Radio Netherlands covers Louis Jacobs’ research in Angola

Radio Netherlands Worldwide covered the research in Angola of SMU paleontologist Louis L. Jacobs.

Journalist Lula Ahrens writes about Projecto PaleoAngola in the Aug. 15 article “Angola key to understanding Earth history.”

A professor in Dedman College‘s Roy M. Huffington Department of Earth Sciences, Jacobs joined SMU’s faculty in 1983.

Currently he has projects in Mongolia and Angola. His book, “Lone Star Dinosaurs” (1999, Texas A&M University Press) was the basis of an exhibit at the Fort Worth Museum of Science and History that traveled the state. He consulted on the new exhibit, Mysteries of the Texas Dinosaurs, which opened in 2009.

In the laboratory, Jacobs’ research utilizes advanced imaging and stable isotope techniques to investigate paleoenvironmental, biogeographic and phylogenetic issues of the Mesozoic and Cenozoic eras.

Angola is famous for its oil and diamond wealth. But it is also a ‘last frontier’ for another, less noted treasure: a mindboggling number of prehistoric fossils.

Dozens of mosasaurs, dinosaurs, plesiosaurs, pterosaurs and turtles are excavated over one month each year by a small, international team of paleontologists (PaleoAngola). According to them, “Angola is the key to understanding the Atlantic rift which separated South America from Africa.”

“The ‘Big Five’ with the most prehistoric fossils are the US, Canada, Mongolia, China and Argentina,” Dr. Octavio Mateus from the New University of Lisbon pointed out during dinner at a Chinese restaurant in Angola’s capital Luanda with PaleoAngola and its sponsors.

“In Portugal, seventh on the list, I find a piece of a skull once every two years. Here, three a day! “Since 2005, in the South of Angola the group has discovered roughly ten species of mosasaurs, plesiosaurs, dinosaurs, pterosaurs and turtles,” said Mateus.

He uncovered the bones of a sauropod dinosaur north of Luanda in 2005. “We don’t know any other place on earth as rich as this one in vertebrates,” he said. “Paleontologists will have plenty work in Angola for generations to come.”

The exact location of the findings is a secret. Professor Louis Jacobs from the Southern Methodist University in the US: “You have to make sure nothing ends up in the wrong hands.”

SMU Geothermal Lab and DOE host Wyoming geothermal conference

800px-Geothermal_energy_methods.pngThe U.S. Department of Energy’s Rocky Mountain Oilfield Testing Center, RMOTC, in partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory, NREL, and Southern Methodist University Geothermal Laboratory, hosted a two-day “Geothermal in the Oil Field” symposium in Casper, Wyo., Aug. 18-19, 2010.

The event highlighted the application of low-temperature geothermal power production in oil and gas operations and other settings in the western United States.

This first-of-its-kind symposium provided valuable information on this emerging domestic power source. Speakers covered low-temperature projects throughout the western U.S. and provided participants an opportunity to learn about the remarkable potential for power generation using co-produced fluids from existing oil, gas, and industrial infrastructure with minimal additional environmental impacts.

On Day 1, RMOTC hosted field tours of nearby formations at Alcova Reservoir that correlate to the producing formations at NPR-3 and the test site located at the Naval Petroleum Reserve No. 3 (NPR-3) 35 miles north of Casper, Wyoming.

Day 2 was a day of technical presentations and panel discussions by DOE and industry representatives.

AGI’s Earth magazine covers SMU seismic research in Barnett Shale region

Thumbnail.jpg

Earth magazine’s Carolyn Gramling interviewed SMU geophysicist Brian Stump about the operation of a saltwater injection disposal well that was a “plausible cause” for a series of small earthquakes in the Dallas-Fort Worth area in 2008.

The May 13 article in Earth, the magazine of The American Geological Institute, explores the research into the earthquakes, which occurred in an area of North Texas where the vast Barnett Shale geological formation traps natural gas deposits in subsurface rock.

Natural gas production in the Barnett Shale relies on the injection of pressurized water into the ground to crack open the gas-bearing rock, a process known as “hydraulic fracturing.”

Some of the injected water is recovered with the produced gas in the form of waste fluids that require disposal. Research by Stump looked at incidents that occurred in an area of North Texas where the vast Barnett Shale geological formation traps natural gas deposits in subsurface rock.

A saltwater disposal well, a part of the natural gas production process, may have been responsible for triggering a series of minor earthquakes in the Dallas-Fort Worth area of Texas in 2008, according to a recent study.

A series of small earthquakes that shook up the Dallas-Fort Worth area may be linked to natural gas production in the nearby Barnett Shale.

From Oct. 31 to Nov. 1, 2008, several minor earthquakes rattled the walls and shook the furniture of numerous residences in the Dallas-Fort Worth area.

The earthquakes, with magnitudes between 2.5 and 3.0, prompted questions among the residents about whether drilling for natural gas in the nearby Barnett Shale was responsible for the shaking. A second series of earthquakes, with the largest a magnitude 3.3, occurred on May 16, 2009; a third occurred on June 2, 2009.

Natural gas production involves multiple steps, including drilling a natural gas well, pumping pressurized fluids into the well to crack open the rock (hydraulic fracturing), and then extracting the natural gas and used fluids.

Once the gas and fluids are extracted, the fluids are reinjected back into the ground via a different well, called a saltwater disposal well, located some distance away from the production wells.

National Geographic: Texas pterosaur Aetodactylus Halli in the spotlight after 95 million years

National Geographic News interviewed SMU postdoctoral researcher Timothy S. Myers about the new species and genus of pterosaur he identified and named, Aetodactylus Halli.

In the April 28 article “Toothy Texas Pterosaur Found; Soared Over Dallas” reporter John Roach talked to Myers about the 95 million-year-old jaw that was discovered by Lake Worth resident Lance Hall.

The pterosaur flew over the ancient sea that used to cover much of the Dallas-Fort Worth area. A rare species of pterosaur in North America, Myers named the new flying reptile after Hall.

Others who wrote about Myers’ Aetodactylus Halli research include:

Others who published a story about the find were: American Scientist, MSNBC, FOX News, the San Diego Tribune and many others.

Long before six flags flew over Texas, a newfound species of winged reptile
with an exceptionally toothy grin owned the skies over what is now the Lone
Star State.

The recently discovered pterosaur, dubbed Aetodactylus halli, was identified based on a 95-million-year-old lower jawbone found outside of Dallas by amateur fossil hunter Lance Hall.

The pterosaur had a relatively slender jaw filled with thin, needlelike teeth, which might have helped the creature pluck fish from the shallow sea that once covered the region, a new study says.

“It was hanging out near the ocean, and that is probably where it derived its food from,” said study leader Timothy Myers, a paleontologist at Southern Methodist University in Dallas.

By comparing the jawbone to more complete pterosaur fossils, Myers and his team think A. halli was a medium-size animal with a nine-foot (three-meter) wingspan and a short tail.

Texas’s Toothy Pterosaur a Rare Find
Pterosaurs ruled the skies from the late Triassic period, more than 200 million years ago, until dinosaurs went extinct at the end of the Cretaceous, about 65 million years ago.

Guam TV: USGS-SMU project monitors Anatahan volcano

Anatahan volcano

News reporter Tina Chau of Guam News Watch television interviewed SMU vulcanologist James Quick about the danger of nearby Anatahan volcano to neighboring Guam. Quick leads a two-year, $250,000 volcano monitoring project of the U.S. Geological Survey and Southern Methodist University in the Northern Mariana Islands.

The project, which includes Anatahan volcano, will use infrasound — in addition to more conventional seismic monitoring — to “listen” for signs that a volcano is about to blow. The plan is to beef up monitoring of lava and ash hazards in the Marianas, a U.S. commonwealth near Guam. The island of Guam soon will be the primary base for forward deployment of U.S. military forces in the Western Pacific.

The USGS-SMU team recently installed equipment on the islands that was originally designed to detect nuclear explosions and enforce the world’s nuclear test-ban treaty, an area of expertise for <a href=”https://blog.smu.edu/research/2006/06/brian_stump.html#more” target=”blank”>SMU scientists</a>. The Marianas’ project is an effort to pioneer the use of the technology to monitor active volcanoes.
