# 86: Geophysics

## Introduction

Geophysics: Applications typically involve material in Mechanics and Fluid Mechanics, but for large-scale problems (this subject deals with a very big solid and a large pool of fluid!) With the advent of Global Positioning Systems there has been a good deal of interest in geodesy and triangulation, which is included here.

## Applications and related fields

Simple spherical geometry (and trigonometry) is treated in 52A55: Spherical Geometry.

## Subfields

There is only one division (86A) but it is subdivided:

• 86A04: General
• 86A05: Hydrology, hydrography, oceanography, See also 76B15, 76B20, 76B25, 76C15, 76E20, 76Q05, 76Rxx, 76U05
• 86A10: Meteorology and atmospheric physics, See also 76Bxx, 76C15, 76C20, 76E20, 76N15, 76Q05, 76Rxx, 76U05, 76V05
• 86A17: Global dynamics, earthquake problems
• 86A30: Geodesy, mapping problems
• 86A32: Geostatistics

## Textbooks, reference works, and tutorials

There is a sci.geo.* hierarchy of newsgroups (e.g. sci.geo.satellite-nav) which may be relevant in general. For geodesy there is an additional newsgroup comp.infosystems.gis.

## Software and tables

Dynamic Stress/Deformation Analysis Software

Geology software.

Relevant packages from the Computer Physics Communications package library.

A number of elementary posts hoping to reconcile distances and angles (bearings) with positions on a spherical earth; repetition justified here in the attempt to satisfy the many questioners...
