- Location:
-
HOPS is located at the Hopland
Research and Extension Center of the
University of California Agriculture and Natural Resources unit.
- Geology:
-
Franciscan Formation
- Vault/Borehole conditions:
-
The instruments are located in a steel and
concrete vault benched into a hillside with 2
meters of soil overburden. The vault is oriented
north/south to minimize the effects of solar
heating. The concrete pier is covered with 4" of
insulation on the sides and 8" of insulation on
the top. The datalogger and supporting
equipment are in an adjacent room.

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.
