USCS Robert J. Walker (1844)
USCS "Robert J. Walker" was a survey ship that served in the United States Coast Survey, a predecessor of the United States Coast and Geodetic Survey, from 1848 until sinking in 1860 after a collision at sea. Her loss resulted in the death of 20 men, the greatest loss of life in single incident ever to befall the National Oceanic and Atmospheric Administration or any of its ancestor agencies. Construction and acquisition. "Robert J. Walker" was a sidewheel steamer built in 1844 by Joseph Tomlinson at Pittsburgh, Pennsylvania, as one of the United States Governments  first iron-hulled steamers. She was among eight steamers originally intended for the United States Revenue Cutter Service, but the Revenue Cutter Service had decided that the steamers were too expensive to maintain and operate, and she instead entered Coast Survey service in 1848. Operational history. "Robert J. Walker"s first operations involved surveying the waters of Mobile Bay in 1848, and her first commanding officer, Carlile P. Patterson, reported that year on her performance and capabilities compared with those of sailing ships. "Robert J. Walker" spent the 1850s charting the waters of the United States Gulf Coast. She suffered deaths  among her crew in 1852 when two men—her second and third assistant engineers—died of disease during an epidemic along the Gulf Coast. On the night of 20 January 1858, "Robert J. Walker" was at Pensacola, Florida, when a major fire broke out at the United States Armys Fort Pickens. Her men and boats, along with the hydrographic party of the Coast Survey steamer , promptly assisted in fighting the fire. The next day, "Robert J. Walker"s commanding officer received a communication from Captain John Newton of the Army Corps of Engineers, commanding the harbor of Pensacola, acknowledging the important  firefighting service rendered by "Robert J. Walker". Loss. Early on the morning of 21 June 1860, "Robert J. Walker" had completed her most recent hydrographic survey work and was bound from Norfolk, Virginia, to New York City in rough seas with a crew of 72 and the wife of the executive officer on board. At 02:20, a commercial schooner, identified as "Fanny" by "Robert J. Walker"s crew, collided with her. She sank in less than 30 minutes in the Atlantic Ocean off the coast of New Jersey approximately 12 nautical miles (22 kilometers) southeast of Absecon Inlet Light, with a  loss of 20 men. It was the greatest disaster ever to occur in any ancestor agency of the modern-day National Oceanic and Atmospheric Administration (NOAA). The commercial schooner "R. G. Porter" came to "Robert J. Walker"s assistance, recovered her survivors, searched for her missing men, and brought the survivors into May's Landing, New Jersey, later in the day. "Fanny", meanwhile, arrived at Cape May, New Jersey, that day with damage consistent with a collision with "Robert J. Walker". With the American Civil War approaching, no inquiry into the cause of the "Robert J. Walker" disaster ever took place , and the Coast Survey did not pursue the matter of "Fanny"s presumed culpability in the sinking. No official ceremony in honor of the lost crewmen was held. Discovery of wreck. A commercial fisherman found the wreck of "Robert J. Walker" in the 1970s, off the New Jersey coast in of water, and divers visited it regularly thereafter, but it remained unidentified until 2013, when NOAA announced that a positive identification had been made. On 21 June 2013, the NOAA survey ship , operating in the area to conduct hydrographic surveys for navigation safety after Hurricane Sandy, held a wreath-tossing ceremony  in the general area of the wreck to honor "Robert J. Walker"s dead on the 153rd anniversary of her sinking – the first official commemorative ceremony ever held for them – then collected survey data using multibeam sonar and sidescan sonar later in the day that established with 80 percent certainty the identity and location of the wreck. A NOAA Maritime Heritage dive team, also in the area for post-Hurricane Sandy operations, confirmed the wrecks identity on 23 June 2013. NOAA used several key clues to confirm the identity of the ship including the size and layout of the iron hull , unique engines, and rectangular portholes. NOAA has no plans to raise the wreck, make it a sanctuary, or limit diving to it, but does plan to work with the New Jersey diving community to increase understanding of the wreck.
