Abstract
During the TASGO Project in 1995, offshore deep seismic reflection profiles were recorded by AGSO?s R/V Rig Seismic along a series of traverses around Tasmania totalling 1758 km in length. Thirty-three portable AGSO seismic recording systems and six University of Tasmania Observatory fixed stations operated continuously onshore during this survey recording seismic arrivals from the ship?s air-guns. They provided wide-angle and refraction data with a range of source-receiver distances and azimuths. The arrivals have travel paths which pass through the major tectonic elements of Tasmania, and penetrate to below the crust-mantle boundary. They form a substantial new data set for imaging the detailed two-dimensional structure (when combined with the reflection profiles), and the regional three-dimensional structure of the State using tomographic techniques.This record documents the procedures used for processing and displaying the data and the structure of the archived data. The initial processing procedures were different for the analogue data and the digital data. The final processing, signal enhancement and display are common to both types of data.
