[ANSS-netops] Vaults and ARRA upgrade stations

[Mark E Meremonte]

Nathan,

I cannot recall exactly what that *.ppt file showed but I think it showed 
various vaults tested at ASL including a smaller style vault for, what I 
called, "remote style".  In any case, since then John McMillan and I have 
designed a vault system with a glass base using an off-the-shelf salvage 
drum that has a lid with an o-ring and using a PVC bulkhead fitting for 
cable entry.  This vault is similar to one I showed at last NETOPS meeting 
where it was used as a table and/or chair.  See photos of our mockup at 
ftp://hazards.cr.usgs.gov/meremonte/Station-Vault/VaultDesign/Vault_SalvageDrum 
and see an installation for the station PLID (Pearl Lake, ID) at 
ftp://hazards.cr.usgs.gov/meremonte/Station-Vault/VaultDesign/Vault_SalvageDrum/Installed_PLID_Photos
.
 
As for response of the system see IRIS PDF plots for PLID at 
http://www.iris.washington.edu/servlet/quackquery/pdfDrill.do?station=PLID&yyyyDDD=2010.032&length=31&location=++&channel=BHZ&network=IW
.   This vault is installed in the Idaho Batholith using a CMG3-ESP and a 
MEMS.

Also, we installed the same vault and seismometers at stations FXWY and 
REDW in IW network.  FXWY is in an old limestone quarry and REDW is on a 
couple meters of fine-grained clay soil mixed with boulders on a limestone 
ridge.  The PDF plots plotted for same period of time as for PLID above 
are at:

We were wondering what other networks are doing in regards to the 
construction of new vaults, broadband in particular.  Maybe something 
along the lines of one that Mark Meremonte covered in this presentation?
