New Technique for Detecting Walruses with Thermal Imagery
The USGS Alaska Science Center and U.S. Fish and Wildlife Service collaborated on development of a new technique for detecting and enumerating groups of walruses in infrared imagery obtained with aerial surveys over sea ice. The new technique improves precision and allows effective use of infrared survey technology in much colder temperatures then was previously possible. This technique is being used to help estimate the size of the Pacific walrus population with data from a joint U.S.- Russian survey conducted in 2006. Details of the procedure will be reported in a soon-to-be-published article in the International Journal of Applied Earth Observation and Geoinformation and are currently available online at http://dx.doi.org/10.1016/j.jag.2009.05.004.

New Geologic Map Available of Cook Inlet, Alaska
A new digital geologic map of the Cook Inlet Region, Alaska has been released. The map includes substantive updates of previous regional maps and includes parts of the Talkeetna, Talkeetna Mountains, Tyonek, Anchorage, Lake Clark, Kenai, Seward, Iliamna, Seldovia, Mount Katmai, and Afognak 1:250,000-scale quadrangles. This map will assist in energy resource assessments of Cook Inlet, and will be used as part of the geologic map data sets of Katmai and Lake Clark National Parks that are currently being generated. This map can be found online at: http://pubs.usgs.gov/of/2009/1108/ .

USGS Scientists Track International Migrations of Yellow-billed Loons
Scientists with the USGS Alaska Science Center are traveling in late July to Cambridge Bay, Victoria Island in the Canadian territory of Nunavut to mark yellow-billed loons with satellite transmitters and collect blood samples for contaminants analysis. This species is sparsely distributed in the circumpolar Arctic and it is presently unknown whether breeding populations in the United States (Alaska), Canada, and Russia overlap during migration or winter. Understanding these international connections among populations is critical for assessing impacts of human harvest, sources of contaminants exposure, and potential for genetic differentiation. Conservation concern has recently heightened regarding harvest during migration in Alaska coastal waters and contaminants exposure while wintering in east Asia. Data from this marking trip will continue to build on similar marking efforts that have occurred in multiple populations in Alaska.

USGS Coordinating with State on Hazard Response in Alaska
Christina Neal, USGS Alaska Science Center geologist with the Alaska Volcano Observatory, will participate in the Alaska State Hazard Mitigation Advisory Committee conference call on July 23, 2009. These calls happen several times per year and involve representatives from state, federal, and local agencies dealing with hazards and emergency response in Alaska. The purpose of this call is to review the 2008 Tanana Basin flood disaster, the 2009 spring floods in Alaska, hazard mitigation activities and grant program for 2010, and the update of the State of Alaska Hazard Mitigation Plan.
