Exploring an Underground Sea

Senior engineer Tom Austin of the Oceanographic Systems Laboratory (OSL) steadies a custom-built REMUS autonomous underwater vehicle as it is raised off its storage platform. In 2003, the specially designed Tunnel Inspection Vehicle was deployed in a New York City aqueduct to help assess the structural integrity of the massive water-delivery system. The OSL team has been asked to make another survey for the city in 2008.
