Much of the modern upper (proximal) Monterey fan is a channel–levee complex, the Upper Turbidite Sequence (UTS), that was deeply eroded after the channel breached a volcanic ridge to reach a deeper base level. Ages of sediment samples collected with the ALVIN submersible from the deepest outcrop within the channel–levee system, 390 m below the adjacent western levee crest, indicate that the UTS deposits accumulated at ≥1 m ka−1 during the last 500 ka. Neogene and Early Pleistocene sediment… 
Shallow-water longshore drift-fed submarine fan deposition (Moisie River Delta, Eastern Canada)
Submarine canyons and associated submarine fans are in some cases located at the end of a littoral cell where they act as conduits for the transfer of eroded terrigenous sediments to the marine
Dynamic response to strike-slip tectonic control on the deposition and evolution of the Baranof Fan, Gulf of Alaska
The Baranof Fan is one of three large deep-sea fans in the Gulf of Alaska, and is a key component in understanding large-scale erosion and sedimentation patterns for southeast Alaska and western
Channel formation by flow stripping: large‐scale scour features along the Monterey East Channel and their relation to sediment waves
The Monterey East system is formed by large‐scale sediment waves deposited as a result of flows stripped from the deeply incised Monterey fan valley (Monterey Channel) at the apex of the Shepard
Morphodynamic And Stratigraphic Evolution Of Self-Channelized Subaqueous Fans Emplaced By Turbidity Currents And Dilute Mudflows (Invited)
Abstract The formative mechanisms of many geologic features attributed to the passage of turbidity currents are still obscure due to the difficulties in documenting the dynamics of turbidity currents
Trail of sand in upper Monterey Canyon : Offshore California
Detailed sampling of the axis and flanks of upper Monterey Canyon (water depths of <1500 m) was undertaken using a remotely operated vehicle (ROV)-deployed vibracoring system. The objective was to
Delivery of terrigenous material to submarine fans: Biological evidence of local, staged, and full-canyon sediment transport down the Ascension-Monterey Canyon system
Submarine canyons are prevalent in the world’s oceans and are instrumental in transporting sediment from coastal regions to deep-sea fans. Conventional sediment parameters such as mean grain size,


Monterey Fan, Pacific Ocean
Monterey Fan is the largest modern fan off the California shore. Two main submarine canyon systems feed it via a complex pattern of fan valleys and channels. The northern Ascension Canyon system is
Processes of late Quaternary turbidity current flow and deposition on the Var deep‐sea fan, north‐west Mediterranean Sea
High-resolution seismic boomer profiles, with a vertical resolution of less than 1 m, together with piston cores and previous side-scan sonar data, are used to describe late Quaternary sedimentation
Age relationships of distributary channels on Amazon deep-sea fan: Implications for fan growth pattern
Seismic-reflection profiles and long-range side-scan (GLORIA) sonographs reveal the relative age relationships between the major distributary channels of the upper and middle Amazon deep-sea fan.
Biostratigraphic implications for the turbidite depositional processes on the Monterey deep-sea fan, Central California
ABSTRACT Recognition of the Pleistocene/Holocene boundary and biohorizons on the continental margin of California is complicated by turbidite deposition. The coiling ratio of Neogloboquadrina

Anatomy and Growth Pattern of Amazon Deep-Sea Fan as Revealed by Long-Range Side-Scan Sonar (GLORIA) and High-Resolution Seismic Studies
Imaging of the Amazon deep-sea fan with long-range side-scan sonar (GLORIA) has, for the first time, revealed the anatomy, trends, and growth pattern of distributary channels on this fan. Only one
