Anyone know how bubbles get trapped like that?

Ponds and such freeze from the surface downward. Even with ice on the top, there is movement of the water underneath. I assume that bubbles get created in the current and get trapped by the ice above which freezes more and more downward.
This is my guess...

A few years later, still in Holland, we were on a frozen lake - Dutch sweetie on skates, me on a converted sled (wrapped in blankies and carrying the thermos and cake... as I can't skate) and he was pushing me along when it went CRAAAAAACK! in all directions, in a star pattern with me in the middle. He said "oooh, that's not good" and we headed back. So there is CRAAAAAACK! and then there's CRAAAAAACK!
Not all crack is good ice it would seem.

how bubbles get trapped like that
Temp get cold. Water freezes and produces 1/2 inch of ice. Bubbles of gas from lake bottom rise and get trapped underneath the ice layer. The next night when it gets cold again, more water freezes and ice becomes thicker forming on the ice above it but not on the bubble except at the edges. The next day, more gas bubbles up getting trapped again. Repeat over many days and night all winter long..

Thank you, Dougie. Welcome.

Welcome Dougie - clear and concise explantaion.
Although I had to reread it a few times. Bubbles in my brain were making it hard to visualise.

Get a load of Dougie with the believable explanation.

Another possible explanation is that they are the gaseous diffusions from the GI tract of hibernating furred arctic mannatees. As they slowly digest stored fat, it eventually works its way out and floats to the surface. Some Inuit tribes use it as fuel by drilling a small hole in the top of the ice and lighting it. As the gas burns, it goes down and opens up the underlying bubbles. Really.
