Conductivity, temperature, and depth (CTD). These three measurements allow scientists to unlock ocean patterns hidden beneath the sea's surface. The ocean is not uniform, it its filled with swirling eddies, temperature boundaries, layers of high and low salinity, changing densities, and other physical characteristics invisible to an observer floating upon its surface. To reveal these patterns oceanographers employ a CTD--an oceanographic instrument that, at its core, measures temperature, salini
