Abstract

Description

Profiles of along-track deflection of the vertical obtained from Seasat altimetry data show the changes in the slope of the surface of the sea. These changes in slope represent changes in the topography of the sea floor. The signatures of the waveforms in the profiles, while not unique, can be used to interpret the presence of ocean floor features such as seamounts (Sandwell, 1984). In this study, we have used the Seasat data, which we divided according to GEBCO windows (Fig. 1), to locate fracture zones which we will be incorporating into plate tectonic reconstructions.
