Book Review: Getting Down to It; 50 Years of Subsea Success in Norway

, after completing his degree at the Norwegian University of Science and Technology (NTNU ), or NTU (the Norwegian Institute of Technology) as it was in 1972, he saw the emergence of a new industry, petroleum exploration, and went on to complete an MSc and then a PhD in petroleum technology and applied geophysics, also at NTNU. In fact, he’s the first Norwegian to have completed a PhD in the subject in Norway.The timing was fortuitous. He joined Norske Hydro in 1975, the same year that the company, Saga Petroleum and Statoil were drilling their first wells on the Norwegian Continental Shelf (NCS)

the USV are possible through the integration of the KONGSBERG & Hushcraft custom developed automation and software configuration in conjunction with KONGSBERG’s K-MATE common autonomous control engine.The HUGIN AUV, Chercheur, deployed by the SEA-KIT USV is owned and operated by Ocean Floor Geophysics (OFG). It is one of the best equipped survey and pipeline inspection AUVs in the world, with HISAS interferometric synthetic aperture sonar, multibeam, sub-bottom profiler, OFG Self-Compensating Magnetometer, water chemistry sensors, acoustic modem, and a state-of-the-art positioning system.

initiative will enrich the student experience at UM’s Department of Geology while supporting its mission to train world-class professionals for domestic or international careers in petroleum geosciences.The software will be used to teach quantitative seismic interpretation within the Exploration Geophysics module of the Department’s Master of Petroleum Geoscience program. It will also be used by undergraduates for final-year projects as well as MSc and PhD postgraduate students and lecturers for conducting and publishing high-quality research focusing on reservoir characterization and quantitative

has been shaped by the action of several geological processes in polar margins. The gullies are the main topographic structures “that enabled the geological reconstruction of INBIS channel,” noted Leonardo Rui, member of the Trieste National Institute of Oceanography and Experimental Geophysics (OGS) and first author of the study.“In particular,” Rui continued, “the structure and some traits of these formations –for instance, ratio between dimensions and incision depth- help understanding the possible formation mechanisms and the differentiation between gully-dominated

contract for The Norwegian Public Roads Administration, Statens Vegvesen (SVV), to perform geophysical mapping of a 5km2 area in Bjørnafjord in Norway. The project was executed using the Hugin AUV Chercheur manufactured by Kongsberg Maritime and owned and operated by Canadian company Ocean Floor Geophysics Inc. (OFG) in combination with the small survey catamaran GeoCat owned by DOF Subsea Norway AS.The aim of the work was to obtain the necessary basis for engineering design services for a bridge over Bjørnafjord in connection with the Ferry Free E39 project. The assignment included high-quality

his research yielded, but in the quality and diversity of the questions he considered. An ethos he expressed throughout his career was for scientists to take risks, pursue new directions, and embrace the educational value of failure.“Walter Munk has been a world treasure for ocean science and geophysics,” said Scripps Oceanography Director Margaret Leinen. “He has been a guiding force, a stimulating force, a provocative force in science for 80 years. While one of the most distinguished and honored scientists in the world, Walter never rested on his accomplishments. He was always interested

These include the University of Oldenburg’s work monitoring plastic debris in the North Sea and Spain’s coastal authority, Salvamento Maritimo, using SPOT Trace to devise oil spill disaster recovery procedures. The National Institute of Oceanography and Experimental Geophysics and the “Istituto di Scienze Marine” of the Italian National Research Council use SPOT Trace to study surface currents in the Mediterranean and the University of Miami Rosenstiel School of Marine and Atmospheric Science has used large quantities of SPOT Trace satellite trackers also
