Harvard Mine is a pit mine in Northern California, flooded to over 500 feet deep and counting. A natural spring was struck at the mine's bottom and the inflow of water soon became uncontrollable. This flooding continues to this day, with the surface of the flooded area measuring 70 acres. The Aquanaut Program has established an ROV training program for children at the mine. As part of the program the mine will serve as a Project Baseline project, with students using ROVs to take water samples and measure arsenic levels at various depths, among other tasks.

Project Baseline has been at the forefront of increasing awareness of Florida reef decline as well as monitoring the health index for nearly 70 marine and freshwater environments world-wide since 2009.
