How much water flows into agricultural irrigation? New study provides 18-year water use record

Thu, 10/19/2017 - 10:00

Irrigation for agriculture is the largest use of fresh water around the globe, but precise records and maps of when and where water is applied by farmers are difficult to locate. Now a team of researchers has discovered how to track water used in agriculture.

In a paper published in the journal Geophysical Research Letters, the researchers detail their use of satellite images to produce annual maps of irrigation. The findings, the scientists said, will help farmers, water ...

A fresh look at fresh water: Researchers create a 50,000-lake database

Thu, 10/19/2017 - 10:00

Countless numbers of vacationers spent this summer enjoying lakes for swimming, fishing and boating. But are they loving these lakes to death?

The water quality of the nation's lakes is threatened not only by the things people do in and around them, but, say scientists, by less obvious factors such as agriculture and changes in climate. Because lakes are as distinct as one snowflake from another, they may respond differently to these challenges.

To better understand the ...

LIGO: Einstein Was Right

Mon, 10/16/2017 - 10:43

A century ago, Albert Einstein predicted gravitational waves -- ripples in the fabric of space-time that result from the universe's most violent phenomena. A hundred years later, NSF-funded researchers using the Laser Interferometer Gravitational-wave Observatory (LIGO) have detected gravitational waves.

LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars

Mon, 10/16/2017 - 10:34

Watch the Press Conference live at the https://www.youtube.com/c/VideosatNSF/live website.

For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been observed in both gravitational waves and light.

The discovery was ...

Fossil discovery in Tanzania reveals ancient bobcat-sized carnivore

Wed, 10/11/2017 - 14:00

Paleontologists working in Tanzania have identified a new species of hyaenodont, a type of extinct meat-eating mammal. The study is published today, National Fossil Day, in the journal PLOS ONE and funded by the National Science Foundation (NSF).

After the extinction of the non-avian dinosaurs 66 million years ago, hyaenodonts were the main predators on the African continent. The newly discovered animal is called Pakakali rukwaensis, the name derived from the ...

EarthScope's Transportable Array now spans Alaska, the last frontier

Wed, 10/11/2017 - 08:51

Seismic station A19K, it’s called, and it’s now at the edge of an abandoned airstrip far above the Arctic Circle. The nearest population center is 127 miles northeast in Utqiaġvik (formerly known as Barrow), the northernmost city in the United States. What a way to celebrate Earth Science Week, Oct. 8-14, 2017.

The seismic station is part of EarthScope, a project funded by the National Science Foundation (NSF). It's one of hundreds of stations collectively called the ...
