Marine geodesy

Abstract

Marine geodesy is generally understood to cover the extension of the principles and practices of land geodesy to the ocean areas of the world, but no agreement yet exists as to its exact scope. Recognition of marine geodesy as a distinct branch of geodesy in the United States can be traced to the First Marine Geodesy Symposium in Columbus, Ohio. A review of the proceedings of both the First Marine Geodesy Symposium and the Second Marine Geodesy Symposium held in New Orleans in 1969 and of meeting sessions described as marine geodesy sessions reveals that the following five primary subjects have been covered: needs and requirements for marine geodesy, establishment of control points on the ocean floor, determination of the oceanic geoid by surface methods, use of a satellite altimeter to determine the geometry of the ocean surface, and methods of ship positioning.
