Learning the ropes aboard a NOAA hydrographic survey vessel

By Natalie Cook

University of New Hampshire’s Center for Coastal and Ocean Mapping and NOAA are giving undergraduate students the opportunity to participate in seafloor mapping and associated exercises aboard a survey vessel this summer. Natalie Cook, a junior in the Ocean Engineering program, is spending eight weeks aboard NOAA Ship Thomas Jefferson, a 208-foot hydrographic survey vessel, experiencing all aspects of hydrography. Natalie is standing survey watch, processing data, working on survey launches, and serving as an active member of the hydrographic survey team.
