Passive and active swimmers in complex flows. Strong interest in the motion of active swimmers in turbulent flows is triggered by problems such as sea search and rescue algorithms or diffusion of microorganisms in aquatic environments. For example, the patchiness in the distribution of phytoplankton can be related to the exposure of the microorganisms to turbulent flows.

Strong interest in the motion of active swimmers in turbulent flows is triggered by problems such as sea search and rescue algorithms or diffusion of microorganisms in aquatic environments. For example, the patchiness in the distribution of phytoplankton can be related to the exposure of the microorganisms to turbulent flows. Recent progress in laboratory modelling of turbulence and the fabrication of artificial swimmers using Janus particles makes it possible to study these processes in the laboratory. This project is intended to undertake the first such study. The project is expected to help understand the impact of particle motility on turbulent dispersion.Read moreRead less
Extreme wave events on the water surface. Giant waves observed in the ocean present a catastrophic threat to ships and offshore structures. Rogue waves in optical fibres, on the other hand, may help developing powerful light sources for long-distance telecommunications. This study of capillary rogue waves on the water surface will help to predict and control the probability of extreme waves.

Summary
Wind profiler network for planetary boundary layer research. Understanding winds in the lower atmosphere is of great fundamental and practical importance. This new wind monitoring network will help Australian scientists to better predict propagation of tropical cyclones, to improve the efficiency of wind energy production, and to better understand atmosphere-ocean interactions affecting weather and climate.
