The winds effect on water under the ice

[Jbone]

What is the winds effect on the water under the ice and could it compromise the ice? 100 km/hr+ about 2ft+ of ice with a one ton

It would appear that it could...

Is the entire body of water frozen over?
What is the air temperature?
What is the ambient temperature range?

The body of water in the video is on the ocean, so winds and tidal forces at sea will affect the ice.

Chinook winds have the special property of being not only warm, but extremely dry. Not all chinook winds are above zero, but are all dry. So, there may be some sublimation in high wind conditions. If the ice is snow-covered, this is an unlikely issue.

If the air temperature is below zero, I doubt that the wind will affect the ice.

as long as your ice is good it shouldnt have much effect on it, Ive fished in 60-70+km and sat beside our truck.

Inside the shack the water was moving a good 6" up and down the hole, maybe a chance for the truck to break through with the waves? Was the worst conditions yet and hadn't asked many people about it

This could be cause of traffic on the lake, was there a few trucks driving around?.

Lol no way man, only crazies out there that day

An ice physicist I knew (described it as timpanic),, I will dig up a paper by him and post it.

First off the body of water in the video is Lake Superior and not the ocean.

Secondly...

"This Great Lake doesn't have tides like the {ocean;} however, periodically the water levels rise and fall by as much as one foot due to a phenomenon called a 'seiche' (SAYSH, a French word that means 'to sway back and forth'). This happens when water piles up on one side of the lake because of wind or high barometric pressure and then shifts back to the other side. Small seiches occur all the time, but sometimes strong ones can cause ships to bang together in harbors, or leave them high and dry for a few minutes."

So the 4' swells on the ice clearly indicate that these results could be repeated on smaller lakes (though unlikely).

Cheers.
