Abstract Climatic surface mass balance (SMB) meltwater runoff models are used to estimate current and future Greenland Ice Sheet sea level contributions. However, comparisons between SMB model runoff and in situ proglacial river discharge observations show large discrepancies.

Compositional change of meltwater infiltrating frozen ground [PDF]
Meltwater reaching the base of the snowpack may either infiltrate the underlying stratum, run off, or refreeze, forming a basal ice layer. Frozen ground underneath a melting snowpack constrains infiltration promoting runoff and refreezing.

Landscape Controls River Continuum Dissolved Organic Carbon in Northeastern Alaska
Abstract Rivers draining continuous permafrost landscapes on the North Slope of Alaska span from the mountains to the coast, integrating gradients in vegetation, soil organic matter, and hydrologic flow. We investigated how these landscape transitions influence dissolved organic carbon (DOC) concentrations, radiocarbon ages, and export along the river ...

Abstract Accurate estimation of snowpack dynamics is essential for predicting snowmelt‐driven hydrological processes in mountainous regions. Although data assimilation techniques can integrate remote sensing observations into snow models to reduce uncertainties, their operational implementation remains constrained by sparse and irregular coverage of ...

Abstract Climate models robustly project an El Niño–like warming under rising CO2, yet recent observations show the opposite with enhanced zonal SST gradients. Whether the long‐term projection is relevant for interpreting historical trends remains questionable.

Abstract Radiative transfer (RT) models typically solve the radiative transfer equation separately in either the atmosphere or the ocean, limiting accuracy across the atmosphere‐ocean interface. Here, we employ a coupled scalar discrete ordinate RT model to examine methods for the input of measured inherent optical properties (IOPs) of oceanic ...

Mapping Global GNSS Vertical Velocities to Solid Earth Figure Change
Abstract The Earth's figure evolves in response to glacial isostatic adjustment (GIA), surface‐mass redistribution, and rotational and mantle‐driven processes. While temporal changes in the geoid's flattening are monitored through low‐degree gravity field harmonics, the geometric response of the solid Earth can be assessed independently from GNSS ...

Abstract Increased freshwater discharge from Arctic glaciers modifies the carbonate chemistry of coastal fjords. We investigated the carbon isotopic composition (Δ14C and δ13C) of dissolved inorganic carbon (DIC) in Kongsfjorden, Svalbard, to evaluate how freshwater inputs and water‐mass exchange shape fjord carbon dynamics.
