Cyclic steps are a type of upper flow-regime bedform consisting of trains of upstream-and
upslope-migrating bed undulations. The overriding flow is characterised by a series of …

Cyclic steps are long-wave (the ratio of wavelength to height is≫ 1), upstream-migrating,
upper-flow-regime bedforms bounded by internal hydraulic jumps (ie, transition from …

Abstract Autonomous Underwater Vehicles (AUVs) have a wide range of applications in
marine geoscience, and are increasingly being used in the scientific, military, commercial …

Turbidity currents, and other types of submarine sediment density flow, redistribute more
sediment across the surface of the Earth than any other sediment flow process, yet their …

Submarine gravity flows are a key process for transporting large volumes of sediment from
the continents to the deep sea. The location, volume, and character of the sediment …

The study combines interpretation of 3D seismic imagery of submarine sinuous channel
belts in offshore West Africa with observations from a range of outcrop analogues. Five main …

The processes within deep-sea sediment-routing systems are difficult to directly monitor.
Therefore, we rely on other means to decipher the sequence and relative magnitude of the …

Submarine channels have been important throughout geologic time for feeding globally
significant volumes of sediment from land to the deep sea. Modern observations show that …

Preservation of cyclic steps contrasts markedly with that of subcritical‐flow bedforms,
because cyclic steps migrate upslope eroding their lee face and preserving their stoss side …

Advances in acoustic imaging of submarine canyons and channels have provided accurate
renderings of sea‐floor geomorphology. Still, a fundamental understanding of channel …
