Latest articles on the theme of Hydrographic Data Acquisition & Processing
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 s...
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...
Denmark has challenging seascapes to map and chart. It has a rich history of nautical charting that dates back to the seventeenth century, and many of its navigational products for...
High-resolution bathymetric surveys support aquaculture research and increase navigational safety. In a case study, Tim Webster reports how this is done at Cape John Peninsula in C...
Hydrographic measurements are nowadays usually carried out using multibeam echosounders (MBES). The measurements obtained by each operational hydrographic vessel need to be regular...
While nautical charting mainly focuses on bathymetry and objects that form a hazard to shipping, offshore construction and dredging require sub-bottom information. There is nothing...
Teledyne CARIS, a Teledyne Technologies company, has announced significant funding from Canada’s Ocean Supercluster award to develop software for remote operations survey pro...
A selection of articles for this theme by Wim van Wegen.
Surveying the seabed is still an enormous task. So far, only 20% of the regions under water have been mapped with echosounders. This refers only to the topography, not to the conte...
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...
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. How...
Currently, calibration of multibeam echosounders (MBES) for hydrographic surveys is based on the traditional ‘patch test’ method. This subjective method, although rigor...
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 ref...
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, na...
New research led by the National Oceanography Centre (NOC) has discovered how fast-moving waterfalls under the sea control the shape and behaviour of submarine channels. These unde...
