Facility Plan for Polar Seismic and Geodetic Science is Available

The seismic and geodetic Polar communities have worked with IRIS and UNAVCO to provide a plan for the growth, development, management and governance of Polar support services for the NSF facilities. This plan is now complete and posted on the IRIS webpage.

Here is the executive summary from the report:

Installing a "Cold and Dark" Seismic Station in the Yukon

On October 8-13, 2012, a three-man team from the EarthScope Transportable Array and IRIS/PASSCAL installed a prototype "cold and dark" seismic station at Eagle Plains, Yukon Territory, Canada, just 30km south of the Arctic Circle.  The station installation developed new methodologies for drilling a shallow, 55" deep borehole in exposed bedrock. Protection for electronics, power, and communication subsystems (from the elements, and from large wildlife) was provided by an all-weather hut bolted to bedrock.

AGU 2012 PASSCAL Data Archiving Workshop

December 2, 2012
San Francisco-Palomar Hotel

An IRIS PASSCAL data-archiving workshop will be offered prior to the 2012 Fall AGU meeting in San Francisco. This workshop will serve as an opportunity to help PIs and archivers familiarize themselves with the data group, the support provided by the data group, and the software utilized in the archival process.

PASSCAL Intern Spends Summer on the Ice

IRIS/PASSCAL summer intern Alan Shi has some interesting stories to tell about his last few months with the PASSCAL Instrument Center in Socorro, NM.  The season began calmly enough, and Alan enjoyed developing a testing enclosure to verify that field equipment boxes such as the MEVO (Mt. Erebus Volcanic Observatory) boxes were distributing power properly, as well as performing ruggedness-testing of memory sticks before their use to collect data in arctic regions. But, the most impressive part of Alan's summer by far was his deployment to the rapidly-changing ice sheets of Greenland.  Here are some recollections and photographs of intern Shi's experiences on the ice.

Mendenhall Glacier, Up Close and Personal

IRIS/PASSCAL has been a key supporter of a novel deployment of equipment at Mendenhall Glacier in Alaska.  A team of researchers from the University of Alaska Southeast, the University of California Santa Cruz, and the Alaska Science Center in Anchorage have been performing an ambitious analysis as part of a low-budget cutting-edge project. Above, a Trillium Compact AT is lowered directly into a borehole in the glacier.
