A truck carrying cars is not an aggregate though, at least not in the same sense here.  A flight of geese would be closer to a decent concept of aggregation I think.

The UA change is good except I would invert the colors.  This one makes it look like an emitter in the sky under a rain cloud cover.  Or, maybe put some sort of simply boat to show it's water.

To get some more inspiration, I have attached two alternative pictures.

I don't associate aggregates with groups of people and I like to see some water in the underwater acoustics icon.
