Middle to Late Pleistocene alluvial surface ages recorded by their spectral reflectance in Patagonia, Argentina

Autor: Andreas Ruby, Taylor Schildgen, Henry Crawford, Mitch D'Arcy, Victoria M. Fernandes, Hella Wittmann, Fergus McNab, Viktoria Georgieva

Alluvial surfaces like fluvial terraces can act as markers for past changes in sediment and water flux along alluvial rivers. By precisely dating terrace surfaces, we can begin to quantify how sedimentary signals propagate though river channels and b

Drainage-divide migration, controlled by rock-uplift and rainfall patterns, may play a major role in the geomorphic evolution of mountain ranges. However, divide-migration rates over geologic timescales have only been estimated by theoretical studies

Decoupling between fluvial aggradation-incision dynamics and paleo-denudation rates during the last glacial cycle, Crete, Greece

Autor: Richard Ott, Dirk Scherler, Karl Wegmann, Mitch D'Arcy, Susan Ivy-Ochs, Marcus Christl, Christoph Vockenhuber

The impact of Quaternary climate cycles on denudation as well as fluvial aggradation and incision is debated, especially in regions that did not experience glaciation. Here we present a record of paleo-denudation rates, and geochronologic data constr

Quantifying competing measures of sediment dynamics on alluvial fans: implications for reconstructing past environmental change

Autor: Alexander C. Whittaker, Sam Brooke, Mitch D'Arcy

The effects of climate change on eroding landscapes and the sedimentary record remains poorly understood. While sediment routing systems at the Earth’s surface should, in principle, record changes in past environmental boundary conditions, the exte

Recent developments in terrestrial cosmogenic nuclide (TCN) exposure dating and the reinterpretation of TCN boulder ages from moraines have improved our understanding of the glacial chronology in the Central Andes. According to these records, glacial
