The Mean Sea Level of the Gulf Stream Estimated from Satellite Altimetric and Infrared Dataapproximately 6.7 km every second. Such sampling has yielded unprecented coverage in deep water where tide gages cannot be placed and in ocean regions where weather discourages ship presence, at a rate 1400 times faster than a ship carrying a gravimeter (although the satellite has somewhat less alon

Strategies for Solving the Vertical Datum Problem Using Terrestrial and Satellite Geodetic Datalevelling lines. Since levelling is a relative operation some vertical datum must be fixed in order to determine “absolute” heights of benchmarks. In most cases the vertical datum of a height network has been defined by assigning zero height to the long-term mean value of local sea level observed at

The Determination of Mean Sea Level Using GPSh, and the Proudman Oceanographic Laboratory, in conjunction with the Ordnance Survey of Great Britain, began an investigation into the apparent discrepancy between geodetic and oceanographic methods of levelling. This discrepancy is manifested as a sea slope in a north-south direction around the co

A General Ocean Circulation Model Determined in a Simultaneous Solution with the Earth’s Gravity Fie of a technique which simultaneously solves for the sea surface topography, the gravity field of the Earth, and the satellite orbit [..,1988; .., 1989; .,1989; .; 1989]. The sea surface topography, ., is defined as the deviation of the ocean surface from the geoid due to the geostrophic component of
