Little evidence of great glacial floods – kettle holes on Skeiðarársandur (S Iceland)
SfM technique used: a) the location of individual film frames to the landform against the background of the point cloud, b) scaled point cloud of the kettle hole with land cover, c) a digital terrain model in 3D view, resolution 0.1 m × 0.1 m, vertical exaggeration 1.5, kettle hole diameter 12 m; author: J. Szafraniec

As part of the individual scientific activity of Dr Joanna E. Szafraniec and thanks to the support of the Center for Polar Studies, a research trip to Iceland took place at the end of June 2021, to the forefield of the Skeiðarárjökull glacier. The expedition aimed to set up a network of measuring points located in kettle holes. The local outwash plain is dotted with these landforms. They were formed after catastrophic glacial floods (jökulhlaup).
The results of the observations will be used to calculate the sedimentation rate and the role of plant succession in this process. Moreover, the research results will be used in the analysis of similar forms occurring in the Polish Lowlands. The established morphometric relations and the calculated sedimentation rate will allow us to determine the Polish landforms’ age and to present the scenario of Poland’s deglaciation at the end of the Pleistocene, i.e. under conditions of significant climate changes. The photogrammetric Structure from Motion (SfM) technique was also tested during the field studies to obtain a high-resolution digital elevation model of the tested landforms.

The third State of Environmental Science in Svalbard (SESS) Report
On January 11, 2021, during the virtual event: Polar Night Week https://sios-svalbard.org/PolarNightWeek the promotion of the third State of Environmental Science in Svalbard (SESS) report took place.
SESS reports summarize the current state of knowledge on the Arctic environment’s key parameters and their interdependence. They are an essential source of information on the state of the natural environment of Svalbard, also serving as a platform of knowledge available to the entire community, necessary for the sustainable development and protection of the Arctic environment.
International and multidisciplinary teams work on the reports, chaired by scientists from SIOS (Svalbard Integrated Arctic Earth Observing System) member institutions. The third report’s preparation has also been attended by the University of Silesia in Katowice employees –Elżbieta Łepkowska from the Centre for Polar Studies and Michał Laska from the Institute of Earth Sciences.
Elżbieta Łepkowska is the co-author of the article entitled “From land to fjords: The review of Svalbard hydrology from 1970 to 2019 (SvalHydro)”, about the evolution of Svalbard hydrology in connection with recent climate change.
The article entitled “Scientific Applications of Unmanned Vehicles in Svalbard (UAV Svalbard)”, co-authored by Michał Laska, focuses on the examples of the use of unmanned vehicles (aerial, land and underwater) for detailed research of the natural environment of this part of the Arctic.
The above and other articles of this report can be found here: https://sios-svalbard.org/SESS_Issue3
Merry Christmas and Happy New Year 2021 !
