Velocity response of Petermann Glacier, northwest Greenland, to past and future calving events [PDF]
, 2018 Dynamic ice discharge from outlet glaciers across the Greenland Ice Sheet has increased since the beginning of the 21st century. Calving from floating ice tongues that buttress these outlets can accelerate ice flow and discharge of grounded ice. However,

Brief communication: Rapid acceleration of the Brunt Ice Shelf after calving of iceberg A-81 [PDF]
The CryosphereThe Brunt Ice Shelf, Antarctica, accelerated rapidly from a velocity of 900 to 1500 m a−1 during 6 months, following calving of a 1500 km2 iceberg on 22 January 2023.

The Holocene retreat dynamics and stability of Petermann Glacier in northwest Greenland [PDF]
, 2018 Submarine glacial landforms in fjords are imprints of the dynamic behaviour of marine-terminating glaciers and are informative about their most recent retreat phase.

Glaciological and marine biological studies at perimeter of Dronning Maud Land, Antarctica [PDF]
The author has identified the following significant results. A nearly complete map of the Dronning Land coastline from 10 deg W to 29 deg E was produced. Based on this, it was determined that for the past 20 years, the minimum calving rate from this part

Geographical distribution and volume of Antarctic icebergs derived from ship observation data
Annals of Glaciology, 2017 Information on the occurrence, spatial distribution and morphometric characteristics of Antarctic icebergs is needed in a large number of applications including navigation, heat and freshwater balance calculations, biochemistry of the ocean and ...

A viscoelastic phase-field model for iceberg calving
Iceberg calving accounts for around half of the ice lost annually from Antarctica, but realistic representation of fracture and calving in large-scale ice sheet models remains a major unsolved problem in glaciology. We present a new phase-field viscoelastic model for fracture that simulates the slow deformation of ice and the distribution and evolution

Sea-level response to ice sheet evolution: An ocean perspective [PDF]
The ocean's influence upon and response to Antarctic ice sheet changes is considered in relation to sea level rise over recent and future decades. Assuming present day ice fronts are in approximate equilibrium, a preliminary budget for the ice sheet is ...

Ecological consequences of a massive iceberg calving in Antarctica
, 2023 Dans le cadre de la théorie d'évolution des traits d'histoire de vie, l'allocation de l'énergie aux différentes fonctions des organismes au cours des différentes activités clés de leur cycle annuel revêt un caractère essentiel. Ainsi, la stratégie énergétique d'un animal longévif doit lui permettre de faire face aux contraintes extrêmes imposées par l ...

Impact of varying solar angles on Arctic iceberg area retrieval from Sentinel-2 near-infrared data
Annals of GlaciologyIcebergs are part of the glacial mass balance and they interact with the ocean and with sea ice. Optical satellite remote sensing is often used to retrieve the above-waterline area of icebergs.
