The Fate of a Lake After a Dramatic Mining Disaster
Researchers tracked long-term sediment dynamics in Canada’s Quesnel Lake following the 2014 failure of a dam that spilled record-breaking amounts of contaminated mining waste.
Probing the Sedimentology of a Continental Megathrust
Detailed analysis of sediments covering the Main Frontal Thrust in Nepal show how climate-driven baselevel changes affect sedimentation and should be considered when inferring thrust activity.
Volcanic Winters Ushered in the Jurassic Reign of the Dinosaurs
Sediment cores from northwestern China reveal freezing conditions during the Late Triassic killed off many forms of life—but not dinosaurs.
Bangladeshis Feel Increased Consequences of Sedimentation
In northern Bangladesh, residents are losing their livelihoods, homes, and personal safety when water carries sand and gravel into their communities.
River Floods Can Trigger Powerful Underwater Landslides
A record-length turbidity current triggered by river flooding has revealed a new link between the surface and the deep sea.
Searching for Earth’s Oldest Rocks in its Youngest Deposits
By sampling and analyzing zircons from glacial eskers dating from about 20,000 years ago, the extent of the oldest known rocks on Earth can be better mapped and constrained.
A Unique Glimpse at Sediment Erosion and Deposition by Wind
The Lut Desert in Iran is an exceptional natural laboratory to study how wind moves sediment across the landscape. A new study quantifies erosional and depositional sediment fluxes of the desert.
Atmospheric Rivers Help Coastal Wetlands Build Up Sediment
Accounting for these storms and flooding can help experts predict and respond to rising sea levels.
Satellites Show Magnitude of Human Influence on River Sediment Flux
Dam-building has decreased the amount of sediment transported by rivers, while land use changes have increased the amount.
