Take a rare behind-the-scenes look at an oceanographic research expedition in action during a 30-minute live link with scientists who are exploring the wreck of the steamship PORTLAND, which lies on the seafloor of NOAA's Stellwagen Bank National Marine Sanctuary in Massachusetts Bay. Scientists aboard the RESEARCH VESSEL (R/V) CONNECTICUT and the vessel DAWN TREADER is conducting biological and archaeological surveys of some of the sanctuary's most iconic shipwrecks and comparing these to life on natural hard-bottom habitats elsewhere on the bank. NOAA's Office of National Marine Sanctuaries has teamed up with Woods Hole Oceanographic Institution (WHOI) and Marine Imaging Technologies on this interdisciplinary expedition, which employs a variety of innovative marine technologies including Pixel, a cinema class remotely operated vehicle (ROV) and Rover, an ROV equipped to collect samples from the seafloor. Alice Stratton, marine ecologist for the sanctuary, will be on hand to introduce the programs and answer questions. Offered twice at 12:30 and 3 pm.
