Arctic

On October 8-13, 2012, a three-man team from the EarthScope Transportable Array and EarthScope/EPIC 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.

The Polar Earth Observing Network (POLENET) is a large international, multidisciplinary project which is a core activity of the International Polar Year (IPY) 2007-2009.  The project combines Seismic and GPS instrumentation at remote sites in Antarctica.  The data collected during the POLENET experiment will enable new studies of the inner earth, tectonic plates, climate, and weather.  U.S. POLENET projects are supported by the National Science Foundation. EPIC supports the U.S. seismic portion of POLENET by providing specialized cold-hardened, equipment, field support, and training for University based field teams.

PASSCAL currently supports approximately 60 experiments per year worldwide, with 5-10% currently funded by the National Science Foundation (NSF) Office of Polar Programs (OPP). Polar projects commonly require a level of support that is several times that of seismic experiments in less demanding environments inclusive of very remote deployments (e.g. Tibet). In order to ensure OPP funded Antarctic projects the highest level of success, we have established a PASSCAL Polar Program and have secured funds from OPP to support new and ongoing experiments in Antarctica.

The primary focus of PASSCAL’s Polar support efforts are:
