The 31st annual Alaska Run for Women is scheduled for Saturday morning at the University of Alaska Anchorage Cuddy Quad.

The event traditionally draws thousands of women with the goal of raising awareness and funds to end breast cancer and promote mammograms and early detection.

Due to an expected large crowd, preregistration is strongly recommended at www.akrfw.org. Other information, including the course and parking availability, and the virtual run option are also available on the site. The run has no registration fee, but a $25 donation is suggested and greater donations are welcomed.

This was day number two of an international research team’s weeklong field campaign to quantify and later analyze carbon dioxide emissions to gain more insight into the activity of the island’s Mt. Edgecumbe volcano. The volcano reawakened last year, presenting low-level earthquakes and some ground deformation after an approximately 800-year dormancy.

The team includes researchers from the University of Alaska Fairbanks Geophysical Institute, the University of Perugia in Italy and the University of Alicante in Spain. Two of the Geophysical Institute participants are Ph.D. student researcherswho did their coursework through the UAF College of Natural Science and Mathematics.

Geophysical Institute Research Assistant Professor Társilo Girona is the principal investigator on the research, which is funded by a NASA program for early career scientists.

The work centers on testing one of Girona’s hypotheses: that a correlation exists between the emergence of low-temperature geothermal anomalies on active volcanoes and the release of carbon dioxide through the ground.

Understanding the restless fault's mantle-to-crust connections provides critical information for understanding the lithospheric-scale fault's seismic cycle, says Newell, associate professor in USU's Department of Geosciences.

He and colleagues Jeff Benowitz, an Alaska-based geochronologist, Sean Regan of the University of Alaska Fairbanks, and doctoral candidate Coleman Hiett of USU, collected and analyzed helium and carbon isotopic data from springs along a nearly 250-mile segment of the fault and published their findings, "Roadblocks and Speed Limits: Mantle-to-Surface Volatile Flux in the Lithospheric Scale Denali Fault, Alaska," in Geology.

"Active strike-slip faults like Denali have three-dimensional geometries with possible deep conduit connections below the Earth's surface," Newell says. "But we don't know much about how and if these connections are maintained."

To examine these possible deep connections, Newell and Regan sampled 12 springs along the Denali and Totschunda Faults, by way of helicopter and on foot, to the remote, mountainous regions of Alaska's interior.
