Dr. Andy Hemmings and Cliff Brown are diving in attempts to collect samples. Dr. Hemmings attempts to take a core from depth and subsequently takes surface samples with Cliff Brown's help. Cliff Brown swims off on a perimeter check for potential other sites, while Dr. Hemmings hand-fans, digs, and hammers out a sample. Video courtesy of Exploring the Submerged New World 2009 Expedition.
