Deploying Team Members: William C Burk . Kevin L Filiatrault . Ralph C Himmelsbach . Jimmy L Jackson . Aaron J Jones . Douglas K Mac Donald . Alan M Yerington
Research Objectives: The Dry Valleys Seismic Project monitors regional and global seismicity. This station is an element in the Air Force Technical Applications Center (AFTAC) Southern Network (ASN). The network provides near real time data from nine locations within the southern hemisphere. The data is telemetered to the National Data Center in Florida and is available to the international scientific community.

Field Season Overview:
The project team members will perform corrective maintenance and repairs on the seismic stations at the Vanda borehole site and on Mount Newall. Researchers will travel by helicopter from McMurdo Station to the Dry Valleys where they will establish field camps at Lake Vanda and Mt. Newall. A helicopter will bring fuel to the remote sites by slingload and team members will transfer it to the seismic stations using an electric pump. The team plans to replace the wind generator mast at Mount Newall, and service the diesel generator systems.

The team members will return to McMurdo Station where they will work with the support contractor's staff to re-route the data signal to the CTBT hub room in building 159.

The team leader will train the winter-over science technician in the operation of the seismic and remote power systems. Data from the stations will be collected year round and transmitted to the International Data Centre in Vienna.
