On the More Complex Wavelength Dependency of Airy Isostasy in Icy Shells of Ocean Worlds
Geophysical Research Letters, 2023 AbstractThe topography of ocean worlds is often used to infer ice shell thicknesses by assuming topography is compensated by a basal root. We systematically test the stability of isostatically compensated topography in ice shells. At short horizontal wavelengths, lithospheric strength can support surface topography, while at long wavelengths, buoyancy ...

Isostasy with Love: II Airy compensation arising from viscoelastic relaxation [PDF]
Geophysical Journal International, 2021 SUMMARYIn modern geodynamics, isostasy can be viewed either as the static equilibrium of the crust that minimizes deviatoric stresses, or as a dynamic process resulting from the viscous relaxation of the non-hydrostatic crustal shape. Paper I gave a general formulation of Airy isostasy as an elastic loading problem solved with Love numbers, and applied

Is Airy Isostasy Applicable to Icy Moons?
Geophysical Research Letters, 2019 AbstractAiry isostasy is commonly used in planetary science to explain the relationship between crustal thickness variations and topography. Recently, several researchers have questioned the validity of this concept and proposed alternative approaches. Here we examine the accuracy of these approaches by comparing their results with those obtained from ...

Geochemistry, Geophysics, Geosystems, 2020 The observed variations in the thickness of the conductive lithosphere, derived from surface wave studies, have a first‐order control on the elevation of the continents, in addition to variations in the thickness of the crust—this defines whole ...

The Role of Isostasy in the Evolution and Architecture of Fold and Thrust Belts
Lithosphere, 2023 Warmer conditions prevalent in the hinterland of orogenic systems facilitate local ductile flow underneath the surface load, making Airy-like local isostasy more prevalent in these domains.

Gravity‐Derived Antarctic Crustal Thickness Based on the Gauss‐FFT Method
Geochemistry, Geophysics, Geosystems, 2022 The information on crustal thickness in Antarctica can provide significant constraints on its crustal deformation and tectonic evolution. To generate reliable images of crustal features, we investigate the model of Moho depth and crustal thickness ...

Earth, Planets and Space, 2021 Lithospheric deformation is a fundamental process in plate tectonics. It is, therefore, critical to determine how the lithosphere responds to geological loads to better understand tectonic processes.

Remote Sensing, 2020 The present study deals with the morphometric quantification of erosion and illustrates the uplift component triggered by denudation (isostasy) in the growth and evolution of a rising orogeny by the application of Airy isostasy concepts.

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]
, 2008 Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.
