Dramatic Developments at Kilauea Volcano
Explosive eruptions and noxious gas emissions at Kilauea Volcano in Hawaii have prompted scientists to work around the clock to understand what will happen next and how to keep the public out of harm’s way. Scientists are monitoring gas emissions and seismic activity at Kilauea, which on March 19 experienced its first explosive eruption since 1924. The volcano is also emitting sulfur dioxide at toxic levels. The USGS is issuing frequent updates, which can be accessed at http://hvo.wr.usgs.gov/kilauea/. To listen to a podcast interview with USGS Volcano Hazards Program Coordinator John Eichelberger describing the activity at Kilauea, visit http://www.usgs.gov/corecast/.

Groovin to the Tunes of Nature
Just what does a bear do in the woods? USGS scientist Kate Kendall knows. Kendall’s group recently used remote photography to learn more about black bear’s and grizzly bear’s use of naturally occurring bear rubs and how they respond to baited hair traps. The video and photographs are part of a study to determine the size and distribution of bear populations in northwestern Montana. Bears are identified and counted through genetic analysis of hair samples collected from barbed wire hair traps and bear rub trees. To find out more about the project and view the footage, visit http://nrmsc.usgs.gov/news/KendallRemoteCamera.htm or contact Katherine Kendall at (406) 888-7994 or kkendall@xxxxxxxx
April Showers May Bring Spring Flooding
A series of winter storms has left parts of the Midwest and New England buried under snow, and many USGS Water Science Centers are anticipating significant spring flooding. The USGS operates a network of more than 7000 streamgages that measure the flow and height of streams and rivers throughout the United States. The gages relay measurements 24 hours a day, seven days a week, through telephones or satellites to offices where data is processed automatically. Users, such as the National Weather Service, rely on USGS gage data for flood forecasting and to notify emergency managers. Field personnel are routinely dispatched to collect and verify data during storms or floods. For more information on USGS flood-related activities, visit http://water.usgs.gov/osw/, or for more detailed information by state, visit http://water.usgs.gov/district_chief.html. You can also contact Diane Noserale at (703) 648-4333 or dnoseral@xxxxxxxx.

United States and Indonesia to Establish Regional Volcano Observatory in North Sulawesi
The United States recently signed an agreement with Indonesia to create a regional volcano observatory in the North Sulawesi-Sangihe Islands. The agreement calls for scientific agencies from both countries to establish a regional volcano observatory with the capability to monitor volcanic activity and provide early warning of volcanic eruptions. The North Sulawesi-Sangihe Islands area is home to 11 active volcanoes and has a vulnerable population of close to a half million people. Based in Vancouver, Wash., the U.S. Volcano Disaster Assistance Program combines the scientific expertise of the USGS with the disaster relief experience of the U.S. Agency for International Development’s Office of U.S. Foreign Disaster Assistance. For more information, visit http://jakarta.usembassy.gov/, or contact Clarice Ransom at (703) 648-4299 or cransom@xxxxxxxx.
National Earthquake Conference — Understanding Earthquakes: From Research to Resilience
The USGS is co-sponsoring the 2008 National Earthquake Conference held April 22–26, 2008, in Seattle, Wash. Conference activities include a plenary session featuring USGS Director Mark Myers, live webcast sessions with colleagues in countries impacted by the 2004 Sumatran earthquake and tsunami, working group panels and discussions, posters, field trips, and more. The latest research, successful hazard mitigation, and response programs in the public and private sectors will be showcased. Strategies and new approaches to achieving resiliency to earthquakes will be debated and discussed. For more information and to register, visit http://www.earthquakeconference.org, or contact Joan Gomberg at (206) 616-5581 or gomberg@xxxxxxxx.
Alaska Volcano Observatory Turns 20
This April, the Alaska Volcano Observatory (AVO) is celebrating 20 years of partnership in support of public safety and volcano science. Alaska has dozens of active volcanoes, some of which erupt explosively multiple times a year. Since the 1989–1990 eruption of Redoubt Volcano in Alaska and a near-disastrous encounter between a resulting volcanic ash cloud and a jet aircraft, the AVO’s use of advanced technology to monitor volcanoes and issue timely warnings has helped to insure that no additional damaging encounters with volcanic ash have occurred in Alaska. AVO’s success would not have been possible without strong partnerships with other government agencies and the private sector. The AVO has also contributed to a better understanding of how volcanoes work and what role volcanoes play in shaping Alaska’s dynamic landscape. The AVO is a collaborative project of the USGS, the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of Geological and Geophysical Surveys. To commemorate the AVO’s 20th anniversary, events will be held on April 2 in Washington, D.C., and on April 29 in Anchorage, Alaska. For more information, visit the AVO Web site at http://www.avo.alaska.edu, or contact Jennifer Adleman at (907) 786-7019 or jadleman@xxxxxxxx.

USGS Expertise Improves Life for Millions of Iraqis
Scientists and engineers from the USGS and other agencies are working with employees of Iraq’s Ministry of Water Resources to construct a modern hydrometeorological network for providing real-time information vital for public water supply, agricultural needs, ecological restoration, and flood control. The USGS, with more than 100 years of stream-gaging expertise, taught them how to use real-time, satellite-assisted stream-gauging stations and how to take field streamflow measurements with acoustic Doppler current profilers. This training enabled them to better analyze and manage Iraq's valuable water resources. Funding and equipment were provided by the U.S. Department of State’s Iraq Transition Assistance Office and the Italian Ministry of Environment and Territory. For more information, visit http://www.peoplelandandwater.gov/scienceandstewardship/usgs_03-14-08_usgs-expertise-improves.cfm, or contact Timothy Merrick at (208) 387-1305 or tmerrick@xxxxxxxx.
$3.4 Million in Earthquake Research Grants
The USGS will award up to $3.4 million in grants and cooperative agreements for earthquake research in 2009. Interested researchers can apply online at www.grants.gov. Applications are due May 15, 2008. USGS grants support research that will assist in achieving the National Earthquake Hazards Reduction Program’s goal to mitigate the nation’s earthquake losses by providing earth science data and assessments essential for land-use planning, engineering design, and emergency preparedness decisions. Last year, the USGS awarded 92 research grants to universities, state geological surveys and private institutions.

Invasions Lead Extinctions by 24-to-1
Plant invaders keep on coming, with no end in sight. This is bad news for native species. Plant species from other countries continue to invade the United States at alarming rates, according to a recent paper in Ecology Letters authored by USGS scientist Tom Stohlgren and colleagues. Over the past 400 years in the United States, exotic species invasion rate exceeds their extinction rate by roughly a 24-to-1 margin. On average, four or five plant species per year have invaded the Pacific Northwest states over the past 100 years. Authors of this new paper also report that the plant invasions are continuing, exotic plants are rapidly spreading county to county, and the greatest invasions occur in plant communities with the largest number of native species. Currently there is no sign that native plant communities are filled to the brim with native species. Many of these exotic plants are noxious weeds, which increase fire hazards and degrade property values and wildlife habitat.

STORY SEEDS: (points to ponder or investigate)
Baseball Season is Here! Time to Play in the Clay
Clay is used on baseball and softball fields in the base paths, batter’s boxes, bullpens, pitcher’s mounds, and practice areas. If used by itself, however, clay is not an ideal surface for play. In the early days of baseball, the clay infield would become as hard as concrete in the summer heat and a slippery marsh after a rain storm. One improvement in the evolution of field clay is calcined clay, which is clay that has been heated in a furnace at about 2,000º F. Once calcined, the clay is ground into a powder that readily absorbs water, reduces soil compaction, and will not stick to cleats. This type of product is used as an infield conditioner and to dry wet spots on a field or track quickly. For more information about clays, visit http://minerals.usgs.gov/minerals or http://minerals.usgs.gov/minerals/pubs/general_interest/sport_mins/clay_surfaces.pdf, or contact Robert Virta at (703) 648-7726 or rvirta@xxxxxxxx.
Could Doppler Images Capture More than the Weather?
When we watch the weather forecast on television, we often see images depicting current conditions produced by Doppler radar. This same system also inadvertently records migrating birds. USGS scientist Rick Sojda has been working with a Montana State University graduate student to develop artificial intelligence based algorithms to determine if birds can be digitally detected. Next fall, the group will record large flocks of geese in the Midwest, download the corresponding weather radar scenes, and further test the theory. For more information, contact Rick Sojda at (406) 994-1820 or sojda@xxxxxxxx.
