Global trends in oceanic wind speed and wave height. This project will determine whether winds and waves over the world's oceans have changed over the past 30 years. Such information is critically important in understanding global climate change, evaporation, air-sea interaction and to safely design and operate coastal and offshore facilities.
Wave-Induced Upper-Ocean Mixing. The wave-induced mixing is of principal importance for air-sea interaction models since heat capacity of 2-3m of the ocean water is equal to the capacity of the entire atmosphere. This project will study and implement such mixing, including the newly described physical phenomenon of wave-induced turbulence, into a variety of models. As a result, wave models and global climate models will be coupled. It is believed that such coupling will enhance our ability to pr ....Wave-Induced Upper-Ocean Mixing.

As a result, wave models and global climate models will be coupled. It is believed that such coupling will enhance our ability to predict the impact of global climate change. As part of the project, predictions of changes to the global wave climate will be developed. Such predictions are important to a nation such as Australia where significant population and economic assets are located close to the coast.Read moreRead less

Summary
Coastal Engineering Research Field Station (CERFS). This project aims to establish a Coastal Engineering Research Field Station (CERFS) with instrument modules for measuring waves, tides, currents, seabed and beach profiles and sediment characteristics. There are critical knowledge gaps in the understanding of coastal processes, including the effects of climate variability and change, and a need to generate long-term data-sets for calibration of coastal models against Australian conditions. The ....Coastal Engineering Research Field Station (CERFS). This project aims to establish a Coastal Engineering Research Field Station (CERFS) with instrument modules for measuring waves, tides, currents, seabed and beach profiles and sediment characteristics. There are critical knowledge gaps in the understanding of coastal processes, including the effects of climate variability and change, and a need to generate long-term data-sets for calibration of coastal models against Australian conditions. The coastal process data obtained will lead to improved models, management strategies and design guidelines improving techniques to address coastal infrastructure design, beach management strategies and impact assessment to meet the challenges of future major coastal development. This will help decision-makers to reduce the risk to coastal communities, coastal ecosystems and maritime operations from extreme storms, climate change, infrastructure development and urbanisation.Read moreRead less

This project aims to develop a comprehensive understanding of the processes responsible for the evolution of ocean swell. It will generate new knowledge in the field by using a combination of newly available satellite data and buoys strategically located along two propagation paths across the Pacific. The expected outcomes will be a unique data set and significant advances in our ability to accurately predict ocean swell. Swell prediction remains one of the major short-comings of ocean wave prediction models. As swell conditions dominate ocean wave climate for 75% of the time, accurate prediction is critical for coastal protection, understanding air-sea interaction and maintaining ship and port operations.Read moreRead less
Development and validation of an innovative wind stress model to obtain robust storm surge forecasts. Storm surges represent a major ocean flood hazard to coastal communities but present models have large errors, which are often dangerously low. Through international collaboration, this project will collect new field data and develop a new storm surge model which will enhance community safety by ensuring accurate forecasts of ocean flood levels.

Under certain conditions a typical sea can becomes bimodal comprising of wind-driven seas and long period swells interacting from two directions. Using a nonlinear model, the occurrence and characteristics of bimodal and bi-directional seastates are quantified.
Low frequency oscillations of a moored offshore structure have profound design influence on the mooring system. A nonlinear response model for a floating vessel in bimodal and bi-directional seastates, will be developed using nonlinear dynamics techniques. The numerical models for the environment and the floating platform will be validated by experiments at the Ocean Basin in Canada.
The project adopts a holistic approach by considering the environment and the moored platform as a complex natural system. With excellent opportunities for technology transfer, the project also benefits from substantial in-kind contributions of the overseas PIs.
