Quantifying the influence of sea ice on ocean microseism using observations from the Bering Sea, Alaska [PDF]

open access: yes, 2011
Microseism is potentially affected by all processes that alter ocean wave heights. Because strong sea ice prevents large ocean waves from forming, sea ice can therefore significantly affect microseism amplitudes.

ASTER-Derived High-Resolution Ice Surface Temperature for the Arctic Coast

open access: yesRemote 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

The bimodality of the East Siberian fast ice extent: mechanisms and changes

open access: yesAnnals of Glaciology, 2023
Using operational sea-ice maps, we provide first insight into the seasonal evolution of fast ice in the East Siberian Sea for the period between 1999 and 2021.

Robust Mosaicking of Lightweight UAV Images Using Hybrid Image Transformation Modeling

open access: yesRemote 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 ...

Effects of Wave-Induced Sea Ice Break-Up and Mixing in a High-Resolution Coupled Ice-Ocean Model

open access: yesJournal 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.

Wave–sea-ice interactions in a brittle rheological framework [PDF]

open access: yesThe Cryosphere, 2021
As sea ice extent decreases in the Arctic, surface ocean waves have more time and space to develop and grow, exposing the marginal ice zone (MIZ) to more frequent and more energetic wave events.

Prediction of Arctic Sea Ice Concentration Using a Fully Data Driven Deep Neural Network

open access: yesRemote 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]

open access: yes, 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

Active subglacial lakes and channelized water flow beneath the Kamb Ice Stream [PDF]

open access: yesThe 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 ...

Geographic muting of changes in the Arctic sea ice cover [PDF]

open access: yes, 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.
