While archaeology is often considered to focus on the land that lies beneath our feet, significant amounts of material culture have been lost to us beneath water, whether in seas, lakes, rivers, or submerged caves. The world of underwater archaeology, however, is increasingly recognized as a field that is vital to our understanding of the past. The chapters gathered together into this volume draw on research first presented at the Fourth Warsaw Seminar on Underwater Archaeology, held at the University of Warsaw on 18-20 November 2021. From the seas of the Caribbean through to the Mediterranean and Norway, and from Antiquity through to contemporary times, the chapters presented here offer a dazzling array of different approaches to underwater archaeology and outline the potential that changing technology presents in this expanding field. |
