Design concepts for a Global Telemetered Seismograph Network Design concepts for a Global Telemetered Seismograph Network
This study represents a first step in developing an integrated, real-time global seismic data acquisition system a Global Telemetered Seismograph Network (GTSN). The principal objective of the GTSN will be to acquire reliable, high-quality, real-time seismic data for rapid location and analysis of seismic events. A secondary, but important, objective of the GTSN is to augment the...

Landslide overview map of the conterminous United States Landslide overview map of the conterminous United States
The accompanying landslide overview map of the conterminous United States is one of a series of National Environmental Overview Maps that summarize geologic, hydrogeologic, and topographic data essential to the assessment of national environmental problems. The map delineates areas where large numbers of landslides exist and areas which are susceptible to landsliding. It was prepared by...

A Proposed Model for the International Geomagnetic Reference Field-1965 A Proposed Model for the International Geomagnetic Reference Field-1965
A best current model of the main geomagnetic field is presented as a response to a need for an “International Geomagnetic Reference Field”. This model is described by a series of 120 spherical harmonic coefficients and their first and second time derivatives from an epoch 1960.0. It was derived from a sample of all magnetic survey data available from the interval 1900-1964 plus a recent...

Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: November 1982 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: November 1982
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.

Rectangular harmonic analysis applied to the geomagnetic field Rectangular harmonic analysis applied to the geomagnetic field
Spherical harmonic analysis of the earth's magnetic field is limited in the resolution that can be obtained. This limitation is caused by inadequacies of computers and of available data sets. The fundamental wavelength in spherical harmonic analysis is the circumference of the earth. To resolve wavelengths as short as 100 km would require a spherical harmonic analysis carried out to a...
