Lessons from the wreck of the Rena

University of Waikato Marine Ecologist Dr Phil Ross has done hundreds of dives researching the twisted wreck of the Rena which sits on the Astrolabe Reef (Otaiti). This week marks 10 years since New Zealand's worst ecological marine disaster, and while monitoring has shown the amazing capacity of the ocean to recover, researchers say it has also demonstrated the impacts of overfishing delicate reef systems.
