TDI-Brooks Maps the Liberty Ship Reef Site George Vancouver

TDI-Brooks recently mapped the Liberty Ship George Vancouver Reef off Freeport, Texas while out on a seabed survey project with the RV 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 has been involved in artificial reef development for nearly 50 years. Numerous reef building materials have...

German U-boat Surveyed a Century after Wartime Sinking

A First World War German submarine has been surveyed for the first time since its loss in 1917. Sophisticated scanning techniques and deep-sea video footage have revealed a large hole in the boat's hull – caused by an attacking British naval vessel. During the summer of 2020, scientists led by deep sea archaeological expert Dr Rodrigo Pacheco-Ruiz of the University of Southampton, in collaboration with offshore survey companies MMT and Reach Subsea, investigated the wreck of UC-47 on behalf of Tolmount Development during offshore operations to prepare for the laying of a new pipeline in the North Sea, some 20...

EvoLogics Modems Now Authorized for US Navy Use

EvoLogics underwater acoustic modems were recently listed as Authorized for Navy Use (ANU), following a lengthy period of testing and technical evaluation by Naval Sea Systems Command (NAVSEA) and the Emergency Ship Salvage Material (ESSM) system. The ANU programme provides a list of selected diving equipment, tools and accessories that have undergone design safety reviews, testing and evaluation to ensure diver safety and acceptability. Engineers at ESSM who conducted the testing of the EvoLogics 18/34 kHz USBL modem system concluded “the system to be more accurate than our ability to physically measure the angle and distances between the USBL and...

Combined Mexican and Spanish Search Expedition for Sunken Galleon

Researchers from Mexico’s National Institute of Anthropology and History and Spain’s National Museum of Underwater Archaeology will try to find the wreckage of a Spanish galleon which went down carrying gold, silver and precious gems worth billions. Both countries have agreed to join forces to search for the legendary Nuestra Señora del Juncal,  which sank in a storm nearly 400 years ago. It disappeared to the bottom of the ocean in October 1631 after setting sail with its fleet from Veracruz, on the east coast of Mexico, bound for Spain. Many sailors feared the galleon was already doomed as its commander died... (read more)

This Is How Airborne Multibeam Lidar Coastal Mapping in Paradise Is Done

Insights from the first commercial use of Fugro RAMMS
The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradisal Turks and Caicos Islands.
