1. 1. Three-component digital-based seismic landstreamer : Methodologies for infrastructure planning applications

   Författare :Bojan Brodic; Alireza Malehmir; Christopher Juhlin; André Pugin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; landstreamer; multicomponent seismic; shear-waves; surface-waves; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

   Sammanfattning : To support urban infrastructure planning projects, along with various other near-surface applications, a multicomponent landstreamer was developed. The landstreamer was built with broadband (0-800 Hz), three-component (3C) micro-electro-mechanical system (MEMS) sensors. LÄS MER

   Sammanfattning : Near surface seismic methods have the potential for mapping theoverburden and bedrock in the Nordic environment. They can provideeffective information about shallow glacial deposits and groundwaterresources in Sweden. LÄS MER

5. 4. Seismic investigations and physical property studies of natural resources in Finland and Sweden : Efficient exploration of groundwater and mineral resources

   Författare :Georgiana Maries; Alireza Malehmir; Christopher Juhlin; Musa Manzi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; seismic refraction; esker; glacial sediments; iron-oxide; hardrock; efficient exploration; physical property; forward modeling; seismic quality factor; Finland; Sweden; Bergslagen;

   Sammanfattning : Natural resources, such as mineral deposits and groundwater in particular, are crucial for our society, as the world prepares itself for a smooth transition towards green technologies and decarbonization. Apart from extraction and use, innovative mineral exploration solutions are needed to complete the full value chain and to achieve the sustainable development goals. LÄS MER
