- Location:
-
The site is located in the
Jasper Ridge
Biological Preserve in Stanford, California. It is the
replacement installation for the STAN
location and is operated cooperatively
with Stanford University.
- Geology:
-
Serpentine
- Vault/Borehole conditions:
-
The vault is located in an east/west adit, 20' in
length, constructed for the development of Searsville
Dam (circa 1900). The instruments are located in
an aluminum pressure tank on a concrete pier.
Apporoximately 4 meters of overburden cover the adit.
The datalogger and accessory equipment are
located in front of the adit.

Several tools provide access to SEED format data at the NCEDC, both in terms of querying the archives and allowing data requests.- Querying the archives
- Requesting data by channel and time
- Requesting data by event
Help on using these tools is available.
