Okay, can someone please decipher exactly what this image is supposed to indicate? I see what appears to be quite a bit of new ice, young ice and first year thin ice but have no idea how it should be interpreted. Is this good news, bad news, or simply the same old news we've been hearing for a long time?

Hi Don your looking at 2year old or better ice in the  brown  the rest is new Ice, shorefast ice and  open water. As the winter progressives  you will see the open water close up almost all the way down to St Paul  Island.

Thanks John. I suspect this is the normal cyclic nature of ice melting in the summer and refreezing in the winter months so it's nothing abnormal.

I keep hearing all this talk on one side talking about the receding glaciers and icecap yet on the other side that the arctic ice is growing rapidly. To a novice, it's all confusing and I'm not sure who to believe any longer.

My best to you & 73's

Ok Don  if you check that site weekly you can see the growth  or fluctuation in it as  storms  plow up the bearing. Thursday  they show  65 knot winds and 40 to 46 foot seas  for Shemya and Adak  and they say it going to  move some of the ice around in the straits. Guess no ice party yet between the Diomedes.
