CU Boulder invites public to Nov. 26 workshop on oil and gas development on groundwater
Nov 19th
The workshop, titled “Monitoring and Protecting Groundwater during Oil and Gas Development,” will focus on oil and gas development procedures that can impact groundwater, the current state regulations that protect groundwater, the changes proposed by the commission, and other recommendations. The commission will hold a second hearing and plans to finalize new regulations on Dec. 10, 2012.
The workshop is free and open to the public and is co-sponsored by the CU-Boulder Natural Resources Law Center’s Intermountain Oil and Gas Best Management Practices Project and the Colorado Water and Energy Research Center.
The Oil and Gas Conservation Commission of the state of Colorado has required water well sampling and monitoring for many years through numerous state orders, rules and conditions of approval. The proposed water-sampling rule would establish sampling and monitoring requirements on a statewide basis and would eventually supersede other commission water sampling rules and orders, with the exception of rules concerning sampling in coal-bed methane areas.
The sampling rule is intended to provide the commission with a mechanism to obtain data consistently across the state. These data are intended to help verify that water wells, ground and surface waters, and residents of producing basins are adequately protected and that impacts, should they occur, are quickly identified and mitigated.
“Energy, jobs and a clean environment, including clean and sufficient groundwater, are extremely important to Colorado today and for our future,” said Kathryn Mutz, Natural Resources Law Center senior research associate and Intermountain Oil and Gas Best Management Practices Project manager. “Ensuring groundwater protection during oil and gas development is one important part of the puzzle. This workshop is providing a venue outside of the formal commission rulemaking process to discuss and educate ourselves and the stakeholders about the alternatives so that we get this rule right for Colorado.”

The Intermountain Oil and Gas Best Management Practices Project website and database are maintained as part of the Natural Resources Law Center within the CU-Boulder Law School. Best Management Practices are mitigation measures applied to areas being developed for oil and gas to promote energy development in an environmentally sensitive manner. The project is supported, in part, by the Environmentally Friendly Drilling Project and a CU-Boulder Outreach Award.
The Colorado Water and Energy Research Center, led by Mark Williams, CU-Boulder professor of geography, provides a neutral clearinghouse for information on the potential hydrologic impacts of natural gas development.

CU :$20 million instrument package set for integration on Mars spacecraft
Nov 19th
The remote sensing package designed and built by CU-Boulder’s Laboratory for Atmospheric and Space Physics consists of the Imaging UltraViolet Spectrograph, or IUVS, as well as its electronic control box, the Remote Sensing Data Processing Unit, or RSDPU, both under contract to NASA Goddard Spaceflight Center in Greenbelt, Md.
Known as the Mars Atmosphere and Volatile EvolutioN, or MAVEN, the $670 million NASA mission set for launch in November 2013 is being led by CU-Boulder Professor Bruce Jakosky. The mission is designed to explore and understand how the loss of atmospheric gas has changed the climate of Mars over the eons, said Jakosky, also associate director of LASP.
“With the delivery of this package, we are shifting from assembling the basic spacecraft to focusing on getting the science instruments onto the spacecraft,” said Jakosky, also a professor in the geological sciences department. “This is a major step toward getting us to launch and then getting the science return from the mission.”
According to David Mitchell, MAVEN project manager from NASA Goddard, “The remote sensing package team built a system that meets all technical requirements and delivered it on schedule and on budget. I look forward to the instrument’s next level of integration onto the spacecraft and ultimately the science it will provide.”
The IUVS collects UV light and spreads it out on a spectra that is recorded using imaging detectors, said Mitchell. As the “brains” of the instrument package, RSDPU receives and executes commands telling the IUVS when and where to point.
“As the ‘eyes’ of the remote sensing package, the IUVS allows us to study Mars and its atmosphere at a distance by looking at the light it emits,” said Nick Schneider, a LASP research associate and lead IUVS scientist for MAVEN. “Ultraviolet light is especially diagnostic of the state of the atmosphere, so our instrument provides the global context of the whole atmosphere for the local measurements made by the rest of the payload,” said Schneider, also a faculty member in the APS department.
The CU-Boulder remote sensing package will be turned on for its initial checkout 21 days after launch, said NASA officials. Later, in the “cruise phase” of the mission from Earth to Mars, the package will be powered on twice more for “state-of-health checks” and in-flight calibration.
MAVEN will be the first mission devoted to understanding the Martian atmosphere, with a goal of determining the history of the loss of atmospheric gases to space through time, providing answers about Mars climate evolution. By measuring the current rate of gas escaping to space and gathering enough information about the relevant processes, scientists should be able to infer how the planet’s atmosphere evolved over time.
The MAVEN spacecraft will carry two other instrument suites. The Particles and Fields Package, built by the University of California Berkeley Space Science Laboratory with support from LASP and NASA Goddard, contains six instruments that will characterize the solar wind and the ionosphere of the planet. The Neutral Gas and Ion Mass Spectrometer, provided by NASA Goddard, will measure the composition and isotopes of neutral ions.
“Three of the big milestones in an instrument builder’s life are the day you get selected to fly on a mission, the day you deliver the instrument to the spacecraft to get ready for launch, and the day that it gets where it’s going and data starts flowing back from space,” said Mark Lankton, the remote sensing package program manager at LASP. “The remote sensing team is really happy to have gotten to the second milestone, and we can hardly wait to reach the third.”
CU-Boulder also will provide science operations and lead the education and public outreach efforts. NASA Goddard manages the project and is building two of the science instruments for the mission. Lockheed Martin is building the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., provides navigation support, the Deep Space Network, the Electra telecommunications relay hardware and operations.
“Our CU-Boulder IUVS instrument will be the most capable ultraviolet spectrometer ever sent to another planet,” said LASP instrument scientist William McClintock. “Data from the IUVS will help planetary scientists rewrite the textbooks about the upper atmosphere of Mars, and we are fortunate to have a top-flight engineering team here at LASP that allowed us to design and develop such a sophisticated instrument.”
Clues on the Martian surface, including features resembling dry lakes and riverbeds as well as minerals that form only in the presence of water, suggest that Mars once had a denser atmosphere that supported liquid water on the surface, Jakosky said. CU-Boulder’s participation in Mars exploration missions goes back to 1969 when NASA’s Mariner 6 and Mariner 7 missions launched.
MAVEN is slated to slide into orbit around Mars in September 2014, and, after a one-month checkout period, will make measurements from orbit for one Earth year. The MAVEN science team includes three LASP scientists from CU-Boulder heading instrument teams — Schneider, Frank Eparvier and Robert Ergun — as well as a large supporting team of scientists, engineers and mission operations specialists.
MAVEN also will include participation by a number of CU-Boulder graduate and undergraduate students in the coming years. Currently there are more than 100 undergraduate and graduate students working on research projects at LASP, which provides hands-on training for future careers as engineers and scientists, said Jakosky.
CU project: Degraded military lands to get ecological boost
Nov 15th
Headed up by CU-Boulder Assistant Professor Nichole Barger, the research team is focused on developing methods to restore biological soil crusts — microbial communities primarily concentrated on soil surfaces critical to decreasing erosion and increasing water retention and soil fertility. Such biological soil crusts, known as “biocrusts,” can cover up to 70 percent of the ground in some arid ecosystems and are dominated by cyanobacteria, lichens, mosses, fungi and bacteria, she said.
The project is aimed at restoring fragile habitats in desert areas that have been affected by the movement of U.S. military vehicles, including tanks, as well as high foot traffic, said Barger, a faculty member in CU-Boulder’s ecology and environmental biology department. The team has two U.S. Department of Defense study sites — Fort Bliss, which straddles southern Texas and New Mexico and is located in a hot desert environment, and the Dugway Proving Ground in northwest Utah, seated in a cool desert environment.
“Biocrusts often are associated with increased soil nutrients and water retention, but their most important task is to stabilize soil surfaces against wind and water erosion,” Barger said. “While most biocrusts are relatively resilient to wind and water erosion, they are highly susceptible to compressional forces like those generated by foot and vehicle traffic associated with ground-based military activities.”
At military installations like Fort Bliss, the Dugway Proving Ground and in the California/Arizona Maneuver Area in the Mojave Desert used by Patton’s troops, scars of past military activity still are evident, said Barger. “You can go to these places and see that the biocrusts in the old tank tracks, for example, are completely different than nearby biocrusts undisturbed by military activity.”
The project is being funded by a five-year, $2.3 million grant from the Strategic Environmental Research and Development Program, the U.S. Department of Defense environmental science and technology program that partners with the U.S. Department of Energy and the Environmental Protection Agency. The research team also includes Jayne Belnap, Michael Duniway and Sasha Reed from the U.S. Geological Survey’s Biological Resources Division in Moab, Utah and Ferran Garcia-Pichel of Arizona State University in Tempe.
The first step of the program will be to grow biocrusts in laboratories at ASU, said Barger. “Our approach will be to expose laboratory biocrusts over time to a physiological ‘boot camp’ that includes increasing stressors like heat, light and dryness,” she said. “By doing that, we believe the biocrusts we eventually transplant into the study areas will have a higher probability of survival.”
The lab-grown biocrust products will be dried, bagged and transported to field test sites at each respective military installation and sprinkled on soil surfaces, said Barger.
Once in the field, the stress-adapted biocrusts developed in the lab nurseries for both hot desert and cool desert environments will be combined with other soil stabilization strategies, she said. The team, for example, will also experiment with adding polyacrylamide — a soil-stabilizing compound shown to increase soil porosity and reduce erosion, compaction, dustiness and water run-off — to the mix.
The researchers will evaluate the effectiveness of such soil “inoculations” and determine the optimum dosage for the test sites. Following the assisted recovery of the local biocrusts at Fort Bliss and the Dugway Proving Ground, the team will begin a series of seeding trials to develop strategies for native plant re-establishment, Barger said.
The last step of the project will involve a series of rainfall simulations and wind tunnel experiments combined with broad-scale soil erosion modeling to evaluate the influence of biocrust and native plant restoration in terms of precipitation and soil erosion.
While DOD military installations cover nearly 30 million acres — 70 percent of which are located in arid regions of the West — Barger said the research also could aid in the effective management of other federal lands. “We think our work on biocrusts also will be of interest to land managers at agencies like the Bureau of Land Management and the U.S. Forest Service,” Barger said.
The adaptation of biocrusts to extreme environments likely will come into play even more as climate change continues to heat and dry the West, she said. “We expect the drought in the Southwest to intensify as a result of climate change, and this project should tell us more about how adaptive these biocrusts are under shifting environmental conditions.”
The research project also has health implications, said Barger, since the disturbance of biocrusts can trigger the release of significant amounts of atmospheric dust, a dominant pollutant in some desert metropolitan areas. “There is a broad societal interest in stabilizing dryland soils in order to protect not only the functioning of local ecosystems but also human populations that reside in surrounding communities.”
“In terms of tackling an important environmental issue, this is by far the most exciting research project that I have been involved in,” said Barger, who has worked in Hawaii, Central America, South America, China and South Africa.
