Necessary resources such as oil and water lie below our feet. Research scientist Chris Zahm of the Bureau of Economic Geology talked to EarthSky about how today’s scientists are coming to understand the world underground, while exploring for resources in safe, practical and effective ways.

Nanotechnology – that is, working with matter at the scale of atoms and molecules – shows great promise for meeting challenges involved in understanding and utilizing the harder-to-reach oil and gas reservoirs of today. That’s according to scientists at the Advanced Energy Consortium (AEC), a research organization that develops micro- and nano-sensors to transform understanding of subsurface oil and natural gas reservoirs. The University of Texas at Austin’s Bureau of Economic Geology at the Jackson School of Geosciences manages the AEC. Two AEC scientists, Jay Kipper and Sean Murphy, spoke with EarthSky about how the success of nanomaterials in diverse fields such as medicine and automotives is being applied to petroleum science.

Michael Young on water resources in Texas

By in Earth | Mar 14, 2013

Severe drought in 2011 and 2012 in Texas raises questions about the present and future of the state’s water resources. Scientists expect groundwater supplies in Texas to fall by 30 percent by 2060. Scientist Michael Young of the Bureau of Economic Geology, Jackson School of Geosciences, University of Texas at Austin talked to EarthSky about what scientists know about water resources in Texas.

Jeffrey Paine: Retreating shoreline along Texas Gulf coast

By in Earth | Jan 21, 2013

The Texas Gulf coast is among the most dynamic environments on Earth. Jeffrey Paine talks about the retreating coastline, and the risks and value of human activity there.

Hydraulic fracturing, commonly known as fracking, is used to extract shale gas by injecting fluids into the ground to drill and frack a well. This method of obtaining energy has raised environmental concerns and is challenging some existing regulatory regimes. What does the science say? Geoscientist Ian Duncan is a research scientist at the Bureau of Economic Geology at the University of Texas at Austin. His current research focuses on the scientific, environmental and public policy aspects of hydraulic fracturing. He talked to EarthSky about what the science says so far about fracking’s environmental impact.

Kathryn Reese-Taylor on the Mayan calendar and 2012 doomsday prophesies

By in Human World | Dec 07, 2012

Doomsday and 2012. You’ve probably heard rumblings, if not more, about a supposed connection. Many people point to an ancient Mayan calendar – made 1200 years ago – as the source of the rumors. EarthSky spoke with Kathryn Reese-Taylor, professor of Mayan archaeology at the Canada’s University of Calgary about what archaeology says about 2012 and doomsday prophecies.

Lesli Wood: Exploring Gulf of Mexico deep water oil

By in Earth | Nov 30, 2012

To meet demand for oil, industry has pushed the limits of technology to reach new oil reserves. In the deep water of the Gulf of Mexico, some estimates say there is enough oil to power the United States for 10 years or more. Geoscientist Lesli Wood is a Senior Research Scientist with the Bureau of Economic Geology at the University of Texas at Austin. Dr. Wood talked with EarthSky about the current challenges and future innovations involved in exploring for oil in the deep waters of the Gulf of Mexico.

Blue color represents the marine waters with darker colors representing deeper water (>200 meters). Of the 1300 offshore US fields in the Gulf of Mexico, the top 20 producers are now all in deep waters.

David Stuart on the Mayan calendar and 2012 doomsday predictions

By in Human World | Nov 23, 2012

The ancient Maya of Central America and Southern Mexico are famous for perfecting a calendar to which many attribute predictions that the world will end on December 21, 2012. EarthSky spoke with Professor David Stuart, an archaeologist and expert on the ancient Maya at the University of Texas at Austin. He told us that neither the Maya, nor their calendar, ever predicted the end of the world.

Tim Lowenstein on a world of microbes buried alive in ancient salt

By in Earth | Oct 26, 2012

Lowenstein studies water droplets that have been sealed inside salt crystals for thousands to millions of years. His team is the first to try to paint a complete picture of what’s living in these drops of water.

Earth’s human population has reached 7 billion and is still climbing. Scientists say the depletion of groundwater around the world is a serious issue. They say we need to know where our water resources are, and what options society can leverage to use these resources most effectively. Bridget Scanlon is a Senior Research Scientist at the Bureau of Economic Geology at the University of Texas at Austin. Her research team works to assess water resources and offer sustainable solutions. She spoke with EarthSky’s Jorge Salazar.

You say there’s a hidden cost of water in everything we use and consume. Tell us about that.

That’s right. When you ask them how much water they use, a lot of people think of the household usage for laundry and showering and things like that. But our food choices involve a lot more water.
