Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract It is recognized that mantle plumes play a direct role in generating regional uplift and producing immense volumes of basaltic magmatism, both of which can influence paleoclimate. The Icelandic Plume, beneath the North Atlantic Ocean, is of particular importance due to its size and position at a significant paleoceanographic gateway.

Report and preliminary results of RV METEOR Cruise M78/3. Sediment transport off Uruguay and Argentina: from the shelf to the deep sea ; 19.05.2009 – 06.07.2009, Montevideo (Uruguay) – Montevideo (Uruguay) [PDF]
, 2012 The waters off Uruguay and Northern Argentina offer the possibility to study sediment transport processes from ‘source-to-sink’ in a relatively small area.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Tectonic subsidence, sea level, and paleoclimate reconstructions using marine records rely on accurate decompaction of the sediment column. Over time, increased overburden pressure from burial decreases sediment porosity with depth. The porosity‐depth relationship is lithology‐dependent and can be represented by an exponential function ...

Evolution of contourite drifts in regions of slope failures at eastern Fram Strait [PDF]
arktos, 2019 Geotechnical characteristics of contouritic deposition often lead to preconditioning slope instabilities and failures along glaciated and formerly glaciated continental margins. However, internal depositional geometry is also an important factor in triggering instabilities. This work highlights the importance of the tectonic and oceanographic evolution

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.Abstract Dense shelf water (DSW) formed on Antarctica's continental shelves is a significant precursor for Antarctic Bottom Water (AABW), a critical component of global overturning circulation. We hypothesize that DSW cascades off the central Ross Sea shelf generated density currents that entrained sediment as they flowed down Hillary Canyon, resulting

Contourite or turbidite?: magnetic fabric of fine-grained Quaternary sediments, Nova Scotia continental rise [PDF]
, 1984 Samples of three piston cores and one gravity core from the Nova Scotia continental rise (depths 4210-4925 m) have been examined to differentiate parallel-to-slope and downslope depositional processes in Quaternary deposits from a region presently ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Bulk (whole sample) magnetic properties of three‐hundred‐sixty‐two samples from five North Atlantic Ocean sediment cores are compared to the magnetic properties of five grain‐size fractions separated from the same samples. The relative abundance and magnetic properties of the size fractions are highly variable both within a core and among ...

Contourites and associated sediments controlled by deep-water circulation processes:State-of-the-art and future considerations [PDF]
, 2014 The contourite paradigm was conceived a few decades ago, yet there remains a need to establish a sound connection between contourite deposits, basin evolution and oceanographic processes.

Dynamic Controls on Salt Structures and Translation Velocity at Continental Rifted Margins
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Salt tectonics at rifted margins involves intricate interactions between weak, viscous evaporite layers and brittle sedimentary rocks. Geophysical data and geological interpretation offer valuable insights into evaporite structure formation and the average translation rate of evaporite and sediment layers on time scales of several million ...
