“…Time variations in sea height that are caused by dy namic mesoscale phenomena can therefore be detected in groups of collinear profiles. Longer-wavelength components caused by deep ocean tides, large-scale circulation, and orbit error can be removed by fitting segments of passes to each other along arcs of several thousand kilometers, per mitting computation of the rms variability along the track [Gordon and Baker, 1980;Byrne and Pullen, 1981;Doug las and Cheney 1981].…”

The last decade in oceanography has seen rapid advances in both in situ and remote instrumentation which have provided new insight into the physics of the sea. Satelliteborne instruments have been especially valuable in revealing complexities of the surface layer through infrared and multispectral imagery, precise global tracking of surface drifter fields, altimetric measurements of sea surface height, and radar observations of wind and wave patterns. This flood of information has opened new avenues of research and, in so doing, has significantly altered some of our conceptions of the general oceanic circulation. With improved observational techniques has come an appreciation of the highly variable nature of oceanic phenomena. This variability occurs on a wide range of scales, from microstructure to basinwide events, but particular attention has been directed toward the mesoscale. Current meanders, ring vortices, and midocean eddies comprise the ocean mesoscale variability, collectively known as the eddy field. The existence of oceanic eddies is not surprising, considering their well‐documented counterparts, the storms and weather patterns of the atmosphere. Yet their role in the maintenance of the general circulation is far from clear, and numerous expeditions have been dedicated to their exploration. Because these eddying motions often contain energy significantly greater than the mean flow itself, determination of eddy intensity and distribution is a necessary key to understanding global ocean dynamics.

“…Their results are based on data available from ships of opportunity, not from planned oceanographic experiments. Byrne and Pullen [1981] have shown that significant oceanographic changes occur within the 3-day spacing of the SEASAT repeat-orbit period.

“…Cheney [1982] has compiled much of this surface truth data in a series of biweekly maps for the Gulf Stream area. Byrne and Pullen [1981] have shown that significant oceanographic changes occur within the 3-day spacing of the SEASAT repeat-orbit period. Surface truth coincident in time and space with individual altimeter overpasses is necessary to determine the accuracy of altimetric data for measuring surface topography.…”

During the SEASAT repeat‐orbit period, a CTD and deep (1800 m) XBT hydrographic experiment was conducted across the Kuroshio to obtain cotemporaneous surface topography measurements for comparison with the altimeter‐derived surface height measurements. The results showed that the altimeter could detect and measure the change in sea surface topography caused by movement of the Kuroshio and the cold rings that were found in the hydrographic data. After compensation for the small differences in the time of the measurements, the altimeter measured changes in the surface topography that matched those measured by the hydrographic sections with an average difference of 9.6 cm for the 41 comparison points.
