Descr: This is a combined teaching and research study of the groundwater system on Nantucket Island. The research element is in support of a project by Mark Person to understand the ground water sytem on Nantucket Island. Previous work revealed surprising volumes of fresh water under the island that have been hypothesized to be present due to recharge by glaciers in the last ice age. Regional well control, as always, is sparse and the project is designed to use geophysical methods to extend borehole measurements with the aim of producing an improved map of the ground water system. The experiment planned here is a pilot study being done on a shoestring budget. It combines a teaching element be serving simultaneously as a field training exercise for students in hydrogeology and geophysics for graduate students in our program. Most of the field workers will be students involved in a course planned around this experiment. The equipment will actually be used in two places. First, it will be used near Bloomington in support of a senior level geophysics class in introductory geophysics. This experiment will take place within the last two weeks of April. In summer session 1, mid-May 2002, we plan this field course on Nantucket Island. We will take the equipment from Bloomington, IN, to Nantucket by car. On the island we will collect one or two high resolution reflection lines from the south shore of the island inward connecting with existing monitoring wells.
