The role of organic aerosols in homogeneous ice formation [PDF]

, 2004
Kärcher B, Koop T. The role of organic aerosols in homogeneous ice formation. ATMOSPHERIC CHEMISTRY AND PHYSICS. 2005;5(3):703-714.Recent field observations suggest that the fraction of organic-containing aerosol particles in ice cloud particles is ...

Simulating higher-order fabric structure in a coupled, anisotropic ice-flow model: application to Dome C

Journal of Glaciology, 2023
Ice-crystal fabric can induce mechanical anisotropy that significantly affects flow, but ice-flow models generally do not include fabric development or its effect upon flow.

Reconstructing ice-sheet accumulation rates at ridge B, East Antarctica [PDF]

, 2004
Understanding how ice sheets responded to past climate change is fundamental to forecasting how they will respond in the future. Numerical models calculating the evolution of ice sheets depend upon accumulation data, which are principally available from ...

Ice nucleation under cirrus cloud conditions [PDF]

, 2012
Cirrus are thin upper tropospheric clouds that are composed entirely of ice particles. Due to their extensive coverage of the Earth’s surface, they have a significant impact on the Earth’s radiative balance.

A novel conceptual model for Dansgaard–Oeschger event dynamics based on ice-core data [PDF]

Climate of the Past
This study introduces a novel dynamical systems model designed to capture the highly non-periodic nature of Dansgaard–Oeschger (DO) events. Such events are difficult to model adequately due to their variable durations (some lasting around 1 century ...

Development of a low-temperature immersion microscopy technique for ice research

Annals of Glaciology, 2023
Perennial ice can be studied for many purposes, including paleoclimate records or rheological properties. For most of those purposes, the ice microstructure must be studied, often through optical microscopy.

Interplay of grounding-line dynamics and sub-shelf melting during retreat of the Bjørnøyrenna Ice Stream

Scientific Reports, 2018
The Barents Sea Ice Sheet was a marine-based ice sheet, i.e., it rested on the Barents Sea floor during the Last Glacial Maximum (21 ky BP). The Bjørnøyrenna Ice Stream was the largest ice stream draining the Barents Sea Ice Sheet and is regarded as an ...

Strengthening ice through cyclic loading

Journal of Glaciology, 2017
New experiments reveal that the flexural strength of fresh water, columnar-grained ice loaded normal to the columns may be increased by about a factor of two upon reversed cyclic loading at a frequency of ~0.1 Hz at stress amplitudes of 1.3–2.6 MPa.

Direct measurement of optical properties of glacier ice using a photon-counting diffuse LiDAR

Journal of Glaciology, 2022
The production of meltwater from glacier ice, which is exposed at the margins of land ice during the summer, is responsible for a large proportion of glacier mass loss.

Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]

, 2014
Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.
