Here is a post with no fish or fishing. The Norwegian research vessel “G.O.Sars” is now on a survey in the Antarctic Ocean. The vessel started the survey in Cape Town and then headed south. After days of sailing in the same flat and wet “landscape”, something special was observed. The crew spotted an iceberg, but it did not look like an ordinary iceberg.
The iceberg seemed to be marbled. The iceberg had dark stripes or layers in between. Is it made by ice crystals with different density, or ice with different density of salt? Are the dark layers made of ice with ash; proof of volcanic activity thousand of years ago? Maybe some readers know the answer? The photos were taken by Øyvind Tangen two days ago.
