Clearly in the image that is NOT open water.
Those are melt off pools on top of thicker ice that would prevent any ship passage.
Clearly the submarines looked for thin ice and punched up through ice that still covered the Arctic Ocean.
While things were already warming up from AGW since 1840, in 1987 there clearly was still no open passage through the Arctic ice.
What does that have to do with the picture at the North Pole?
That is the North Pole in March before the Summer thaw

You assessment is not accurate.
The captain of the USS Skate explained that ocean movement of the ice would crack open fissures, but that was not melt-off and it quickly refroze over. So clearly it was much, much colder than compared to now.
About 11 degree colder in fact.

“the Skate found open water both in the summer and following winter. We surfaced near the North Pole in the winter through thin ice less than 2 feet thick. The ice moves from Alaska to Iceland and the wind and tides causes open water as the ice breaks up. The Ice at the polar ice cap is an average of 6-8 feet thick, but with the wind and tides the ice will crack and open into large polynyas (areas of open water), these areas will refreeze over with thin ice. We had sonar equipment that would find these open or thin areas to come up through, thus limiting any damage to the submarine. The ice would also close in and cover these areas crushing together making large ice ridges both above and below the water. We came up through a very large opening in 1958 that was 1/2 mile long and 200 yards wide. The wind came up and closed the opening within 2 hours.

6 inches is less than 2 feet thick, the video shows 6 to 10 inches. The video was taken in March which is right before the beginning of the Summer thaw the point of MOST ice. You really need to get a grip, the North pole ice cap always moves and heaves ice cores would never ever show sedimentary layers. That happens on glacial ice. But you go right on making up stuff like Gore did, you are not mocking me
Didn't you even read?
It clearly said an average of 6 to 8 feet of ice over the whole Arctic region.
The video does not show 6 to 10 inches on average.
If there is a recent fissure, you can get thinner ice, but it quickly thickens up through refreezing from the cold.
The POINT is that now open water is NOT from fissures, but by MELTING!
Can't you understand the incredible difference in temperature?
The Arctic is now 11 degrees warmer, on average.
