Bottom Current Modification of Turbidite Lobe Complexes [PDF]

open access: yesFrontiers 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.

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

open access: yesFrontiers 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 ...

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

open access: yesFrontiers 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

open access: yesJournal 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 ...

Hunting paleoceanographic archives of ice sheet-ocean interaction in the northwestern Ross Sea, Antarctica

open access: yesFrontiers in Earth Science, 2023
The analysis of sedimentary deposits influenced by bottom currents in glaciated continental margins provides crucial insights into paleo-depositional and oceanographic conditions.

Analysis of mooring-observed bottom current on the northern continental shelf of the South China Sea

open access: yesFrontiers in Marine Science, 2023
The bottom current is an important component of the three-dimensional ocean circulation, which is of significance for the safeties of ocean bottom engineering and facilities, the research on sediment and pollutant transports, and the ecological ...

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

open access: yesNatural 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.

Tilt Observations at the Seafloor by Mobile Ocean Bottom Seismometers

open access: yesFrontiers in Earth Science, 2021
We have developed a broadband ocean bottom seismometer (BBOBS) and its new generation (BBOBS-NX) with the penetrator sensor system since 1999. With them, we performed many practical observations to create a new research category of ocean bottom broadband

Interannual Bottom-Intensified Current Thickening Observed on the Continental Slope Off the Southeastern Coast of Hokkaido, Japan

open access: yesFluids, 2022
By rotary empirical orthogonal function and coastal-trapped wave mode analyses, we analyzed current velocity data, collected from 2001 to 2016. The data were obtained by an acoustic Doppler current profiler, deployed upward at a location of 41°39.909′ N,

Large amount of settlement brought by the river [PDF]

open access: yesE3S Web of Conferences, 2021
Utilizing the survey dataset of Pb in waters from south of bay mouth to southeast of bay in October 1992, and applying the horizontal and vertical change models of matter content put forward by authors, we would calculate the horizontal loss amount ...
