Rates of continental-scale sediment flux and denudation are similar between glacial and interglacial periods when the aggradation of glacier-eroded sediment inhibits fluvial erosion downstream.

Sedimentos radiactivos podrían haber construido los cratones de la Tierra
La meteorización de los primeros continentes podría haber puesto en marcha la formación de cratones, las raíces inmutables de los continentes.
Waves May Be Crashing on Titan’s Shores
A new study suggests that wind-driven waves could be sculpting the coastlines of the lakes and seas on Saturn’s largest moon.
Radioactive Sediments May Have Built Earth’s Cratons
Weathering of the earliest continents could have set in motion the formation of cratons, the immutable roots of continents.
Agricultural Lands Are Losing Topsoil—Here’s How Bad It Could Get
A new study says topsoil erosion is likely to increase under climate change, though policy changes now could help stem the loss.
Sand’s Role in Rerouting Meandering Rivers Is Bigger Than We Thought
Researchers delve into the dirt causing rivers to migrate.
Middle-of-the-Road Mountains Form the Best Carbon Sinks
Silicate rock weathering has a sweet spot: erosion that isn’t too fast or too slow.
A Better Way to Predict Arctic Riverbank Erosion
Permafrost thaw might cause Arctic riverbanks to erode more quickly. But a new study shows why these erosion rates aren’t as dramatic as some scientists feared.
Mars as a Driver of Deep-Sea Erosion
An analysis of breaks in deep-sea sediment links the geological record to a 2.4-million-year cycle that heats Earth and ventilates our oceans.
Sea Otters’ Appetite for Crab Is Helping Strengthen Estuary Banks
Apex predators can have a powerful impact on coastal erosion rates by keeping grazer populations down, but their influence has been largely overlooked.
