Mannen is an unstable rock slope in the Romsdal Valley in the Møre og Romsdal County (western Norway). The slope is under continuous monitoring since 2009 by the Åknes/Tafjord Beredskap IKS. As part of the detailed site investigations, two more than 130 m deep, vertical cored boreholes have been drilled in 2010 and 2011.
The Geological Survey of Norway (NGU) operates a mobile gamma ray spectrometer system which can be used in nuclear emergency situations to determine the location and type of orphan sources, or the extent and type of fallout contamination. The system consists of a 20 litre (16 litre downward and 4 litre upward looking) RSX-5 NaI detector and spectrometer, and can be mounted in fixed wing aircraft, helicopters, or vans/cars as appropriate.
Catastrophic failure of large rock slopes in Norway has several times per century led to rock avalanches or large rock falls, which impacted into settlements directly, but also caused either a displacement wave when impacting a water body or damming of narrow valleys with often fatal consequences. Such events will also occur in the future.
The purpose of this report is to review how bathymetric data may be used to characterize seabed terrain with a view to benthic habitat mapping This study was led by the Geological Survey of Norway with contributions from the Geological Survey of Denmark and Greenland, The Geological Survey of Ireland and the Royal Belgian Institute of Natural Sciences.
The Geological Survey of Norway has compiled an inventory of hard rock aggregate deposits in coastal Norway. This report contains a catalogue of Norwegian coastal quarries presently in production and exporting, as well as of potential areas along the coast of South-Central Norway and Finnmark. In 2011, 21 million tonnes of aggregates were exported to Europe, and about 1,4 million tonnes were used by the offshore oil and gas industry on the continental chelf.
The Geological Survey of Norway and the Norwegian Petroleum Directorate established the TWIN Project (Tropical Weathering In Norway) in 2009 to improve the understanding of deep weathering on mainland Norway as well as offshore. All known reports of deep weathering in Norway have been reviewed and registered in a GIS database.
The MAREANO (Marine AREA database for NOrwegian waters) seabed mapping programme generates a wide range of products, including sediment and benthic biotope maps. Production of these maps relies heavily on full-coverage multibeam data (bathymetry and backscatter) which have revealed the seabed in unprecedented detail, and which form the basis for geological interpretations and the identification of seabed terrain of ecological relevance.
The project is aimed to achieve a better understanding of shallow geological/seabed conditions and processes to support technical and environmental aspects of exploration and production along the western margin of the Hammerfest Basin and Loppa High, and in the Tromsø Basin/Ingøydjupet area. The project has had the following subgoals: - Detection of water column gas anomalies at selected pockmark locations - Identification of neotectonic features The project has the following results: - A t
The Nordkinn Peninsula consists of a series of Neoproterozoic fluvial, cross-bedded sandstones belonging to the Kalak Nappe complex wich are derived from basement terraines of the Fennoscandian shield (Roberts, 2007). On first glance the area appears to hold little promise for mineral exploration.
