The Amundsen Sea is an arm of the Southern Ocean off Marie Byrd Land in western Antarctica . It lies between Cape Flying Fish (the northwestern tip of Thurston Island ) to the east and Cape Dart on Siple Island to the west. Cape Flying Fish marks the boundary between the Amundsen Sea and the Bellingshausen Sea . West of Cape Dart there is no named marginal sea of the Southern Ocean between the Amundsen and Ross Seas. The Norwegian expedition of 1928–1929 under Captain Nils Larsen named the body of water for the Norwegian polar explorer Roald Amundsen while exploring this area in February 1929.

73-460: Dustin Island ( 72°34′S 94°50′W  /  72.567°S 94.833°W  / -72.567; -94.833  ( Dustin Island ) ) is an island about 18 nautical miles (33 km; 21 mi) long, lying 15 nautical miles (28 km; 17 mi) southeast of Cape Annawan , Thurston Island . The island forms the southeast limit of Seraph Bay. Download coordinates as: Thurston Island

146-460: A flexible material and anchored to the Amundsen Sea floor would be able to interrupt warm water flow. This approach would reduce costs and increase the longevity of the material (conservatively estimated at 25 years for curtain elements and up to 100 years for the foundations) relative to more rigid structures. With them in place, Thwaites Ice Shelf and Pine Island Ice Shelf would presumably regrow to

365-483: A state they last had a century ago, thus stabilizing these glaciers. To achieve this, the curtains would have to be placed at a depth of around 600 metres (0.37 miles) (to avoid damage from icebergs which would be regularly drifting above) and be 80 km (50 mi) long. The authors acknowledged that while work on this scale would be unprecedented and face many challenges in the Antarctic (including polar night and

949-409: The "tipping point" for Pine Island Glacier may have been passed in 1996, with a retreat of 200 kilometers (120 miles) possible by 2100, producing a corresponding 24 cm (0.79 ft) of sea level rise . It was suggested that these estimates were conservative. The modelling study also stated that "Given the complex, three-dimensional nature of the real Pine Island glacier ... it should be clear that

1022-743: The Amundsen Sea averages about 3 km (1.9 mi) in thickness. It is roughly the size of the state of Texas and is known as the Amundsen Sea Embayment (ASE); it forms one of the three major ice drainage basins of the West Antarctic Ice Sheet along with the Ross Sea Embayment and the Weddell Sea Embayment. Some scientists proposed that this region may be a weak underbelly of the West Antarctic Ice Sheet . The Pine Island and Thwaites Glaciers, which both flow into

1095-525: The Amundsen Sea, are two of Antarctica's largest five. Researchers reported that the flow of these glaciers increased starting in the mid-2000s; if they were to melt completely, global sea levels would rise by about 0.9–1.9 meters (3.0–6.2 feet). Other researchers suggested that the loss of these glaciers would destabilise the entire West Antarctic ice sheet and possibly sections of the East Antarctic Ice Sheet . A 2004 study suggested that because

The former would be the simplest intervention, yet equivalent to "the largest civil engineering projects that humanity has ever attempted". It is also only 30% likely to work. Constructions blocking even 50% of the warm water flow are expected to be far more effective, yet far more difficult as well.

4307-537: The original proposal suggested attempting this intervention on smaller sites, like the Jakobshavn Glacier in Greenland , as a test. They also acknowledged that this intervention cannot prevent sea level rise from the increased ocean heat content , and would be ineffective in the long run without greenhouse gas emission reductions. In 2023, it was proposed that an installation of underwater curtains , made of

4380-414: The post 1957–58 IGY period. Some engineering interventions have been proposed for Thwaites Glacier and the nearby Pine Island Glacier to physically stabilize its ice or to preserve it. These interventions would block the flow of warm ocean water, which currently renders the collapse of these two glaciers practically inevitable even without further warming. A proposal from 2018 included building sills at

4453-408: The prior 10 millennia. Volcanic activity may be contributing to the observed increase of glacial flow, although the most popular theory is that the flow has increased due to warming ocean water . This water has warmed due to an upwelling of deep ocean water due to variations in pressure systems, which could have been affected by global warming . In January 2010, a modelling study suggested that
