Dynamics of glacier calving at the ungrounded margin of Helheim Glacier, southeast Greenland. [PDF]

Journal of geophysical research. Earth surface, 2015
During summer 2013 we installed a network of 19 GPS nodes at the ungrounded margin of Helheim Glacier in southeast Greenland together with three cameras to study iceberg calving mechanisms. The network collected data at rates up to every 7 s and was designed to be robust to loss of nodes as the glacier calved.

Glacier dynamics

, 1977
A model is proposed for the study of general two-dimensional 'polythermal' glacial ice flows. It consists of equations of conservation of mass, momentum and energy together with a constitutive relation between stress and strain rate and a full set of boundary conditions. A novel aspect is the consideration of the moisture content of temperate ice as an

Recent structural evolution of Forni Glacier tongue (Ortles-Cevedale Group, Central Italian Alps)

Journal of Maps, 2017
Structural glaciology yields important details about the evolution of glacier dynamics in response to climate change. The maps provided here document the occurrence and evolution of brittle and ductile structures on the tongue of Forni Glacier, Ortles ...

Response of glacier flow and structure to proglacial lake development and climate at Fjallsjökull, south-east Iceland

Journal of Glaciology, 2019
Over recent decades, the number of outlet glaciers terminating in lakes in Iceland has increased in line with climate warming. The mass-balance changes of these lake-terminating outlet glaciers are sensitive to rising air temperatures, due to altered ...

Signal: SAR for ice, glacier and global dynamics [PDF]

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
SIGNAL is an innovative earth exploration mission proposal with the main objective to estimate accurately and repeatedly topography and topographic changes associated with mass change or other dynamic effects on glaciers, ice caps and polar ice sheets.

Long-term records of glacier surface velocities in the Ötztal Alps (Austria) [PDF]

Earth System Science Data, 2019
Climatic forcing affects glacier mass balance, which causes changes in ice flow dynamics and glacier length changes on different timescales. Mass balance and length changes are operationally used for glacier monitoring, whereas only a few time series of ...

Understanding Complex Debris-Covered Glaciers: Concepts, Issues, and Research Directions

Frontiers in Earth Science, 2021
Understanding the climate-glacier dynamics of debris-covered glaciers is notoriously difficult given a multitude of controlling factors and feedback mechanisms involving climate forcing, debris-load properties, supraglacial water bodies, and multi-scale ...

Spatiotemporal variation of glacier dynamics and its relationship with changes in high mountain ecosystems in the Cordillera Blanca, Peru

Revista de Teledetección
In high mountain ecosystems, glaciers, lakes and wetlands play an important role in local water resources, where a variation in glacier dynamics can affect the rest of the ecosystem components due to their hydrological connections.

Contrasts in the response of adjacent fjords and glaciers to ice-sheet surface melt in West Greenland

Annals of Glaciology, 2016
Neighboring tidewater glaciers often exhibit asynchronous dynamic behavior, despite relatively uniform regional atmospheric and oceanic forcings. This variability may be controlled by a combination of local factors, including glacier and fjord geometry ...

Marine outlet glacier dynamics, steady states and steady-state stability

Journal of Glaciology, 2022
Laterally confined marine outlet glaciers exhibit a diverse range of behaviours. This study investigates time-evolving and steady configurations of such glaciers.
