Description:

Abstract:

This dataset shows the general geology of Pohnpei. It was created by Island Research & Education Initiative (iREi) (2017) by scanning, georeferencing, and digitizing a paper map prepared by the U.S. Geological Survey (1944) for the Chief of Engineers, U.S. Army as part of the Strategic Engineering Study No. 109 titled Ponape including Pakin and Ant Islands (Carolines) Terrain Intelligence. The map was found in the library collection at the national campus of the College of Micronesia (COM). It should be noted that this map is very general and erroneously identifies areas in Sokehs and Nett as being composed of raised reef rock.

Purpose: To show the general geology of Pohnpei.

Supplemental_Information:

The dataset is included the Digital Atlas of Micronesia, module Pohnpei, by Island Research & Education Initiative (iREi), in collaboration with Water and Environmental Research Institute of the Western Pacific (WERI) University of Guam and partial funding from United States Geological Survey (USGS), under WRRI 104-B Program, project # 2016GU302B.
