During its first two years in operation, the DSSV Pressure Drop collected more than 1 million km2 of deep sea bathymetric data from some of the deepest places in the world in support of manned-submersible dives and scientific exploration. The four major expeditions within these two years identified several new seafloor features and species of deep sea life, dived a manned-submersible more than 25 times to the world's deepest depths, and performed more than 100 scientific lander deployments. Highlights from the bathymetric data, scientific lander videos, and stories from the expeditions will be shared. 


Cassie Bongiovanni got her B.S. in Geology with a focus in Oceanography at the University of Washington in Seattle. While there, she spent time aboard both UW research vessels working with multibeam data. Cassie then spent a couple of years working with NOAA’s Integrated Ocean and Coastal Mapping group on processing outside source acoustic data for its post-Hurricane Sandy research efforts. Cassie received her M.S. in Ocean Mapping at University of New Hampshire and, shortly after, led the mapping efforts aboard the DSSV Pressure Drop during the Five Deeps, Calypso, Red Sea, and Ring of Fire 1 Expeditions. Currently, Cassie leads a small team of mapping experts at the Applied Research Laboratories at the University of Texas.
