[OBSIPtec] Cascadia Initiative: Relative orientation error, temporary data restriction

[Brent Evers]

The OBSIP Management Office (OMO) has restricted access to the Cascadia Initiative dataset (network ID 7D) at the IRIS Data Management Center (DMC) in order to resolve a channel naming error that results in a large number of stations having an incorrect relative orientation.  The channel-naming errors affected LDEO OBS data in Year 1 and Year 2 and the SIO OBS data for Year 2.  As a result of this change, OBSIP will make all of the Cascadia Initiative data consistent in relative orientation.
 
Specific details of the issue will be made available shortly on the OBSIP website Cascadia experiment page:
 
http://www.obsip.org/experiments/experiment-list/2011/cascadia
 
The OMO is working with OBSIP instrument centers to resolve the issue as expeditiously as possible.  When the corrected data are again available for open distribution from the DMC, the OMO will notify the community. 
 
For researchers still wishing to use the Cascadia data with known channel naming issues, or for any other questions relating to this issue, please contact Jessica Lodewyk (jessica.lodewyk at iris.edu) at the OBSIP Management Office to receive access.
