Tour the Knorr - The research vessel used to discover Titanic and the hydrothermal vents

Are you fascinated by the RMS Titanic? How about hydrothermal vents? If one or both piqued your curiosity, you are invited to Tour the Knorr, the Woods Hole Oceanographic Institution research vessel used to discover the Titanic and hydrothermal vents (whatever they are). There are presentations and displays, and tours involve climbing several flights of narrow stairs.--June Wulff, Globe Staff
