We are hoping to explore non-contact hydrology techniques, and have landed on the use of seismic signals as one of our data sources. My hope is to use one buried unit full-time for the next three years, and an array of temporary nodes during the warmer months where the ground is more accessible. The buried unit would be located just above the trimline of the Nisqually River near Longmire WA, and the nodes would be distributed in strategic locations proximal to the Nisqually River within the boundaries of Mount Rainier National Park.
