Introduction to the 1996 special volume on DHEM

Abstract

This special volume of Exploration Geophysics has its genesis in a DHEM workshop held at Macquarie University in June, 1993. To attend this meeting, one had to be an author, or co-author, of a paper; ie, no observers, just participants. The presentations were to be progress reports, with a formal paper to be submitted for publication following the workshop. Abstracts for most of the papers were distributed in a folder given out at the workshop. Appendix 1 gives a list of the papers presented, the principal author and his then affiliation. This volume contains 13 papers which, mostly, are developments from the workshop presentations. The delay in publication can largely be laid at our feet-apologies to those (few) authors who submitted their papers promptly after the workshop.
