Carlo commented on the picture of skim ice (a portion shown to the right) that,<\/p>\n<blockquote>\n<p>The ice crystals in the &#8230; photo show a conspicuous preferred orientation with long elements left-right in the image. This indicates that forces at the water&#8217;s surface were not equal in all directions. When I mentioned this to Alistair, he suggested that there may have been a very gentle swell impinging on the shore. This would tend to orient the free-floating frazil with their long dimension parallel to the shore, accounting for the observed directed pattern. Neat!<\/p>\n<\/blockquote>\n<p>Yesterday, I saw it happening. Frazil along the shore was becoming oriented by waves.<\/p>\n<p>First, an overview. Waves with whitecaps (left) are washing into a bay. There is ice along the shore where the water has washed up from earlier waves and frozen. The frazil is in the centre.<br \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9771\" onclick=\"return false\" onmousedown=\"return false\" alt=\"\" src=\"https:\/\/blog.kootenay-lake.ca\/wp-content\/uploads\/2014\/02\/frazil140206bs.jpg\" width=\"720\" height=\"480\" \/><\/p>\n<p>A closer view shows the frazil to be grains of ice floating on the water and moving up and down with the waves.<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9770\" onclick=\"return false\" onmousedown=\"return false\" alt=\"\" src=\"https:\/\/blog.kootenay-lake.ca\/wp-content\/uploads\/2014\/02\/frazil140206cs.jpg\" width=\"720\" height=\"480\" \/><\/p>\n<p>This view, elsewhere along the shore, looks directly into the approaching frazil-carpeted waves.
