Research on the Response Characteristics and Identification of Infrasound Signals in the Jialongcuo Ice Avalanche, Tibet

open access: yesRemote Sensing, 2023
Due to the inability of remote sensing satellites to monitor avalanches in real time, this study focuses on the glaciers in the rear edge of Jialongcuo, Tibet, and uses infrasound sensors to conduct real-time monitoring of ice avalanches.

Comparison of ice/water classification in Fram Strait from C- and L-band SAR imagery

open access: yesAnnals of Glaciology, 2018
In this paper an algorithm for ice/water classification of C- and L-band dual polarization synthetic aperture radar data is presented. A comparison of the two different frequencies is made in order to investigate the potential to improve classification ...

Timing of the Baltic Ice Lake in the eastern Baltic [PDF]

open access: yesBulletin of the Geological Society of Finland, 2013
A shoreline database for the Baltic, covering the Late Weichselian and Holocene, was compiled. The database includes about 1600 sites from Estonia, Latvia, Lithuania, Fin- land, NW Russia, Poland, Sweden and was used to create a GIS-based ...

On the deglaciation chronology of the Palivere ice-marginal zone, northern Estonia [PDF]

open access: yesBulletin of the Geological Society of Finland, 2012
This paper presents new bio-, litho- and chronostratigraphical evidence from two adjacent sediment sequences of the Tõdva and Saku basins, northern Estonia that refine the age estimate of the Palivere ice-marginal zone and the deglaciation history of ...

The development of a late Weichselian - early Holocene subaqueous ice-contact fan, Teikangas, SW Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1996
The depositional environment of the Teikangas formation in southwestern Finland has been studied. The formation is an isolated, ice marginal accumulation of coarse-grained sediments north of the Hämeenkangas ridge, related to the Weichselian ice sheet ...

Little Ice Age glacial geomorphology and sedimentology of Portage Glacier, South-Central Alaska [PDF]

open access: yesFinisterra - Revista Portuguesa de Geografia, 2009
The study of glacial landforms and deposits is important, as it isdifficult to observe processes under modern glaciers and ice-sheets. Thus landscapes and sediments that are the product of present glaciation can give insight into processes that occurred ...

Structural glaciology of Isunguata Sermia, West Greenland

open access: yesJournal of Maps, 2018
We present a 1:42,000 scale map of Isunguata Sermia, a land-terminating outlet glacier draining the western-sector of the Greenland Ice Sheet. Structure-from-Motion software applied to ∼3,600 aerial images collected by a fixed-wing unmanned aerial ...

Wave climate in the Arctic 1992–2014: seasonality and trends [PDF]

open access: yesThe Cryosphere, 2016
Over the past decade, the diminishing Arctic sea ice has impacted the wave field, which depends on the ice-free ocean and wind. This study characterizes the wave climate in the Arctic spanning 1992–2014 from a merged altimeter data set and a wave ...
