Surveyors Map Sunken Liberty Ship off Texas Coast

U.S.-based marine data acquisition services company TDI-Brooks said it recently mapped the Liberty Ship George Vancouver off Freeport, Texas while out on a seabed survey project with the R/V Brooks McCall. The multiple multi-phase geophysical and geotechnical site surveys program consisted of pipeline routing and subsea structures to facilitate route and project design for offshore developers.Equipment used to map the ship was a Teledyne Reson SeaBat T-20 multibeam sonar with integrated Applanix POSMV for Motion. Applying the mesh tools to the multibeam survey shows an example of the shipwreck.Texas

When using dense, high-precision survey data, the method for management and visualization of the data can have a large impact on the final decision making process. This is an important factor when accurate shape reconstruction is required, as there are significant trade-offs with traditional approaches. For applications where it is critical to know exactly the shape and size of surveyed objects, a high-resolution 3D mesh is likely the best option.Gridded surfaces, even with variable resolution, cannot adequately model complex overlapping or vertical structures.

Researchers Use AI to Map Marine Environments

Researchers at the University of Bath have developed an AI model that can automatically classify underwater environments directly from sonar measurements.Sonar is commonly used to map the ocean floor, and seabed composition (e.g. mud, clay or rock) affects the way the sound is reflected back. Salinity, depth and water temperature also affect how sound waves are propagated through water. This means that sonar measurements at different depths and distances can give accurate soundings of the ocean’s properties, for example how underwater currents propagate, how the deeper ocean changes with the
