Here are photos of the underwater viewing areas. If they are in the right order than the first one is of the exhibit in the picture above and the second photo shows the second exhibit (in the background of the above photo).
Personally, I don't like this enclosure, as it is not very big and it has no place where the bears can hide from the public or where there is a large shady area, when it is warm.... So maybe it looks like polar bear habitat, I don't find it well suited for this bears....
