The Liquidus Temperature for Methanol-Water Mixtures at High Pressure and Low Temperature, with Application to Titan [PDF]
, 2018 Methanol is a potentially important impurity in subsurface oceans on Titan and Enceladus. We report measurements of the freezing of methanol-water samples at pressures up to 350~MPa using a volumetric cell with sapphire windows. For low concentrations of

Rheology of Discrete Failure Regimes of Anisotropic Sea Ice [PDF]
Journal of Physical Oceanography, 2012 ABSTRACT A rheological model of sea ice is presented that incorporates the orientational distribution of ice thickness in leads embedded in isotropic floe ice. Sea ice internal stress is determined by coulombic, ridging and tensile failure at orientations where corresponding failure criteria are satisfied at minimum stresses. Because sea

Ice geometry and thermal regime of Lyngmarksbræen Ice Cap, West Greenland
Journal of Glaciology, 2023 AbstractObservations remain sparse for peripheral glaciers and ice caps in Greenland. Here, we present the results of a multi-frequency radar survey of Lyngmarksbræen Ice Cap in West Greenland conducted in April 2017. Radar measurements show thick ice of up to ~120 m in subglacial valleys associated with the largest outlet glaciers, while relatively ...

Hysteretic evolution of ice rises and ice rumples in response to variations in sea level [PDF]
The Cryosphere, 2022 Ice rises and ice rumples are locally grounded features found in coastal Antarctica and are surrounded by otherwise freely floating ice shelves. An ice rise has an independent flow regime, whereas the flow regime of an ice rumple conforms to that of the ...

Dynamics of Topological Excitations in a Model Quantum Spin Ice
, 2018 We study the quantum spin dynamics of a frustrated XXZ model on a pyrochlore lattice by using large-scale quantum Monte Carlo simulation and stochastic analytic continuation.

Influence of meteorological conditions on the formation of ice regime of the Lake Onega
Лëд и снег, 2019 The formation of the ice regime on large lakes is mostly determined by the complex meteorological processes occurring over the water area. Previous studies of the air temperature influence on the ice regime formation on the Lake Onega were based on ...

Orientational Defects in Ice Ih: An Interpretation of Electrical Conductivity Measurements
, 2005 We present a first-principles study of the structure and energetics of Bjerrum defects in ice Ih and compare the results to experimental electrical conductivity data. While the DFT result for the activation energy is in good agreement with experiment, we

3D climate modeling of close-in land planets: Circulation patterns, climate moist bistability and habitability [PDF]
, 2013 The inner edge of the classical habitable zone is often defined by the critical flux needed to trigger the runaway greenhouse instability. This 1D notion of a critical flux, however, may not be so relevant for inhomogeneously irradiated planets, or when ...
