In service 1960-1995. NOAA Ship Surveyor (S 132) worked in the Pacific Ocean from the Beaufort Sea to the Palmer Peninsula of Antarctica during its career. Known affectionately as "Old Workhorse" by those who served, this was the first NOAA ship equipped with a deep-water multi-beam echosounder. This ship conducted hydrographic surveys in areas ranging from Norton Sound Alaska to American Samoa. It was the primary ship for studying the Alaskan Arctic for the Outer Continental Shelf Environmental Assessment Program (OCSEAP) and the primary ship for studying Antarctic Marine Living Resources (AMLR.) It was the first NOAA ship equipped with a deep-water multi-beam system and conducted multi-beam surveys on the United States West Coast, off the southern coast of Alaska, throughout the Juan de Fuca Ridge area, and in Hawaiian waters. This ship is commemorated by Surveyor Fracture Zone, Surveyor Gap, and Surveyor Seachannel. It discovered Axial Seamount on Endeavor Ridge, a seamount that has apparently been split in half by seafloor spreading.
