Mid-Miocene cooling and the extinction of tundra in continental Antarctica
A major obstacle in understanding the evolution of Cenozoic climate has been the lack of well dated terrestrial evidence from high-latitude, glaciated regions. Here, we report the discovery ofExpand

Field evidence for climate-driven changes in sediment supply leading to strath terrace formation
Along the South Fork of the Eel River in northern California, paleoerosion rates derived from 10 Be concentrations in late Pleistocene strath terrace sediment are a factor of 2 greater than erosionExpand

Large shift in source of fine sediment in the upper Mississippi river.
Although sediment is a natural constituent of rivers, excess loading to rivers and streams is a leading cause of impairment and biodiversity loss. Remedial actions require identification of theExpand

Earth is (mostly) flat: Apportionment of the flux of continental sediment over millennial time scales
We thank [Warrick et al. (2014)][1] for the Comment on our recent synthesis of 10Be-derived denudation rates ([Willenbring et al., 2013][2]), in which we suggested that gently sloping areas,Expand

Toward generalizable sediment fingerprinting with tracers that are conservative and nonconservative over sediment routing timescales
PurposeThe science of sediment fingerprinting has been evolving rapidly over the past decade and is well poised to improve our understanding, not only of sediment sources, but also the routing ofExpand

What does a mean mean? The temporal evolution of detrital cosmogenic denudation rates in a transient landscape
In equilibrium landscapes, 10 Be concentrations within detrital quartz grains are expected to quantitatively refl ect basin-wide denudation rates. In transient landscapes, though detrital quartz isExpand

Identifying Sediment Sources and Sinks in the Root River, Southeastern Minnesota
Excessive loading of fine sediment is a prominent cause of river impairment, not only due to direct effects on biota and habitat but because sediment is often laden with excess nutrients, metals, andExpand

Early maximum extent of paleoglaciers from Mediterranean mountains during the last glaciation
Mountain glaciers respond directly to changes in precipitation and temperature, thus their margin extent is a high-sensitivity climate proxy. Here, we present a robust 10Be chronology for the glacierExpand

Effects of a tectonically-triggered wave of incision on riverine exports and soil mineralogy in the Luquillo Mountains of Puerto Rico.
We document the long-term response of a tropical mountain stream to tectonics and show how this response exerts a first-order spatial control on the delivery of weatherable minerals to forest soilsExpand

The plateau glacier in the Sierra de Béjar (Iberian Central System) during its maximum extent. Reconstruction and chronology
Abstract A detailed study of the glacial morphology in the Sierra de Bejar (Iberian Central System) provided a data set of geomorphic indicators to reconstruct the paleoglaciers developed in thisExpand
