Turbulence in the stratified boundary layer under ice: observations from Lake Baikal and a new similarity model [PDF]

Hydrology and Earth System Sciences, 2020
Seasonal ice cover on lakes and polar seas creates seasonally developing boundary layer at the ice base with specific features: fixed temperature at the solid boundary and stable density stratification beneath.

A geographically weighted machine learning framework with ICESat‑2 for estimating water storage of ice‑marginal lakes in eastern and northeastern Greenland

Journal of Hydrology: Regional Studies
Study region: Ice-marginal lakes (Trefork Lake，Romer Lake，Furesø, IML4) in eastern and northeastern GrIS (Greenland). Study focus: This study develops a novel water-depth inversion framework by integrating Sentinel-2, ArcticDEM, and ICESat-2 data within ...

Can Mineral Oil Slicks Be Distinguished From Newly Formed Sea Ice Using Synthetic Aperture Radar?

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
In this feasibility study discriminating oil slicks and newly formed sea ice using synthetic aperture radar (SAR) imagery is investigated, using imagery from the L-band high-resolution uninhabited aerial vehicle synthetic aperture radar (UAVSAR) airborne

Targeted Multifunctional Fluorine-Rich Copolymer Coating Design for Ambient-Stable Prelithiated SiOC Anodes. [PDF]

Adv Sci (Weinh)
A fluorine‐rich acrylate copolymer, poly (tridecafluorooctyl methacrylate‐co‐methyl methacrylate) (PFMMA), is introduced as a multifunctional protective coating to stabilize the prelithiated SiOC electrodes in humid conditions and preserve unimpeded interfacial ion/charge transport during redox reactions.

Numerical study of sea ice dynamics and wave-ice interactions in the marginal ice zone

, 2021
The Marginal Ice Zone (MIZ) is a highly dynamic region between the open ocean and the inner ice pack. The ice over this region is subjected to waves, introducing new forces but also changing the ice from a cohesive material to a mobile collection of ...

Oriented ice eddy detection network based on the Sentinel-1 dual-polarization data

Frontiers in Marine Science
The complex convergence of cold and warm ocean currents in the Nordic Seas provides suitable conditions for the formation and development of eddies. In the Marginal Ice Zones (MIZs), ice eddies contribute to the accelerated melting of surface sea ice by ...

Super-Resolution-Aided Sea Ice Concentration Estimation From AMSR2 Images by Encoder–Decoder Networks With Atrous Convolution

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Passive microwave data is an important data source for the continuous monitoring of Arctic-wide sea ice concentration (SIC). However, its coarse spatial resolution leads to blurring effects at the ice-water divides, resulting in the great challenges of ...

Ice-marginal proglacial lakes across Greenland: present status and a possible future

, 2022
Ice-marginal lakes can affect glacier dynamics but are ignored in studies of the evolution of the Greenland ice sheet (GrIS) and of peripheral mountain glaciers and ice caps (PGICs).

Surface roughness signatures of summer arctic snow-covered sea ice in X-band dual-polarimetric SAR

GIScience & Remote Sensing, 2020
Surface roughness of sea ice is primary information for understanding sea ice dynamics and air–ice–ocean interactions. Synthetic aperture radar (SAR) is a powerful tool for investigating sea ice surface roughness owing to the high sensitivity of its ...
