- Summary:
- Located in the Waiau cone near the summit of an inactive volcano that is on the island of Hawaii, known as Mauna Kea, sits Lake Waiau where the existence of a negative thermal gradient under this lake has been determined. While the cause of the anomalous gradient remains uncertain, the answer is contingent upon the knowledge of the differences in the relative thermal properties of the lake water, sediment, cinders, and the lava that surrounds the lake as well as the thermal regime that has been established in the area through natural processes. As a result, this study was done in an effort to determine the thermal conductivity of the lake sediments in which the negative thermal gradient occurs. This would allow for scientists to obtain an estimate of the heat flux through the sediments.
