What Controls the Shape of Steep Mountain Streams?

Sarah Stanley, Science Writer by Sarah Stanley 28 August 201727 April 2022

The shape of steep river streams changes systematically with channel slope, but field data and theoretical analysis reveal that slope is not the sole factor in setting a channel’s form.

Researchers use cosmogenic isotopes to study ocean river transport.

On-the-Ground Measurements Overestimate Earth’s Albedo

by David Shultz 18 August 20176 July 2022

Weather stations can be used to calibrate and validate albedo measurements from satellites, but they fail to account for variability across landscapes, overestimating how reflective our planet is.
