  • Arctic warming interrupts the Transpolar Drift and affects long-range transport of sea ice and ice-rafted matter | Scientific Reports
    https://www.nature.com/articles/s41598-019-41456-y

    Sea ice is an important transport vehicle for gaseous, dissolved and particulate matter in the Arctic Ocean. Due to the recently observed acceleration in sea ice drift, it has been assumed that more matter is advected by the Transpolar Drift from shallow shelf waters to the central Arctic Ocean and beyond. However, this study provides first evidence that intensified melt in the marginal zones of the Arctic Ocean interrupts the transarctic conveyor belt and has led to a reduction of the survival rates of sea ice exported from the shallow Siberian shelves (−15% per decade). As a consequence, less and less ice formed in shallow water areas (<30 m) has reached Fram Strait (−17% per decade), and more ice and ice-rafted material is released in the northern Laptev Sea and central Arctic Ocean. Decreasing survival rates of first-year ice are visible all along the Russian shelves, but significant only in the Kara Sea, East Siberian Sea and western Laptev Sea. Identified changes affect biogeochemical fluxes and ecological processes in the central Arctic: A reduced long-range transport of sea ice alters transport and redistribution of climate relevant gases, and increases accumulation of sediments and contaminates in the central Arctic Ocean, with consequences for primary production, and the biodiversity of the Arctic Ocean.

  • Russia Is Hunting For Its Crashed Nuclear-Powered Cruise Missile And The U.S. Might Be Too - The Drive
    http://www.thedrive.com/the-war-zone/23058/russia-is-hunting-for-its-crashed-nuclear-powered-cruise-missile-and-the-u


    (je reprends ici l’intégralité de l’article, non accessible en France)

    Russia is reportedly set to launch an operation to recover a prototype of its Burevestnik nuclear-powered and nuclear-armed cruise missile that came down in the Barents Sea in 2017. At the same time, the wreckage presents a prime opportunity for other countries, particularly the United States, to gain major insights into its design and true capabilities.

    CNBC was first to report the Russian expedition, citing unnamed U.S. government sources with knowledge of an American intelligence report on the matter, on Aug. 21, 2018. These individuals said that the Kremlin would dispatch three unspecified ships, including one specially configured to recover the missile’s nuclear reactor, but said there was no set timeline for when the operation would begin or how long it might last. 
    Russia test-fired four Burevestniks in total between November 2017 and February 2018, according to the new information. The longest test flight reportedly lasted over two minutes and saw the weapon travel a total of 22 miles, while the shortest experiment saw the missile fail within seconds, but it still managed to cover a distance of five miles. The missile reportedly uses a nuclear reactor to power its propulsion system, giving it theoretically unlimited range.

    The Russians have otherwise been very tight-lipped about the design, which read more about here. So, it’s not surprising that they would want to recover any wrecks both to prevent foreign intelligence services from getting their hands on it and to gather more information for their test program.

    The official video below offers the best views of the Burevestnik cruise missile available to date.

    Though CNBC did not say which Russian ships might be heading out on the recovery mission, it is very possible that the Yantar might be among them. Officially an “oceanographic research vessel,” this spy ship has specialized equipment that can reportedly tap or cut submarine cables and investigate and retrieve objects from depths of up to 18,000 feet.

    In 2017, the vessel reportedly sailed off the coast of Syria to recover the remnants of two fighter jets, a Su-33 and a Mig-29KR, that crashed into the Mediterranean Sea during operations from Russia’s aircraft carrier Kuznetsov. In that case, the goal was also, at least in part, to make sure other countries could not retrieve the wrecks for their own purposes.

    In June 2018, the U.K.’s Royal Navy escorted Yantar through the English Channel as it headed into the North Sea. Pictures showed a Saab SeaEye Tiger deep-sea robot on the ship’s deck. Russia acquired this piece of equipment after the Kursk submarine disaster. The Tiger can reach depths of 3,280 feet and private companies have previously used them to do work at sites with heavy radioactive contamination.

    It’s not clear what state the missile wreckage, or the weapon’s reactor, might be in. We at The War Zone have previously explored in detail what might happen if these weapons came down on land or over water after reports that they were crashing first emerged earlier in 2018. It’s also worth noting that these apparent failures might have been successes depending on the actual test points and would have provided Russia important information for further development of the Burevestnik regardless.

    Of course, if the weapon is at all salvageable, the race may be on for the Russians to get it off the bottom of the Barents Sea before anyone else does. The United States has already reportedly been keeping a close eye on the tests and could have a good idea of where the missiles have landed. 

    If they spread any substantial amount of radioactive material when they came down, it might make them even easier to locate. In February 2017, well before the reported test flights, a U.S. Air Force WC-135 atmospheric reconnaissance aircraft was flying around the Barents Sea on what the service has insisted was a routine mission. This coincided with reports of increased radioactivity in the region, but that might have been linked to leaking Russian nuclear waste facilities.

    That U.S. Navy has its own deep sea intelligence gathering and salvage capabilities, notably the super-secret Seawolf-class submarine the USS Jimmy Carter. In September 2017, again before Russia reportedly began firing Burevestniks, that boat returned to its homeport at Naval Base Kitsap-Bangor in Washington State flying a Jolly Roger flag, a symbol representing the completion of a particularly successful mission.

    The U.S. government has a long history of trying to steal sensitive Russian equipment from the bottom of the ocean, as well. In the 1970s, the Central Intelligence Agency famously used the Hughes Glomar Explorer to pull a portion of the Soviet Golf II-class ballistic missile submarine K-129 up from the depths of the Pacific Ocean.

    Getting ahold of or even examining pieces of a #Burevestnik, one of six super weapons Russian President Vladimir Putin highlighted in a speech in March 2018, would be a major coup for American intelligence agencies and the U.S. government’s foreign partners. NATO as a whole is also becoming more concerned with Russia’s aggressive policies and various advanced weapons developments, amid threatening training exercises, electronic warfare attacks, and deceptive information operations.

    All told, it might be worth keeping an eye on Yantar’s movements to see if she heads out into the waters above the Arctic Circle any time soon.

    Update: 5:20pm EST
    Canadian analyst Steffan Watkins has found that Russia’s Akademik Primakov, a seismic research vessel has been recently sailing a very deliberate pattern in the Kara Sea, which is to the east of the Novaya Zemlya archipelago. To the west of Novaya Zemlya is the Barents Sea and the area was home to Soviet nuclear weapon testing.


    @steffanwatkins
    Russian seismic research vessel Akademik Primakov (MMSI:273392760) is certainly looking for something in the Kara Sea at 5kn. (Before you get too excited, it could be mapping the Arctic shelf, to aid in Russian claims to it.)

    It is possible that the initial report of where the missile went down was inaccurate and that it instead crashed into the Kara Sea. However, as Watkins notes, the Akademik Primakov is more likely mapping the region. The Russian company JSC Sevmorneftegeofizika acquired the ship in June 2017 specifically to conduct geological exploration activities in the Arctic Shelf.

    Chinese shipping companies have sent a dozen vessels through the waters of the Northern Sea Route (NSR) in 2017, compared to five vessels the previous year. This is the largest fleet of non-Russian flagged vessels to ever operate on the route. In addition, the Xue Long, a Chinese icebreaker, also spent nearly three months sailing the Arctic Ocean, including Canada’s Northwest Passage.

    China’s Ocean Shipping Company utilized the route for five transit voyages — three westbound from Asia to Europe and two eastbound from Europe to Asia — and three destination trips to deliver modules for Yamal LNG to Sabetta. Guangzhou Salvage also delivered modules for Yamal LNG. In addition China’s National Offshore Oil Corporation and China’s Oilfield Services Limited conducted seismic and drilling activities in the Kara Sea.

    The rapid increase of Chinese activity on the route follows the country’s intent to benefit from the opening of Arctic shipping routes.

    “The NSR has officially become part of the maritime component of China’s One Belt One Road project after the publication of China’s National Development and Reform Commission and the State Oceanic Administration’s vision for Maritime Cooperation under the Belt and Road Initiative,” explains Ekaterina Klimenko, Researcher at the Stockholm International Peace Research Institute.

  • Sibérie et libération de méthane

    http://siberiantimes.com/science/casestudy/news/n0905-7000-underground-gas-bubbles-poised-to-explode-in-arctic

    Methane exceeded the norm 1,000 times, while carbon dioxide was 25 times above the norm. Initial measurements had suggest methane levels 200 times above usual levels.

    Some 15 examples of this swaying Siberian ground were revealed last July on Bely Island, a polar bear outpost some 750 km north of the Arctic Circle in the Kara Sea. One research team account at the scene said: ‘As we took off a layer of grass and soil, a fountain of gas erupted.’

    American companies such as ExxonMobil have been severely affected by the sanctions on Moscow. In September last year, ExxonMobil and Rosneft announced that they had struck oil at Universitetiskya-1 in the Kara Sea in the Russian Arctic, a region that is fast becoming a geo-strategic hub for Russia.

    Under pressure from Washington, however, ExxonMobil has wound down drilling on the project and the company has said that it is facing a $1 billion loss on its investments in Russia due to the sanctions.

  • Arctic city hopes to cash in as melting ice opens new sea route to China

    via @fil qui a repéré cet article fort à propos...

    The city of Nadym, in the extreme north of Siberia, is one of the Earth’s least hospitable places, shrouded in darkness for half of the year, with temperatures plunging below -30C and the nearby Kara Sea semi-permanently frozen.

    But things are looking up for this Arctic conurbation halfway between Europe and China. Over the next 30 years climate change is likely to open up a polar shipping route between the Pacific and Atlantic oceans, cutting travel time to Asia by 40% and allowing Russia’s vast oil and gas

  • Arctic Shipping Soars, Led by Russia and Lured by Energy

    http://news.nationalgeographic.com/news/energy/2013/11/131129-arctic-shipping-soars-led-by-russia

    A momentous season is ending for the world’s newest nautical shortcut.

    Stable ice began forming in mid-October along the coast of Siberia’s Yamal Peninsula, the large landmass north of the Arctic Circle that juts into the Kara Sea. The freeze was expected to spread steadily west and southwest, inundating Kara Strait (map) by this week.

    Once nature closes that narrow strait to the Barents Sea, it effectively shuts down until next summer the entrance to Russia’s Northern Sea Route (NSR), the 3,000-mile (4,828-kilometer) east-west passage between Europe and Asia that global warming has made possible.
