The Bering Strait has been the subject of the scientific theory that humans migrated from Asia to North America across a land bridge known as Beringia when lower ocean levels – a result of glaciers locking up vast amounts of water – exposed a wide stretch of the sea floor, [1] both at the present strait and in the shallow sea north and ...
The dry prominence of Aconcagua is equal to its wet prominence (6960 m) plus the depth of the highest submerged col of the Bering Strait (about 40 m), or about 7000 m. Mauna Kea is relatively close to its submerged key col in the Pacific Ocean, and the corresponding contour line that surrounds Mauna Kea is a relatively compact area of the ocean ...
A bearing is the angle between the line joining the two points of interest and the line from one of the points to the north, such as a ship's course or a compass reading to a landmark. On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points.
West: There being no major islands, follow the coast to the Bering Strait. Many attempts were made to find a salt water exit west from Hudson Bay, but the Fury and Hecla Strait in the far north is blocked by ice. The eastern entrance and main axis of the northwest passage, the Parry Channel, was found in 1819.
The Bering Strait around Fairway Rock is relatively shallow — about 50 m (164 ft) in depth — and oceanographic transects show the island to lie near a current velocity minimum for the strait. [6] Ocean currents north of Fairway Rock are occasionally studied as an example of a real-world system where a Von Kármán vortex street is generated ...
During winter, the Bering Strait has historically been blanketed in ice. But this year, the ice has nearly vanished. "The usually ice-covered Bering Strait is almost completely open water," Zack ...
All nuclear icebreakers of Project 22220 will be able to change the draft from 10.5 to 8.1 meters, depending on the depth, which will allow them to work both at sea and in the mouths of Siberian rivers. [citation needed] Nuclear icebreakers of Project 22220 are powered by two RITM-200 reactors and capable of overcoming ice up to 3 meters thick.
The Fox Islands Passes are waterways in the Fox Islands area of the U.S. state of Alaska, connecting the Bering Sea with the North Pacific Ocean. From the southward and eastward, bound for Bering Sea, there are three passes used by deep-draft vessels, known collectively as the Fox Islands Passes, and respectively as Unimak, Akutan, and Unalga ...
