Surfing is a major industry in Australia, contributing $11billion to the economy. It has high active participation levels; but locations with good surfing conditions are limited and becoming crowded. New technologies, such as the circular-track wave pool, are required to provide safe environments for surfing with controllable high quality waves. The research in this proposal will considerably advance knowledge of wave mechanics; provide the ability to design a commercially-viable wave pool and ensure the Australian surfing industry and sport continue to expand. The project will thus result in major scientific, economic and social benefits for Australia.Read moreRead less
Submarine explosive eruptions of silicic magma: constraints on products and processes from modern sea-floor examples, ancient successions and experiments. Volcanoes are common on the sea-floor. Many have been the sites of devastating explosive eruptions throughout Earth history, producing thick layers of pumice and volcanic ash in both modern and ancient ocean basins. None of these events has been witnessed, hence, little is known about submarine explosive eruptions and the associated volcanoes. ....Submarine explosive eruptions of silicic magma: constraints on products and processes from modern sea-floor examples, ancient successions and experiments. Volcanoes are common on the sea-floor. Many have been the sites of devastating explosive eruptions throughout Earth history, producing thick layers of pumice and volcanic ash in both modern and ancient ocean basins. None of these events has been witnessed, hence, little is known about submarine explosive eruptions and the associated volcanoes. This detailed, multidisciplinary study will link exploration of modern explosive sea-floor volcanoes (western Pacific Ocean), field-work on older, submarine volcanic formations (Japan, Greece) and experiments that simulate explosive eruptions and their products. The results will elucidate sea-floor explosive volcanism and its contribution to the geology of ocean basins.Read moreRead less
