“The scientists charting the world’s seafloors have come a long way from the days when sailors would head out on ships and tie a lead sinker to a line to measure ocean depths.
“The use of rapid-fire sonar technologies and computer programs developed at the University of New Hampshire has revolutionized seafloor mapping and drastically improved the accuracy of nautical charts.
“And while the science behind it is complicated, former UNH graduate student and research ship commander Shepard Smith said his days out on a hydrographic survey vessel provide the data necessary to create “road maps for the ocean.”"
