Abstract

Over many years the Australian Geological Survey Organisation (AGSO), and its predecessor the Bureau of Mineral Resources, Geology and Geophysics (BMR), has acquired wide-angle seismic profiling data to determine velocity structures of geological features within various minerals and petroleum provinces. Wide-angle seismic profiling is a technique used where the shot-to-receiver offset is significantly greater than the target depth, e.g. for target horizons at 10 km the shot-to- receiver offset may be in the range 0-100 km. Basic information on the various surveys is commonly contained in operational reports written on each survey and published as GA (or BMR) Records. With the rapid increases in the amount of data acquired in recent years as data acquisition methods have improved and the resolution of geological structure has become more demanding, it hasbecome impractical to publish all the data from surveys in hard-copy form. Basic information such as recording station locations, shot data, shot times, instruments used, etc., is now stored in computer data files on various media. Hence there is a need to develop a database system to keep track of all the basic survey information. This Record descibes an AGSO wide-angle seismic profiling database that has been established using Microsoft Access® software which should enable users to locate and access basic survey information and data. It has been set up in such a way that it can be modified and improved with the addition of future data and new "fields" of information as required. The current database includes more recent surveys in the Browse Basin and Otway Basin. Survey data are accessed using a unique identifier for each survey (based on the date of firing the first shot). The scope of data being accessed will improve with the addition of older survey data. It is intended that database information and the computer data files be archived at regular intervals on a CD-ROM format
