Shredding of environmental signals by sediment transport

DJ Jerolmack, C Paola - Geophysical Research Letters, 2010 - Wiley Online Library
Landscapes respond to climate, tectonic motions and sea level, but this response is
mediated by sediment transport. Understanding transmission of environmental signals is …

Environmental signal propagation in sedimentary systems across timescales

BW Romans, S Castelltort, JA Covault, A Fildani… - Earth-Science …, 2016 - Elsevier
Earth-surface processes operate across erosionally dominated landscapes and deliver
sediment to depositional systems that can be preserved over a range of timescales. The …

Model shows that rivers transmit high-frequency climate cycles to the sedimentary record

G Simpson, S Castelltort - Geology, 2012 - pubs.geoscienceworld.org
Rivers are a major component of sediment routing systems that control the transfer of
terrigenous sediments from source to sink. Although it is widely accepted that rivers are …

How plausible are high-frequency sediment supply-driven cycles in the stratigraphic record?

S Castelltort, J Van Den Driessche - Sedimentary geology, 2003 - Elsevier
This paper is an attempt to quantify the plausible time scales of clastic sediment supply
variations at the entrance of sedimentary basins. Our approach is based on the sedimentary …

[HTML][HTML] Quantitative bounds on morphodynamics and implications for reading the sedimentary record

V Ganti, MP Lamb, B McElroy - Nature communications, 2014 - nature.com
Sedimentary rocks are the archives of environmental conditions and ancient planetary
surface processes that led to their formation. Reconstructions of Earth's past surface …

Buffered, incomplete, and shredded: The challenges of reading an imperfect stratigraphic record

KM Straub, RA Duller, BZ Foreman… - Journal of Geophysical …, 2020 - Wiley Online Library
Climate, tectonics, and life influence the flux and caliber of sediment transported across

Transformation of tectonic and climatic signals from source to sedimentary archive

JJ Armitage, RA Duller, AC Whittaker, PA Allen - Nature Geoscience, 2011 - nature.com
The Earth's sedimentary successions are an archive of past tectonic and climate events,.
The physical characteristics of the sediment record are controlled by three main factors: the …

Temporal buffering of climate-driven sediment flux cycles by transient catchment response

JJ Armitage, TD Jones, RA Duller, AC Whittaker… - Earth and Planetary …, 2013 - Elsevier
The marine sedimentary record can exhibit a systematic cyclicity that is consistent with
climate variability driven by Milankovitch-scale forcing. Milankovitch-band cyclicity is widely …

Linking fluvial bed sediment transport across scales

Y Zhang, MM Meerschaert… - Geophysical Research …, 2012 - Wiley Online Library

scale‐dependency generally observed in transport rates and captures the transient …

[HTML][HTML] Times associated with source-to-sink propagation of environmental signals during landscape transience

S Tofelde, A Bernhardt, L Guerit… - Frontiers in Earth …, 2021 - frontiersin.org
Sediment archives in the terrestrial and marine realm are regularly analyzed to infer
changes in climate, tectonic, or anthropogenic boundary conditions of the past. However …
