USS Arizona & USS Utah

On 7 Dec 1941, the US Naval base, at Pearl Harbor, Hawai'i, was attacked from the air. Among the many vessels that were lost, the USS Arizona and USS Utah are now National Historic Landmarks, under the care of the National Park Service. Multibeam Sonar, LIDAR, and photogrammetry were used to survey the ships, monuments, and other historical structures. These data will be tied together to create a 3D visualization of the underwater and above-water structures; providing a valuable tool to allow the US Park Service to monitor degradation of the ships over time. The data will also be used to give park visitors a unique view of the ships.

The Sonic 2024 was used to survey most of the Arizona using a small vessel of opportunity. Due to very shallow water and the Memorial itself, a Sonic 2020 was mounted on an Unmanned Surface Vessel (USV) to survey the areas where the manned vessel could not survey. The USS Utah was surveyed solely with the Sonic 2024. R2Sonic's I2NS provided inertial navigation. QPS QINSy software was used for the multibeam data collection. Multibeam data were post processed in QINSy, Fledermaus, and HyPack. Applanix POSPac processing was also employed for PPK positioning. LIDAR was used to scan the above-water structures. Dive teams performed visual inspection and photographed the hull structures.

A big mahalo goes out to the following:
National Park Service for coordinating the activities;
Autodesk's Stategic Projects division for project management, tying all the data together, and underwater photogrammetry;
R2Sonic for the bathymetric survey and post processing the 2024 data;
Etrac for supplying bathymetric survey talent and post processing the 2020 data;
Deep Ocean Engineering for providing the USV for the 2020 survey;
Gilbane Building for providing land surveying and LIDAR;
U.S. Navy dive team and the U.S. Navy Public Affairs.

The U.S. Navy Public Affairs made a short video of the activities.

HMS Erebus

The discovery of HMS Erebus, one of Sir John Franklin's two lost ships, is a significant occasion for Fisheries and Oceans Canada as it showcases the important work of the Canadian Hydrographic Service (CHS) and the Canadian Coast Guard (CCG). Along with public and private partners, the Canadian Hydrographic Service and the Canadian Coast Guard conducted the 2014 Victoria Strait Expedition with a number of common objectives such as mapping Canada's Arctic seabed, promoting arctic research and searching for the lost ships of Sir John Franklin's 1845 voyage to find the Northwest Passage. The data collected from the Canadian Hydrographic Service's R2Sonic 2022 multibeam sonars was used to produce a three-dimensional model of HMS Erebus that was used by marine archeologists from Parks Canada to confirm the identification of the wreck. The multibeam data will continue to be used by archaeologists and researchers as they conduct further analyses of HMS Erebus. YouTube video. Wikipedia article.

CSL Kinglett and CSL Gannet - two 7-metre hydrographic launches each equipped with R2Sonic 2022 multibeam sonar, Applanix POSMV V5 position and orientation system, AML Oceanographic sound velocity sensors and utilizing Hypack/Hysweep for data collection. The survey was conducted using post processed kinematic positioning derived from Applanix POSPac MMS. Data processing and image rendering was completed using CARIS HIPS.

Normandy D-Day wrecks

2014 marks the 70th Anniversary of the Allied landings on the beaches of Normandy - better known as D-Day. The vast naval operation resulted in many vessels being sunk by mines, enemy fire or submarines. A large scale hydrographic survey was organised to map and document the state of those wrecks. R2Sonic's U.S. agent, Measutronics (Lakeland, FL), provided much of the equipment required for the survey, including their Sonic 2024. R2Sonic provided an UHR (700 kHz) upgrade to Measutronics' Sonic 2024. R2Sonic also provided survey personnel support to assist in setting up and getting the multibeam survey operations off to a good start. Hypack was used for data collection and presentation in the television documentaries.

The results of the survey are documented in the following television programmes and will be presented as a movie to the veterans and dignitaries at the D-Day Anniversary ceremony in France (06 June 2014):

US: NOVA (PBS) "D-Day's Sunken Secrets" 2 hours
UK: Channel 5 "D-Day's Sunken Secrets" 1 hour and very different from the NOVA programme of the same name
France: "Opération D-Day La cartographie des épaves du débarquement"
