I think marine enclosures will be fairly similar to what was displayed in Jurassic World, with barriers near the water side for guest's to observe...maybe even dips for guests to see marine creatures under the water line? However, the Dinosaur Aviary will be an interesting concept...if it is a building, i would imagine it to be fairly huge to accommodate flying space and for us to see them flying. However, thus far we haven't been shown anything to indicate an aviary.
