  • Is Putin trying to knock out West's GPS network? EU aviation authorities claim satellites are under constant 'jamming' or 'spoofing' attacks disrupting navigation from Finland to the Mediterranean

    Russia has been accused of interfering with the global GPS navigation system during a major Nordic war game in Finland. European aviation authorities have said signals, heavily used by commercial aircraft, have been affected from Finland, through the Mediterranean and even as far as Iraq. Disruptions to Global Navigation Satellite Systems (GNSS), which include GPS, are caused by the 'jamming' or 'spoofing' of satellite signals. Since the war erupted on February 24, 'jamming and/or possible spoofing has intensified in geographical areas surrounding the conflict zone and other areas,' the European Aviation Safety Agency (EASA) said in an online bulletin Thursday.

    The European Union Aviation Safety Agency (EASA) has just published a Safety Information Bulletin warning of the increase in the probability of issues regarding the use of Global Navigation Satellite Systems (GNSS) or Global Positioning Systems (GPS). The notice goes out due to the ongoing conflict in Ukraine following its invasion by Russian forces.

It is upright, clear of the seabed and "in a brilliant state of preservation," he said.
  • Endurance: Shackleton's lost ship is found in Antarctic

    03/09/2022 1:01:01 AM PST · by Winniesboy · 57 replies
    Scientists have found and filmed one of the greatest ever undiscovered shipwrecks 107 years after it sank. The Endurance, the lost vessel of Antarctic explorer Sir Ernest Shackleton, was found at the weekend at the bottom of the Weddell Sea. The ship was crushed by sea-ice and sank in 1915, forcing Shackleton and his men to make an astonishing escape on foot and in small boats. Video of the remains show Endurance to be in remarkable condition. Even though it has been sitting in 3km (10,000ft) of water for over a century, it looks just like it did on the...
  • Shackleton’s Endurance Discovered in the Icy Waters of Antarctica

    Ernest Shackleton’s lost ice ship, Endurance, has been discovered in the waters of Antarctica’s Weddell Sea. Endurance was crushed and sunk by pack ice in 1915, during Shackleton’s failed attempt to cross the Antarctic continent, and remained lost to the depths for more than a century. Now, the wreck has been found, filmed and surveyed by members of the Endurance22 expedition, which set out in search of the shipwreck in February 2022. After weeks of surveying the seabed, the shipwreck was located in early March 2022, 100 years after Shackleton died in 1922.

    Smithsonian magazine ^ | Nov 2021 | By Jo Marchant
    Shipwrecks from this period are exceedingly rare. Unless a ship is buried quickly by sediment, the wood is eaten away over the centuries by shipworm, actually a type of saltwater clam. But these organisms don’t survive in the fresher waters of the Baltic, and archaeologists believe that much of Hans’ vessel and its contents are preserved. That promises them an unprecedented look at the life of a medieval king who was said to travel with an abundance of royal possessions, not only food and clothing but weapons, tools, textiles, documents and precious treasures. More than that, the relic provides a...

    "The maritime industry transports 90% of the world’s trade and cyberattacks on shipping increased 900% between 2017 and 2020, to the tune of one incident on a ship every day. How much of your supply chain runs across the ocean?" "“The disruption of ships, ports, communications and shipping lanes is a genuine threat. This is crippling to the larger economy/larger supply chains—especially with things stretched thin today,” says Steve Moore, chief security strategist at Exabeam. “Amazon is even building its fleet with its own technology to control these problems more effectively.”"

    The CEOs of the two largest commercial jet manufacturers in the United States warned against the deployment of expanded 5G internet in a letter to Secretary of Transportation Pete Buttigieg. On Monday, Dave Calhoun of Boeing and Jeffrey Knittel of Airbus Americas expressed concern about a plan by Verizon and AT&T to roll out the new technology on January 5th of next year, urging the Biden administration to intervene to postpone the adoption of the new 5G network. “5G interference could adversely affect the ability of aircraft to safely operate,” reads the letter. The letter echoed concerns from a report...
  • The Oldest Confirmed 'Message in a Bottle' Contained Some Fascinating Questions

    In 2018, a message in a bottle dating back to 1886 - 132 years ago - was found half-buried in the sand of a Western Australian beach. According to its contents, it spent more than a century swimming around, before it was discovered nearly 950 kilometres (590 miles) from where it was thrown off a ship in the Indian Ocean. Beachgoer Tonya Illman found the old gin bottle with a rolled-up message in January 2018, 50 meters (164 feet) from the shoreline at the high water mark on Wedge Island. Even though it was missing a cork, surprisingly both the...

    European-crafted glass beads found at three different indigenous sites in northern Alaska date back to the pre-colonial period of North America, in what is an intriguing archaeological discovery. Somehow, these blueberry-sized beads made their way from what is now Venice, Italy, to the Brooks Range mountains of Alaska at some point during the mid-to-late 15th century, according to new research published in American Antiquity. The authors of the paper, archaeologists Michael Kunz from the University of Alaska Museum of the North and Robin Mills from the Bureau of Land Management, suspect the beads were trade goods that, after passing through...

    New research published Wednesday revealed that abnormal bony growths in the ear canal, also called "surfer's ear" and often seen in people who take part in water sports in colder climates, occurred frequently in our ancient cousins who died out around 40,000 years ago. ...the findings may mean they fished far more frequently than the archaeological record suggests, the scientists behind the study published in journal PLOS One said. "It reinforces a number of arguments and sources of data to argue for a level of adaptability and flexibility and capability among the Neanderthals, which has been denied them by some...

    Homo Neanderthaliensis did not become extinct because of changes in climate. At least, this did not happen to the several Neanderthals groups that lived in the western Mediterranean 42,000 years ago. A research group of the University of Bologna came to this conclusion after a detailed paleoclimatic reconstruction of the last ice age through the analysis of stalagmites sampled from some caves in Apulia, Italy. The researchers focused on the Murge karst plateau in Apulia, where Neanderthals and Homo Sapiens coexisted for at least 3,000 years, from approximately 45,000 to 42,000 years ago... Data extracted from the stalagmites showed that...

    Ancient Neolithic villagers on the Carmel Coast in Israel built a seawall to protect their settlement against rising sea levels in the Mediterranean, revealing humanity's struggle against rising oceans and flooding stretches back thousands of years. An international team of researchers from the University of Haifa, Flinders University in Australia, the Israel Antiquities Authority and The Hebrew University uncovered and analysed the oldest known coastal defence system anywhere in the world, constructed by ancient settlers from boulders sourced in riverbeds from 1-2km near their village. In a study published today in PLOS ONE, Dr Ehud Galili from the Zinman Institute...

    "Having studied the skull of one of the men who went down with the Mary Rose, we found the bone structure was consistent with someone who had North African features, and DNA evidence seems to back this up," he said. "Today, with a much more mobile world population, it would have been harder to isolate, but in the 16th Century it's easier to pinpoint facial characteristics to a specific location. "Henry, as we've named him, had a broad nose bridge and wide cheek bones which are far more similar to skeletons found in Morocco or Algeria than those of the...

    Tension is running high between Greece and Turkey. The cause? Turkish Chief of the General Staff Gen. Hulusi Akar paid a visit to Imia, a pair of two small, uninhabited Greek islets in the Aegean Sea, on January 29. He was accompanied by the commanders of the Turkish land, naval and air forces.Imia – which Turkey calls “Kardak” – was a subject of yet another crisis in 1996 that brought Greece and Turkey to the brink of war. Although armed conflict was ultimately averted, Turkey still claims that the islands are Turkish, even though the islands in the Aegean are...

    Opalescent pools full of carbon dioxide have been found at the site of the second biggest volcanic eruption recorded in human history. The eruption in the Aegean Sea off the coast of Santorini wiped out the Minoan civilisation living along the coast in 1600 BC. The newly discovered pools were found forming at a depth of 250m. They is a series of interconnected white pools that have high concentrations of CO2 and scientists say they could shed light on future volcanic eruptions and answer questions about deep sea carbon storage. An international team of scientists used sophisticated underwater exploration vehicles...
