Geodetic Journey

A precise high precision geoid is of fundamental importance when using satellite altimetry for oceanographic purposes.

The mean sea surface deviates from the geoid and this difference is a very valuable source of information for oceanographers when determining the ocean circulation and transport.

Increased knowledge of ocean circulation is also very important when studying climate change and will increase our abilities in making reliable predictions for the future.

In the Arctic, a high precision geoid combined with other geophysical data, will aid in determining the sea ice thickness.
