An abyssal plain is defined as a flat region on the ocean floor, typically located at the base of a continental rise, with a gentle slope of less than 1:1000. It represents the deepest and flattest part of the ocean floor, usually found at depths between 4000 and 6500 meters.
23 Ιαν 2023 · Our data adds to this by showing that the Bering Sea abyssal plain has distinct densities and assemblages of megafauna within a transect (~1 km) and between transects (~100 kms), as well as striking differences with published data across and between basins (over 1000 kms).
1 Ιαν 2016 · Abyssal plains are flat areas of the ocean floor in a water depth between 3,500 and 5,000 with a gradient well below 0.1°. They occupy around 28 % of the global seafloor. The thickness of the sediment cover seldom exceeds 1,000 m, and the sediments consist of fine-grained erosional detritus and biogenic particles.
1 Ιουλ 2018 · These elongate, ridge-parallel hills and intervening valleys provide the characteristic fabric of the recently accreted and sparsely sedimented seafloor. Near-bottom investigations document that...
1 Ιαν 2008 · This chapter summarizes the characteristics, terminology, and processes involved with abyssal plain contourites. It presents key case studies from different abyssal-plain settings, namely––southern hemisphere basins, northern hemisphere basins, and equatorial abyssal basins.

1 Σεπ 2024 · We argue that the regional tectonics shaped and controlled the shift of provenance and sediment routing system, whereas the East Asian monsoon affected the sediment flux to the abyssal plains of the Southwest sub-basin in the South China Sea. 1. Introduction.
