Geoarchaeology on topographic undulations of Oceanic atolls.

Abstract

While atoll islets appear generally low and flat, there are topographic undulations in small scale, such as storm ridges piled up on ocean-side coast of some islets, beach ridges stretching on lagoon-side shoreline, and wet depressions between them. Focusing on sand dunes and agricultural pits among those undulations, we are presenting geoarchaeological studies for landscape history of interactions between two agencies, human and nature.
