Channel trajectories control deep-water stratigraphic architecture

Interpretation of deep-water channel deposits is challenging because the spatial arrangement of their constituent lithologies is highly variable. This variability is often thought to be a signature of…

The stratigraphic evolution of a submarine channel: Linking seafloor dynamics to depositional products

We investigate the relationship between the cross-sectional geomorphic expression of a submarine channel as observed on the seafloor and the stratigraphic product of long-lived erosion, bypass, and se…

How do basin margins record long-term tectonic and climatic changes?

A long-standing goal of sedimentary geoscience is to understand how tectonic and climatic changes are reflected in basin fill. Here, we use 14 numerical models of continental-scale sedimentrouting sys…

Grain-Size and Discharge Controls on Submarine-Fan Depositional Patterns From Forward Stratigraphic Models

Submarine fans are important components of continental margins; they contain a stratigraphic record of environmental changes and host large accumulations of oil and gas. The grain size and volume of s…

Submarine channels ‘swept’ downstream after bend cutoff in salt basins

Channel‐bend expansion and downstream translation, as well as vertical movements by aggradation and incision, set the stratigraphic architecture of channelized depositional systems. Early work on subm…

Conversion of tectonic and climatic forcings into records of sediment supply and provenance

Understanding how environmental forcings (e.g., tectonics, climate) are transformed by erosional landscapes into sedimentary signals is a critical component of inverting the stratigraphic record. Prev…
