Welcome, Brassman.
This is an interesting post. I don't know the answer, but there are some very smart aeration people here who will almost certainly be able to help.
A few quick questions to give the experts a bit more info:
How big is the bay?
How deep? [Or how shallow?]
Is it fed by runoff from a stream or creek, or is there some other way for a lot of organic material to wash in?
Does it have a lot of algae, plants, or other greenery?
Sorry for all the questions, the more info they have, the better equipped the experts will be.

Aerobic bacteria will probably be fine if you aerate at night, as there's likely to be a lot of photosynthetic production of oxygen during the day, if you have plants, algae etc.
