Network Contact:
Lamont-Doherty Earth Observatory of Columbia University 61 Route 9W Palisades, NY 10964 |
| Coordinates:
Latitude: 44.6197N Longitude: 74.5829W | Elevation to Sensor: 440 m
Depth to Sensor: 0 |
| Geology: Potsdam Sandstone, Cambrian Period | |
| Vault Conditions: Sensor sits directly on sandstone outcrop covered by wooden box | |
| Site Description: Wooded area with little traffic | |
| Station Instrumentation: Remote site:
Guralp DM/24 external GPS clock spread-spectrum digital radio transmitter solar panel with gelcell battery | |
| Data collection site:
spread-spectrum digital radio receiver PC windows2000, SCREAM! (Guralp Dataserver), Earthworm | |
| Operated Since: November 19, 1999 | |
| Comments:
Spread-spectrum digital radio transmitter had problems in communicating with the receiver at the roof top of Raymond Hall at SUNY Potsdam campus. Hence, it did not work during spring through fall when leaves on tree branches are blocking the path. In the summer of 2003, we installed 32 feet antenna tower at the station and worked well for few weeks. Then, the station is dead due to too much snow covering solar panels(?). | |
| Comments on the New Seismic Vault Location:
The new seismic vault for STS-2 broadband seismometer for the ANSS backbone station at Lake Ozonia is conscructed about 40 feet (12 meters) from the old vault (see photo #3). The old vault shown on photos #1 and #2 housed CMG-3ESP broadband seismometer for the LCSN station LOZ. Coordinates from the data loggers equipped with GPS receivers of the two vaults are nearly identical, because two data loggers used the same steel pole shown in photos #2 and #3 due to GPS reception problem. However, as shown on photos #2 and #3, siesmometers at two vaults must be separated by at least 12 meters (40 feet). Hence, it may be allowed to assign a new station code name for the new ANSS backbone station as LONY (Lake Ozonia). | |
