DESCRIPTION                                                             
     Abstract:     This data file contains hydrographic data from the National Ocean Survey
     including corrected soundings, bottom characteristics and dangers to
     navigation.  The data were digitized from hydrographic survey smooth sheets
     from surveys conducted between 1930 and 1965. Surveys completed after 1965 are
     incorporated into the data base as they are received.  Data are available for
     most of the coastal waters of the United States including the Great Lakes,
     Hawaii, Alaska and Puerto Rico.  Sounding density generally increases as water
     depth and distance from shore decrease.  The tidal data used are:
     
     Atlantic--mean low water; Gulf of Mexico--low water datum; Pacific--mean lower
     low water; Hawaii--mean lower low water; Alaska--mean lower low water; Great
     Lakes--low water datum.  Data are archived under entry ID FE00125; data
     inventories are archived under entry ID FE00125B.
