Project Overview

The discovery of an onshore cave in Aceh Province, Indonesia, that preserves a sequence of marine-origin sand layers (possibly palaeo-tsunami in origin) interspersed by guano has given rise to an interesting application of thin-bed ground penetrating radar techniques.

This collaborative project between Syiah Kuala University, National University of Singapore, University of Pennsylvania, British Geological Survey, James Cook University and the Earth Observatory of Singapore and Division of Earth Sciences at Nanyang Technological University, will attempt to investigate the sub-surface bedding characteristics of these deposits to glean more information of their mode of formation and pinpoint specific areas where more invasive techniques can be applied.
