Halfmoon Biosciences have been conducting independent research at the Houtman Abrolhos since 1991.

Using seabirds as an indicator of the health of the marine environment, we have shown how long-term change in the marine environment may impact seabirds, and how seabirds may be used as an indicator of this change.
