The Office of Coast Survey is the oldest U.S. scientific organization, dating from 1807 when Congress directed that a "survey of the coast" be carried out. By 1836, it was called the U.S. Coast Survey and in 1878, the name was changed to the U.S. Coast and Geodetic Survey. Today the Office of Coast Survey is a division of the National Oceanic and Atmospheric Administration NOAA.
The survey teams, composed of civilians as well as Army and Naval officers, charted the nation's waterways and produced a wide array of reports, survey charts, hydrographic studies of tides and currents, astronomical studies and observations, and coastal pilots. These charts are an important record of the changing nature of the nation's coastlines. In additional to coastal charts, the U.S. Coast and Geodetic Survey produced land sketches, Civil War battle maps, and the early aeronautical charts.
1) This coastal survey chart details the entrance to Galveston Bay. It includes a town plan of Galveston without streets named. The chart extends to Pelican Island, Bird Key, and Bolivar Point. It locates buoys, a beacon, a light boat, and is filled with soundings, bottom types, extensive notations on sailing directions, tides, etc. Triangulations were accomplished in 1848 by R.H. Fauntleroy and J.S. Williams. The topography was accomplished in 1849 and 1850 by J.M. Wampler, while the hydrography was under the direction of T. A. Craven and A. S. Baldwin in 1851 and 1852.
2) Handsome chart of the entrance to Galveston Bay, noting San Luis Island, Galveston and Mud Island as well as Peninsula Point. The chart notes soundings, sailing directions and tidal effects.
