Numerical modeling of the global semidiurnal tide in the present day and in the last glacial maximum
TL;DR: In this article, a hydrodynamic model incorporating a self-consistent treatment of ocean selfattraction and loading (SAL), and a physically based parameterization of internal tide (IT) drag, is used to assess how accurately barotropic tides can be modeled without benefit of data, and to explore tidal energetics in the last glacial maximum (LGM).
Journal ArticleDOI
Assessment of ICESat performance at the salar de Uyuni, Bolivia
Helen A. Fricker,Adrian A. Borsa,B. Minster,Claudia C. Carabajal,Katherine J. Quinn,Bruce G. Bills +5 more
TL;DR: In this paper, the authors used a GPS-derived digital elevation model (DEM) of the salar de Uyuni, Bolivia for this purpose and showed that the accuracy of ICESat-derived elevations is impacted by environmental effects and instrument effects (e.g., pointing biases, detector saturation, and variations in transmitted laser energy).
Journal ArticleDOI
Eruptions arising from tidally controlled periodic openings of rifts on Enceladus
TL;DR: A mechanism in which temporal variations in tidal stress open and close the tiger-stripe rifts, governing the timing of eruptions is reported, implying that Enceladus’ icy shell behaves as a thin elastic layer, perhaps only a few tens of kilometres thick.
Journal ArticleDOI
Viscosity estimates for the crust and upper mantle from patterns of lacustrine shoreline deformation in the Eastern Great Basin
TL;DR: In this article, the authors describe and apply a new model to a recently augmented data set to better constrain both the complex spatio-temporal pattern of the lake load and the crustal deformation response to that load.
Journal ArticleDOI

TL;DR: The current state of Mars polar research is assessed, the key questions that motivate the exploration of the polar regions are identified, the extent to which current missions will address these questions are discussed, and what additional capabilities and investigations may be required to address the issues that remain outstanding are speculated.
