The measurement techniques for polar seas were summarised in an article

A recent research article complies the measurement techniques of various satellite altimeters on ice-covered seas.

The water levels and the thickness of ice in seas that freeze over in winter, such as the Arctic Ocean and the Baltic Sea, are regularly measured by satellite. The article, which was published in the journal Remote Sensing, is a comprehensive review of how cracks in the middle of sea ice are identified, and how geophysical variables, such as water levels and thickness of sea ice, are calculated.

Researchers at the Finnish Meteorological Institute took part in writing the article together with those from eight other European research institutes.

The thickness of polar sea ice in 1–7 April 2019 due to the data produced by CryoSat-2 and SMOS satellites.
