Waves of Accelerated Motion in a Glacier Approaching Surge: the Mini-Surges of Variegated Glacier, Alaska, U.S.A.

open access: yes, 1987
Periods of dramatically accelerated motion, in which the flow velocity increases suddenly from about 55 cm/d to a peak of 100–300cm/d and then decreases gradually over the course of a day, occurred repeatedly during June and July 1978–81 in Variegated ...

Bridging Geomythology and Geospatial Analysis for Flood Risk Assessment in Tamil Nadu

open access: yesJournal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT The need for more holistic and context‐aware approaches to flood‐risk assessment has become increasingly urgent with extreme climate change events faced globally. Modern models overlook the long‐term environmental knowledge incorporated in ancient literature, myths, and cultural memory as they rely primarily on hydrological and geospatial ...

Projected Changes in Extreme Sea Level and Sea‐Level Distribution in the China Marginal Seas Using Dynamical Downscaling

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Future global and regional mean sea level (MSL) changes have been widely quantified, yet projections of extreme sea level (ESL) remain limited, despite their substantial environmental and socioeconomic risks to densely populated coastal regions such as the marginal seas near China. Here, we use a high‐resolution (∼8 km) regional ocean model to

A Comprehensive Examination of the Medvezhiy Glacier’s Surges in West Pamir (1968–2023)

open access: yesRemote Sensing
The Vanj River Basin contains a dynamic glacier, the Medvezhiy glacier, which occasionally poses a danger to local residents due to its surging, flooding, and frequent blockages of the Abdukahor River, leading to intense glacial lake outburst floods ...

Microphysics and Kinematics of a High Flash Rate Storm With a Bottom‐Heavy Charge Structure

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract An atypical thunderstorm with unusual lightning and charge structure characteristics propagated through Cordoba province, Argentina, during the austral warm season in late 2018. This storm exhibited echo tops near 10.5 km, with high lightning activity concentrated at low altitudes.

A century of flow and surge history of Sít’ Tlein (Malaspina Glacier), Southeast Alaska

open access: yesJournal of Glaciology
Sít’ Tlein (Malaspina Glacier), located in Southeast Alaska, has a complex flow history. This piedmont glacier, the largest in the world, is fed by three main tributaries that all exhibit similar flow patterns, yet with varying surge cycles. The piedmont

Geometry and Dynamics of a Surge-type Glacier

open access: yes, 1977
Measurement of geometry, motion, and mass balance from Variegated Glacier, Alaska portray conditions in this surge-type glacier close to the mid-point of its 20 year surge cycle.

The long multiphase trunk–tributary surge history of the high-Arctic Chapman Glacier, 1959–2023

open access: yesArctic, Antarctic, and Alpine Research
Surge-type glaciers have been identified throughout the Canadian Arctic, but detailed surge behavior has been sparsely studied. Recent high spatiotemporal resolution satellite products enable such studies, allowing for better process-based understanding ...

Seismic Clues to Surging Glaciers

open access: yesEos, 2019
Measuring seismic waves passing through a glacier suggests that not only is liquid water playing a role in periodic surging but the water is channeled into cracks from across the ice.

Geomorphological and historical records of the surge-type behaviour of Hansbreen (Svalbard)

open access: yesAnnals of Glaciology
This paper presents geomorphological and historical records of the surge-type behaviour of Hansbreen, one of the most studied tidewater glaciers in Svalbard.
