LAWRENCE—The Kansas Geological Survey at the University of Kansas has been awarded a $650,000 grant from the company XRI Geophysics to improve on technologies used to detect underground voids and faults, to determine the fitness of earthen dams and levees, and in other endeavors.

“With this funding we will continue to advance seismic-imaging technologies conceived and developed at the KGS since the late 1990s,” said Rick Miller, KGS senior scientist and geophysicist.

XRI, headquartered in Vicksburg, Miss., is a private geoscience company that provides services and support to industry and governmental entities for research and advancements related to near-surface geophysics, geology, hydrology and energy resources.

Geophysics researchers at the KGS study the physical properties of the earth, including its electrical, gravitational, magnetic, radioactive and seismic characteristics. The grant will fund further development of noninvasive, high-resolution seismic methods used to characterize rocks and structures in the shallow subsurface — down to about 300 feet deep.

Using seismic-characterization technologies, sound waves are created and measured as they travel through or around underground structures and sediments. Because sound waves travel through different rock types, sediments and fluids in distinct ways, the measurements can be used to interpret various rock conditions and properties.

Seismic characterization has a number of applications in engineering, construction, archeological studies, groundwater investigations, public safety and the identification of such hazards as abandoned mines, caves, fractures and voids that could lead to sinkholes.

Although seismic reflection has been used for several decades, commonly in oil and gas exploration, the KGS has made technological breakthroughs in the past 10 years that overcome limitations of traditional imaging tools used in the shallow subsurface.

“Our objective is to further improve operational efficiency, location and property measurement accuracy, and confidence as well as reduce false positive anomaly detections and allow for near real-time results,” Miller said.

The KGS researchers use a specially outfitted, self-contained vehicle that incorporates an active sound energy source, towed sensors, and a recording and analysis capability.

Poet offers insights to Jayhawk experience through wordplay "Welcome to KU. Where questions rest, in stacks of answers from the past. …" Listen to Topher Enneking, a spoken word poet and former KU football player, as he weaves the experience of KU and its traditions through this storytelling and wordplay performance. Learn more about KU traditions at http://www.ku.edu/about/traditions/. Welcome to KU. Where questions rest in stacks of answers from the past. Where dreams crawl out of bed And learn to walk Uphill both ways. Where freshmen stand on stilts And hang from the rafters, While the wheat waves In a fieldhouse Where the Phog rolls in Helping us to see Through the past into the future. Haunting hosts giving handouts in a heritage Too heavy to grasp til you add to it. So it may be born anew, Allowing our boots to stand in the ash of oppression’s hate But shine bright as the sun While war cries of warriors past Ring in our ears long after their battles are won. Memorials telling time, “you don’t have to stand still.” Because the top of the world Is just up that Hill. Where our natural history is an awe-struck echo Of world’s fair and equal Past, present and future, prelude and sequel. Where our flags fly above planes. Where we build in chalks that can’t be erased. Stone edifices made to last So you would walk Past their doors, down their halls And let your voice fill their room. Because only in empty silence can destruction loom. So stand tall. Wrap your arms around this crowd Sing our alma mater and sing it out loud. Let your voice sing in chorus and reach other nations Beckoning new Jayhawks to spark new collaborations Because you are the mortar that will hold these walls upright. Your future Your dreams are why Jayhawks did fight For the tradition before you Was merely prelude For what will come next now that you’re at KU.
