Oceanic geoid and tides derived from GEOS 3 satellite data in the Northwestern Atlantic Ocean
Two sets of GEOS 3 altimeter data which fall within about a 2.5-deg width are analyzed for ocean geoid and tides. One set covers a path from Newfoundland to Cuba, and the other a path from Puerto Rico to the North Carolina coast. Forty different analyses using various parameters are performed in ord...
