Thresholds for Environmental
Signal Storage in Stratigraphy
Alluvial basins provide important records of climate and tectonic changes on Earth, as well as information about how land surfaces evolve under
different boundary conditions. These deposits also contain important energy and water reserves and will serve as hosts for carbon capture and
storage. Consequently our ability to reliably interpret and predict stratigraphic patterns is fundamentally important both scientifically and in
its bearing on broader society. Building on earlier statistical studies, we are examining the fidelity of the stratigraphic record in laboratory
and numerical experiments. In these experiments, we also quantify the depositional architecture that controls the 3D structure of the strata.
This architecture is influenced by both stochastic (autogenic) and deterministic (allogenic) processes. Specifically, we are investigating the
temporal and spatial scales necessary for changes in forcing conditions (including sea level and/or sediment flux) to be stored in the
stratigraphic record. This work helps improve efforts at recovering signalss of changing boundary conditions in ancient basins, and modeling
and predicting stratigraphy in alluvial basins.
