Enhanced Solutions for Seagrass Monitoring
A new, non-invasive method to measure and monitor seagrass biomass on the seabed around England’s southwest coast has been successfully demonstrated this year as part of a collaborative project supp...
These theme weeks take us to the very core of our industry. The nautical chart – the original driver of hydrography – is still going strong and, be it in paper form or ENC, is used on every ship. To create these, extensive bathymetric surveys are performed and additional data is collected on aids to navigation and topography. However, it is not only the nautical chart that requires bathymetric data: this is and will continue to be the backbone of hydrographic surveying employing echosounders, side-scan sonar and advanced positioning systems.

Since the 1970s, remote sensing has increasingly been used to conduct underwater surveys. Several methodologies are employed in hydrographic surveying, from direct techniques such as probing rods to m...
Unique Group has successfully supported the Australian Institute of Marine Science in completing a carbon-conscious bathymetric survey at Cape Ferguson by performing seabed modelling for their upcomin...
The UK Hydrographic Office (UKHO) has started supplying bathymetric survey data for non-UK waters to the General Bathymetric Chart of the Oceans (GEBCO), after signing the memorandum of understanding ...
The British Geological Survey (BGS) has released a new fine-scale digital map featuring the seabed geology of offshore Anglesey. The island (in Welsh known as Ynys Môn) follows the Bristol Channel ...
To understand coastal change and anticipate what our future coast will look like, scientists carry out regular field surveys in the form of beach profiles and digital elevation models (DEMs). Until no...
When students of the Stockholm University course in Marine Geophysical Mapping Methods collect sediment cores from the bottom of the Baltic Sea, the cores are immediately used in research. No sample m...
We asked five experts for their views on the trends and developments in bathymetric data, as this is and will continue to be the backbone of hydrographic surveying with echosounders, sidescan sonar an...
Manually examining the seafloor for objects such as wrecks requires a great deal of time and labour, both at sea and in the office. As time is a limited and costly factor, the industry is constantly s...
Aside from being able to monitor water depths, the most recent multibeam echosounder sonar (MBES) systems can also simultaneously record the reflected intensities from different seafloor surfaces. Wit...
