1. 16. Glacial lakes in the Torneträsk region, northern Sweden, are key to understanding regional deglaciation patterns and dynamics

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Karlijn Ploeg; [2022]
   Keywords : deglaciation; glacial geomorphology; LiDAR; glacial lakes; Torneträsk;

   Abstract : The prospect of sea level rise due to melting ice sheets affirms the urgency of gaining knowledge on ice sheet dynamics during deglaciation. The Fennoscandian Ice Sheet serves as an analogue, whose retreat can be reconstructed from the geomorphological record. READ MORE

3. 17. Alternative fuels for Swedish short sea shipping and inland waterways: Techno-economic study

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Julien Maszelin; [2022]
   Keywords : Alternative fuels Comparison Short sea shipping Inland waterways Sweden Biofuels Fischer-Tropsch Methanol Hydrogen Ammonia Fossil fuels Sustainable transportation;

   Abstract : Climate change is raising huge challenges for all industries worldwide. It is mainly due to anthropogenic activity and energy consumption which is the cause for emissions of greenhouse gas (GHG) among other environmental impacts and is expected to have huge impact on our societies globally.

4. 18. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Daniel Estmark; [2022]
   Keywords : Perennial Firn Aquifer; Glacier; Svalbard; Mass balance; GPR; Lomonosovfonna; Flerårig firn akvifär; glaciär; Svalbard; massbalans; GPR; Lomonosovfonna;

   Abstract : As the climate is changing, there are clear impacts on the mass balance of glaciers. A glacier can be defined as the result of sufficient accumulation, in the form of snow and rain, compared to its ablation, the different types of glacial loss, a balance that then determines the size of the glacier.

5. 19. Creating a semantic segmentationmachine learning model for sea icedetection on radar images to study theThwaites region

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Carmen Fuentes Soria; [2022]
   Keywords : Synthetic Aperture Radar SAR ; Machine Learning ML ; Semantic segmentation; Convolutional Neural Networks CNN ; Thwaites Glacier;

   Abstract : This thesis presents a deep learning tool able to identify ice in radar images fromthe sea-ice environment of the Twhaites glacier outlet. The project is motivatedby the threatening situation of the Thwaites glacier that has been increasingits mass loss rate during the last decade. READ MORE

6. 20. Cost Efficient Scrap Metal Sourcing

   University essay from Lunds universitet/Teknisk logistik

   Author : Sophia Sandström; Sofia Ivarsson; [2022]
   Keywords : Scrap sourcing; Scrap logistics; European scrap market; Sea freight strategies; Bulk shipping; Technology and Engineering;

   Abstract : The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. READ MORE
