Three-dimensional modelling of calving processes on Johnsons Glacier, Livingston Island, Antarctica. [PDF]
Iceberg calving is an important mass loss mechanism from ice shelves and tidewater glaciers for many mid and high-latitude glaciers and ice caps, yet the process is not well represented in prognostic models of ice dynamics.

A short-term series of quantitative observations of calving activity of Fuerza Aérea Glacier (Greenwich Island, the South Shetland Islands, Antarctica) was conducted in order to test new methods of monitoring calving.

Nonlinear Release of Subinertial Diurnal Internal Tides Forms Spiral Internal Solitary Waves
Abstract Earth's rotation imposes a dynamical barrier on the free propagation of internal tides at high latitudes, raising questions about the fate of tidal energy poleward of the critical latitude. Satellite observations reveal spiral internal solitary waves (ISWs) along the continental slope of the South Orkney Plateau.

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 ...

Detection of Glacier Calving Margins with Convolutional Neural Networks: A Case Study
The continuous and precise mapping of glacier calving fronts is essential for monitoring and understanding rapid glacier changes in Antarctica and Greenland, which have the potential for significant sea level rise within the current century.

Effects of undercutting and sliding on calving: a global approach applied to Kronebreen, Svalbard [PDF]
In this paper, we study the effects of basal friction, sub-aqueous undercutting and glacier geometry on the calving process by combining six different models in an offline-coupled workflow: a continuum–mechanical ice flow model (Elmer/Ice), a climatic

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

Including debris cover effects in a distributed model of glacier ablation [PDF]
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

A simple model of mélange buttressing for calving glaciers [PDF]
Abstract. Both ice sheets on Greenland and Antarctica are discharging ice into the ocean. In many regions along the coast of the ice sheets, the icebergs calf into a bay. If the addition of icebergs through calving is faster than their transport out of the embayment, the icebergs will be frozen into a mélange with surrounding sea ice in winter. In this

Ground-based time-lapse cameras are often used to monitor glacier recession, which is primarily driven by the falling of ice from the glacier front, known as iceberg calving or, more commonly, calving events.
