Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.

Bayesian Estimates of Ice Optical Properties for Lake Ice Modeling

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Ice and snow cover on frozen lakes is a natural barrier to solar radiation, reducing the transfer of energy that controls under‐ice thermal dynamics and biological productivity. Direct measurements of under‐ice irradiance remain scarce due to logistical constraints.

Bacteria as Passive Passengers in the Equatorial Pacific Biological Carbon Pump

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bacteria are important agents modulating the efficiency of the ocean's biological carbon pump (BCP). The long‐standing view considers bacteria as degraders of sinking particulate organic carbon (POC), yet underappreciates their contribution to carbon export.

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.

How Volume Increases the Mobility of Geophysical Granular Flow: A Unified Rheological Perspective

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Geophysical granular flows, involving rapidly flowing granular materials, can exhibit volume‐enhanced mobility. Lacking a mechanistic understanding of such size effects limits the applications of lab‐scale findings to natural events. Using discrete element method simulations, we find that increasing granular system size suppresses energy ...

Bromine Enrichment Signal in Svalbard Shallow Cores Reflects Changes of Seasonal Sea Ice Variability

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bromine enrichment Brenr $\left(\mathrm{B}{\mathrm{r}}_{\mathrm{e}\mathrm{n}\mathrm{r}}\right)$ has been widely used as a proxy for past sea ice reconstructions. In this study, three firn cores drilled on Holtedahlfonna (Svalbard) were analyzed for trace elements. Excluding a single year data, a positive correlation was observed between Brenr $

The Slip Distributions of the 1952 and 2025 Kamchatka Earthquakes From Tsunami Waveforms Recorded Around the Pacific Ocean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The July 2025 Kamchatka earthquake (Mw 8.8) generated Pacific‐wide tsunamis. Inversion of 40 DART bottom pressure records revealed a large (∼9 m) slip at 200–400 km southwest of the epicenter. This model reproduces the local geodetic data, and is similar to other finite fault models based on teleseismic and geodetic data. Inversion of the tide

Light Transmission Through Arctic Sea Ice - Large-Scale Studies on Seasonality and Spatial Variability [PDF]

, 2013
Arctic sea ice has declined and become thinner and more seasonal during the last decade. One consequence of this is that the surface energy budget of the Arctic Ocean is changing.

Global Diurnal Variation Characteristics of Aerosol Optical Depth From 32 Years of AERONET Observations

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aerosols are ubiquitous microscopic particles in the atmosphere, and their diurnal variation characteristics reflect short‐term atmospheric changes that are crucial for climate monitoring and prediction. However, satellite, ground‐based, and reanalysis systems cannot simultaneously provide observational authenticity together with full temporal–
