Protect Your Groundwater Day on September 8, 2015

National Ground Water Association

The National Ground Water Association (NGWA) celebrates Protect Your Groundwater Day on September 8, 2015, promoting water conservation and contamination prevention as ways to protect groundwater resources.

"Every person can do something to protect local groundwater, from not polluting it to using water wisely," says NGWA Public Awareness Director Cliff Treyens. "The good news is that for most people all it takes is a small adjustment in their daily habits."

PolarTREC

Applicaiton deadline: September 8, 2015

PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program in which K-12 teachers spend 3-6 weeks participating in hands-on field research experiences in the polar regions. The goal of PolarTREC is to invigorate polar science education and understanding by bringing K-12 educators and polar researchers together. By fostering the integration of research and education, PolarTREC will continue the momentum established during the International Polar Year (IPY) by addressing the following program objectives:

PAESTA Podcast Series: Episode 2 - What is the Difference Between Paleontology, Archaeology, and Anthropology?

You Asked, We Answered!

Transcript for the podcast

These career fields are front and center in pop culture, thanks to Hollywood blockbuster films, such as the Jurassic Park and Indiana Jones series. Unfortunately, popular culture can sometimes blur the boundaries and misrepresent these disciplines. This podcast explores the differences between the three fields of paleontology, anthropology, and archaeology.

Where does water go when it doesn't flow?

NSF

From NSF, 07/09/2015  -- More than a quarter of the rain and snow that falls on continents reaches the oceans as runoff. Where does the rest go? Now results of a new study help answer that question: two-thirds of the remaining water comes from plants, more than a quarter lands on leaves and evaporates, and what's left evaporates from soil and from lakes, rivers and streams.

EARTH Magazine: Studies Re-examine How Major Copper Deposits Form

EARTH Magazine

From EARTH Magazine, 06/24/2015  --  Humans depend on copper for everything from electrical wiring to water pipes. To meet demand, the metal has been largely mined from Porphyry Copper Deposits (PCDs). For decades, scientists generally agreed upon the geological processes behind PCD formation; now EARTH Magazine examines two new studies that suggest alternatives to these long-held understandings.
