ACTION ITEM: T360 vault sensors (Version 2): The SC endorses a plan for seven of the 14 T360-v1-vault sensors to be upgraded to v2. Some of these new sensors will be subjected to testing (against STS-1 performance and VBB specs) to evaluate their effectiveness as a VBB vault sensor. The SC looks forward to further data comparison results of the new T360-v2 vault sensor, both from the continued operation of the Black Forest Observatory (BFO) joint test, and at one or more other locations.
Update from B. Woodward - IRIS Instrumentation Services Activities
Update on testing of next generation (version 2) of T360 vault and borehole sensors (at BFO and ASL)
Discussion on how to upgrade remaining GSN stations with Vault Sensors; Estimates of associated budget costs
GSN Design Goals - update on formation of Working Group; Proposed presentations for the SIG at the SAGE/GAGE Workshop
GSN Metrics: New data gap analyses; Improved noise performance at GSN stations upgraded with borehole sensors
