Over the past 15 years, software for processing interferometric synthetic aperture radar (InSAR) data into maps of surface deformation has been developed and refined. The InSAR technique is commonly used to investigate deformation associated with earthquakes, volcanoes, withdrawal of crustal fluids, and coherent ice motions [Massonnet and Feigl, 1998]. The(More)
[1] A long-standing question in geodynamics is the cause of deviations of ocean depth or seafloor topography from the prediction of a cooling half-space model (HSC). Are the deviations caused entirely by mantle plumes or lithospheric reheating associated with sublithospheric small-scale convection or some other mechanisms? In this study we analyzed the age(More)
The article by Wessel et al. [this issue] highlights the need for a systematic mapping of the seamounts in the ocean basins. They estimate that 100,000 or 90% of the seamounts greater than 1 km tall are unobserved by either ship soundings or satellite gravity. There are two reasons why most of these relatively large predicted seamounts remain uncharted.(More)
