Global marine gravity from retracked Geosat and ERS-1 altimetry: Ridge segmentation versus spreading rate

David T. Sandwell, Walter H. F. Smith
2009 Journal of Geophysical Research  
Second, we have used the recently published EGM2008 global gravity model as a reference field to provide a seamless gravity transition from land to ocean.  ...  Comparisons between shipboard gravity and the global gravity grid show errors ranging from 2.0 mGal in the Gulf of Mexico to 4.0 mGal in areas with rugged seafloor topography.  ...  This is a worst case error estimate from the ''ABYSS'' proposal to use the International Space Station.  ...

Chapter 3 Physical setting [chapter]

2003 Developments in Quaternary Sciences  
Because distance in degrees of longitude is not constant, oceanographers measure distance on maps using degrees of latitude. Nautical miles and meters are connected historically to the size of Earth.  ...  For careful work, remember that Earth is not a sphere, and latitude varies slightly with distance from the equator. The values listed here are close enough for our discussions of the oceans.  ...  Satellite Altimeter Maps of the Bathymetry Seasat, geosat, ers-1, and ers-2 were operated in orbits designed to map the marine geoid.  ...

2020 Frontiers in Marine Science  
Satellite altimeters provide continuous information of the sea level variability and mesoscale processes for the global ocean.  ...  The prerequisite for the computation of a coastal MDT, using the newly available data of surface velocities, was to obtain a robust methodology to remove the ageostrophic signal from the HF radar measurements  ...  For the first months of the SWOT mission (both for the 1-day and 21-day orbits), a challenge will be to validate the products, especially in coastal areas.  ...
