1. 1. Identifying subarctic river thermal and mechanical ice break-up using seismic sensing

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Stefania Ursica; [2021]
   Nyckelord :Ice break-up; River ice; Subarctic; Thermal melting; Mechanical break-up; Freeze-up; Environmental seismology; Seismic signals;

   Sammanfattning : River-ice break-up in high-latitude regions, despite its brevity, is a fundamental process, representing the most dynamic and complex period of fluvial processes. Moreover, ice break-up has significant cascading ecological effects, with a different severity for mechanical vs. LÄS MER

3. 2. Wisdom-volkano : a novel tool based on open GIS and time-series to analyse and share volcanic data

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Fulgencio Sanmartín; [2016]
   Nyckelord :GIS; volcanic eruption; interferogram; time-series; seismology; GNSS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

   Sammanfattning : Active volcanoes threaten life around. In order to predict their eruptions earlier and mitigate their hazards, several variables must be observed and compared. Geographical information systems (GIS) combine different geospatial images from remote or local sensing. However, GIS often miss how maps change during the time. LÄS MER
