In May and September 2019, Mote scientists and partners undertook their deepest explorations to-date into the Gulf of Mexico's blue holes, underwater caves, springs and sinkholes that attract diverse marine life. The team deployed a “benthic lander”—a framework holding multiple scientific instruments collectively weighing more than 600 pounds—into the offshore Amberjack Hole, whose bottom extends deeper than 350 feet. In this episode of Two Sea Fans, Mote scientists Dr. Emily Hall and Jim Culter share what the team discovered inside this deep, dark and fascinating blue hole. Tune in to hear what they learned!
