Title

Underwater Survey at the Ruins of Nan Madol, Pohnpei State, Federated States of Micronesia

Description

In this paper we demonstrate the results of underwater survey at Nan Madol, Federated States of Micronesia. Nan Madol are the ruins of a megalithic civilization composed of 95 small to large artificial islets made mostly of basalt, situated on a shallow water of Pohnpei Island. The site is now on the Tentative List of the UNESCO World Heritage Site submitted by Federated States of Micronesia. Protection of the site is comprised of both these basaltic islets and the water surrounding them. In addition, there is an oral tradition that a sunken city named Kahnihmweiso is located underwater near the site. The goal of our investigation is to make a map of underwater topography that is expected to be utilized for the site documentation and the setting of core and buffer
zones. The investigation was carried out by using multi-beam sonar and a remotely operated vehicle (ROV), as well as manual survey by scuba diving gears. Research has revealed that there is no clear evidence of artificial constructions under the water; however, a detailed map of underwater topography around the site was obtained. Our research also stresses the significance of the sea area as a resource of legends and a component of the intangible cultural heritage of Nan Madol.
