U.S. Revives Cold War Submarine Spy Program to Counter China
underwater sensors: one in Challenger Deep in the Mariana Trench, the deepest known point on earth; the other near Yap, an island in the Federated States of Micronesia. Though China says these sensors are used for scientific purposes, they could detect submarine movements near the U.S. naval base on Guam, a Pacific island territory, the Navy sources said.China’s Ministry of Defense did not respond to requests for comment about any aspect of this story. China's Foreign Ministry declined to comment.The U.S. Navy’s surveillance push is driven by three main factors, according to the
Inside the Subsea Cable Firm Secretly Helping America Take on China
.SubCom’s Coughlan helped Slattery pull off his first major cable deal in the late 2000s, setting him on course to become one of Australia’s wealthiest tech moguls, according to two industry sources with knowledge of the matter.That project, a SubCom-built cable running between Brisbane and Guam, a U.S. Pacific island territory that’s also home to a naval base, almost bankrupted Slattery, the businessman told the Australian Financial Review in a 2016 interview.Thanks to sympathetic suppliers, Slattery got that cable, known as PIPE, over the line, according to the Financial Review article

The vessel was set to transit from San Diego to Guam to begin an unrelated scientific expedition, and the survey could be performed without disrupting the transit schedule. Vessel staff including Captain Ian Lawrence and marine technician Daniel Yang, who operated the sonar, helped image the guyot on April 4, 2019.Sandwell said that geophysicists can
US Nuclear Sub Hits 'Object' in Asia-Pacific
condition of anonymity, said the incident took place in international waters in the South China Sea and that fewer than 15 people suffered minor injuries like bruises and lacerations. Two of the injuries were categorized as "moderate."The officials added that the submarine was now headed toward Guam under its own power for further inspection.It was unclear so far what the submarine hit, the officials said.(Reporting by Idrees Ali Editing by Bill Berkrot
Winners of Captain Don Walsh Award for Ocean Exploration Announced
General Bathymetric Chart of the Oceans (GEBCO) Seabed 2030 project.After a second year of dives into the Challenger Deep, which included the first women to dive to the deepest depths, former astronaut Kathy Sullivan, the Pressure Drop surveyed the entire northern “Ring of Fire” from Guam to Alaska, discovering, mapping, and naming over 70 new underwater features. During the 2021 dives, Vescovo marked a personal 12th dive into the Challenger Deep, and discovered the deepest wreck in history, the U.S. World War II destroyer Johnston off the Philippine Island of Samar
US Navy Recovers Downed Helicopter from Record Ocean Depth
was deployed in March 2021 to the North Pacific to recovery a Navy CH-60S which was lost in January 2020 from the USS Blue Ridge (LCC-19). CURV successfully rigged and recovered the aircraft from 19,075 feet, a new SUPSALV Record. (Photo: U.S. Navy)The SUPSALV team met the contracted salvage vessel in Guam, completed mobilization of CURV and its deep-lift take-up reel, and departed for the five-day transit. Arriving on the crash site March17, the team began recovery operations. Pulled from its depth of 19,075 FSW, the MH-60S’s recovery broke SUPSALV’s own world depth record for an aircraft
NASA Asks Gamers, Citizen Scientists to Help Map World's Corals
. Using techniques originally developed to look at stars, these "fluid-lensing" cameras use complex calculations to undo the optical distortions created by the water over coral reefs.NASA has deployed these instruments – mounted on drones or aircraft – on expeditions to Puerto Rico, Guam, American Samoa, and elsewhere to collect 3D images of the ocean floor, including corals, algae and seagrass. However, the data alone do not tell the whole story of what's happening to the corals beneath the waves, which is why NASA needs help.Enter NeMO-Net, a video game in which players identify
