Natural and anthropogenic influences on the development of mud depocenters in the southwestern Baltic Sea

open access: yesOceanologia, 2023
The morphological evolution of two mud depocenters in the southwestern Baltic Sea is investigated by comparison of numerical model results to geological and oceanographic data.

The influence of the Pb Content of Source Transport on its Distribution in the Bottom Layer [PDF]

open access: yesE3S Web of Conferences, 2020
Based on the survey data of Jiaozhou Bay in 1992, the vertical distribution and seasonal variation of Pb in the surface and bottom waters from the bay center to the south of the bay mouth were studied, and the seasonal distribution, range and horizontal ...

On the Dependency of Bottom Drag and the Eddy Viscosity upon Flow Structure in the Coastal Boundary Layer

open access: yesJournal of Marine Science and Engineering, 2022
The physical processes governing coastal exchange between the surf zone, the inner shelf, and the open ocean is critical for estimating mass exchange and its impact on ecological processes.

Exploring the three-dimensional flow-sediment dynamics and trapping mechanisms in a curved estuary: The role of salinity and circulation

open access: yesFrontiers in Marine Science, 2022
Combined with the observed data in the wet season in June 2015, structures of longitudinal and lateral residual current and characteristics of the estuarine turbidity maximum (ETM) in the Yongjiang estuary (YE) are studied using a three-dimensional ...

Dilution in a dense bottom jet in cross currents

open access: yesWater Science and Technology, 1998
A 3-dimensional numerical model describing the dilution in the near field around dense vertical jets in a cross flow is formulated and validated against laboratory experiments. The validation shows that the model reproduces the flow pattern well, though the dilution is underestimated by 20%.

Topographic and Sedimentary Controls on Submarine Canyon-Channel Systems Along the Adélie Land Margin

open access: yesJournal of Marine Science and Engineering
Submarine canyon-channel systems play a critical role as potential conduits for warm-water upwelling around Antarctica, potentially influencing ice-sheet stability. Integrating multibeam bathymetry, seismic profiles, and morphometric analysis, this study

Internal-wave-induced dissipation rates in the Weddell Sea Bottom Water gravity current [PDF]

open access: yesOcean Science
This study investigates the role of wave-induced turbulence in the dynamics of the Weddell Sea Bottom Water gravity current. The current transports dense water from its formation sites on the shelf to the deep sea and is a crucial component of the ...

NEAR-BOTTOM CURRENT MEASURED BY ACOUSTIC SENSORS

open access: yesCoastal Engineering Proceedings, 1978
A vertical current profile has been measured with three acoustic meters 60 cm, 100 cm and 200 cm from the sea bottom. The depth at the measuring site was 84 metres. The profile is found to depend on the time scale of the water particle motion. An Ekman-like turning of the current is also observed, and the thickness of friction layers is estimated ...

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

open access: yesTerrestrial, 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.
