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