Hydrographic Data Acquisition & Processing Weeks

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)

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)

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)

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)

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)

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)

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)

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)
