Mission scientist Grace Young, left an MIT graduate in Mechanical & Ocean Engineering, Ryan Stancil, center, Mission doctor, and Fabien Cousteau chat inside Aquarius Reef Base, a laboratory 63 feet below the surface in the waters off Key Largo, in the Florida Keys National Marine Sanctuary, Tuesday, June 24, 2014. A team of filmmakers and researchers dove with Cousteau on June 1 to Aquarius. At the mission's mid-point, the FIU researchers traded places with researchers from Northeastern, who will return to land July 2 with Cousteau. They've been studying the effects of climate change and pollutants such as fertilizers on the reef. (AP Photo/Wilfredo Lee)
