Galerkin Least-Squares Stabilization in Ice Sheet Modeling - Accuracy, Robustness, and Comparison to other Techniques [PDF]
J. Comput Geosci (2018) 22: 951, 2017 We investigate the accuracy and robustness of one of the most common methods used in glaciology for the discretization of the $\mathfrak{p}$-Stokes equations: equal order finite elements with Galerkin Least-Squares (GLS) stabilization. Furthermore we compare the results to other stabilized methods.

The generalized Clapeyron equation and its application to confined ice growth [PDF]
, 2023 Most theoretical descriptions of stresses induced by freezing are rooted in the (generalized) Clapeyron equation, which predicts the pressure that a solid can exert as it cools below its melting temperature. This equation is central for topics ranging beyond glaciology to geomorphology, civil engineering, food storage, and cryopreservation. However, it

Stable water isotopes and the physical environment
Belgeo, 2002 This paper presents the characteristics of the fractionation of water isotopes which occurs during evaporation and freezing of water. It shows how these characteristics can be used for studying some aspects of the physical environment, namely ...

Remote Detection of Surge-Related Glacier Terminus Change across High Mountain Asia
Remote Sensing, 2021 High Mountain Asia (HMA) hosts the largest glacier concentration outside of polar regions. It is also distinct glaciologically as it forms one of two major surge clusters globally, and many glaciers there contradict the globally observed glacier ...

Inland thinning of the Amundsen Sea sector, West Antarctica [PDF]
, 2002 [1] Together with the Pine Island glacier (PIG), the Thwaites (TG) and Smith (SG) glaciers are the principal drainage systems of the Amundsen Sea (AS) sector of Western Antarctica.

Boreas, Volume 52, Issue 1, Page 60-77, January 2023., 2023 Credible historical land use/cover data are very important for past global change research. This study generates a set of integrated reconstruction methods based on multisource data and produces a new set of improved historical cropland data sets in Europe over the past 200 years.

Distributed Parallelization of xPU Stencil Computations in Julia [PDF]
arXiv, 2022 We present a straightforward approach for distributed parallelization of stencil-based xPU applications on a regular staggered grid, which is instantiated in the package ImplicitGlobalGrid.jl. The approach allows to leverage remote direct memory access and enables close to ideal weak scaling of real-world applications on thousands of GPUs.

Dynamics of Crystal Formation in the Greenland NorthGRIP Ice Core [PDF]
J. Glaciology 50, 325 (2004), 2003 The North Greenland Ice Core Project (NorthGRIP) provides paleoclimatic information back to at about 120 kyr before present (Dahl-Jensen and others, 2002). Each year, precipitation on the ice sheet covers it with a new layer of snow, which gradually transforms into ice crystals as the layer sinks into the ice sheet.

Boreas, Volume 52, Issue 1, Page 124-138, January 2023., 2023 Tierra del Fuego in Argentina is a unique location to examine past Holocene wind variability since it intersects the core of the Southern Hemisphere Westerly Winds (SHWW). The SHWW are the most powerful prevailing winds on Earth. Their variation plays a role in regulating atmospheric CO2 levels and rainfall amounts and distribution, both today and in ...
