1. 1. Mapping bathymetry : From measurement to applications

   Författare :Benjamin Hell; Martin Jakobsson; Michele Rebesco; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean and coastal mapping; Digital Bathymetric Model; Geographical Information System; Applications of bathymetric data; Baltic Sea; Arctic Ocean; Seafloor morphology; Ocean circulation; Other earth sciences; Övrig geovetenskap; Marine Geoscience; marin geovetenskap;

   Sammanfattning : Surface elevation is likely the most fundamental property of our planet. In contrast to land topography, bathymetry, its underwater equivalent, remains uncertain in many parts of the World ocean. Bathymetry is relevant for a wide range of research topics and for a variety of societal needs. LÄS MER

3. 2. Uncovering Ocean Mixing near Rough Bathymetry : Using Broadband Acoustics

   Författare :Julia C. Muchowski; Christian Stranne; Martin Jakobsson; Lars Umlauf; Lars Arneborg; Fer Ilker; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean mixing; diapycnal mixing; broadband acoustics; turbulence microstructure; rough bathymetry; stratified flow over obstacles; observations of turbulent mixing; Baltic Sea research; maringeologi; Marine Geology;

   Sammanfattning : Ocean mixing related to rough bathymetry is highly dynamic and exhibits large spatial and temporal variability. Therefore, established in-situ methods as well as numerical models often lack the resolution to capture this type of mixing. In this thesis, acoustics are used to observe, map and quantify stratified mixing at unprecedented resolution. LÄS MER

5. 4. Modelling water and solute flows at land-sea and land-atmosphere interfaces under data limitations

   Författare :Yoshihiro Shibuo; Georgia Destouni; Jerker Jarsjö; Clifford Voss; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Submarine groundwater discharge; unmonitored flows; catchment hydrology; evapotranspiration; bathymetry; GIS; Aral Sea; nuclear waste repository sites; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Sammanfattning : Water and vapour flows from land to sea and the atmosphere are important for water resources, coastal ecosystems and climate. This thesis investigates possible methods for modelling these flows under often encountered unmonitored hydrological conditions and data limitations. LÄS MER

7. 5. Response of Bolivian Altiplano Lakes to Seasonal and Annual Climate Variations

   Författare :Ramiro Pillco; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENSO; terminal lake; bathymetry; lake level; water balance; lake routing; paleolakes; climate change; precipitation pattern; intermittent rivers.; Desaguadero River; Lake Titicaca; Lake Poopó;

   Sammanfattning : The Bolivian Altiplano is situated between two mountain ranges, the western and eastern central Andes in South America. It has two major lakes, Lake Titicaca to the north, and Lake Poopó to the south, which both are important for the nature as well as for the living conditions on the Altiplano. The two lakes are the remnants of large paleolakes. LÄS MER
