American WW2 submarine found off Japanese coast

Published

Underwater archaeologists have found the wreck of the USS Albacore off the Japanese coast.

USS Albacore (SS-218) was a Gato-class submarine, which served in the Pacific Theatre of Operations until she was lost at sea in 1944.

Albacore′s keel was laid on 21 April 1941 by the Electric Boat Company in Groton, Connecticut. She was launched on 17 February 1942, sponsored by Mrs. Elise Riles Cutts, and commissioned on 1 June 1942.

During her two years of active service, the USS Albacore was awarded the Presidential Unit Citation and nine battle stars.

On the 24th October, 1944, the Albacore left Pearl Harbor to patrol the Japanese coast. After loosing all contact with the submarine, the Albacore was presume lost with all hands and was stricken from the Naval Vessel Register.

According to Japanese naval records, a submarine (presumed to be the Albacore) exploded after it struck a mine of the shores of Hokkaidō on 7 November 1944.

A sonar survey of the area in 2022 by Dr. Tamaki Ura of the University of Tokyo, detected what appeared to be a submarine hull 7 kilometres east of Hakodate. A remotely operated underwater vehicle to photographic and video evidence of the wreck site, which were sent to the Naval History and Heritage Command at the historic Washington Navy Yard for identification.

In a recently issued press release, the Naval History and Heritage Command has confirmed that the submarine is indeed the USS Albacore, based on several key features of a late 1944 Gato-class submarine, including documented modifications of the SJ Radar dish and mast, a row of vent holes along the top of the superstructure, and the absence of steel plates along the upper edge of the fairwater.

“As the final resting place for Sailors who gave their life in defense of our nation, we sincerely thank and congratulate Dr. Ura and his team for their efforts in locating the wreck of Albacore,” said NHHC Director Samuel J. Cox, U.S. Navy rear admiral (retired). “It is through their hard work and continued collaboration that we could confirm Albacore’s identity after being lost at sea for over 70 years.”

Researchers find evidence of ceremonial offerings beneath Maya ballcourt

Published

Archaeologists from the University of Cincinnati have found ceremonial offerings beneath a Maya ballcourt in Mexico.

Using environmental DNA analysis, researchers were able to identify a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah.

The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor upon which a ballcourt was built.

Researchers said the ancient Maya likely made a ceremonial offering during the ballcourt’s construction.

“When they erected a new building, they asked the goodwill of the gods to protect the people inhabiting it,” UC Professor David Lentz said. “Some people call it an ensouling ritual, to get a blessing from and appease the gods.”

The research was carried out through Mexico’s National Institute of Anthropology and History in collaboration with researchers from the University of Calgary, the Autonomous University of Campeche and the National Autonomous University of Mexico.

Researchers from 2016 to 2022 worked at Yaxnohcah in Campeche about 9 miles north of the border of Guatemala, where they excavated a small area of a ballcourt.

The ancient Maya played several ball games, including pok-a-tok, which has rules similar to soccer and basketball. Players tried to get a ball through a ring or hoop on a wall.

UC Professor Emeritus Nicholas Dunning said when buildings were expanded or repurposed, as with the ballcourt, the ancient Maya made offerings to bless the site. Archaeologists sometimes find ceramics or jewelry in these offerings along with plants of cultural significance.

“We have known for years from ethnohistorical sources that the Maya also used perishable materials in these offerings, but it is almost impossible to find them archaeologically, which is what makes this discovery using eDNA so extraordinary,” Dunning said.

Ancient plant remains are rarely discovered in tropical climates, where they decompose quickly. But using environmental DNA, researchers were able to identify several types known for their ritual significance.

They discovered evidence of a morning glory called xtabentun, known for its hallucinogenic properties, lancewood, chili peppers and jool, the leaves of which were used to wrap ceremonial offerings.

Botanist and UC Associate Professor Eric Tepe said finding evidence of these plants together in the same tiny sediment sample is telling. He has studied modern plants in the same forests once traveled by the ancient Maya.

“I think the fact that these four plants which have a known cultural importance to the Maya were found in a concentrated sample tells us it was an intentional and purposeful collection under this platform,” Tepe said.

Researchers noted the challenge of trying to interpret a collection of plants through the opaque lens of 2,000 years of prehistory. But Lentz said the findings help add to the story of this sophisticated culture.

Researchers believe the ancient Maya devised water filtration systems and employed conservation-minded forestry practices. But they were helpless against years-long droughts and also are believed to have deforested vast tracts for agriculture.

“We see the yin and yang of human existence in the ancient Maya,” Lentz said. “To me that’s why they’re so fascinating.”

Archaeologists explore submerged Mesolithic site of Bouldnor Cliff

Archaeologists from the University of Warwick are conducting an underwater study to document the submerged Mesolithic site of Bouldnor Cliff before it vanishes due to erosion.

Bouldnor Cliff is situated in the Solent between the Isle of Wight and the southern coast of England. The site was first discovered in 1999 when divers observed a lobster discarding worked flint tools from its burrow on the seabed.

At a time when Britain was cut off from mainland Europe by rising sea levels, the area of the Solent was a river valley inhabited by an advanced Mesolithic community who developed a boat building technology 2,000 years ahead of their time.

The study aims to find new data on the nature of the late Ice Age environment during the development of the Mesolithic era, and the extent of the interaction between the inhabitants of Bouldnor Cliff and Europe, including the exchange of materials.

Professor Robin Allaby, who is leading the expedition, said: “This is an incredible opportunity to understand the lost world in which the Mesolithic developed using the latest techniques before our chance is gone.”

The study will involve a comprehensive palaeoenvironmental analysis, in addition to state-of-the-art techniques such as optical simulated luminescence for constructing ecological profiles. Furthermore, archaeologists intend to recover archaeological artefacts and environmental markers to reconstruct the past environment.

Dr Kinnaird adds: “This is an exciting research project to showcase the new innovations in luminescence dating, which can tell when an object was last exposed to the Sun. The relevance of this technique in writing the narratives for 4000 years of history, at the time that the British coastline was rapidly changing, is huge!”

According to the researchers, these discoveries carry the potential to significantly transform our comprehension of the era when Britain emerged as an island.
