based problem sets. GeoAI, therefore, is not a product to be bought and ...
Beyond either/or: integrating hydrographic technologies for a data-driven future
For too long, discussions about hydrographic surveying methods have centered on comparing individual technologies – multibeam vs. Lidar, Lidar vs. satellite, satellite vs. multibeam. This ‘either/...
Power to AI? Power to the people!
The rise of artificial intelligence (AI) solutions, especially in the offshore industry, does not mean our work is done. The key question is not whether AI can replace us, but how we can leverage it ...
S-100 sea trials in the St Lawrence River
Following the adoption of the new ECDIS performance standard at IMO MSC106 in November 2022, the International Hydrographic Organization (IHO) has planned a phased rollout of S-100 navigational inform...
Making subsea history by locating Endurance
In March 2022, almost precisely 100 years after the burial of famed British polar explorer Ernest Shackleton, his legendary ship Endurance was finally located at the bottom of the Weddell Sea in Antar...
Autonomous bathymetric survey in the UK Atlantic
Ensuring safe and efficient maritime navigation is a critical task for coastal nations, but can also be a lengthy and costly exercise. The UK Hydrographic Office (UKHO) is responsible for charting mil...
Surveying Lake Titicaca
In October 2024, officers from the Category “A” Specialization Programme in Hydrography for Naval Officers of the Peruvian Navy conducted their complex multidisciplinary field project at Lake Titi...
Seabed 2030’s invaluable journey
In 2017, when the Nippon Foundation-GEBCO Seabed 2030 Project began, only 6% of the global ocean floor had been mapped to modern standards. By World Hydrography Day 2024, that figure had risen to 26.1...
Hydrographic data a crucial factor in the success of D-Day and beyond
In 2025, the world will mark 80 years since the end of World War II – a conflict defined by pivotal moments such as the Normandy invasion. Known as D-Day, this extraordinary operation saw 156,000 Al...
Charting depths from above with airborne bathymetric Lidar
The mapping of underwater terrain and the monitoring of coastal and inland waters have been transformed by airborne bathymetric Lidar. The precision of laser-based remote sensing, combined with the ab...
AI-based automatic detection technology for rip currents
To support the prevention of casualties from rip currents, the Korea Hydrographic and Oceanographic Agency (KHOA) applied object detection and image classification technologies to real-time rip curren...
Skills and tech: hydrography’s balancing act
Each year, Hydro International picks up the sounding line to gauge the landscape of the hydrographic sector. By posing questions to the hydrographic community, we measure the currents and underlying t...
Promising future for hydrography
The hydrography profession seems to have a lower profile among young people compared to other marine sciences. Enrolment in hydrography courses has been decreasing for many years, and companies are st...
