#Oi2020 History

Scripps Center for Marine Archaeology (SCMA). Co-led by Scripps Oceanography and Department of Anthropology, the new center was designed to investigate the relationship between human societies and marine environments. The center was co-founded by Scripps geophysicist Walter Munk and former Institute of Geophysics and Planetary Physics Green Fellow Damien Leloup, who started his research career onboard the vessels Calypso and Alcyone, while working alongside Jacque Cousteau. As part of a funding effort, Munk and Leloup managed to raise more than $400,000 in see donations, and thus secured approval to commence

of mapping and proving deep sea mineral deposits by the Norwegian Ministry of Petroleum and Energy. Using multiple autonomous underwater vehicles (AUV), Ocean Infinity acquired a total of 3,900 kilometers of geophysical seabed data over the four-week expedition, assisted by experts from Ocean Floor Geophysics (OFG). At the same time, remotely operated underwater vehicles (ROV) were deployed to gather rock samples, and to take HD photographs and videos of mineral deposits.The information acquired has provided important geophysical data and seabed maps, with a resolution of one meter in water depths down

rich gravel piles the NPD has now mapped and taken samples from.The samples and the geophysical data will be analysed and interpreted and will form the basis for further evaluation and studies of the area.The data acquisition cruise was carried out by Ocean Infinity, with experts from Ocean Floor Geophysics and the Norwegian Petroleum Directorate. PhD candidates from the University of Bergen (UiB) and NTNU were invited on the cruise and they contributed with valuable knowledge

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
