The ice is in smaller pieces today and there is more open water than last time we flew. | ||||
There is still an amorphous N-S fabric to the lead structure on the large scale. | ||||
The ice is all ponded or draining except for a few flat areas. | ||||
Pressure ridges much less obvious from the air |
