USGS Scientists Present at the 2012 Geological Society of America meeting
The annual Geological Society of America meeting will be held in Charlotte, North Carolina November 4-7. USGS Alaska Science Center Research Geologist, Dwight Bradley, will present an invited Pardee talk as part of a special symposium Supercontinent Cycles through Earth History. The talk entitled “Lithium-cesium-tantalum pegmatites through time, their orogenic context, and relationships to the supercontinent cycle” will present a refined global age distribution of LCT pegmatites that is similar to those of orogenic granites and detrital zircons. In addition, researcher Rob Witter (ASC) will present “Little strain accumulation and release on the Alaska-Aleutian megathrust beneath the Shumagin Islands in the last 3400 years?” discussing Russian accounts of a strong earthquake followed by a tsunami in 1788, which implies rupture of the Alaska-Aleutian megathrust beneath the Shumagin Islands, Alaska.

II. Press Inquiries/Media
Mondadori Magazines France is preparing an issue entitled '100 Mysteries of Science,' which will feature an article on beak deformities among wild birds in Alaska, whose investigation is being led by USGS Alaska Science Center research wildlife biologist Colleen Handel. The article is scheduled to be published in the next issue (November) of Science et Vie Junior, a French scientific magazine for teenagers. The article will include photographs of birds from both North America and Europe that have been affected by avian keratin disorder, which can cause severe overgrowth and crossing of the beak but whose cause yet remains a mystery. This disorder is occurring in epizootic proportions in Alaska and the Pacific Northwest primarily among songbirds, and reports of birds with similar beak deformities have been documented recently in the United Kingdom and Europe.
Gillies wrote an article about the methods and highlighted an article entitled “A Simple Method for In Situ Monitoring of Water Temperature in Substrates Used by Spawning Salmonids” prepared by Zimmerman and James Finn that will be published in the Journal of Fish and Wildlife Management.
