The Cadiz Contourite Channel: Sandy contourites, bedforms and dynamic current interaction [PDF]

Marine Geology, 2013
The Cadiz Contourite Channel is the largest and most prominent contourite channel in the middle slope of the Gulf of Cadiz, and is known to channelise the southern branch of the Lower Core of Mediterranean Outflow Water (MOW) as it flows westwards from the Gibraltar Gateway.

MERCURY INTRUSION POROSIMETRY TO EVALUATE THE INCIDENCE OF BIOTURBATION ON POROSITY OF CONTOURITES

Rivista Italiana di Paleontologia e Stratigrafia, 2021
The effect of bioturbation on rocks’ flow-media properties (e.g., porosity and permeability) and its impact on reservoir quality has been previously documented.

First Evidence of Contourite Drifts in the North-Western Sicilian Active Continental Margin (Southern Tyrrhenian Sea)

Journal of Marine Science and Engineering, 2021
We present the results of an integrated geomorphological and seismo-stratigraphic study based on high resolution marine data acquired in the north-western Sicilian continental margin. We document for the first time five contourite drifts (marked as EM1a,

Bioclastic bottom‐current deposits of a Devonian contourite terrace: Facies variability and depositional architecture (Tafilalt Platform, Morocco)

Sedimentology, 2023
The study examines bioclastic carbonate contourites that arise from the broad spectrum of bottom‐current related sedimentary processes ranging from deposition to erosion.

Ferromanganese nodules and micro-hardgrounds associated with the Cadiz Contourite Channel (NE Atlantic): Palaeoenvironmental records of fluid venting and bottom currents [PDF]

, 2012
Ferromanganese nodule fields and hardgrounds have recently been discovered in the Cadiz Contourite Channel in the Gulf of Cadiz (850–1000 m). This channel is part of a large contourite depositional system generated by the Mediterranean Outflow Water ...

An assessment of bottom current controlled sedimentation in Pacific Ocean abyssal environments [PDF]

, 2018
The effect of the circulation of polar-sourced dense waters on the deep seafloor is still largely unknown. This paper presents multibeam bathymetric evidence for the existence of present-day contourite drifts on the central Pacific ocean at depths ...

Seismic characteristics of sediment drifts: An example from the Agulhas Plateau, southwest Indian Ocean [PDF]

, 2001
Sediment drifts provide information on the palaeoceanographic development of a region. Additionally, they may represent hydrocarbon reservoirs. Because of this, sediment drift investigation has increased over the last few years. Nevertheless, a number of

The economic importance of contourites [PDF]

Geological Society, London, Special Publications, 2007
Abstract The importance of contour currents in shaping and building continental margins has long been accepted. Their economic implications and the stratigraphic framework in which they are developed remain largely unknown. Data retrieved from sidescan sonar images, seismic profiles and their attribute maps, as well as sea-floor coring ...

Investigations on the Peach 4 Debrite, a Late Pleistocene Mass Movement on the Northwest British Continental Margin [PDF]

, 2010
The Peach 4 debrite is the most recent in a series of large scale Pleistocene MTDs within the Barra fan on the northwest British continental margin. Geophysical data indicate that Peach 4 was formed through a combination of blocky and muddy debris flows
