New Study: Denmark Coast Has Been Expanding Seaward At A Rate Of +1.4 Meters Per Year Since 1900

By Kenneth Richard on 15. February 2024

Scientists have found evidence that the coastal land area grew (prograded) by 120 meters from 1900 to 1985 at a study site in central Denmark.

Per a new study, relative sea levels (RSL) in central Denmark were “~4.5 m higher than present between c. 6.6 and 5.9 ka ago.” After this highstand, RSL declined towards the present.

The 20th century rates of coastal expansion and retreating seas were similar to the declining RSL and progradation rates reached in the Middle Holocene.

If you go to the West coast of Jylland, you will see German coastal defences from WWII, 100m out to sea, but they were originally built on land.

  Could you provide a source where I can read more about this, Rob?

Hi Kenneth

Look up Vigsø WWII Battery on Google Maps. Lots of photos there.

Cheers

  Look up erosion assessment of the Vigso bay by one of the Danish universities. Apparently the construction of these bunkers only accelerated the erosion process over the last decades.

Do not forget that 15 thousand years ago Denmark was covered with more than 2000 meters of ice. After the Dryas period all this ice disappeared and the hydrostatic process of upwelling stated. It takes thousands of years to get equilibrated. This may explain why danish coasts are expanding. The same situation has been well documented for the Scandinavian peninsula
