Alluvial rivers are conveyor belts of fluid and sediment that provide a record of upstream
climate and erosion on Earth, Titan, and Mars. However, many of Earth's rivers remain …

A unique synthesis of grain size-distance data is presented, comparing, for the first time,
grain size and fining trends in a wide range of modern and ancient axial sediment dispersal …

Earth's terrestrial topography evolves in response to the interaction of tectonics, climate, and
lithology. Recent discoveries suggest that the grain size of sediments produced on hillslopes …

Riverbeds often fine downstream, with a gravel‐bedded reach, a relatively abrupt gravel‐
sand transition (GST), and a sand‐bedded reach. Underlying this behavior, bed grain size …

The origin of the well‐known 'grain size gap'within the size range 1–10 mm in fluvial gravels
is explored in a laboratory experiment to ascertain the effect of hydraulic sorting. A widely …

River bed sediments often lack fine gravel between 1 and 5 mm, a phenomenon referred to
as the “grain size gap.” The gap corresponds to the rapid reduction in grain size associated …

In the current study, subsurface characteristics within the complex formation of the Shilabati
basin system of West Bengal, India, extending over an area of 3888 km2, have been …

An abrupt transition in bed grain size occurs in river systems. Over a short downstream
distance, often only a few channel widths, the bed surface fines from gravel (∼ 10 mm) to …

Earth has sustained continental glaciation several times in its past. Because continental
glaciers ground to low elevations, sedimentary records of ice contact can be preserved from …

Photosynthetic protists, named microalgae, are key players in global primary production.
The green microalga Chlamydomonas reinhardtii is a well‐studied model organism. In …
