 Hi everyone I'm Melanie Olson from the Australian Institute of Marine Science and in this talk I'll be discussing some of the considerations you have to think about for deploying drones in marine operations for reef marine parks such as the Great Bay Reef Observations. So in this talk I'll be addressing factors such as safety to both people and also the equipment over some of our operational zones are quite harsh and remote and I'll be looking at the regulatory compliance so we have to integrate drones into a much larger observation framework that's both aerial and underwater and surface and other aspects. So we're looking into how we balance that layered deployment framework and finally I'll be talking a little bit about what are the considerations you have to think about such as landing on a ship which is a moving platform and how do you mature technology in a control framework so you're mitigating the risk to failures as the engineering program develops and develop a product that you can deploy operationally in a safe and efficient manner. Thank you.
