A new archaeological field survey of the site of Nan Madol, Pohnpei

Nan Madol, sometimes called the ‘Venice of the Pacific,’ is a mortuary and administrative site built from columnar basalt, boulders, and coral. It is made up of artificial islets that stretch over 83 hectares of lagoon on the volcanic high island of Pohnpei in the Federated States of Micronesia and is pivotal to our understanding of ancient Pohnpeian society. Nan Madol was first mapped in its entirety in 1910 by the German explorer Paul Hambruch and in the century since then the site has been re-surveyed and maps of varying levels of detail have been published. Here we report on the first full coverage field survey of the site’s artificial islets employing high precision GPS. The survey dataset has been made available for download as a Geographic Information Systems (GIS) layer at the data clearinghouse website: The Digital Archaeological Record (tDAR). We also report a matching annotated list of variant place names used in the literature and some brief information on the function of islets from oral traditions. This report, the digital map, and the annotated list of islets are aimed to provide future researchers with a baseline database.
