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.

Bottom currents play a major role in deep‐sea sedimentation, but their significance in the burial of organic carbon is poorly quantified at a global scale.

Contourite or turbidite?: magnetic fabric of fine-grained Quaternary sediments, Nova Scotia continental rise [PDF]
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 ...

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 ...

The analysis of high resolution morpho–bathymetric data on the Calabro Tyrrhenian continental margin (Southern Italy) enabled us to identify several morphological features originated by mass–wasting processes, including shallow gullies, shelf&

Thousands of cold-water coral mounds along the Moroccan Atlantic continental margin : distribution and morphometry [PDF]
Coral mounds formed by framework-forming cold-water corals pierce the seabed along most continental margins of the Atlantic Ocean and new sites are continuously being discovered.

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

Hybrid turbidite–contourite systems are present where gravity-driven and bottom-current processes interact. Although recent studies have advanced our understanding, deciphering the relative roles of downslope and alongslope processes in shaping the deep ...

Seasonal changes in glacial polynya activity inferred from Weddell Sea varves [PDF]
The Weddell Sea and the associated Filchner–Rønne Ice Shelf constitute key regions for global bottom-water production today. However, little is known about bottom-water production under different climate and ice-sheet conditions.
