Ocean tidal heating in icy satellites with solid shells

I Matsuyama, M Beuthe, HCFC Hay, F Nimmo… - Icarus, 2018 - Elsevier
As a long-term energy source, tidal heating in subsurface oceans of icy satellites can
influence their thermal, rotational, and orbital evolution, and the sustainability of oceans. We …

Brine migration and impact‐induced cryovolcanism on Europa

G Steinbrügge, JRC Voigt… - Geophysical …, 2020 - Wiley Online Library
Despite evidence for plumes on Jupiter's moon Europa, no surface features have been
definitively identified as the source of the plumes to date. Furthermore, it remains unknown …

Fracture, friction, and permeability of ice

EM Schulson, CE Renshaw - Annual Review of Earth and …, 2022 - annualreviews.org
Water ice Ih exhibits brittle behavior when rapidly loaded. Under tension, it fails via crack
nucleation and propagation. Compressive failure is more complicated. Under low …

Cooling crusts create concomitant cryovolcanic cracks

ML Rudolph, M Manga, M Walker… - Geophysical Research …, 2022 - Wiley Online Library
The orbital and internal evolution of the ice‐covered ocean worlds orbiting Jupiter and
Saturn are coupled, leading to time‐varying thicknesses of their ice shells. As the ice …

Cascading parallel fractures on Enceladus

DJ Hemingway, ML Rudolph, M Manga - Nature Astronomy, 2020 - nature.com
Active eruptions from the south polar region of Saturn's~ 500-km-diameter moon Enceladus
are concentrated along a series of lineaments known as the 'tiger stripes',, thought to be …

Strengthening of columnar-grained freshwater ice through cyclic flexural loading

A Murdza, EM Schulson, CE Renshaw - Journal of Glaciology, 2020 - cambridge.org
Systematic experiments reveal that the flexural strength of freshwater S2 columnar-grained
ice loaded normal to the columns increases upon cyclic loading. Specifically, over the range …

Influence of porosity on ice dynamic tensile behavior as assessed by spalling tests

D Georges, D Saletti, M Montagnat, P Forquin… - Journal of Dynamic …, 2021 - Springer
The impact of ice on structures is a strong concern, in particular for aeronautical or space
crafts that are strongly damaged by the impact of atmospheric ice, and more specifically by …

Frictional strength, stability, and potential shear heating on icy satellite faults

M Zaman, C McCarthy, RM Skarbek… - Journal of Geophysical …, 2024 - Wiley Online Library
We determined the frictional strength and stability of polycrystalline ice and ice‐ammonia to
constrain fault behavior on icy satellites such as Enceladus and Europa. Friction …

Obliquity, precession, and fracture mechanics: Implications of Europa's global cycloid population

AR Rhoden, KJ Mohr, TA Hurford… - Journal of …, 2021 - Wiley Online Library
We catalog the global inventory of Europa's cycloids, arcuate fractures whose paths have
been linked to diurnal tidal stress, and use the locations and orientations of their cusps to …

Relaxation of flexure‐induced strengthening of ice

A Murdza, EM Schulson… - Geophysical Research …, 2022 - Wiley Online Library
Increasing fetch as sea ice retreats with global warming is increasing the amplitude of ocean
waves, motivating the need for a better understanding of the impact of episodic flexing on …
