AB: Concordia, Antarctica, Seismic Experiment for the International Polar Year (CASE-IPY for short) is part of a larger IPY initiative, the Polar Earth Observing Network (POLENET), which includes contributions from numerous countries including France, Italy, the United States and China. POLENET will focus on deployment of autonomous observatories at remote sites on the continents and offshore, coordinated with measurements made at permanent station observatories. With CASE-IPY, we plan to deploy 8-10 broad-band seismometers in East Antarctica, from the French/Italian station Concordia at Dome C, to the Russian station Vostok, with a possible extension towards the Chinese station at Dome A in collaboration with our Italian colleagues. We plan to deploy this profile during the 2008/2009 Antarctic summer season. In order to prepare for this deployment, we shall be installing three autonomous seismic stations close to the Concordia base this coming Antarctic summer (Dec 2007 - Jan 2008). Concordia is the site of an experimental permanent seismic observatory station, which has been operational since 2005. The extreme temperatures present at the site (-60°C) imply difficult operating conditions for the seismological equipment. The quality of data we obtain from this station has been steadily improving as we resolve the technical issues related to working at such low temperatures. The lessons we have learned from operating the Concordia station are being applied to the design of our CASE-IPY autonomous stations. We shall present details of the CASE-IPY project and results from the past two years of seismic observation at Concordia.
