[OBSIPtec] Cascadia [7D] 2014-2015 LDEO APG Data Now Available at IRIS DMC

[Kasey Aderhold]

The Cascadia Initiative community seismic experiment marine deployment 
occurred offshore Washington and Oregon, with ocean bottom seismometers 
deployed and recovered from 2011 to 2015. Instruments that were deployed 
came from the Lamont-Doherty Earth Observatory, the Scripps Institution 
of Oceanography, and the Woods Hole Oceanographic Institution. Land 
stations were also deployed during this experiment and data from both 
off-shore and on-shore stations are archived and available under 
the_CASCADIA <http://ds.iris.edu/gmap/_CASCADIA>virtual network code at 
the IRIS DMC.

Data from the LDEO, WHOI, and SIO ocean-bottom instruments deployed in 
2014 and recovered in August-October 2015 are archived and publicly 
available under station code7D 
<http://ds.iris.edu/gmap/7D?timewindow=2011-2017>at the IRIS DMC. This 
data can be accessed using all IRIS DMC request tools. If you have any 
problems accessing this data or have questions, please contact Kasey 
Aderhold from the OBSIP OMO office at kasey at iris.edu. Data includes 
(*bold *indicates newly added):

  * 27 LDEO broadband stations (unfiltered high-rate Navy redacted
    data*, *high-rate data filtered at 3 Hz, *APG and temperature channels*)
  * 8 SIO ABALONE and 3 SIO LP4x4 broadband stations (unfiltered
    high-rate Navy redacted data, high-rate data filtered at 3 Hz, and
    DPG channels)
  * 24 WHOI broadband stations (unfiltered high-rate Navy redacted data,
    high-rate data filtered at 3 Hz, raw 1 Hz, and DPG channels)
  * 10 WHOI episensors (unfiltered high-rate Navy redacted data,
    high-rate data filtered at 3 Hz and raw 1 Hz)

LDEO APG redacted channels (HDH) are expected but are not currently 
available for the following stations: FS15D, G18D, G25D, G26D, G27D, and 
G34D.

Please note that theCascadia Initiative Channel Naming Conventions 
<http://www.obsip.org/experiments/experiment-list/2011/cascadia/cascadia-channel-naming-conventions>have 
been updated to reflect the different sampling rates of the two SIO 
instrument types.

More information about the Cascadia Initiative is availablehere 
<http://www.obsip.org/experiments/experiment-list/2011/cascadia> and in 
the DMC report folder <http://ds.iris.edu/data/reports/7D_2011_2017/>. A 
Cascadia Horizontal Orientation Report for the Year 4 deployment will be 
generated and published to this website in May, now that the redacted 
seismic channels have been archived.
