LakeCC: a tool for efficiently identifying lake basins with application to palaeogeographic reconstructions of North America
(
- Journal of Quaternary Science
, 2019)
Along the margins of continental ice sheets, lakes formed in isostatically depressed basins during glacial retreat. Their shorelines and extent are sensitive to the ice margin and the glacial history of the region. Proglacial ...
Climatic and Biotic Controls on Topographic Asymmetry at the Global Scale
(
- Journal of Geophysical Research: Earth Surface
, 2021-01-23)
Insolation differences play a primary role in controlling microclimate and vegetation cover, which together influence the development of topography. Topographic asymmetry (TA), or slope differences between terrain aspects, ...
Site Dependence of Fluvial Incision Rate Scaling With Timescale
(
- Journal of Geophysical Research: Earth Surface
, 2020-10-26)
Global measurements of incision rate typically show a negative scaling with the timescale over which they were averaged, a phenomenon referred to as the “Sadler effect.” This time dependency is thought to result from hiatus ...
An Exhumation Pulse From the Nascent Franciscan Subduction Zone (California, USA)
(
- Tectonics
, 2020)
We investigated a suite of metabasite blocks from serpentinite matrix and shale matrix mélanges of the California Coast Ranges. Our new data set consists of 40Ar/39Ar dates of amphibole and phengite and U-Pb dates of ...
Revisiting the Middle Eocene Climatic Optimum “Carbon Cycle Conundrum” With New Estimates of Atmospheric pCO2 From Boron Isotopes
(
- Paleoceanography and Paleoclimatology
, 2020)
The Middle Eocene Climatic Optimum (MECO) was a gradual warming event and carbon cycle perturbation that occurred between 40.5 and 40.1 Ma. A number of characteristics, including greater-than-expected deep-sea carbonate ...
An ~130 kyr Record of Surface Water Temperature and δ18O From the Northern Bay of Bengal: Investigating the Linkage Between Heinrich Events and Weak Monsoon Intervals in Asia
(
- Paleoceanography and Paleoclimatology
, 2020)
Millennial-scale reductions in monsoon precipitation, so-called Weak Monsoon Intervals (WMIs), have been identified in numerous paleoclimate records across the Afro-Asian monsoon domain throughout the last glacial-interglacial ...
Observations of Laboratory and Natural Slow Slip Events: Hikurangi Subduction Zone, New Zealand
(
- Geochemistry, Geophysics, Geosystems
, 2020)
Slow slip events (SSEs) are recognized as an important component of plate boundary fault slip, and there is a need for laboratory friction data on natural samples to guide comparisons with natural SSEs. Here, we compile a ...
Partitioning the Uncertainty of Ensemble Projections of Global Glacier Mass Change
(
- Earth's Future
, 2020)
Glacier mass loss is recognized as a major contributor to current sea level rise. However, large uncertainties remain in projections of glacier mass loss on global and regional scales. We present an ensemble of 288 glacier ...
Bayesian Calibration and Sensitivity Analysis for a Karst Aquifer Model Using Active Subspaces
(
- Water Resources Research
, 2019)
In this article, we perform a parameter study for a recently developed karst hydrological model. The study consists of a high-dimensional Bayesian inverse problem and a global sensitivity analysis. For the first time in ...
Relative quantification of wind erosion in argan woodlands in the Souss Basin, Morocco
(
- Earth Surface Processes and Landforms
, 2020)
The endemic argan woodlands cover large parts of South Morocco and create a characteristic landscape with areas of sparsely vegetated and bare soil surfaces between single trees. This unique ecosystem has been under extensive ...
