At present, as much as 80% of the seafloor has yet to be mapped in detail. Even the Moon and Mars are mapped at a higher resolution than our own oceans.Dr. Vicki Ferrini wants to change that.  She is a marine geologist who specializes in bathymetry, the science of mapping underwater topography, and uses sonar to take measurements of water depth.  She uses these measuremen
