Use of magnetic methods in the investigation of an ancient Hawaiian fishpond: `Aimakapa`a Fishpond, Hawai`i
Duarte K and Kauahikaua J. 1999. Use of magnetic methods in the investigation of an ancient Hawaiian fishpond: `Aimakapa`a Fishpond, Hawai`i. U.S. Geological Survey (USGS) Open-File Report. 99-515
Magnetic methods were used at `Aimakapa`a fishpond on the island of Hawai`i to look for a stone seawall, or kuapa, that may be buried beneath a sand berm. The study was also aimed at searching for the fishpond's inlet channels, `auwai kai. Magnetic methods should show the location of magnetic basaltic rocks beneath relatively non-magnetic calcareous sand. Results indicate that there is no wall under the existing sand berm. In addition, magnetic profiles verify the location of the fishpond's one visible `auwai, reveal a possible second one, and suggest the possibility of other buried rock structures.
