Cracks in sea ice
I have seen a lot of cracks in each ICECAP lately in 5 below temperature at night and 0 temperature in the afternoon. I got over four cracks yesterday. The bigger one is between 70 and 80 centimeters wide. Dark and black sea water was a little bit scary for me.
To get over cracks of this size is too dangerous. I look for another narrow crack and get over it. As sea water was frozen over thinly, when I ponged the surface with a stock, it was broken easily and I was able to see how thick sea ice is. There is no 2-meter-thick sea ice around here.
As the route this time is sea ice between two islands, it canft be moved by strong wind and an ocean current like Arctic ocean. ICECAPs have been drifted from the near mountains. So, they can be seen all over. When an ICECAP is moved by too much strong wind, the ICECAP must crack sea ice. I was able to see a long crack in sea ice leading from an ICECAP.
Sea surface will be spreading over day by day.
