Service Description: This data shows planned, current and completed flight lines for TELLUS Airborne Surveys 2024.
Airborne surveys collect magnetic, radiometric and electromagnetic data.
The data were collected using an airplane. The airplane flies at 60 m flight height along lines that are 200 m apart.
Magnetic data are recorded at around 6 m intervals along the flight lines. The magnetometer system mounted on the airplane records the magnetic field strength of the rocks. The magnetic field changes depending on the type of rock beneath the aircraft. Iron rich rocks (for example, basalt) are strongly magnetic and have a strong magnetic field, while rocks with low iron content (for example, limestone) are weakly magnetic.
Gamma ray spectrometer data are recorded at around 60 m intervals along the flight lines. The spectrometer system mounted on the airplane records the number of gamma rays emitted per second by rocks and soils. The gamma ray intensity changes depending on the amount of Uranium, Thorium and Potassium in rocks and soil beneath the aircraft. For example, rocks such as granite contain a large amount of Uranium, Thorium and Potassium, while limestone rocks contain low amounts of these elements.
Electromagnetic data are recorded at around 6 m intervals along the flight lines. The electromagnetic system mounted on the airplane sends an electromagnetic signal (at different frequencies) into the ground and records the response of the ground returning to the system receiver. The response changes depending on the type of rock or soil that the electromagnetic signal meets. For example, graphite has a high response value (meaning it is a low resistivity rock) while limestone has a low response value (it is a high resistivity rock).

Subject: Planned, Current and Completed Flight Lines for TELLUS geophysical Airborne Surveys 2024.
From a plane, this survey measures the magnetic strength of rocks below, how electrical currents flow through different types of rocks and soils and the amount of natural radioactivity contained in rocks and soils below. This allows us to map different types of rocks, even in areas were rocks are covered by soil. The findings tell us about the rocks in the ground. This is useful if you want to drill for water or to help find minerals (materials taken from the ground used for things we need from mobile phones to the stones used to build roads and houses). The data can also be used by farmers to tell them about the soil. The data can also be used to help map radon gas.
It also helps find areas that have high or low levels of natural radioactivity. Knowing about the natural radioactivity of soils and rock is of use to farmers and scientists, telling them how the soil is formed and also the location of peat.
