Geology and Archaeology: Submerged Landscapes of the Continental Shelf
Sea-level change has influenced human population globally since prehistoric times. Even in early phases of cultural development human populations were faced with marine regression and transgression as a result of changing climate and corresponding glacio-isostatic adjustment. Global marine regression during the last glaciation changed the palaeogeography of the continental shelf, converting former marine environments to attractive terrestrial habitats for prehistoric humans. These areas of the shelf were used as hunting and gathering areas, as migration routes between continents, and most probably witnessed the earliest developments in seafaring and marine exploitation, until the postglacial transgression re-submerged these palaeo-landscapes. Based on modern marine research technologies and the integration of large databases, proxy data are increasingly available for the reconstruction of Quaternary submerged landscapes. Also, prehistoric archaeological remains from the recent sea bottom are shedding new light on human prehistoric development driven by rapidly changing climate and environment. This publication contributes to the exchange of ideas and new results in this young and challenging field of underwater palaeoenvironmental investigation.

Abstract
This paper focuses on the continental shelf of NW Australia, and on models for change in littoral and offshore environments of relevance to human occupation over the last 50 kyr. Major island groups occur on the shelf including the Montebello and Barrow islands, and those of the Dampier Archipelago. At lowest sea level around 22 ka, these would have been uplands that then became progressively isolated by subsequent sea-level rise. By integrating archaeological and zooarchaeological records from excavations on these islands with the geology and geomorphology, we interpret palaeoeconomic resource potential in relation to changing sea level and coastline morphology. The preservation potential for submerged archaeological sites and features is also assessed. Current archaeological evidence from these offshore islands indicates that the submerged coastal landscape is likely to have been a potentially rich environment for resources and human occupation, even at times of lowest sea level and regional aridity. Should any exploration of submerged archaeology be carried out in this region, it is likely to be rewarding, offering unique insights into Late Pleistocene coastal occupation.
