Robot Boat Maxlimer Maps Underwater Tongan Volcano That Erupted Last January

Posted on by August 24, 2022

Last January, a major underwater eruption of the Hunga-Tonga Hunga-Haʻapai (HTHH) volcano caused a tsunami that hit the Pacific country of Tonga. Now, the BBC reports that a robot vessel, the 12m-long Uncrewed Surface Vessel (USV) Maxlimer, has returned from an initial survey, having completed a partial mapping of the opening, or caldera, of the underwater volcano.

The Maxlimer may be in Tonga, but it is being remotely controlled from 16,000km away in the small coastal village of Tollesbury in Essex. Everything is done over a satellite link.

In a dark control room, several large screens display live feed images from the 10 cameras on board Maxlimer. Operators, who work in shifts around the clock, watch as real-time data gets beamed in from the South Pacific.

Dolmen of Guadalperal, AKA the Spanish Stonehenge, Emerge From Drought-Stricken Reservoir

Posted on by August 22, 2022

We recently posted about “hunger stones” revealed by falling water levels in the Rhine and Elbe rivers, as well as the emergence of a graveyard of sunken German warships filled with explosives and ammunition in the Serbian section of the Danube River, all caused by a near-record European drought.

In the Extremadura region of Spain, a far less threatening historical structure has emerged from the receding waters of Valdecanas reservoir — a megalithic monument officially known as the Dolmen of Guadalperal but dubbed the Spanish Stonehenge, comprising a circle of dozens of stones believed to date back to 5000 BC.

Wrecks of Dozens of Explosive-Laden Nazi Ships Exposed By Drought in Serbian Danube

Posted on by August 21, 2022

One of the worst droughts in European history has exposed a graveyard of sunken German warships filled with explosives and ammunition in the Serbian section of the Danube River. More than 20 hulks have emerged near the port town of Prahovo, part of a Nazi Black Sea fleet that was sunk in 1944 while fleeing Soviet forces. More ships are expected to be found lodged in the river’s sandbanks, loaded with unexploded ordnance.

“The German flotilla has left behind a big ecological disaster that threatens us, people of Prahovo,” said Velimir Trajilovic, 74, a pensioner from Prahovo who wrote a book about the German ships.

A bit over a year ago, we posted about the construction of a new Maryland Dove by the Chesapeake Bay Maritime Museum shipyard. The ship, a reproduction of the 17th-century trading ship that accompanied the first settlers to what is now Maryland in 1634, has been completed after three years of construction and is on her way to her homeport of Historic St. Mary’s City.

The new Maryland Dove is the third replica of the historic ship to be built. The first was built in 1934 to commemorate Maryland’s tercentenary. The second, in 1977, has served as a floating exhibit for Historic St. Mary’s City.

Reports that China Has Developed Prototype Submarine Flying Drones

Posted on by August 19, 2022

There are reports that researchers from Nanjing University of Aeronautics in eastern China have developed a prototype flying submarine drone capable of operating underwater or in the air.

According to a report by the South China Morning Post, the flying submarine can support various military missions, including the detection of underwater mines.

Chinese professor Ji Wanfeng says the new drone will make it possible to disrupt the defense systems of enemy aircraft carriers. The drone can dive underwater to avoid radar. When detected by sonar, the drone can take off into the air. According to the professor, the simultaneous use of several such drones could overwhelm the computer systems of aircraft carriers.

Update: Submarine Secrets Espionage Plea Deal Falls Through

Posted on by August 18, 2022

Virginia Class Submarine

The Washington Post reports that a federal judge rejected plea bargains for a Navy engineer and his wife who allegedly tried to sell military secrets, saying the prison terms called for by the deals were too lenient for a couple accused of offering U.S. nuclear submarine data to a foreign government.

Last October, we posted about Navy nuclear engineer Jonathan Toebbe, and his wife, Diana Toebbe, who were arrested after attempting to pass detailed secret information about the US Navy’s Virginia-class submarine reactors to foreign agents. The Toebbes left a 16 GB memory card containing submarine documents and plans, hidden in half of a peanut butter sandwich in a plastic bag at an agreed location in West Virginia. They thought that they were giving the information to a foreign country in exchange for cryptocurrency payments. Instead, the FBI had intercepted their correspondence and impersonated foreign agents.

Hunger Stones Emerge as Extreme Drought Drops Water Levels of Rhine & Other European Rivers

Posted on by August 17, 2022

Extreme drought has dramatically lowered water levers in major European rivers, including the Rhine, Elbe, Loire, Danube, and Po. On the Rhine, river depths have dropped close to levels seen in the record drought of 2018. The shallow water resulting have prevented many vessels from navigating the critical European shipping route fully loaded. Barges are operating at roughly 25 % of full load capacity to avoid running aground.  Experts warn that the low water on major rivers could significantly damage Germany’s economy.

The Guardian notes that the Rhine, which runs about 760 miles from the Swiss Alps to the North Sea, is the second largest river in central and western Europe after the Danube. The majority of nearly 200 million tons of cargo shipped on German rivers – from coal to car parts, food to chemicals – is transported on the Rhine.

Wreck of USS Jacob Jones Found Off Isles of Scilly — First US Destroyer Lost to Enemy Action

Posted on by August 14, 2022

British divers have located the wreck of the USS Jacob Jones in over 100 meters of water, 40 miles off the Isles of Scilly. The ship, a Tucker Class destroyer, was sunk during World War I by a German U-boat on December 6, 1917. USS Jacob Jones was the first US destroyer ever to be lost to enemy action and went down in 8 minutes. 64 of her crew of 110 were lost in the attack.

As recounted by the Naval History and Heritage Command: Approximately one month after the United States declared war on Germany, the destroyer steamed to Queenstown [Cobh], Ireland, under Lieutenant Commander David W. Bagley with Division Seven of the Destroyer Force, the second group of destroyers to enter the war zone. Arriving at the British base on 17 May 1917, Jacob Jones operated out of Queenstown, patrolling the U-boat-infested western approaches to the British Isles. Later, as the Entente Powers instituted a worldwide convoy system, the destroyer escorted inbound and outbound convoys through the submarine danger zone.

Update: Restoration of Ex-Presidential Yacht Sequoia to Begin Soon in Belfast, Maine

Posted on by August 13, 2022

Good news. The Bangor Daily News is reporting that the restoration of the ex-presidential yacht Sequoia will begin soon in Belfast, Maine.

We first posted about the saga of the ex-presidential yacht in 2016 when Delaware judge Sam Glasscock describes her then-current condition. “The Sequoia, an elderly and vulnerable wooden yacht, is sitting on an inadequate cradle on an undersized marine railway in a moribund boatyard on the western shore of the Chesapeake, deteriorating and, lately, home to raccoons.”

Three years later we posted again, about the 104′ long motor vessel being loaded aboard a barge to be transported to Maine for restoration.

Now, following the pandemic and supply chain issues, Todd French of French & Webb, a local custom boat building company described the progress in the restoration of the historic yacht to the Bangor Daily News. Continue reading →

Arctic Warming Four Times Faster Than the Rest of the World

Posted on by August 12, 2022

The rapid warming of the Arctic, a definitive sign of climate change, is occurring even faster than previously described. A new report by the Finnish Meteorological Institute concludes that the Arctic has warmed at about four times the global average rate over the last 43 years. Specifically, Arctic Circle — the area located above 66.5 degrees latitude — has warmed by more than 5 degrees Fahrenheit since 1979.

The Scientific American also reports that a separate group of scientists presented research at the annual meeting of the American Geophysical Union last December with similar findings. And just in June, another study by a different research team also cited a four-times Arctic warming figure (Climatewire, July 11).

The Mortar Wreck: Oldest Surviving UK Shipwreck Near Dorset Coast

Posted on by August 11, 2022

Over 750 years ago, a medieval ship loaded with a cargo of limestone, carved gravestones, and mortars for grinding, sank off the Dorset coast a mile away from the nearest harbor.  Now the so-called Mortar Wreck has been granted the highest level of protection on the advice of Historic England.

The 13th-century wreck, discovered in Poole Bay in Dorset, is the oldest known protected wreck in English waters where hull remains can be seen. Tree ring dating of the wreck indicates that the timbers used to construct the hull are from Irish oak trees, felled between 1242-1265, during the reign of King Henry III.

Orcas Continue to Attack Sailboats Off Portugal & Spain — First Boat Sunk in Attack

Posted on by August 9, 2022

In 2020 and 2021, orca whales started attacking sailboats and fishing boats cruising off the Iberian peninsula and in the Mediterranian near the Strait of Gibraltar. Pods of juvenile orcas rammed sailboats and often grabbed their rudders or keels. More than 50 rogue orca attacks were reported in 2020 and 2021. So far, scientists are at a loss to explain the behavior.

This year, the attacks have continued. Last week, there was a report of a sailboat being sunk in an attack by a pod of orcas, 11 km off the port of Sines, Portugal. Five crew members were rescued by a fishing vessel in the coordination of the Portuguese Navy. This was the first reported case of a boat being sunk by an orca attack in the Atlantic.
