Reef Climate Adaptation Research and Technology
The authors describe research into technological means for addressing two consequences of climate change for coral ocean acidity and increasing sea surface temperatures leading to coral bleaching. Technology for a multi- integrated response is proposed.
Sea surface temperatures can be monitored via satellite and on-line telemetry. Technology for moderating sea surface temperature spikes is based on pumping deeper cool seawater over coral reefs. The technology proposed includes plastic collapsible pipelines that can be deployed like oil spill booms with flat disc pumps and renewable energy devices (tidal turbines) to power the pumps.
The technology for counteracting increasing ocean acidity on coral reefs is based on the Accelerated Weathering of Limestone (AWL). It is proposed that an acceleration of the natural process that restores the carbon balance, can be realized using a modified electrolyzer powered by renewable energy. The AWL process sequesters CO₂ and produces H₂ while generating a buffer solution that increases reef pH and also provides alkalinity to feed reef and shellfish calcification.
The AWL buffer solution will be distributed where required using the same renewable energy powered pumps and pipelines as used to mitigate sea surface temperature spikes. The AWL process will operate continuously but can be interrupted whenever the pumps and collapsible pipes are required to avoid potential coral thermal bleaching events. Dual use improves affordability.

Director, EnGen Institute, Melbourne, Victoria, Australia
William Hollier is a physicist and systems scientist developing closed cycle life-support and environmental systems. Having worked in the Royal Australian Navy Research Laboratories, CSIRO, and Melbourne and RMIT Universities he specialized in complex systems analysis, systems design and design generation. He is now the director of EnGen Institute, a not-for-profit research and education body established in 1992 and oversees the three principal areas of research – engineering, environment and energy. The engineering program applies generative systems for design automation. The environment program researches the development of life support environments and systems, and the energy program researches renewable energy systems, in particular, ocean current and hydrogen energy systems. EnGen Institute commenced tidal energy research in 1996 and is collaborating with the Australian Maritime College, The University of Queensland and The University of Melbourne to develop tidal power systems.

Program Manager, Great Barrier Reef Ocean Observing System, Information Technology Service Group, Australian Institute of Marine Science, Townsville, Queensland, Australia
Scott is currently the project manager of the Great Barrier Reef Ocean Observing System (GBROOS) project which is a geographic node of the Australian Integrated Marine Observing System (IMOS) project. This role includes project management of the overall project, leading the Sensor Network component of GBROOS and taking overall responsibility for the data management for the project. Scott’s focus is the development and deployment of sensor networks on a number of reefs and the management, access and use of the real time data these systems generate. Part of this is the development of sensor network technologies for generalised coastal zone monitoring.
