Contourite characterization and its discrimination from other deep‐water deposits in the Gulf of Cadiz contourite depositional system [PDF]
Sedimentology, 2020 AbstractDespite numerous efforts to properly differentiate between contourites and other deep‐water deposits in cores and outcrops, reliable diagnostic criteria are still lacking. The co‐occurrence of downslope and along‐slope sedimentary processes makes it particularly difficult to differentiate these relatively homogeneous deposits.

Secondary flow in contour currents controls the formation of moat-drift contourite systems
Communications Earth & Environment, 2023 Ocean currents control seafloor morphology and the transport of sediments, organic carbon, nutrients, and pollutants in deep-water environments. A better connection between sedimentary deposits formed by bottom currents (contourites) and hydrodynamics is

Astronomically paced changes in overturning circulation in the Western North Atlantic during the middle Eocene [PDF]
, 2018 North Atlantic Deep Water (NADW) currently redistributes heat and salt between Earth’s ocean basins, and plays a vital role in the ocean-atmosphere CO2 exchange.

Analysis of Different Methodologies to Calculate Bouguer Gravity Anomalies in the Argentine Continental Margin [PDF]
, 2014 We have tested and used two methods to determine the Bouguer gravity anomaly in the area of the Argentine continental margin. The first method employs the relationship between the topography and gravity anomaly in the Fourier transform domain using ...

Architecture of North Atlantic contourite drifts modified by transient circulation of the Icelandic mantle plume [PDF]
, 2015 Overflow of Northern Component Water, the precursor of North Atlantic Deep Water, appears to have varied during Neogene times. It has been suggested that this variation is moderated by transient behavior of the Icelandic mantle plume, which has ...

Contourite channels – Facies model and channel evolution
Sedimentology, 2022 AbstractDespite the rise in published evidence of deep‐marine bottom current processes and associated deposits there are still very few documented outcrop examples. Herein are reported results of a contourite channel system related to the late Miocene palaeo‐Mediterranean Outflow Water in the Rifian Corridor, Morocco.

Frontiers in Earth Science, 2019 An estimated 8.3 billion tons of non-biodegradable plastic has been produced over the last 65 years. Much of this is not recycled and is disposed into the natural environment, has a long environmental residence time and accumulates in sedimentary systems

The “Corsica Channel Cold-Water Coral Province” (Mediterranean Sea)
Frontiers in Marine Science, 2020 Over 25 mounds have been identified in the Corsica Channel (Mediterranean Sea) through multibeam bathymetric mapping at depth of 400–430 m, with dimensions ranging from 70 to 330 m, achieving maximum heights of 25 m.
