'Treasure Ship' Discovery Claim Raises Eyebrows

and it would provide evidence next week to support its claim. It was the “only entity in the world” to have discovered the ship, it said in a statement.The release was accompanied by photos and video of a wreck, including a section that appeared to show the ship’s name. It said the search team included experts from Britain, Canada and South Korea.“We believe there are gold boxes, and it’s historically proven,” company spokesman Park Sung-jin told Reuters. “The boxes were very tightly lashed, indicating there are really precious stuff inside.”The announcement

MH370 Search Comes to a Close

of 48 hours.Over the course of the MH370 mission, Ocean Infinity said it searched and collected data from over 112,000 km2 of ocean floor in just over three months of operational days. The total area far exceeded the initial 25,000 km2 target and nearly matches the area covered by the previous search team over a period of 2.5 years (the previous search was called off in January 2017 after scouring 120,000 km2). “I would firstly like to extend the thoughts of everyone at Ocean Infinity to the families of those who have lost loved ones on MH370,” said Oliver Plunkett, Ocean Infinity&rsquo

Sonar Images Show Historic Avro Arrow Discovery

A search team has recently unveiled images that show the first of nine Avro Arrow free-flight models believed to be sitting at the bottom of Lake Ontario.   Search program organizers OEX Recovery Group held a press conference in Toronto last Friday to unveil sonar and underwater camera images that showcase a free-flight Avro Arrow model launched in a series of tests from 1954 to 1957 as part of the Avro Arrow design program.   The free flight models were launched over Lake Ontario in a series of flight tests conducted in the 1950s as engineers developed the revolutionary Arrow, which

WHOI scientists used deep-sea vehicles, including Sentry to locate the voyage data recorder (above) from the El Faro on the seafloor 15,000 feet deep. The VDR offers clues to understand why the ship tragically sank in 2015, killing 33 crew members aboard. (Photo: NTSB)

, that could reveal clues to understand what happened, but it was lost in the depths.   The VDR was mounted on the mast on the ship’s navigation bridge. A search expedition mounted in October located the wreck and discovered that the bridge had separated from the hull. Days later, when the search team located the bridge, the mast and the VDR were not on it. In April 2016, the National Transportation and Safety Board (NTSB) asked for help from Woods Hole Oceanographic Institution, calling in two deep-sea vehicles WHOI operates for scientific research.   Aboard the WHOI-operated research

Phoenix has been involved in the search for MH370 since April 2014, initially using its 5,000 meter depth-rated autonomous underwater vehicle (AUV) Artemis, and Hydrospheric Solutions Inc. 6,000 meter depth-rated ProSAS-60 towed synthetic aperture sonar system. The MH370 international search team, under the leadership of the ATSB, has searched more than 110,000 km2 of seafloor

MacArtney Equipment Aids Deep-sea Search for MH370

advanced vehicle handling system MacArtney won the tender to supply a MERMAC R40 winch for a Benthos deep tow sonar system. The winch is to be installed on board the search and rescue vessel Nan Hai Jiu 102 and the search for flight MH370 is going to be reinitiated in June 2016 by an Australian-based search team.   MacArtney describes it MERMAC R electrically driven winch as a robust and advanced vehicle handling system which safely controls the launch, operation and recovery of ROVs and towed vehicle systems.    Featuring high power and speed, minimal maintenance requirements, a rugged

Now that the VDR has been located, the WHOI team is using detailed photographs from Sentry to make photo mosaics of the location to plan the eventual recovery of the VDR. The team also continues
