Historical occurrence of Antarctic icebergs within mercantile shipping routes and the exceptional events of the 1890s

open access: yesJournal of Glaciology, 2023
A major consideration for maritime activity in the Southern Hemisphere is the northern limit of icebergs, or the Southern Ocean Limit Of Known Ice (SOLOKI).

A Law for Small Scale, Continuous Calving [PDF]

open access: yes, 2014
Ice shelves are formed by the viscous flow of inland ice into the ocean, they are floating and loosing mass by iceberg calving. There are two different kinds of calving: large tabular icebergs detach as singular events in time, and small scale calving ...

Calving giant icebergs: old principles, new applications

open access: yesAntarctic Science, 2006
Earth-orbiting satellites can now monitor calving of large icebergs from ice shelves bordering the marine West Antarctic Ice Sheet, and recent calving events have stimulated interest in calving mechanisms. To advance this interest pioneering work in brittle and ductile fracture mechanics is reviewed, leading to a new application to calving of giant ...

Response of Marine‐Terminating Glaciers to Forcing: Time Scales, Sensitivities, Instabilities, and Stochastic Dynamics [PDF]

open access: yes, 2018
Recent observations indicate that many marine‐terminating glaciers in Greenland and Antarctica are currently retreating and thinning, potentially due to long‐term trends in climate forcing.

Freshwater flux from ice sheet melting and iceberg calving in the Southern Ocean [PDF]

open access: yes, 2016
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.

Iceberg properties and distributions in three Greenlandic fjords using satellite imagery

open access: yesAnnals of Glaciology, 2017
Icebergs calved from tidewater glaciers represent about one third to one half of the freshwater flux from the Greenland ice sheet to the surrounding ocean. Using multiple satellite datasets, we quantify the first fjord-wide distributions of iceberg sizes

Efficient Location and Extraction of the Iceberg Calved Areas of the Antarctic Ice Shelves

open access: yesRemote Sensing, 2020
Continuous, rapid, and precise monitoring of calving events contributes to an in-depth understanding of calving mechanisms, which have the potential to cause significant mass loss from the Antarctic ice sheet.

Effect of topography on subglacial discharge and submarine melting during tidewater glacier retreat. [PDF]

open access: yes, 2017
-We explored secular variations in subglacial discharge and submarine melting with an idealized model -Subglacial discharge increases as tidewater glaciers retreat along retrograde beds -Submarine melting depends on subglacial discharge and ...

Iceberg calving from the Amery Ice Shelf, East Antarctica [PDF]

open access: yesAnnals of Glaciology, 2002
AbstractWe investigate the iceberg-calving cycle of the Amery Ice Shelf (AIS), East Antarctica, using evidence acquired between 1936 and 2000. The most recent major iceberg-calving event occurred between late 1963 and early 1964, when a large berg totalling about 10 000 km2 in area broke from the ice front.

Sensitivity of a calving glacier to ice–ocean interactions under climate change: new insights from a 3-D full-Stokes model [PDF]

open access: yesThe Cryosphere, 2019
Iceberg calving accounts for between 30 % and 60 % of net mass loss from the Greenland Ice Sheet, which has intensified and is now the single largest contributor to global sea level rise in the cryosphere.
