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.

Deep Cenezoic Sediments in Front of the Barbados Ridge Complex, Odp Site 672: Hemipelagites, Turbidites, and Possible Contourites in Western Central Atlantic Ocean Sédiments cénozoïques au front du complexe de la Barbade, site ODP 672 : hémipélagites, turbidites, et possibles contourites dans l'Atlantique central occidental

Oil & Gas Science and Technology, 2006
The cenozoic sediments cover of western central Atlantic oceanic floor was cored at about 5 000 m depth, close to the deformation front of the Barbados Accretionary Prism.

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Sediment transport and depositional hydrodynamics on the eastern Korean continental margin revealed by surface sediment granulometry

Sedimentology, Volume 73, Issue 5, Page 1469-1487, August 2026.
ABSTRACT Terrigenous sediments are transported from coastal areas and shelves to deeper continental margins by multiple processes. Understanding these processes is critical for evaluating the ecological impacts of fine‐grained sediment deposition and predicting future changes in sediment dispersal under rapid climate change.

Marine Sediment Record of Eruption‐Fed Vertical Density Currents, Kermadec Arc (Rangitāhua)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Products of explosive volcanism can be transported into the oceans, where they form marine tephra layers. The processes responsible for their deposition are often complex, involving multiple transport mechanisms. During the RV Investigator voyage IN2022‐V02 (2022), a 35‐cm‐thick marine tephra unit was piston‐cored at 2,460 m water depth in the

Submarine fans: A critical retrospective (1950–2015)

Journal of Palaeogeography, 2016
When we look back the contributions on submarine fans during the past 65 years (1950–2015), the empirical data on 21 modern submarine fans and 10 ancient deep-water systems, published by the results of the First COMFAN (Committee on FANs) Meeting (Bouma ...

Regional Variations in Sea Ice and Primary Productivity in the Bering Sea During Marine Isotope Stage 11

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Marine Isotope Stage (MIS) 11 (424–374 ka) has long been an analog for Holocene climate because it is the most recent interglacial period with similar orbital conditions. However, there is global and regional variability in the climate response to MIS 11 warmth.

The hyperpycnite problem

Journal of Palaeogeography, 2018
Sedimentologic, oceanographic, and hydraulic engineering publications on hyperpycnal flows claim that (1) river flows transform into turbidity currents at plunge points near the shoreline, (2) hyperpycnal flows have the power to erode the seafloor and ...
