1. 1. Can ancient pathogens emerging from glaciers and permafrost reach Europe by aerosolization?

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Anna Bruhn; [2023]
   Keywords : Ancient pathogens; Greenland; Aerosolized pathogens; Aerosol transport; Earth and Environmental Sciences;

   Abstract : Glaciers and permafrost capture bacteria and viruses when they form, which can be suspended for millennia. This includes long since extinct pathogens which are functionally novel. As polar regions get warmer these pathogens will emerge and spread through the local ecosystem, potentially altering it. READ MORE

3. 2. Teleoperation of an Autonomous Ground-Penetrating Radar for Non-Destructive Surveying: Design and Implementation

   University essay from Umeå universitet/Institutionen för fysik

   Author : Rasmus Beyer; [2023]
   Keywords : Autonomous; GPR; Robotics;

   Abstract : A lot of features that need to be scanned underground should not be disturbed, from waterlines to unmarked graves. A non-invasive way of probing underground is Ground-Penetrating Radar (GPR). GPR finds differences in materials with radar waves. However, GPR is human-operated and its position is generally determined with a GPS. READ MORE

4. 3. Glacier front variatons in Sweden: 2015-2022

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Martin Houssais; [2023]
   Keywords : Swedish glaciers; Glacier front variation; Remote sensing; MaQiT; Sentinel-2; Handheld GNSS; UAV photogrammetry; Total station;

   Abstract : This study aims at increasing the amount of data available on recent past Swedish glacier front variations, at improving the knowledge on the present behavior of these glaciers, and at contributing to the defnition of the guideline for future of glacier front observations in Sweden. To do so, the study proposes Sentinel-2 based yearly front variation measurements for 22 Swedish glaciers between 2015 and 2022, calculated based on the multicentreline approach of the MaQiT tool.
