Surveying Artificial Reefs with a SeaBat T51

Tue, 25 Jun 2024 10:50:59 GMT

Artificial reefs make a great playground to produce stunning data when passed over with a SeaBat T51 at 800 kHz. But aside from that they have a more meaningful purpose.

Artificial reefs allow for sea life to recover from a decline in habitat. These reefs act as a recruitment, growth and resting zone for fish species and other sea life.

Artificial reef structures come in all shapes and sizes; giving species places to hide, allowing to live off the seafloor from predatory species, or providing a substrate to grow on.

Reefs captured with the RESON SeaBat T51-R Multibeam echosounder

All the images of the artificial reefs are captured with a SeaBat T51 at 800 kHz. For your survey this gives you:

Improved decision making: The frequency flexible 700-800kHz sonar array for up to seven times water depth efficiency - this gives you an extreme resolution that captures all the details you need.
350-430kHz sonar operation for traditional and extended range survey requirements maximising your sonar usage
Hands-free: This model comes with Autonomous Sonar Controls – allowing the operator to focus on other tasks than controlling the sonar

Surveying the wreck of the HMS Hood (1891)

Tue, 23 Apr 2024 11:35:47 GMT

See how Teledyne Marine surveyed the wreck of HMS Hood with the Teledyne RESON SeaBat T51 800 kilo hertz multibeam echosounder.

In August 2023, Teledyne Marine set out to survey the wreck of HMS Hood (1891). The purpose of the survey was to document the status of the wreck with the latest in high resolution sonar technology.

The wreck is located at the entrance of Portland Harbour, Dorset, UK. HMS Hood was built in 1891 with an impressive length of 125 meters. In 1914, after 20 years of service, she was deliberately sunk to act as a “blockship,” to stop U-boats or torpedoes from entering the port.

Still faithfully resting at the harbour entry, the wreck of HMS Hood, once a popular dive spot, is deteriorating with age and it is understood, no longer safe to dive on.

By using the Teledyne RESON SeaBat T51 800 kilo hertz multibeam echosounder with the full swath and the smallest available receiver beamwidth, Teledyne Marine determined the status of the ship – delivering detailed, and accurate images of this largely forgotten piece of local naval history.

Combined Multibeam and LIDAR survay 2017

Tue, 13 Mar 2018 14:25:21 GMT

A video from a survey to monitor changes in a historical structure over time. The breakwater, which is between 200 and 300 years old and stretches for two kilometres, has suffered damage during storms many times over this period. Annual surveys will create a record of the structure as it currently stands and comparisons between datasets will enable detection of sub-centimetre movements over time.

The survey combines LIDAR and Multibeam scans to produce a single model of above and below water.

Difference models show

Erosion (scour) or deposition of sediment.
Displacement of rock armour
Subsidence of structures
Ross of material.

LiDAR scans were done above water with minimum possible water level to ensure maximum survey area coverage.

Laser Scanning of:

Rock armour revetments
Vertical masonry walls
Masonry and concrete paved areas
Slipway
Lighthouse

Multibeam scans were done below water level, at suitable tidal level to allow overlap of results with above water laser scan survey.

Sonar Scanning of:

Vertical walls,
Slipway,
Rock armour revetment,
seabed bathymetry and features.

The surveys were compared at all locations. The comparison has been done between the original survey (2015) and the current survey, using either:

Point Cloud comparison (distance Cloud to Cloud)
Mesh comparison (After modelling the point cloud into a surface),
Profile section across the seabed and the structures

Data images from the Multibeam Survey of the HMS Hampshire wreck site

Wed, 24 May 2017 10:45:55 GMT

Earlier this year Teledyne RESON was invited by Seatronics to assist with the mapping of HMS Hampshire.

HMS Hampshire sank on the 5th June 1916 when she struck a mine laid by German U-Boat U75. The wreck is located in approximately 60 meters of water off the west coast of Orkney and sank while en-route to Archangel in Russia. She was transporting Lord Kitchener, Secretary of State for War, to a meeting with Tsar Nicholas II.

Many sailors perished that day and as such the wreck site is considered a war grave and restricted area for shipping and diving. In the run up to the centenary of the loss of the HMS Hampshire permission was given to carry out a condition survey and map the extent of the wreck site.

Sandra Henry continues: “This survey is being undertaken as a mark of respect and remembrance for those who lost their lives aboard, and all those who lost their lives at sea during the First World War.”

Equipped with a SeaBat T-50-P the wreck site was mapped in great detail. The imagery confirmed previous findings that HMS Hampshire capsized as she sank and lies with an upturned hull on the seabed in approximately 60m of water. The superstructure itself is compressed and the hull is damaged in places throughout the length of the vessel. The data was recorded and processed with Teledyne PDS.

Myrtle

Tue, 28 Mar 2017 09:49:18 GMT

The gunnery ship-minesweeper Myrtle was built in England in 1915. The ship arrived to Estonia during the days of the War of Independence as part of the British squadron. The ship was sweeping the German mine barriers from the sea routes. Myrtle was lost on a German minefield near Harilaiu islet on 15 July 1919. The ship was severely damaged in the course of several mine explosions. There were casualties.

Dago

Tue, 28 Mar 2017 09:43:46 GMT

The steamship Dago was built in England in 1912 as a cargo ship. The ship was taken into use by the Russian navy during WWI, and was rebuilt as an armed minesweeper carrying the bow number 4. Dago was anchored West of Osmussaar island on 23 October 1915 due to bad weather, when she was attacked by the German submarine U-9. The torpedo was shot from a short distance and hit the minesweeper right in the center. The vessel foundered immediately.

7 Seven crew members were killed.

Wreck Survey In 600m Of Water

Fri, 22 Mar 2013 08:06:43 GMT

The video shows a WWI merchant vessel sunk using charges after surrendering to a German U-Boat. The bow separated from the vessel during its 600m decent to the seabed and lies half a kilometre away. No lives were lost.The video shows the 90m long main and stern section of the hull with a fishing net draped over the port side.

The survey was carried out using a 4 ton negatively buoyant platform usually used as a grab for cargo removal. The platform was equipped with a Reson 8125, CDL MiniPOSNAV3 inertial navigation system and Tritech Bathy suite and was tracked from the surface using an IXSEA GAPS USBL.The platform was suspended through the moonpool at 590m depth and survey lines were run around the wreck. The data shows a small heave artefact. This is due to the platform being directly connected to the surface vessel and suffering the same heave. The data quality was excellent so only a small amount of point removal was needed. The xyz file was then displayed in Cloud Compare and lighting applied to enhance the detail.

Sonar used: RESON SeaBAt 8125 with 1500m rated head.

SS Leslie aka The Carol Lee Wreck

Wed, 13 Mar 2013 07:36:52 GMT

SS Leslie The SS Leslie was built in 1919 in Duluth, Michigan, as the Lake Flagstaff. She later sailed under the names Stella Lykes and Josephine, before being renamed Leslie. She was 251 feet long, had a 44 foot beam and displaced 2,609 gross tons. The Leslie was owned by Worth Steamship Company of New York and was under the command of Captain Albert Ericksson. On April 12, 1942, she was torpedoed by the German submarine U-123. At the time she was en route from Antilla, Cuba, to New York with a cargo of 3,300 tons of sugar. Out of a complement of 31 crew and one passenger, four of her crew were lost.Today the Leslie wreck sits in 80 feet of water, 21 miles off Port Canaveral.

The wreck was surveyed in two passes and processed with PDS2000 grid model editor. It was surveyed with Land and Sea's research vessel " The Beast" a 40 foot Sea Ark. We used a Knogsberg MRU 5 motion sensor,an ADU5 Magellan heading device and a magellan RTK sub centimeter GPS system.

Mon, 11 Mar 2013 09:31:45 GMT

"Dutch Wreck" -- Steamship Laertes The Dutch steamship Laertes was built in 1919 by Taikoo Dockyard & Engineering Company, Hong Kong. Owned by Nederland Stoomy, she was 423.9 feet long, had a 52.3 foot beam, displaced 5,825 tons and was pushed by a single screw triple expansion engine. The Laertes was powered by a 413 nhp triple expansion engine and had a top speed of 13.5 knots.On May 3, 1942, the Laertes was torpedoed and sunk by a German submarine. Some say it was the work of the U-564, while others claim it was the U-109. At the time she was on a voyage from New York to Bombay, with a 5,230 ton cargo of war supplies, including three aircraft, 17 tanks and 20 trucks. A total of 18 of her crew went down with her.

Today the Laerte's scattered wreckage sits in 72 feet of water eleven miles off Port Canaveral. This wreck is also locally known as the Dutch WreckThe data was processedusing the grid model editor in Teledyne PDS
