Bowers Ridge
The Bowers Ridge is located in the southern part of the Aleutian Basin. It extends over in an arc, starting in the southeast at the Aleutian Arc and terminating to the northwest at the Shirshov Ridge. The Bowers Ridge arc separates the Aleutian Basin from the Bowers Basin, which it encloses. The ridge is not currently seismically active. The northern slope of the ridge is steeper than the southern slope. On the Aleutian side, the ridge is rimmed by a trough filled with a sedimentary sequence 9–10 km thick.E. V. Verzhbitsky, M. V. Kononov, and V. D. Kotelkin; Plate Tectonics of the Northern Part of the Pacific Ocean; Oceanology; 2007; Vol. 47; No. 5; pp. 705–717; The average age of the Bowers Ridge is about 30 My (Late Oligocene). Rock from the upper part of the Bowers Ridge was determined to be of Miocene age. Hence the Bowers Ridge and the southern part of the Shirshov Ridge The Shirshov Ridge is located on the eastern border of the Commander Basin below the Kamchat ...

Aleutian Basin
The Aleutian Basin is an oceanic basin under the southwestern Bering Sea. While the northeastern half of the Bering Sea overlies the North American Plate in relatively shallow water, the Aleutian Basin consists of oceanic plate—the remnant of the Kula Plate that was mostly subducted under the North American Plate. Subduction of the Kula Plate ceased after the creation of the Aleutian Trench to its south. What remained of the Kula Plate attached to the North American Plate. This former subduction zone is now the Beringian Margin, which now hosts sixteen submarine canyons, including Zhemchug Canyon, the world's largest. The deep-water part of the Bering Sea is separated into the Commander Basin and Bowers basins by the submarine Shirshov Ridge and Bowers Ridge. The Commander Basin occupies the western part of the Bering Sea, with the Shirshov Ridge on its eastern border. The Shirshov Ridge extends 750 km southward from the Russian Olyutorskii Peninsula to connect w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleutian Arc
The Aleutian Arc is a large volcanic arc in the U.S. state of Alaska. It consists of a number of active and dormant volcanoes that have formed as a result of subduction along the Aleutian Trench. Although taking its name from the Aleutian Islands, this term is a geologic grouping rather than a geographic one, and the Aleutian Arc extends through the Alaska Peninsula following the Aleutian Range to the Aleutian Islands. The Aleutian Arc reflects subduction of the Pacific Plate beneath the North American Plate. It extends from the Kamchatka Peninsula in the west to the Gulf of Alaska in the east. Unimak Pass at the southwestern end of the Alaska Peninsula marks the eastward transition from an intra-oceanic in the west to a continental arc in the east. Due to the arcuate geometry of the trench, the relative velocity vector changes from almost trench-normal in the Gulf of Alaska to almost trench-parallel in the west. Along the oceanic part of the subduction zone, convergence varies f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shirshov Ridge
The Shirshov Ridge is located on the eastern border of the Commander Basin below the Kamchatka Peninsula. It extends directly southward for a distance of 750 km toward the Aleutian arc in the eastern part of the Bering Sea (see figure).E. V. Verzhbitsky, M. V. Kononov and V. D. Kotelkin; Plate Tectonics of the Northern Part of the Pacific Ocean; Oceanology, 2007, Vol. 47, No. 5, pp. 705–717; The Shirshov Ridge rises 2–2.5 km above the surrounding basins. Although not immediately evident from the morphology, the Shirshov Ridge southern end extends to meet the northwesternmost portion of Bowers Ridge The Bowers Ridge is located in the southern part of the Aleutian Basin. It extends over in an arc, starting in the southeast at the Aleutian Arc and terminating to the northwest at the Shirshov Ridge. The Bowers Ridge arc separates the Aleutian ....
