Sorted circles and polygons are widespread features of periglacial landscapes, but the controls on their development remain poorly understood, impeding their use as palaeoenvironmental indicators. We investigate the relationship of sorted circles and polygons to altitude in the northern Billefjorden area, central Svalbard. The patterns occur in two distinct elevation zones, below 200–250 m asl and above 600 m asl. The higher‐elevated patterns have smaller diameters and shallower sorting depths due to a thinner active layer at higher elevations, suggesting that sorted patterns can indicate climate conditions and ground thermal state when the patterns initiated. Geology is believed to be of less importance for pattern morphology in the study area, causing only its fine‐scale variations. The pattern diameter‐to‐sorting depth ratios have a median value of 3.57, consistent with previous studies and theoretical models of patterned‐ground formation involving circulation mechanisms. Large‐scale sorted patterns may develop over centennial timescales in this high‐Arctic environment. They are probably not in equilibrium with present‐day climate conditions and have probably formed throughout the Holocene. Copyright © 2017 John Wiley & Sons, Ltd.

“…Nordenskiöldbreen has been the subject of a number of glaciological (Den Ouden et al, 2010;Hagen, Eiken, Kohler, & Melvold, 2005;Rachlewicz et al, 2007;Van Pelt et al, 2012, 2014 and geomorphological (Boulton, 1970(Boulton, , 1976Kłysz, 1988;Kłysz, Lindner, Marks, & Wysokiński, 1989;Slater, 1925;Stacke, Mida, Lehejček, Tóthová, & Nývlt, 2013;Strzelecki, 2011) studies, including some geomorphological mapping (Karczewski et al, 1990;Kłysz et al, 1989) (Baeten, Forwick, Vogt, & Vorren, 2010;Plassen, Vorren, & Forwick, 2004;Szczuciński, Zajączkowski, & Scholten, 2009). However, most of the previous work concentrated on the northern margin, and so far no coherent map of glacial geomorphology has been produced for both terrestrial parts of the foreland and hence no comparison has been made between the landform signatures of these two clearly contrasting parts of the snout.…”

Glacial geomorphology of the terrestrial margins of the tidewater glacier, Nordenskiöldbreen, Svalbard

A 1:4000 scale map of the terrestrial margins of the foreland of Nordenskiöldbreen depicts a polythermal glacial landsystem containing a record of the landform signatures of individual ice flow units that operate within the glacier snout. A 1:700 map provides a detailed overview of fluted terrain, based on unmanned aerial vehicle images captured in 2014. The pattern of landforms lying inside the Little Ice Age (LIA) latero-frontal moraine on the northern side of the fjord comprises a fluted till surface, which in turn grades into icemoulded bedrock. This signature records the recession of a single, wide ice flow unit, which was characterised by limited incorporation of subglacial material and restricted delivery of supraglacial debris. Inside the latero-frontal moraine on the south side of the fjord, a fluted surface is subordinate to a pronounced and large ice-cored moraine complex related to the confluence of five narrower ice flow units, each of which transported significant quantities of englacial and supraglacial debris at their suture zones as a series of longitudinal debris stripes. The suite of foreland landforms is diagnostic of both temperate subglacial and frozen-snout conditions, indicating the operation of a warm polythermal glacier fed by multiple flow units during the LIA.

“…Nordenskiöldbreen is a tidewater outlet polythermal type of glacier with an area of 242 km 2 , located in the northern part of the Billefjorden fjord (Hagen et al 1993). Further information on the study site and glacier retreat can be found in Plassen et al (2004), Rachlewicz et al (2007), van Pelt et al (2012), Stacke et al (2013), Vinšová et al (2015). The main emphasis was given to a land terminating part and a 250-m-long section of a proglacial river on the northwestern flank of the Nordenskiöldbreen snout.…”

Unmanned Aerial Vehicles (UAV) have technical capabilities to extended usage in various fields of science. The existing UAVs are to be relatively easily accessible in the near future. It is possible to equip them with different sensors but there are still some usage limitations. This paper focuses on demonstrating UAVs usage for research in polar regions. The research in polar regions is very specific and, due to harsh climate, limits the field work with UAVs. The options and limitations are presented in a case study performed in the Nordenskiöldbreen area, Svalbard Archipelago. In the end some derived products suitable for further analysis are presented.
