The Great Lakes contain 90% of the United States' surface fresh
water over half of that water is contained in Lake Superior
alone. The Iver Three is an autonomous underwater vehicle
that we use to collect data about the biological,
geological, and physical processes taking place below
the surface. The Iver Three can go on missions for up to eight
hours and dive to 100 meters, gathering data and images that
we analyze in the lab. The more we understand about underwater
ecosystems, the better we can protect and preserve all of
Earth's hydrosphere for future generations.
