Brief Communication "The 2013 Erebus Glacier Tongue calving event" [PDF]
The Erebus Glacier Tongue, a small floating glacier in southern McMurdo Sound, is one of the best-studied ice tongues in Antarctica. Despite this, its calving on the 27 February 2013 (UTC) was around 10 yr earlier than previously predicted.

Fracture and Calving Front Evolution: A Case Study of Fimbul Ice Shelf, Antarctica
ABSTRACT This study combines historical records, satellite remote sensing data, and inverse modelling to investigate crack formation and calving front evolution of the Fimbul Ice Shelf, Antarctica. Historical maps from the 1950s, together with satellite imagery from 1970s–2026, are used to reconstruct calving‐front positions and track the evolution of ...

Antarctic iceberg melt rate variability and sensitivity to ocean thermal forcing
Changes in iceberg calving fluxes and oceanographic conditions around Antarctica have likely influenced the spatial and temporal distribution of iceberg fresh water fluxes to the surrounding ocean basins.

Hidden subsurface suspended sediment export from Greenland's marine‐terminating glaciers
Abstract Runoff and calved ice volumes from the Greenland Ice Sheet are well constrained, but quantifying the associated suspended sediment flux remains challenging. Here we present near‐terminus observations from three glacierized fjords in southeast Greenland, combining full‐depth turbidity profiles and current velocity from summer 2024 to evaluate ...

Icebergs, jigsaw puzzles, and genealogy: automated multi-generational iceberg tracking and lineage reconstruction [PDF]
Tabular icebergs calve from ice shelves and glaciers in Antarctica, Greenland, and northern Ellesmere Island. These “ice islands”, as they are referred to in the Arctic, drift, melt, and fragment, contributing freshwater and nutrients to the ocean ...

Abstract Nitrogen uptake by phytoplankton influences Southern Ocean productivity and carbon export, but how source‐resolved meltwater is associated with nitrate and ammonium use remains unclear. Here, 15N tracer incubations and a δ18O‐salinity mixing model were combined to examine nitrogen uptake in the early‐summer Cosmonaut Sea.

Freshwater flux from ice sheet melting and iceberg calving in the Southern Ocean [PDF]
This dataset is a multiyear mean Southern Ocean freshwater flux field that uses recently compiled measurements of ice sheet melting, iceberg calving, iceberg tracking, and river runoff.

Seafloor mapping in a high Arctic fjord (Grise Fiord) revealed many submarine landslides triggered by iceberg groundings, coastal debris flows and delta collapses. The dating of three of them suggests that they occurred at past climate transitions. ABSTRACT Arctic fjords are experiencing rapid environmental change driven by amplified high‐latitude ...

Quantifying user variability in the traditional X‐ray ice‐rafted‐debris counting technique
ABSTRACT The flux of icebergs is most commonly constrained in the palaeo‐record by manually counting gravel clasts in sediment core X‐ray images—a trusted method in Quaternary science and palaeoceanography for nearly 40 years. In this study, we explore the reproducibility (user consistency and between‐user variability) of the traditional clast‐counting

Greenland iceberg melt variability from high-resolution satellite observations [PDF]
Iceberg discharge from the Greenland Ice Sheet accounts for up to half of the freshwater flux to surrounding fjords and ocean basins, yet the spatial distribution of iceberg meltwater fluxes is poorly understood.
