Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: August 1977 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: August 1977
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

Catalog of seismic records obtained in support of the ERDA/Nevada Operations Office, October 1963 through June 1976 Catalog of seismic records obtained in support of the ERDA/Nevada Operations Office, October 1963 through June 1976
The United States Geological Survey (USGS), Branch of Earthquake Hazards (BEH), Las Vegas, Nevada has provided ERDA, Nevada Operations Office, with seismic monitoring support to the underground nuclear weapons test program conducted at the Nevada Test Site (NTS) since September 1961. Activities from September 15, 1961 to September 13, 1963 are summarized in the report, "Seismic Dats...

Recent and relict topography of Boo Bee patch reef, Belize Recent and relict topography of Boo Bee patch reef, Belize
Five core borings were taken on and around Boo Bee Patch Reef to better understand the origin of such shelf lagoon reefs. The cores reveal 4 stages of development: (1) subaerial exposure of a Pleistocene "high" having about 8 meters of relief, possibly a Pleistocene patch reef; (2) deposition of peat and impermeable terrigenous clay 3 meters thick around the high; (3) initiation of...

Frequency response of the USGS short period telemetered seismic system and its suitability for network studies of local earthquakes Frequency response of the USGS short period telemetered seismic system and its suitability for network studies of local earthquakes
The USGS telemetered seismic system was intended primarily to record small to moderate earthquakes (magnitude 0 to 4) at distances of a few km to several hundred km. Its frequency response is such that the recorded background noise at a moderately quite Coast Range site has a relatively flat 'record' spectrum from about 1/3 Hz to about 20 Hz. With the system magnification set so that the
