Summary This paper gives a comparison of crossing‐arc techniques for reduction of test grids of satellite altimetry data. For this study, Seasat data was selected for two areas: the Eastern Mediterranean, an area which incorporates considerable variation in sea‐floor topography, and part of the North Atlantic. Three implementations of crossover‐point and repeat‐arc methods were considered, and evaluated for accuracy and speed of implementation. the sample geoids produced were found to contain significant differences, indicating that choice of reduction method can be an important criterion for consideration in such analyses.
