Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, Volume 41, Issue 8, Page 1404-1416, November 2026.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

A SWOT‐Based Framework for Gauge‐Independent River Discharge Estimation

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract The declined accessibility of in situ water records has limited our ability to monitor river dynamics and manage freshwater resources. Satellite altimetry provides an important alternative, but traditional radar altimeters can only observe rivers at nadir points where the ground track crosses the channel, offering sparse spatial coverage.

Linking Deep Carbon to Surface Emission in the Carpathian–Pannonian Region: Isotope Systematics of Fluid Inclusions and Groundwater

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract CO2 degassing from the deep Earth provides important insights into the global carbon cycle. CO2‐rich fluid inclusions in mantle xenoliths record fluid sources and migrations in the deep lithosphere, while the contribution of mantle components in groundwater can be traced via dissolved gas geochemistry.

Dynamics of a High‐Pressure Ice Layer Between Two Oceans

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Mass and heat transfer efficiency through a high‐pressure (HP) ice layer located between a surface, or subsurface, ocean and the core is a key topic for determining the potential habitability of large ocean worlds. The possible existence of a dense salty ocean between the HP ice layer and the rocky core calls for a study of its implications ...

Isoanemeity Predicts the Effect of Leaf Versus Stem Flexure on Plant Drag

Geophysical Research Letters
Flexible vegetation is deflected by fluid flow, reducing drag forces and thus inducing complex feedbacks which affect scalar transport, sediment mobility and biogeochemical cycling. However, we presently lack mathematical models for this disturbance, for

The Climatological ITCZ Location Modulates Extratropics‐to‐Tropics Teleconnections

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract While extratropical forcing has far‐reaching effects through teleconnections, the Intertropical Convergence Zone (ITCZ) has been shown to partly block the propagation of extratropical perturbations to the opposite hemisphere. However, the influence of the ITCZ location on the tropical response and the blocking effect remain poorly understood ...

Hydrosphere [PDF]

, 2005
The hydrosphere [Greek hydor water and sphera sphere] refers to the water on or surrounding the surface of the globe, as distinguished from those of the lithosphere (the solid upper crust of the earth) and the atmosphere (the air surrounding the earth).

Resolution Dependence of the Climate Feedback Parameter in Km‐Scale Climate Models

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Global storm‐resolving models (GSRMs) provide new opportunities to investigate the climate response to warming with explicitly resolved deep convection. However, the limited number of existing studies has so far precluded the systematic assessment of similarities and differences across GSRMs.

More Frequent Atmospheric Rivers and Associated Precipitation Extremes Induced by the Baroclinic Annular Mode

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Atmospheric rivers (ARs) play a crucial role in the global hydrological cycle, yet how the intrinsic midlatitude atmospheric variability modulates their activity on subseasonal timescales remains poorly understood. Here, we show that AR frequency and landfall in both hemispheres vary strongly with the strength and phase of the Baroclinic ...

A Radio Science Experiment for Dragonfly to Investigate Titan's Rotation and Interior Structure

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract NASA's mission Dragonfly to Titan is scheduled for launch in 2028 with arrival in 2034 to study Titan's prebiotic chemistry and habitability. We propose a radio science experiment for Dragonfly, in which radiometric tracking of the rotorcraft from the Deep Space Network, already baselined for communications and navigation, is used as a ...
