The R/V Robert D. Conrad, owned by the U.S. Navy and operated under charter by Lamont-Doherty Geological Observatory (L-DGO) of Columbia University for twenty-six years, had long been one of the premier ships for marine geology and geophysics (MG&G) within the University-National Oceanographic Laboratory System (UNOLS) fleet. During this period the R/V Conrad carried numerous major research expeditions and sailed 1.25 million miles. Only one other vessel, the R/V Vema, owned by Columbia University and retired in 1981, has surpassed the million mile research mark.
