New hydroacoustic and core data reveal sediment transport patterns off Uruguay [PDF]

, 2010
Submarine landslides cause slope instabilities and might damage sea-floor infrastructure or even generate tsunami waves. Therefore it is of major importance to understand all processes related to gravity-driven mass wasting and slope stability at ...

Reconstruction of the formation history of the Darwin Mounds, N Rockall Trough: How the dynamics of a sandy contourite affected cold-water coral growth [PDF]

, 2016
Cold-water coral mounds, formed through a feed-back process of cold-water coral growth and sediment baffling, have been studied all along the NE Atlantic continental margin.

A Paleotectonic Atlas of the African Plate: Permian to Recent

Journal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

Authigenic Uranium Preservation and Bottom Water Oxygenation in the Scotia Sea

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Sedimentary uranium (U) and thorium (Th) isotopes are invaluable proxies to assess bottom water redox conditions, site‐specific sediment focusing and vertical rain rates. We investigate if authigenic uranium (aU) can serve as a proxy for bottom water ventilation at International Ocean Discovery Program Site U1537 in the Scotia Sea and we ...

Increasing impact of North Atlantic Ocean circulation on sedimentary processes along the passive Galicia Margin (NW Spain) over the past 40 million years

Frontiers in Earth Science
Off the Northwestern Iberian Peninsula, the vigorous bottom-current regime interacts with a complex seafloor topography inside the Galicia Interior Basin (GIB), which was tectonically shaped during the opening of the North Atlantic Ocean basin in ...

From Hydrocarbon to CO2 Storage: Unveiling the Potential of the Miocene Lille John Member in the Danish North Sea

Basin Research, Volume 37, Issue 5, September–October 2025.
Depositional evolution of the upper Miocene complex. ABSTRACT To achieve net‐zero carbon emissions by 2050, gigatonnes of CO2 must be captured and stored in the subsurface. Screening and exploration of prospective storage sites have thus gained momentum in recent years.

Deep-water bottom current dynamics: processes, products & challenges [PDF]

, 2013
Contourites are deep-water sedimentary deposits created under the influence of predominantly along-slope bottom currents. They are considered to be excellent deep-water recorders of global climatic change.

Studying Past Deep-ocean Circulation and the Paleoclimate Record in the Gulf of Cadiz [PDF]

, 2002
Deep marine currents are strongly influenced by climatic changes. They also deposit, rework, and sort sediment, and can generate kilometer-scale sedimentary bodies (drifts).

Bedform Growth Beneath Periodic Internal Solitary Waves Propagating Through a Tidal Flow

Journal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
Abstract Internal solitary waves (ISWs), ubiquitous to lakes and coastal oceans, have often been proposed as a mechanism for generating subaqueous sandwaves. Yet, the physical mechanisms underlying ISW‐driven bedform growth remain poorly understood.
