Nitrogen and phosphorus are essential nutrients—yet too much of a good thing is not always a good thing. Scientists are investigating nutrient pollution down the Mississippi River.
Bogoslof volcano, located in the Aleutian Islands about 98 km (61 mi) northwest of Dutch Harbor/Unalaska, is in an active eruption sequence that began in mid-December 2016 and continues today.
New USGS maps identify potential ground-shaking hazards in 2017 from both human-induced and natural earthquakes in the central and eastern U.S.
It is difficult to overstate the importance of energy to the American economy. Managing this vital sector depends on knowing how many energy resources we have, how many we use and need, and how these resources are transported.
Get your flip-flops and shorts out because spring is arriving very early this year . . . at least 2-3 weeks early across almost the entire Southeast, from San Antonio to Atlanta to Washington, D.C. This unusually early spring is likely to keep rolling north, already bringing surprising signs of spring to portions of the central Midwest and northeastern states.
Atmospheric rivers are a global weather phenomenon that can bring large amounts of rain or snow to the U.S. West Coast each year. These rivers of wet air form over the Pacific Ocean near Hawaiʻi and pick up large amounts of moisture from the tropics and on their way to the West Coast. This moisture is carried in narrow bands across the Pacific Ocean to California, Oregon, Washington and Nevada.
When wildfires spread and scorch the earth, people like Penny Luehring have to act fast. Secondary impacts such as debris flows can be devastating to nearby communities.
“We’re seeing the loss of forests in many places,” said Matthew Hansen, a professor at the University of Maryland. “Dynamics include increasing tropical deforestation, more frequent and severe boreal forest fires, disease in temperate forests and the commoditization of subtropical forests.”
The topic, officially, was water. But during a scientific conference in Butte, Montana, in 2013, earthquake expert Michael Stickney glimpsed something unexpected in a three-dimensional lidar image of the Bitterroot Valley in nearby Missoula.
The U.S. Geological Survey is near the midpoint of a complex undertaking to survey the quality of the nation’s largest drinking-water resource. From 2012 – 2023, the USGS is assessing groundwater throughout the country through extensive sampling. The latest results from five regional aquifers have become available today.
Hundreds of articles have been written about the largest volcanic eruption in recorded history, at Indonesia’s Mt. Tambora just over 200 years ago. But for a small group of New England-based researchers, one more Tambora story needed to be told, one related to its catastrophic effects in the Gulf of Maine that may carry lessons for intertwined human-natural systems facing climate change today.
Richard Batiuk got to know the Chesapeake Bay in the early 1970s. During visits with his friends and family, they would swim and boat, and fish would practically jump aboard. He was young but knew he wanted to live and work on the bay.
