This volume contains updated, reviewed versions of some selected papers on "Sea-Level Changes and Their Effects" presented at the International Ocean and Atmosphere Pacific Conference (OAP 95), held in Adelaide, South Australia, 23-27 October 1995. In addition several reviewed articles on important topics not covered by the papers presented at OAP 95 were invited. The articles in this volume should find an audience among coastal developers, marine biologists and environmentalists. They cover a range of topics including the efforts of long-term sea-level rise on coastal flows and its impact on mangrove communities, the determination of long-term sea-level changes due to tides, tsunamis and the weather.
