Hydrospatial and the Marine Environment

Hydrographic offices (HOs) today exist in a world of accelerating technological change that is influencing human behaviour and creating new needs and ways of exploiting data to understand our world. H...

The Marine 2020s: Three Ambitious Global Projects

The Marine 2020s: Three Ambitious Global Projects

“In all beginnings dwells a magic force …”. Hermann Hesse’s famous verse seems to be particularly relevant to the coming decade when it comes to marine activities. Three ambitious global proje...

State of the Art in Multibeam Echosounders

State of the Art in Multibeam Echosounders

Although the single beam echosounder is still in use, it has over the last 25 years gradually been replaced with new and less expensive multibeam echosounder (MBES) systems. And, although some side-sc...

What Is ‘Hydrospatial’?

What Is ‘Hydrospatial’?

Measuring and 3D Mapping of Sea Ice in the Arctic

How can AUVs be reliably used to map the 3D structure of the underside of sea ice? Especially now that the climate crisis makes it more important than ever to understand its complex structure? Sea ice...

Automatic Calibration for MBES Offsets

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, su...
