Science and Technology Board propels US Navy towards a hybrid fleet
The navy-after-next will be a ‘hybrid fleet.’ This concept was first articulated by then-Chief of Naval Operations (CNO) Admiral Michael Gilday and embraced by his successor, Admiral Lisa Franchet...
Mapping the largest known cold-water coral reef habitat
More than a decade of mapping and exploration work by federal, academic and private-sector partners has uncovered what has been deemed the largest deep-sea coral reef habitat mapped to date. Spanning ...
Highs and lows: surveying at different altitudes
The term ‘digital twin’ has gained significant popularity in recent years, becoming a buzzword in various industries, particularly in the context of emerging technologies and innovations. Hypes co...
Sound speed or sound velocity profiling: which is technically correct?
Hydrographer and researcher Elias Adediran unpacks a common misconception in hydrography: is it really ‘sound velocity profiling’ or should we be saying ‘sound speed profiling’? Drawing on ind...
How I accidentally became a multibeam trainer
When Jonathan Beaudoin delivered his first multibeam training session, it wasn’t part of some grand plan – it started with a phone call and a willingness to say yes. Two years and more than 50 cou...
Canada’s pioneering role in hydrography
Manon Larocque oversees hydrographic efforts across one of the most geographically vast and diverse maritime regions in the world. Here, she shares her perspective on Canada’s influential role in th...
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 ...
Robotic intelligence for subsea cable inspection
Everyday life around the world depends on a global network of over 500 subsea cables that silently carry 95% of all international data [1]. These cables stretch more than 1.4 million kilometres across...
Airborne Lidar and photogrammetric accuracy
Many surveying professionals – and contract specifications – use the term ‘accuracy’ without fully defining it, according to our technical editor Huibert-Jan Lekkerkerk. Using the ASPRS and IH...
The Silicon Valley of smart ocean technologies
Underwater acoustic technology has been part of the hydrospatial industry’s toolbox for many decades, but as we witness throughout our industry, the combination of increasingly capable computing pow...
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...
