Community Geothermal: Geothermal Heat Exchange Test Well Temperature, Conductivity, and Water Level Data - Seward, AK

This dataset contains temperature, conductivity, and pressure data collected from a geothermal test well in Seward, Alaska, from October 31, 2023, through May 14, 2024. The data from the sensors are used to assess the potential for geothermal heat exchange along the shoreline of the nearby Resurrection Bay. Project materials below include the raw and processed data, a data collection summary report, as well as detailed information on the sensors used.

Resurrection Bay remains naturally warm during the winter heating season due to ocean currents that carry warm equatorial waters to the bay during the summer. The temperature of the bay decreases from a summertime high of about 50-37 degrees F over the winter season. As such, the bay remains free of ice all year long. In addition, the shoreline is a deep alluvial gravel bed which allows tidal waters to flush through the shoreline, as well as fresh groundwater from the surrounding mountains to flow through into the bay. Given these unique conditions, the bay and the permeable shoreline present a favorable opportunity for geothermal heat exchange, and can be used to provide heating through a geothermal heat pump system.
