Influence of Atmospheric Rivers on Lake Ice Phenology in the Northern Hemisphere
Abstract Atmospheric rivers (ARs) can rapidly alter regional hydrothermal conditions and directly affect lake ice. This study presents the first assessment of AR impacts on lake ice phenology across the Northern Hemisphere. AR events were associated with positive anomalies in temperature, rainfall, and snowfall, as well as negative anomalies in solar ...

The Northern Eurasia Earth Science Partnership: An Example of Science Applied to Societal Needs [PDF]
Northern Eurasia, the largest landmass in the northern extratropics, accounts for ~20% of the global land area. However, little is known about how the biogeochemical cycles, energy and water cycles, and human activities specific to this carbon-rich, cold

Abstract Barite serves as a key proxy for reconstructing paleo‐oceanic productivity and chemistry in modern and ancient marine sediments. Although contemporary barite precipitation involves biological mediation, the mechanisms responsible for ancient barite formation remain unclear.

Weather Regime Diversity, Transitions, and Trends Using Hexagonal Self‐Organizing Maps
Abstract Persistent atmospheric circulation patterns, or weather regimes, strongly modulate surface weather and extremes, yet their internal diversity, transitions, and trends remain less understood for North America. We apply a self‐organizing map (SOM) framework to represent North American weather regimes using daily 500‐hPa geopotential height ...

Quantifying Under‐Ice Phytoplankton Blooms in the Changing Arctic and Southern Oceans
Abstract Historically, polar marine phytoplankton were thought to primarily grow after the seasonal breakup of sea ice, when there is plentiful light available in the surface ocean. However, observations of substantial productivity under sea ice has called this assumption into question.

An Initial Estimate of the Cost of Lost Climate Regulation Services Due to Changes in the Arctic Cryosphere [PDF]
Outlines how arctic sea ice and snow cover help maintain the global climate and ecosystems, the impact of changes in sea and land reflectivity and methane emissions, research on the social cost of carbon, and the estimated economic cost of climate ...

Calibrating an ice sheet model using high-dimensional binary spatial data
Rapid retreat of ice in the Amundsen Sea sector of West Antarctica may cause drastic sea level rise, posing significant risks to populations in low-lying coastal regions.

The Emergence of a Human Fingerprint in the Boreal Winter Extratropical Zonal Mean Circulation
Abstract The large‐scale atmospheric circulation plays an important role in regional climate. Recent studies have shown that poleward shifts in the Northern Hemisphere jet streams may be emerging, but the statistical significance and robustness are questionable.

Observed Drivers of Rapid Sea‐Ice Melt Events in the Arctic During Summer
Abstract Rapid, episodic sea‐ice loss during the summer is commonly attributed to strong winds from Arctic storms, but the physical relationship between winds and ice melt remains poorly understood. Therefore, we use observations of the air‐sea‐ice interface from autonomous buoys deployed throughout the Arctic over the last two decades to examine the ...

Abstract Bedload transport of sediment mixtures is fundamental to river morphology and impacts aquatic ecology. Adding fine grains enhances coarse‐grain transport, yet controlling mechanisms remain elusive. Employing discrete element simulations, we examine how fine‐grain size and proportion influence coarse‐grain flux.
