2. 1. Ridged sea ice modelling in climate applications

   Author : Sebastian Mårtensson; Markus Meier; Kristofer Döös; Peter A. Lundberg; Frank Kauker; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic ocean; Baltic Sea; sea ice; ice dynamics; numerical modelling; climate; ice deformation; ice compression; physical and biogeochemical interactions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : This work aims to increase our understanding of the nature of large scale features of sea ice from a dynamics point of view.Sea ice plays an important part in the exchange of heat and humidity between sea and air and thus is an important component of the climate system. READ MORE

4. 2. Sea Ice and Ocean Environmental Applications of Spaceborn SAR

   Author : Sverre Thune Dokken; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radarsat; SSM I; ERS-1 2; ocean applications; sea ice applications; numerical models; SAR; Arctic Ocean; Envisat; climate change;

   Abstract : The worldwide focus on our changing environment has led to an increased need to observe and characterise a range of environmental phenomena. The Arctic Ocean is particularly sensitive to climate variations. READ MORE

5. 3. Modelling Microwave Backscattering from Sea Ice for Synthetic-Aperture Radar Applications

   Author : Anders Carlström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic-aperture radar; microwave; surface roughness; sea ice; backscattering models;

   Abstract : The spaceborne synthetic-aperture radar (SAR) is considered one of the key instruments for monitoring the ice cover in polar oceans and regional seas. This thesis is concerned with applications of electromagnetic scattering theory and SAR system theory for modelling the response of different types of sea ice in SAR imagery. READ MORE

6. 4. New methods and applications for interferometric GNSS reflectometry

   Author : Joakim Strandberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sea level; sea ice; GNSS; reflectometry;

   Abstract : The GNSS reflectometry technique has been proven to be usable for measuring several environmental properties, such as soil moisture, snow depth, vegetation, and sea level. As numerous GNSS installations are already installed around the world for geodetic purposes, the technique opens up a large data set for new analyses, complementing other environmental measurement campaigns.

7. 5. Mapping bathymetry : From measurement to applications

   Author : Benjamin Hell; Martin Jakobsson; Michele Rebesco; Stockholms universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE
