This study takes advantage of recent advances in field-based sediment motion monitoring to report direct field measurements of the bedload pick-up, or entrainment, function in natural grave...

The important role of floodplains and the broader riparian zone in providing temporary storage for a large fraction of the annual sediment load of rivers is well established, but this understanding is largely based on observations of the long-term av

Cosmogenic 7Be is a natural tracer of short-term hydrological processes, but its distribution in upland fluvial environments over different temporal and spatial scales has not been well described. We measured 7Be in 450 sediment samples collected fro

The conceptual model of non-cohesive ‘sortable silts’ in deep-sea muds that result from local, current-driven processes of size fractionation during entrainment and deposition has proven to be a useful tool for inferring qualitative changes in th

Isotopes of iodine play significant environmental roles, including a limiting micronutrient ( 127 I), an acute radiotoxin ( 131 I), and a geochemical tracer ( 129 I). But the cycling of iodine through terrestrial ecosystems is poorly understood, due

We report on the integration of subaerial and subaqueous surveys, on the basis of, respectively, SPOT satellite images and data acquired from a combined side-scan and profiler sonar system, of a barrier island on the west-central coast of Taiwan. Our

Reported here are results from new flume experiments examining deposition and entrainment of inert, silt-sized particles (with spherical diameters in the range from 20 to 60 μm) to and from planar, impermeable and initially starved beds underlying c

The geometries of alluvial fans and their upland catchments subject to known rates of basin subsidence V and upland precipitation P , respectively, are compared with predictions from a quantitative analysis of an idealized landscape. We find that the

During a basaltic fissure eruption heat transfer from the hot magma to the surrounding rock causes a dramatic increase in the magmatic viscosity and solidification at the margins. Both viscosity contrast and solidification can amplify initial variati
