Estimation of the ocean geoid near the Blake Escarpment using GEOS-3 satellite altimetry [PDF]
The accuracy with which the local ocean geoid structure could be determined using satellite altimetry data was investigated. The undulation and along-track component of the vertical deflection for selected passes of GEOS-3 near the Blake Escarpment were ...
