Differential freezing ice

Here is rain water pails area in our garden.

I found out differential freezing ice in the area yesterday.
It was very cold.

This picture is freezing ice of pailful water.


But this one is another freezing ice in a pail.


In this case, the pail did not have full water like this.

What difference condition was there between them except amount of the water?

Do a test: put full buckets in both locations. If one freezes more than the other, then you have different microclimates!

You have a good suggestion.
OK I will do the test.
