Efficient Organic Carbon Burial by Bottom Currents in the Ocean: A Potential Role in Climate Modulation

Geophysical Research Letters
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.

A Global Evaluation of Lithology‐Dependent Marine Sediment Compaction Parameters and Their Uncertainties

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 ...

Morphological Variability of Submarine Mass Movements in the Tectonically–Controlled Calabro–Tyrrhenian Continental Margin (Southern Italy)

Geosciences, 2019
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&

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.

Plio‐Pleistocene Antarctic Bottom Water Production in the Ross Sea Reconstructed From Hillary Canyon Levee Turbidites

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

Hybrid turbidite–contourite systems in the modern Tarakan Basin: seismic sedimentology and analogue for subsurface storage

Frontiers in Earth Science
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]

Climate of the Past, 2014
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.

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 ...

Beyond the Bulk: Magnetic Property Variations With Sediment Grain Size. Insights Into Process and Provenance

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 ...
