Latest articles on the theme of Hydrographic Data Acquisition & Processing

The Netherlands Begins Archaeological Survey on Former Zuiderzee

The Netherlands is a maritime nation, evidence of which can still be found in waters throughout the country. Even so, only a small part of these waters has been surveyed, and it is very likely that there are many more shipwrecks, submerged... (read more)

Open Source Software and Hydrographic Survey Data

Hydrographers and data processors are expected to produce high-quality deliverables with a swift turnaround in this present age of data collection and technological refinement. However, the cost of proprietary commercial software processing... (read more)

Reference Area for Multibeam Bathymetry and Backscatter

Hydrographic measurements are nowadays usually carried out using multibeam echosounders (MBES). The measurements obtained by each operational hydrographic vessel need to be regularly controlled on a well-known area to validate the quality,... (read more)

Automatic Calibration for MBES Offsets

Currently, calibration of multibeam echosounders (MBES) for hydrographic surveys is based on the traditional ‘patch test’ method. This subjective method, although rigorous, has major drawbacks, such as being time-consuming (both... (read more)

A selection of articles for this theme by Wim van Wegen.

Sentinel-2 Coastal Charting Worldwide

It is widely and wrongly assumed that the world’s coastal regions have been surveyed in detail by modern techniques and that the resulting nautical charts are an accurate reflection of the nature of the seabed. This optimistic approac... (read more)

How Robotic Technology Officially Identified the World War II Submarine S-28 Gravesite

After 75 years, and using advanced imaging technology, ocean explorer Tim Taylor and his Lost 52 Expedition Team have officially discovered the final resting place of the 49 sailors of the US submarine S-28 (SS-133) off Oahu, Hawaii. T... (read more)

How the Seafloor of the Antarctic Ocean is Changing

Experts have reconstructed the depth of the Southern Ocean at key phases in the last 34 million years of the Antarctic’s climate history. The glacial history of the Antarctic is currently one of the most important topics in climate re... (read more)

EMODnet Bathymetry Now Offers Highest Resolved Bathymetric Worldwide Layout

Bathymetry, the topography of the seafloor, is a fundamental feature of the ocean. Accurate bathymetric data is the foundation for much of ocean science and policy. For example, nautical charts are based on these data to ensure safe ship na... (read more)
