TUESDAY, NOVEMBER 18

8:15 – 8:45 AM – U.S. Department of the Interior Management Efforts:

Comments on Colorado River Management efforts from the U.S. Department of the Interior, Kameran Onley, Acting Assistant Secretary for Water and Science, DOI Assistant Secretary Onley will discuss the significant challenges presented by diverse social, cultural, and ecological demands within the Colorado River Basin. She will talk about the complex endangered species recovery efforts, invasive species management, natural and cultural resource stewardship, and the continued need for water and power development. After more than 100 years of DOI management of the River Basin, today’s Adaptive Management process helps find a balance for the restoration and conservation of the Colorado River Basin.

11:00 - 11:30 AM – Climate Change:

Effects of Interannual Variability and Climate Change on the Colorado River, Brad Udall, Director, Western Water Assessment, NOAA, Boulder, CO A major question hangs over the States that depend on the Colorado River: is the present drought one of those that are known to occur once or twice in a century in the American Southwest, or is this a new kind of drought, of a more chronic or permanent nature, that we have not seen before?

12:15 - 12:45 AM - Stream Flow Management for Restoration:

Streamflow Management for River Restoration: Lessons from Outside the Colorado River Basin for Moving from Sites to Systems, Christopher Conrad, The Nature Conservancy, Seattle, WA Using examples from a number of efforts from around the United States grappling with restoration issues that extend beyond a single site, Conrad will explore the value of coordinating activities at larger scales.

1:45 - 2:15 PM - Sustainability and River Restoration:

Sustainability and River Restoration in the Colorado River Basin, Kathy Jacobs, Arizona Water Institute, Tucson, AZ A consensus exists among managers that more extreme events, both floods and droughts, are likely to result from climate change. An ability to respond to these anticipated changes will be the hallmark of successful river restoration programs. Jacobs will address the opportunities for identifying and responding to changes more quickly.

3:00 - 3:30 PM - Status of Colorado River Native Fishes:

Current Status of Colorado River Native Fishes, Matthew Andersen, U.S. Geological Survey, Flagstaff, AZ The recovery of native fishes is one of the issues driving restoration efforts in the Colorado River Basin. Multiple agencies are tracking native fishes, particularly the four species federally listed as endangered: humpback chub, bonytail, Colorado pikeminnow, and razorback sucker. This presentation will provide the most current information available on the status of these species, including humpback chub improvements, in the Colorado River Basin.

WEDNESDAY, NOVEMBER 19

8:15 – 9:00 AM - Quagga Mussel Spread and Ecological Impacts:

An Overview of the Spread and Ecological Impacts of the Quagga Mussel with Possible Implications of its Recent Discovery in the Colorado River Basin, Thomas F. Nalepa, National Oceanic and Atmospheric Administration, Ann Arbor, MI The ecological impacts coincident with the expansion of the quagga mussel—an invasive species that favors deep lakes and reservoirs—in the Great Lakes have been profound, resulting in millions of dollars of damages. Lessons learned in the Great Lakes can help inform understanding of the possible impacts of the mussel on the Colorado River Basin; the mussel was detected in Lake Mead in 2007.

9:00 – 9:45 AM - Flows, Fish, and Conservation in the Green River:

Natural Flows, Invasive Fishes, and Native Fish Conservation in the Green River Downstream of Flaming Gorge Dam, 1962 to Present, Bestgen explores the effects of newly implemented flow changes and drought-induced warming on the fish community of the upper Green River. The effects of warming on fish populations, particularly the expansion of invasive species, in the Green River may provide insights for other Colorado River managers confronting drought-induced warming.Kevin R. Bestgen, Colorado State University, Fort Collins, CO

4:20 – 4:40 PM Quagga Mussel Monitoring in Lake Mead:

A Standardized Design for Long-Term Quagga Mussel Monitoring in Lake Mead, David Wong, University of Nevada, Las Vegas, NV On January 6, 2007, the quagga mussel was detected in Lake Mead. This invasive species not only clogs water pipelines, but also will have profound impacts on the Lake Mead natural system. Efforts to track the abundance and distribution of the quagga mussel in Lake Mead will be discussed.

THURSDAY, NOVEMBER 20

8:00 – 8:30 AM - Economic Values for Park Service Resources:

Increasing levels of nitrogen deposition associated with industry and agriculture can drive soils toward a toxic level of acidification, reducing plant growth and polluting surface waters, according to a new study published online in Nature Geoscience.

The study, conducted in the Tatra Mountains of Slovakia by the University of Colorado, University of Montana, Slovak Academy of Sciences, and the U.S. Geological Survey, shows what can happen when nitrogen deposition in any part of the world increases to certain levels—levels similar to those projected to occur in parts of Europe by 2050, according to some global change models.

On the basis of these results, the authors warn that the high levels of nitrogen deposited in Europe and North America over the past half century already may have left many soils susceptible to this new stage of acidification. The results of this further acidification, wrote the authors, are highly reduced soil fertility and leaching of acids and toxic metals into surface waters.

A long history of human-influenced nitrogen deposition has left soils in the Western Tatra Mountains of Slovakia highly acidic. The study reveals that the increased nitrogen load in the region triggers the release of soluble iron into alpine grassland soils. This iron release is indicative of extreme soil acidification, comparable to conditions seen in soils exposed to acid mine drainage.

“Recovery from such extreme chemical change could only occur in geologic time, which is why soil is considered a non-renewable resource,” said USGS scientist Jill Baron, who helped analyze and interpret the study results.

In addition to this research, Dr. Baron has investigated the impacts of nitrogen deposition in Rocky Mountain National Park for 26 years. “The Rocky Mountains and the Tatra Mountains represent the two ends of the atmospheric deposition effects trajectory,” Dr. Baron said. “The effects of nitrogen deposition in Rocky Mountain National Park are just beginning to be observed, allowing resource managers the opportunity to help the region recover if deposition is reduced. In the Tatra Mountains National Park, however, soils are far beyond natural recovery in human time frames.”

Much of the eastern U.S. and Northern Europe fall in the middle of the effects spectrum, she added.

Rocky Mountain and Tatra National Parks are sister parks, with scientists and managers beginning to cooperate in studies to understand both. Dr. Baron’s work in Rocky Mountain National Park led to the establishment of a nitrogen threshold for the park in 2006, the first time the nation has established a critical load of a pollutant for any park environment. An agreement in 2007 between the Environmental Protection Agency, National Park Service, and Colorado Department of Health and Environment enabled the agencies to set target loads for reducing nitrogen emissions by 2012 to improve ecological conditions.

Earthquakes are far more than just geological phenomena-they can greatly alter the way people live by damaging whole communities.

A new USGS video production, “The Great Southern California ShakeOut: An Earthquake Scenario Based On Science,” shows how science is used by government agencies, emergency responders, policymakers and the public to help build safer communities. It is based on the USGS ShakeOut Scenario, the scientific foundation for the Great Southern California ShakeOut, a region-wide earthquake drill conducted on November 13, 2008.

“When I gaze out my window, I realize that every building, every high-rise I can see from the 15^th floor here in city hall in Los Angeles, will be impacted by this catastrophic earthquake,” said Jim Featherstone, General Manager, City of Los Angeles Emergency Management Department, in an interview in the video, referring to the theoretical magnitude 7.8 earthquake that is part of the ShakeOut Scenario. “The science of the Great ShakeOut has allowed me to bring that perspective home.”

Other interview subjects include the USGS, the Office of Homeland Security, the County of Riverside, the California Governor’s Office, the East Valley Water District, the Art Center College of Design, the County of San Bernardino, and a professor emeritus from Colorado State University.

In addition to interviews, this video also discusses how such an earthquake would affect downtown Los Angeles and the San Andreas Fault-crossing Cajon Pass, a narrow corridor through the San Gabriel Mountains known as an important “lifeline corridor” where roads, railroads, water and energy pipelines, and electrical and communications infrastructure provide service to millions of residences, businesses, commuters and communities in Southern California.

You can view this video in episode 75 of CoreCast at www.usgs.gov/corecast. Learn more about the USGS’s role in the Great ShakeOut at www.usgs.gov/shakeout. More information about the Great Southern California ShakeOut can be found at www.shakeout.org.

The U. S. Geological Survey is joining with the National Oceanic and Atmospheric Administration (NOAA) and Environment Canada (EC) in jointly operating and calibrating high-tech climate monitoring stations. NOAA recently installed a U.S. Climate Reference Network sensor in Egbert, Ontario, while EC set up a Canadian Reference Climate Station at the USGS Earth Resources Observation and Science (EROS) Center near Sioux Falls, S.D.

“USGS is pleased to work with NOAA and Environment Canada in the effort to monitor key climate variables,” said Eric Clemons, director of USGS-EROS. “When compiled on a national and international scale, these data records are essential in understanding global environmental impacts. They have to be as accurate and as comprehensive as possible.”

Both stations collect detailed weather and climate data, including real-time measurements of surface temperature, precipitation, wind speed, and solar radiation. Scientists will compare each nation’s measurements and blend the two networks together to understand climate change and precipitation trends better. The ongoing collaboration will result in improved accuracy and common quality control procedures for the data - even a similar, common way to measure snowfall and snow depth.

NOAA’s National Climate Data Center first installed a climate reference station at USGS-EROS in 2002. Due to its centralized location in the U.S., the technical expertise of its staff, and the existence of a suitable infrastructure, USGS-EROS became a prime candidate for the installation of similar climate-monitoring instruments operated by EC as part of a U.S.-Canadian climate research effort.

Through agreements with multiple agencies, USGS-EROS provides support for eight in situ (stationary) networks for monitoring climate, weather, and natural and human-influenced hazards. USGS uses these data to support land science and climate change research.
