The video, published by the American Geophysical Union (AGU), seeks to explain the ever-lasting phenomenon of green icebergs in the Antarctic. Researchers recently proposed a new idea that may explain why some Antarctic icebergs are tinged emerald green rather than the normal blue, potentially solving a decades-long scientific mystery.
Arctic’s icecap is shrinking 12% faster than it was a decade ago, and nearly all of its older and thicker ice is already gone. Nick Hughes, who leads the Norwegian Ice Service addressed the possibility that in 2045 all vessels might be able to sail straight over the top of the world.
US Coast Guard released images of the Cutter Polar Star, that caught fire in the ship’s incinerator room about 650 miles north of McMurdo Sound, Antarctica. After the attempts of four fire extinguishers failed, the fire crew was trying to extinguish fire for two hours.
Russian gas producer Novatek plans to use nuclear icebreakers to keep the Northern Sea Route open all year long for its LNG. The Arctic is considered as one of the most challenging shipping routes. However, lately more and more ships actually prefer this route. The company plans to keep the Northern Sea Route open the whole year between 2023-2025. This will be achieved by using 100-megawatt-hour nuclear icebreakers.
The Australian Royal Navy has deployed its Laser Airborne Depth Sounder (LADS) Flight to Invercargill in New Zealand, to undertake survey operations over Macquarie Island, a 34km long World Heritage listed island that lies approximately halfway between Australia and Antarctica.
Polaris, as being the newest addition to Finland’s fleet, is the first icebreaker that runs on LNG, a lower-carbon alternative to the diesel fuel which powers most large ships. The icebreaker is keeping shipping lanes open for about six months, enabling the voyage of cargo ships that carry steel, paper products and chemicals in and out of the ports serving northern Finland and neighbouring Sweden.
IMO’s Sub-Committee on Ship Design and Construction (SDC 6), which took place on 4-8 February 2019, considered a first set of draft recommendations for fishing vessels and pleasure yachts operating in Polar waters, but are not already covered by the mandatory Polar Code, the so-called ‘non-SOLAS’ ships.
The US Congress passed a spending package last week under which the US Coast Guard will receive a US$675 million funding for new icebreakers. The USCG is namely receiving $655 million to start construction on the lead ship for a new class of Polar Security Cutters.
As the meeting of IMO’s Sub-Committee on Pollution Prevention and Response (PPR 6) opens today in London, the Clean Arctic Alliance called on Member States to give emphasis to the target of establishing a ban on the use and carriage of heavy fuel oil by shipping in the Arctic. The actual adoption of the ban is expected to take place on 2021, with the industry making its decision on what fuels it will use during 2022. The ban will apply in 2023.
As climate change melts Greenland’s glaciers and deposits more river sediment on its shores, researchers identified an unexpected economic opportunity for the Arctic nation. Namely, exporting excess sand and gravel abroad, where raw materials for infrastructure are in high demand. This solution was developed by scientists from CU Boulder, the University of Copenhagen, Arizona State University and the Rhode Island School of Design.
