Bottom Current Modification of Turbidite Lobe Complexes

Frontiers in Earth Science, 2022
Submarine lobes form at the distal end of sediment gravity flow systems and are globally important sinks for sediment, anthropogenic pollutants and organic carbon, as well as forming hydrocarbon and CO2 reservoirs.

An assessment of bottom current controlled sedimentation in Pacific Ocean abyssal environments [PDF]

Marine Geology, 2018
The effect of the circulation of polar-sourced dense waters on the deep seafloor is still largely unknown. This paper presents multibeam bathymetric evidence for the existence of present-day contourite drifts on the central Pacific ocean at depths ...

Gas plumes and near-seafloor bottom current speeds of the southernmost Okinawa Trough determined from echo sounders

Terrestrial, Atmospheric and Oceanic Sciences, 2019
Using echo sounders to detect gas plumes in seawater is common, especially in the context of hydrothermal circulation areas or gas hydrate-bearing cold seeps.

The Effects of Controlling Gas Escape and Bottom Current Activity on the Evolution of Pockmarks in the Northwest of the Xisha Uplift, South China Sea

Journal of Marine Science and Engineering
Submarine pockmarks are typical indicators of submarine gas escape activity. The deep strata of the Xisha Uplift are rich in biogenic and thermogenic gas, accompanied by strong bottom current activity.

Margin processes sculpting a land-detached canyon-channel system: the Gollum Channel System in the Porcupine Seabight

Frontiers in Earth Science, 2023
The land-detached Gollum Channel System (GCS) is one of very few large-scale canyon-channel systems on the Northwest European margin and thought to be of high importance in both along-slope and downslope sediment transport processes in the Porcupine ...

Bioclastic bottom‐current deposits of a Devonian contourite terrace: Facies variability and depositional architecture (Tafilalt Platform, Morocco)

Sedimentology, 2023
The study examines bioclastic carbonate contourites that arise from the broad spectrum of bottom‐current related sedimentary processes ranging from deposition to erosion.

Carbonate contourite drifts in the southwest South China Sea: Sedimentary, paleoceanographic and economic implications

Frontiers in Marine Science, 2022
Contourite drifts are significant sedimentary features and provide clues for the reconstruction of paleoceanography and paleoenvironment. Although they have been increasingly identified in the world’s ocean, shallow-water contourite drifts (< 300 m ...

Sediment Waves on the Western Slope of the Chukchi Rise (Arctic Ocean) and Their Implications for the Paleoenvironment

Journal of Marine Science and Engineering, 2022
Based on multibeam bathymetric data and high-resolution shallow sub-bottom profiles acquired during China’s 10th Arctic Scientific Expedition Cruise in 2019, a sediment wave field was found on the western slope of the Chukchi Rise, in the Arctic Ocean ...

Bottom‐Current Variability and the Relationship with Topography and Sedimentary Processes in the Drake Passage

Journal of Geophysical Research: Oceans, 2023
Bottom‐current related sediments have been commonly used for paleoceanographic reconstructions. However, the strength and variability of bottom currents are poorly understood and thus the processes that control sedimentation in deep environments are not ...

The effect of deep ocean currents on ocean- bottom seismometers records [PDF]

Natural Hazards and Earth System Sciences, 2023
Ocean-bottom seismometers (OBSs) are usually deployed for seismological investigations, but these objectives are impaired by noise resulting from the ocean environment.
