Little is known about Physalia physalis, the bluebottle (BB) in Australia, despite the fact that it is responsible for thousands of stings amongst swimmers every year. In particular, its source, distribution and what causes massive stranding events is unclear. BluebottleWatch is an innovative project between universities and Surf Lifesaving Australia that will shed new light on BB dynamics, pathways, and distribution. In addition to in-situ observations and modelling activities, the project includes laboratory experiments in wave flume and wind/current tank to determine the sensitivity of the trajectories of BBs, in terms of their speed, drifting angle and beaching events in response to winds, waves, and currents. The BBs cannot actively swim, so they are passively advected by the external forcings. Realistic 3D printed plastic models based on scans of stranded BBs are used to test different shapes (left or right-handed, variable sail and body size) and weather and ocean conditions. The objective is to establish empirical relationships between the trajectory of the BBs and the intensity of the wind, current and waves for different morphologies, in order to eventually confirm the theoretical results and explain the variability of observed beachings and fill the knowledge gap on the BBs dynamics.
