1. 16. Analysis of Observed Discrepancies in Precipitation Measurements in the Complex Terrain of East-Iceland

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

   Author : Páll Ágúst Þórarinsson; [2021]
   Keywords : Precipitation; precipitation measurements; weather observation; complex terrain; weather regimes; Iceland; Nederbörd; nederbördmätningar; väder observationer; komplex terräng; vädersituationen; Island;

   Abstract : Spatial distribution of precipitation in complex terrain can be very uneven and there are many factors to consider when studying it. The goal of this study was such a problem; to analyse the difference in observed annual precipitation in the complex terrain of Seyðisfjörður, a fjord in East-Iceland. The study was carried out in three parts. READ MORE

3. 17. Decreasing organic nitrogen concentrations in European water bodies - links to organic carbon trends and land cover

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Alexis Cazorla; [2020]
   Keywords : geography; GIS; physical geography; organic nitrogen; organic carbon; land cover; eutrophication; Europe; Earth and Environmental Sciences;

   Abstract : European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs.

4. 18. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Julika Wolf; [2020]
   Keywords : Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

   Abstract : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. READ MORE

5. 19. Archaeobotany in the 4th Dimension: Visualising Specialist Data in a 3D GIS

   University essay from Lunds universitet/Arkeologi

   Author : John Paul Howorth; [2020]
   Keywords : 3D 4D GIS; Archaeobotany; Uppåkra; Digital Archaeology; Visualisation; History and Archaeology;

   Abstract : Archaeobotany and GIS are closely linked with archaeology, it is hard to imagine a modern archaeological investigation without them. The two appear to complement each other. GIS links highly complex sets of data with space, and offers a range of analytical tools. READ MORE

6. 20. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Ellen Grace Soroka; [2020]
   Keywords : Physics and Astronomy;

   Abstract : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. READ MORE
