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

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

Tracer Measurements in Growing Sea Ice Support Convective Gravity Drainage Parameterizations [PDF]
, 2020 Gravity drainage is the dominant process redistributing solutes in growing sea ice. Modeling gravity drainage is therefore necessary to predict physical and biogeochemical variables in sea ice.

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

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 ...

Deep learning of systematic sea ice model errors from data assimilation increments [PDF]
, 2023 Data assimilation is often viewed as a framework for correcting short-term error growth in dynamical climate model forecasts. When viewed on the time scales of climate however, these short-term corrections, or analysis increments, can closely mirror the systematic bias patterns of the dynamical model. In this study, we use convolutional neural networks

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 ...

Sea ice transports in the Weddell Sea [PDF]
Journal of Geophysical Research: Oceans, 2001 Time series of sea ice draft in the Weddell Sea are evaluated together with hydrographic observations, satellite passive microwave data, and ice drift for estimation of the freshwater fluxes into and out of the Weddell Sea. Ice draft is measured with moored upward looking sonars since 1990 along two transects across the Weddell Gyre.
