The stratigraphic record is famously fragmentary, but it is also full of short, relatively complete fragments — laminated siltstones, eolian cross sets, point bars — that record ordinary events at seasonal to annual resolution.
We developed ‘rivabar’, a graph-based Python tool that automatically extracts river centerlines and banklines from time-lapse satellite imagery, and use it to investigate how sediment load drives channel migration patterns and stratigraphic complexity in single-thread and multi-thread rivers.
Our detailed mapping and analysis of shelf-margin evolution in the northeastern Gulf of Mexico during the last half million years are useful as a process analog for older, poorly imaged, and/or locally sampled subsurface intervals there and in other settings with delta-fed submarine channels.
Three-dimensional analysis of a Cretaceous river avulsion node reveals the anatomy of channel evolution and provides insights into ancient fluvial processes on Earth and Mars
Marine turbidite paleoseismology relies on the assumption of synchronous triggering of turbidity currents by earthquake shaking to infer rupture extent and recurrence. Such inference commonly depends …
There has been debate over the processes acting on deep-water channels, with comparisons made to the evolution of meandering fluvial systems. We characterized a three-dimensional seismic-reflection da…
