State of balance of the cryosphere [PDF]
Reviews of Geophysics, 1991 The current state of balance of the terrestrial ice sheets and glaciers is poorly known. What little data are available suggest that, worldwide, mountain glaciers have receded since about the mid‐nineteenth century, with occasional interruptions of the retreat. The interior part of the Greenland ice sheet appears to be thickening or in near equilibrium,

Rivers Influence Reef Pass Formation in the Society Islands
Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Reef passes are deep, navigable channels dissecting coral reefs around volcanic islands. Many reef passes are located offshore of large island river basins, suggesting a potential causal relationship. To clarify the mechanisms that form and maintain reef passes, we quantify the relationships between reef pass location and drainage basin size ...

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Over the period 2021–2024, glaciers in Western Canada and the conterminous US (WCAN‐US), and Switzerland respectively lost mass at rates of 22.2 ± 9.0 and 1.5 ± 0.3 Gt yr−1 representing a twofold increase in mass loss compared to the period 2010–2020.

Assessment of surface albedo effect on the position of zero isotherm
Лëд и снег, 2015 Calculations with one-layer radiative model of the atmosphere based upon the data of Surface Radiation Budget archive over 1984–2007 allowed to assess changes in temperature distribution over the earth’s surface associated with radiation factors in ...

Cryomorphological topographies in the study of ice caves [PDF]
, 2018 Producción CientíficaThe current interest in ice caves requires that their varied manifestations be known as accurately as possible in view of their responses to a global change and also to their great potential as paleoenvironmental witnesses.

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Rock weathering impacts global nutrient cycles but factoring intrinsic properties of bedrock into weathering models remains a challenge. Here we show that two common tracers of silicate weathering—uranium (U) activity ratios and lithium (Li) isotope ratios of river solutes—inform lithology‐specific modes of landscape denudation.

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract As a critical component of global water cycle, diurnal variation of precipitation (DVP) exhibits significant spatial heterogeneity under topographic effect. However, DVP's dependency on elevation and evolution in a warming climate remain unclear.

Northern Eurasia Future Initiative (NEFI): facing the challenges and pathways of global change in the twenty-first century [PDF]
, 2017 During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental ...

Alkalinity (Bicarbonate) Pumping by Coastal Macroalgal Forests
Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Macroalgal ecosystems remain underrepresented in blue carbon frameworks, largely due to uncertainties surrounding the fate of macroalgal carbon during decomposition. Laboratory experiments on Sargassum horneri, Codium fragile, and Ulva australis revealed concurrent increases in total alkalinity and dissolved inorganic carbon, indicating ...

Variable Silicon Isotope Fractionation Between Authigenic Phases and Pore Fluids in Marine Sediments
Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Formation and subsequent burial of authigenic phases have been recognized as a key process removing silicon from the ocean. However, the effect of authigenic phase formation on the isotopic mass balance of silicon in the ocean is not clear. Here, we constrain the apparent silicon isotope (δ30Si) fractionation associated with early diagenesis ...
