Research into the speed of oil biodegradation under deep water conditions shows that darker, deeper waters slow oil degradation and microbial activity.
Low clarity levels from 2017 caused by record drought and then record rains and high temperatures don’t negate progress on clarity overall.
As scientists monitor a mining waste cleanup in a deep lake with unusual water dynamics, they learn more about how these dynamics impact remediation efforts.
Researchers reveal that the Atlantic Meridional Overturning Circulation (AMOC) is weaker than it’s been in 1,600 years—and why.
Researchers have used sediment and tree ring analysis to connect human interference and flood risk in the Mississippi River Delta.
Scientists at Brown University use sediment cores not only to gauge past climate but also to see how shifts affected the biodiversity of cichlid fish.
An effort led by a consortium of Lake Erie researchers answers long-standing questions to the issue of phosphorus in Lake Erie sediments and its effect on algal blooms.
Researchers at Keene State College are investigating the effects of dam removal on downstream sediment deposition, according to a release. Their work is taking place on the Nissitissit River in Massachusetts where the Millie Turner Dam was...
Five new papers from the USGS and others reveal the effects of the largest dam removal in U.S. history, including a 10 million cubic meter sediment release
Trying out experimental new techniques and technology, European researchers measured oxygen exchange rates at the sandy bottom of the North Sea.
A new study suggests that evolution was slowed due to low oxygen levels more than a billion years ago, according to a BBC news report. The idea has been around for years, and the researchers put it...
