How Ice Composition Controls Radiatively Driven Convection Under Lake Ice

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Light transmission through the ice cover of lakes can heat near‐surface waters and result in radiatively driven convection (RDC), a prominent source of under‐ice water motion in spring. We investigate the impact of ice composition on the under‐ice water column using fully resolved two‐dimensional numerical simulations of the water that account

The Evolving Paleobathymetry of the Circum‐Antarctic Southern Ocean Since 34 Ma: A Key to Understanding Past Cryosphere‐Ocean Developments

Geochemistry Geophysics Geosystems, 2020
The Southern Ocean is a key player in the climate, ocean, and atmospheric system. As the only direct connection between all three major oceans since the opening of the Southern Ocean gateways, the development of the Southern Ocean and its relationship ...

Divergent Impacts of Precipitation Regimes on Autumn Phenology in the Northern Hemisphere Mid‐ to High‐Latitudes

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Climate change has altered precipitation regimes and shifted the end of the vegetation growing season (end of the season [EOS]), with consequences for terrestrial carbon and water cycles. However, the impacts of precipitation regimes, that is, total precipitation (Ptotal) and precipitation frequency (Pfreq), on EOS remain unclear.

Emergent Constraint on CMIP6 Model Projections of Winter Ice‐Free Periods in the Barents–Kara Sea

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Severe winter ice loss in the Barents–Kara Sea (BKS) affects the local environment and climate in other regions. To reduce sea ice projection uncertainties and reliably identify future ice‐free periods, we apply a time‐varying emergent constraint method to model simulations from the Coupled Model Intercomparison Project Phase 6 (CMIP6).

Remote Sensing of Snow Cover Using Spaceborne SAR: A Review

Remote Sensing, 2019
The importance of snow cover extent (SCE) has been proven to strongly link with various natural phenomenon and human activities; consequently, monitoring snow cover is one the most critical topics in studying and understanding the cryosphere.

Pacific‐to‐Arctic Oceanic Nitrate Fluxes: First Bering Strait Overwinter Nitrate Time‐Series (2022–2023) Show Winter Replenishment and Suggest Decadal Flux Increase

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The first overwinter (September 2022–July 2023) biogeochemical (nitrate, dissolved oxygen, fluorescence, and turbidity) mooring time‐series from the Bering Strait indicate late summer secondary productivity/ammonification, very minor oxygen consumption in winter, and a spring bloom triggered by sea‐ice retreat.

Runaway Cooling From Large Solar Reductions Modulated by Ocean Overturning Circulation and Heat Uptake

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The climate system can respond asymmetrically to warming and cooling, yet this asymmetry remains underexplored. This study uses multi‐century experiments with two coupled global climate models under idealized abrupt solar forcing changes of ± $\pm $1%, 2%, 4%, and 6%.

Have Impacts of Intense Arctic Cyclones on Summer Sea Ice Reached a Maximum?

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Observations show that Arctic cyclones can significantly affect the marginal ice zone (MIZ). Understanding how these effects may evolve in the future is critical for accurately predicting future ice loss, yet cyclone‐sea ice interactions in global climate models are understudied.
