Trapped Wave Mystery Solved
Using a new type of satellite altimetry, a study led by Oxford University has finally confirmed the theory that the cause of extraordinary global tremors in September - October 2023 was indeed two mega tsunamis in Greenland that became trapped standing waves.In September 2023, a bizarre global seismic signal was observed which appeared every 90 seconds over nine days – and was then repeated a month afterwards. Almost a year later, two scientific studies proposed that the cause of these seismic anomalies were two mega tsunamis which were triggered in the remote Dickson fjord in East Greenland by
Ocean Robots Explore the Role of ‘Marine Snow’ in Carbon Storage
in the project is the FluxCAM, a marine snow camera system designed to measure the sinking speeds of different-sized particles to reduce uncertainties in how much carbon the ocean absorbs from the atmosphere.Two FluxCAMs were installed on a deep-sea mooring in the Labrador Sea, between Newfoundland and Greenland, last year, along with a specially programmed drifting profiling float.Now, they have been joined by autonomous underwater gliders, which will measure ocean properties and carbon flux for five to six months.“However, the rate at which these particles sink and how much carbon is ultimately
Kongsberg Discovery Technology Sets Sail On One Ocean Expedition Research Voyage
how marine life is affected by ocean movements, and recording underwater noise, using hydrophones, to ‘listen’ for pollution and monitor marine mammals, such as whales.The One Ocean Expedition sets sail during One Ocean Week in Bergen, calling in at ports including Reykjavik, Nuuk (Greenland), Cambridge Bay (Canada), Seattle, La Paz (Mexico), Cartagena (Columbia), Cadiz, and Dublin. During its stop in Nice, France, vessel team members will participate in the 2025 UN Ocean Conference. Statsraad Lehmkuhl will return to Bergen in April 2026, in time for next year’s One Ocean Week
White House Could Bypass UN on Deep-Sea Mining
review process, according to two sources with direct knowledge of the deliberations.If signed, the order would mark U.S. President Donald Trump's latest attempt to tap international deposits of nickel, copper and other critical minerals used widely across the economy after recent efforts in Greenland and Ukraine. Trump earlier this month also invoked emergency powers to boost domestic minerals production.The International Seabed Authority - created by the United Nations Convention on the Law of the Sea, which the U.S. has not ratified - has for years been considering standards for deep-sea
A Graveyard for Glaciers
2 billion people rely on glacier and snowmelt for freshwater.Ice loss from glaciers contributed around 21% of the total sea-level rise over the period 1993–2018, around half the contribution from expansion due to ocean warming (42%) but larger than contributions from melting of the ice sheets in Greenland (15%) and Antarctica (8%).“The conversation about climate change can be very abstract, with many devastating statistics and sophisticated scientific models that may feel incomprehensible,” said Rice University anthropologist Cymene Howe back in 2019 when a memorial was unveiled, the
MoU Signed for Pan-Arctic Cable System
digital connectivity infrastructure.The MoU affirms the partners’ vested interests in establishing and executing a long-term strategy for jointly realizing the development and implementation of a pan-Arctic submarine cable system.Polar Connect is a proposed subsea cable on a direct route east of Greenland, close to the geographical North Pole, aiming to connect Europe, North America and Japan on the shortest possible route. NORDUnet is acting as a catalyst to form a Europe-based alliance to build the cable system and secure 10 % of the capacity of the fiber for European research and education.Currently
NOC Secures £11M for Early Warning Systems
the Atlantic Subpolar Gyre. Through more than £11 million in funding from the UK’s Advanced Research + Invention Agency (ARIA), NOC will lead the development of novel and innovative new ways to detect early warning signs of a change in the Atlantic Subpolar Gyre.Sitting just south of Greenland and Iceland, the Atlantic Subpolar Gyre is a key component of the global ocean’s circulation system, transporting heat around the planet and helping to regulate temperatures in Europe and North America.Its collapse could have a major global impact on our weather, food, and security, but existing
An Arctic “Beyond Recognition” Expected by 2100
Manitoba.“The Arctic is warming at four times the rate of the rest of the planet,” said Stroeve. “At 2.7 degrees Celsius of global warming, we will see more extreme and cascading impacts in this region than elsewhere, including sea-ice-free Arctic summers, accelerated melting of the Greenland Ice Sheet, widespread permafrost loss and more extreme air temperatures. These changes will devastate infrastructure, ecosystems, vulnerable communities and wildlife.”Under 2.7 degrees Celsius of warming, the Arctic region is likely to experience the following effects:• Virtually every

together during their time ashore and likely to be telling everyone how Nella Dan was always the first to get to Antarctica at the start of the season despite her newer, more powerful competition.The 75.5-metre Nella Dan made 124 voyages serving as a supply, expedition and research vessel in northeast Greenland and in Antarctica. She made the Arctic-Antarctic roundtrip each season for over 20 years.Built in 1961, Nella Dan quickly became the much-loved flagship of the J. Lauritzen polar fleet. After the passing of Knud Lauritzen, his wife Hannelore continued to sail on her.Families were encouraged to
