For generations, hydrographers explored the oceans with a lead-line and a chart that was mostly empty white space. Over the past hundred years, however, ocean mapping has leapt from hand-cast sounding...

Recent research demonstrates that multibeam echosounder (MBES) water column data deserves closer attention from the hydrographic community, particularly for the remote estimation of underwater gas emi...

Hydrography has long been defined by depth. From nautical charting to navigation safety, bathymetry remains the primary deliverable. But many blue economy activities – offshore wind, subsea cables, ...

In order to ensure safe navigation, Flemish Hydrography (FH) uses multibeam echosounders to precisely determine the depth and shape of shipwrecks. After a detailed survey and processing of the data, r...

Thanks to major advances in both the technological methods used and the richness of the datasets available on the condition of wind farms, it is becoming easier for developers and operators to look be...

The shallow nearshore coastal zone plays a critical role in coastal erosion processes, flood risk and ecosystem dynamics, yet it is one of the most difficult environments to survey. This article exami...

Getting away from the daily grind can be the perfect way to not only recharge one’s batteries, but also to rediscover one’s passion and appreciation for hydrography. After weeks of seemingly non-s...

As NIOZ Royal Netherlands Institute for Sea Research prepares to bring its new flagship research vessel Anna Weber–van Bosse into service, attention is shifting from construction to capability. Duri...

The maritime sector is entering what is often called the S-100 era. Much of the discussion so far has focused on compliance timelines and new product specifications. However, the deeper importance of...

To protect New Zealand’s coastline, Toitū Te Whenua Land Information New Zealand (LINZ) has launched the 3D Coastal Mapping Programme. Over three years, this technically demanding initiative will c...

In September 2025, Brazil reached a historic milestone in the modernization of nautical cartography with the conclusion of its first electronic navigational chart (ENC) produced under the internationa...

Hydro International presents this overview of the four candidates who are nominated for the posts of secretary general and/or director at the IHO Bureau in Monaco. During the next IHO Assembly in Mona...

Hydrographers are swimming in a vast ocean of data. Whether from ENC databases, weather satellites, buoys monitoring ocean conditions or sonar pings from the latest bathymetric survey, data is constan...

With a rapidly growing international membership base, the Ocean Autonomy Cluster (OAC) based in Trondheim, Norway, is supporting cross-border collaboration and innovation around the world. In this int...
