This report is significant for the survey results reported on the Gulf Stream and the discovery of the "cold wall" between the Stream and the coast. NOAA calls the Gulf Stream survey "a project that heralded the beginnings of modern oceanography". Also notable is the detailed report of the hurricane that swept Lt. George Bache and ten of his crewmen overboard on September 8, 1846 while sailing past Virginia. Lt. Bache headed the Gulf Stream exploration and was the brother of Alexander Bache, Superintendent of the Coast Survey. The surviving Bache writes sadly in this report, "Of the loss I cannot trust myself to speak." (p. 23.) 74 pages with 9 charts. The sketches and triangulations cover the Northeast, Massachusetts, Long Island, Delaware Bay, Great Egg Harbor, also Mississippi Sound. Disbound.
