Geophysical ground measurements, gravity (display service)

Geophysical ground measurements, gravity interpolated shows the variations that exist in Sweden's gravity field, expressed as Bougueranomali. From point-by-point measurements of gravity throughout Sweden, Bougueranomalier (mGal) has been calculated in the reference field RG82. These have since been gridded with the cell size 500m x 500m. Measurements of gravity can be used to map variations in mass distribution in the Earth's crust. These variations are due to differences in the composition of the bedrock.
