CU Boulder FACULTY LEAD $7 MILLION INITIATIVE AIMED AT MILITARY VEHICLE SAFETY
Aug 11th
Aug. 11, 2011
University of Colorado Boulder engineering faculty are leading a $7.2 million multidisciplinary research initiative on soil blast modeling and simulation for the U.S. Department of Defense.
The research, which starts this month, is aimed at creating a more accurate representation of the impact of buried landmines and improvised explosive devices, or IEDs, on light-armored military vehicles so that the vehicles can be better designed to withstand such blasts.
The award is administered by the Office of Naval Research as part of the defense department’s competitive Multi-University Research Initiative or MURI program, which supports basic science and engineering research at U.S.universities related to long-term national security needs.
MURI awards are provided to accelerate progress in cutting-edge research areas by supporting multidisciplinary teams with larger and longer awards than other DOD research programs.
The grant will provide $4.2 million to CU-Boulder and $3 million to co-investigators at four other institutions. The other schools involved are the University of California, Berkeley; University of Texas at Dallas; University of Tennessee Knoxville; and the University of Utah.
Richard Regueiro, assistant professor in CU-Boulder’s Department of Civil, Environmental and Architectural Engineering, is the principal investigator. CU-Boulder professors Ronald Pak, John McCartney and Stein Sture of civil engineering, and Oleg Vasilyev of mechanical engineering, also areinvolved.
The research initiative will involve experiments using CU-Boulder’s large 400-g ton geotechnical centrifuge coupled with computational modeling. The objective is to develop and validate a model that accurately represents explosive blasts of varying charges, depths and soil types.
CU-Boulder’s proposal was one of 27 MURI awards made to academic institutions in different topical areas in 2011. The proposals, which are being funded with a total of $191 million over five years, were selected from a field of 332 proposals, including 17 on the topic of soil blast modeling and simulation.
Longmont-to-Boulder Regional Trail opening July 14
Jul 7th
Boulder County, Colo. – The Boulder County Transportation and Parks and Open Space departments, along with the City of Longmont, will open the north segment of the Longmont-to-Boulder Regional Trail on Thursday, July 14.
The trail segment is nearly three miles long and stretches from the Lefthand Valley Grange Trailhead on North 83rd Street to the North 95th Street bridge at Lefthand Creek in Longmont. Trail segment map.
“We are very excited about the completion of this section of the LoBo trail because it provides a long-awaited off-street alternative between Gunbarrel, Niwot and Longmont,” said Kristine Obendorf, Boulder County’s Regional Trails Planner.
A public ribbon-cutting ceremony with officials from Boulder County and Longmont will take place on July 14 at 4:30 p.m. at the Lefthand Valley Grange Trailhead near the corner of 83rd Street and Niwot Road.
Group bike rides from Longmont and Boulder that will meet at the Lefthand Valley Grange Trailhead for the ribbon-cutting ceremony are being organized. Information about the ride from Longmont is posted online. Contact Sue Prant at bikesue@gmail.com for information about the ride from Boulder.
The new trail crosses Lefthand Creek just north of Oxford Road using a refurbished pedestrian bridge from the City of Boulder that was part of a three-way bridge swap among Boulder County and the cities of Longmont and Boulder.
“We are happy about the partnership with Boulder County as we were able to replace a functionally obsolete bridge and replace it with a new structure that meets all current standards and allows for a trail underpass,” City of Longmont Project Manager Tom Street said.
The joint project between Boulder County and the City of Longmont includes both the bridge and trail connection and was funded by Longmont, a federal transportation grant awarded to Boulder County in 2007, and the countywide transportation sales tax approved by voters in 2001.
The majority of the land provided for the trail is either within county road right-of-way or is on county open space property purchased with Parks and Open Space sales tax funds.
The project comprises the northern most section of the planned 12-mile Longmont-to-Boulder Regional Trail that begins on the City of Boulder’s Cottonwood Trail and terminates at the Lefthand Greenway in Longmont. The LoBo Trail is primarily a soft-surface path that provides a continuous off-road link along the Diagonal Highway corridor.
Missing links at Jay Road and Lookout Road are in the planning phases as is a new connection to the Boulder Reservoir underneath the Diagonal Highway. Please visit the Boulder County Regional Trails Program webpage for more information.
NSF AWARDS CU-BOULDER $5.9 MILLION GRANT FOR ALPINE ECOSYSTEM RESEARCH
Jun 16th
The National Science Foundation has awarded the University of Colorado Boulder a six-year, $5.9 million grant to continue intensive studies of long-term ecological changes in Colorado’s high mountains, both natural and human-caused, over decades and centuries.
Awarded to CU-Boulder’s Institute of Arctic and Alpine Research, the renewal grant will allow faculty and students, including undergraduates, to continue key environmental studies at the Niwot Ridge Long-Term Ecological Research, or LTER, site west of Boulder. The study site, considered extremely sensitive to climate change, is adjacent to CU-Boulder’s Mountain Research Station and encompasses several thousand acres of tundra, talus slopes, glacial lakes and wetlands stretching to the top of the Continental Divide.
The grant is the largest environmental sciences award in CU-Boulder history, said INSTAAR Fellow Mark Williams, principal investigator on the grant. In 2005, NSF awarded CU-Boulder a $4.9 million renewal grant for environmental studies at the Niwot Ridge site. As one of five initial LTER sites selected by NSF in 1980, Niwot Ridge is now one of 25 such sites in North America and the only one located in an alpine environment, said Williams.
“CU-Boulder has a worldwide reputation for monitoring global climate change from Greenland to Antarctica and its impacts on natural ecosystems and human populations,” said Vice Chancellor for Research Stein Sture. “To direct such a key program in our own backyard for the National Science Foundation is crucial from an environmental science standpoint and unique in that it provides a spectacular training ground for our students to work side-by-side with some of the world’s best climate change scientists.”
Recent climate studies have predicted the mountainous areas of the American West will become both hotter and drier in the coming years, and long-term meteorological measurements on Niwot Ridge indicate the alpine climate there has warmed slightly in recent decades, said Williams, also a professor in the geography department. The temperatures are significant because even small changes in alpine ecosystems can cascade down and have negative effects on other ecosystems, he said.
CU-Boulder researchers also have charted a doubling in atmospheric nitrogen deposition on Niwot Ridge in the past several decades — primarily from automobile, agriculture, ranching and industrial activity — that is now adversely affecting some aquatic and terrestrial life on the ridge, said Williams.
In addition, researchers are keeping a close eye on existing populations of the American pika, a potato-sized animal related to rabbits and found in rocky talus slopes as high as 13,000 feet on Niwot Ridge. Of 25 populations of pikas in the Great Basin of Nevada documented between 1898 to 1990, nine had disappeared by 2008, apparently the result of warming temperatures. Pikas in Colorado require deep snowpack during winter that serves to insulate them from extremely cold air temperatures, Williams said.
“Many consider the American pika a ‘sentinel species’ in terms of measuring the effects of climate change,” said Williams. “Niwot Ridge has a cold, short growing season, and the biological activity that occurs there is on the razor’s edge of environmental tolerance.”
Despite a long-term warming and drying trend in mountainous areas of the West, 2011 was a striking anomaly, said Williams. “What we have seen around here is one of the largest and latest snowfall years on record in the high country and extreme dryness accompanied by an inordinate amount of winter wildfires around Boulder, which is only 15 miles as the crow flies from the Niwot Ridge study area. What has happened from Boulder west to the Continental Divide has been a total disconnect in terms of weather.”
“The primary climate driver of the Niwot Ridge site is snow, and the mountains are our water towers,” said Williams. “As the alpine climate changes, one of the biggest impacts on humans will be a change in water resources. Even if we end up with the same amount of precipitation, in the form of less snow and more rain, we are going to end up with less usable water for municipalities.”
There already are some indications that the snowline in the Rocky Mountains is moving upward, which will affect the abundance and distribution of plants and animals and likely shorten the annual ski seasons at resorts throughout the West in the future, he said.
The Niwot Ridge site is a huge benefit to CU-Boulder students, said Williams. “I have five undergraduates working in my chemistry lab this summer. Not only do they get paid, but they learn valuable research skills.” The LTER grant funds research for about 15 CU-Boulder graduate students and 25 to 30 undergraduates annually, Williams said, and there are more than a dozen CU-Boulder faculty members that are co-investigators on the new Niwot Ridge LTER program grant.
CU-Boulder ecology and environmental biology department Professor William Bowman, director of CU-Boulder’s Mountain Research Station for the past 20 years, said the Niwot Ridge site has been gaining momentum in stature from its beginnings by the consistent, high-quality research that has resulted in many publications in top-tier science journals.
More than half of the research on Niwot Ridge is by scientists and students from around the world that are not associated with the LTER program, said Bowman, also an INSTAAR fellow and who leads a team studying how air pollution, including nitrogen deposition, threatens biological and aquatic communities in U.S. national parks. There are currently 12 undergraduates conducting research at the Niwot Ridge site as part of the NSF’s Research Experience for Undergraduates program, said Bowman, who also is mentoring a student researcher at Niwot Ridge from Fairview High School in Boulder.
