The Impact of Subglacial Drainage System Evolution and Glacier Lake Outburst on Arctic Fjord Macronutrient Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Global warming is amplified in the Arctic, accelerating glacier melt and freshwater runoff. At tidewater glaciers, runoff typically enters fjords at depth and generates buoyancy‐driven circulation that enhances glacier‐ocean exchanges of energy and matter, influencing macronutrient delivery and marine primary production.

Warm Surface Waters Dominate Melting of the Denman‐Shackleton Ice Shelf System

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The ocean dynamics controlling the melting of the Denman‐Shackleton ice shelf system are investigated using a high‐resolution regional ocean‐sea ice‐ice shelf model. Our results show that basal meltwater production exhibits strong seasonal variability, driven by the ocean heat supply toward the ice shelf system, and occurs through two distinct

Thermal flexure and glacier calving

, 2019
Glaciers and ice sheets that terminate in bodies of water are expected to undergo thermal expansion as ice comes into contact with much warmer liquid water. Here, I investigate the roll that this thermal expansion plays in the fracturing processes that give rise to glacier calving.

Calving front positions for 42 key glaciers of the Antarctic Peninsula Ice Sheet: a sub-seasonal record from 2013 to 2023 based on deep-learning application to Landsat multi-spectral imagery [PDF]

Earth System Science Data
Calving front positions of marine-terminating glaciers are an essential parameter for understanding dynamic glacier changes and constraining ice modelling.

A dramatic 800-m retreat of a lake-terminating glacier on the Tibetan Plateau during 2014–2015, caused by glacier calving

Journal of Glaciology
Compared to land-terminating glaciers, lake-terminating glaciers generally experience a higher mass loss due to the feedback from processes such as calving, dynamic thinning and flow acceleration associated with proglacial lakes.

Surface dynamics and history of the calving cycle of Astrolabe Glacier (Adélie Coast, Antarctica) derived from satellite imagery [PDF]

The Cryosphere
The recent calving of Astrolabe Glacier on the Adélie Coast (East Antarctica) in November 2021 presents an opportunity to better understand the processes leading to ice tongue fracturing.

Responses of a polar predator to a glacier calving event [PDF]

Royal Society Open Science
Extreme episodic changes in Antarctic continental shelf regions, such as glacier calving or iceberg grounding, can fundamentally reshape regional sea-ice conditions.

Grounding Zone of Helheim Glacier, Greenland, From Terrestrial Radar Interferometry

Geophysical Research Letters
Helheim Glacier, in East Greenland, is a major outlet glacier that discharges about 33 Gigatons of ice per year into the ocean. Helheim has been undergoing a retreat since 2003.

Calving as a Source of Acute and Persistent Kinetic Energy to Enhance Submarine Melting of Tidewater Glaciers

Geophysical Research Letters
Calving icebergs at tidewater glaciers release large amounts of potential energy. This energy—in principle—could be a source for submarine melting, which scales with near‐terminus water temperature and velocity.
