Stad Slide: Preconditioning and failure of one of the world's largest megaslides

Journal of Quaternary Science, Volume 40, Issue 8, Page 1392-1406, November 2025.
ABSTRACT Submarine landslides can generate tsunamis and pose risks to underwater infrastructure, but a lack of direct observations of such slides hinders our understanding of their development and hazard potential. Studying the morphology of past slides can offer insights into their preconditioning and failure.

Studying the past of Mediterranean outflow based on 230th excess inventories and contourites [PDF]

, 2013
The Mediterranean Outflow water (MOW) comes out from the Mediterranean Sea and then contours the northern slope of the Cadiz Gulf. Along its way to the southern Portuguese Margin, it divides itself into three levels flowing at different depths, 400 m ...

Mode of Continental Thinning and Breakup Along the North Iberian‐Armorican Conjugate Margins in the Bay of Biscay

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Continental breakup involves multiple extension styles; each linked to unique structural and sedimentary processes. High‐angle, low‐angle, listric and antilistric normal faults develop at different stages and positions during rifting. The Bay of Biscay and its margins, a prototypical example of magma‐poor rifted margins during Jurassic ...

Early Quaternary sedimentary processes and palaeoenvironments in the central North Sea [PDF]

, 2017
A number of elongate trough-like features are observed in the early Quaternary succession of the central North Sea basin. A definitive model of formation for the features remains unclear but the troughs may aid in our understanding of the depositional ...

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 ...

Echo character mapping and depositional processes on the western Svalbard continental margin

Polar Research
An echo character mapping study of the western Svalbard continental margin, based on ca. 3980 km of archived sub-bottom profile data, is presented. Four distinct echo character types are recognized.

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 ...

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.

Decreased Deep Water Oxygenation in the Western North Pacific During the Plio‐Pleistocene Transition

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract The deep North Pacific, a vast respired carbon reservoir, likely plays a key role in the Plio‐Pleistocene CO2 decline and global cooling, but evidence for this is lacking. Here, oxygenation change in the upper deep western North Pacific between 5.3 and 1.0 million years ago (Ma) is reconstructed using multiple organic and inorganic proxies ...
