A historical review of gravimetric observations in Norway
Pettersen, Bjørn Ragnvald (Journal article; Peer reviewed, 2016) -
Geodetic observations and modeling of gravity field, sea level, and ocean dynamics in the Norwegian coastal zone
Ophaug, Vegard (Phd Thesis;2017:24, Doctoral thesis, 2017)Geodesy can contribute to a quantitative understanding of ocean circulation variability at northern high latitudes, which is crucial to environmental and climate-related studies. Coastal ocean dynamics has gained recent ... -
Investigations of surface loads of the Earth - geometrical deformations and gravity changes
Breili, Kristian (PhD Thesis;2009:25, Doctoral thesis, 2009)This thesis addresses deformations and gravity changes due to surface loads like the ocean tides, hydrology and glaciers. These phenomena are discussed in light of height and gravity observations collected by GPS and ... -
Merz Telescopes at the University Observatory in Christiania, Norway
Pettersen, Bjørn Ragnvald (Peer reviewed; Journal article, 2019): Four telescopes with optics by Merz in Munich were acquired for the University Observatory in Christiania between 1840 and 1882. Two had equatorial mountings by Merz, one by Repsold, and one by Olsen. We describe the ... -
Sea level, ocean currents, and vertical land motion along the Norwegian coast
Idžanović, Martina (PhD Thesis;2019:80, Doctoral thesis, 2019)Ocean circulation plays a fundamental role in climate and sea-level related studies due to the ocean’s large heat-storage and transport capacity. Ocean circulation can be derived from numerical ocean models, which might ... -
Vector corrections in scalar gravimetry
Bugten, Magne (Master thesis, 2018)Advances in airborne gravimetry have made increased use of global navigation satellite systems (GNSS) to successfully model unwanted accelerations, caused by the motion of the aircraft. Installation of GNSS receivers in ...
