Antarctic Sea Ice Area in CMIP6
Geophysical Research Letters, 2020 Fully coupled climate models have long shown a wide range of Antarctic sea ice states and evolution over the satellite era. Here, we present a high‐level evaluation of Antarctic sea ice in 40 models from the most recent phase of the Coupled Model ...

ASTER-Derived High-Resolution Ice Surface Temperature for the Arctic Coast
Remote Sensing, 2018 Ice surface temperature (IST) controls the rate of sea ice growth and the heat exchange between the atmosphere and ocean. In this study, high-resolution IST using the Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER) thermal infrared

Microplastics in sea ice and seawater beneath ice floes from the Arctic Ocean
Scientific Reports, 2020 Within the past decade, an alarm was raised about microplastics in the remote and seemingly pristine Arctic Ocean. To gain further insight about the issue, microplastic abundance, distribution and composition in sea ice cores (n = 25) and waters ...

Robust Mosaicking of Lightweight UAV Images Using Hybrid Image Transformation Modeling
Remote Sensing, 2020 This paper proposes a robust feature-based mosaicking method that can handle images obtained by lightweight unmanned aerial vehicles (UAVs). The imaging geometry of small UAVs can be characterized by unstable flight attitudes and low flight altitudes ...

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 Static and kinetic friction play a fundamental role in sea-ice mechanics. The coefficient of static friction increases with hold time under normal load and is modelled in terms of creep and fracture of asperities in contact. The coefficient of kinetic friction exhibits velocity strengthening at lower speeds and velocity weakening at intermediate speeds.

Geographic muting of changes in the Arctic sea ice cover [PDF]
, 2010 The seasonal cycle in Arctic sea ice extent is asymmetric. Its amplitude has grown in recent decades as the ice has retreated more rapidly in summer than in winter.

Active subglacial lakes and channelized water flow beneath the Kamb Ice Stream [PDF]
The Cryosphere, 2016 We identify two previously unknown subglacial lakes beneath the stagnated trunk of the Kamb Ice Stream (KIS). Rapid fill-drain hydrologic events over several months are inferred from surface height changes measured by CryoSat-2 altimetry and indicate ...

Effects of Wave-Induced Sea Ice Break-Up and Mixing in a High-Resolution Coupled Ice-Ocean Model
Journal of Marine Science and Engineering, 2021 Arctic sea ice plays a vital role in modulating the global climate. In the most recent decades, the rapid decline of the Arctic summer sea ice cover has exposed increasing areas of ice-free ocean, with sufficient fetch for waves to develop.

Prediction of Arctic Sea Ice Concentration Using a Fully Data Driven Deep Neural Network
Remote Sensing, 2017 The Arctic sea ice is an important indicator of the progress of global warming and climate change. Prediction of Arctic sea ice concentration has been investigated by many disciplines and predictions have been made using a variety of methods.

Factors controlling the bifurcation structure of sea ice retreat [PDF]
, 2012 The contrast in surface albedo between sea ice and open ocean suggests the possibility of an unstable climate state flanked by two separate stable climate states. Previous studies using idealized single-column models and comprehensive climate models have
