Moss newspaper – Do you see this plane flying low, that's the reason

The Geological Survey of Norway (NGU) conducts summer surveys in parts of Østfold, Akershus, Oslo and southern Hedmark. The measurements will provide better knowledge of the bedrock and provide important data on opportunities for mineral resources and building materials, reports NGU.

Easy to recognize

For best results, measurements are made at low altitude. NGU has received permission from the Civil Aviation Authority to fly at 60 meters altitude. In steep areas, the measurement height will be significantly greater

The aircraft that will perform the measurements is easy to recognize; They are custom made just to be a measurement plane and have a long tail. It is the Canadian company Novatem that performs the flights on behalf of NGU. The measurements are made in a Crane Belt at Halden and the flights will last during the summer and the autumn

The plane will be based at Moss Airport and will cross oriented profiles. in the west and east at 250 meters and north-south. crossings 5 ​​km away. This means that planes fly at a height and in a pattern that is noticed by people in the area

This is the Measure on

A task is to map the natural uranium content in the rock to assess the hazards of radon and check the cesium fall residue after the Chernobyl accident. Magnetic and radiometric measurements of the air can characterize the rock and thus reveal rocks rich in minerals. The measurements can also be used to interpret possible erosion hazards and other problematic rocks in the future construction of roads and tunnels.

The bedrock of uranium must in some cases be treated as a special waste. On the other hand, it develops heat and can, under favorable conditions, be interesting for the extraction of energy from the depths of the Earth's crust. Knowledge of deep structures is used in conjunction with other geological and geophysical data to create a 3D model for southeastern Norway and can provide information on how and when the mountains of southern Norway have taken birth. .

Important knowledge

Currently, parts of southern Norway are not mapped with sufficient geophysical data, whereas, for example, Sweden's coverage is over 90%, reports NGU. This project will help increase coverage in southern Norway and improve knowledge of the geology and resource potential in the region. The results will eventually become public as part of the NGU Geophysical Database.
