Dr Jak McCarroll from the School of Geosciences offers five pointers for swimmers this summer.
Rips generally occur on ocean beaches where waves are big enough to go surfing, usually at the more exposed end of the beach.
Dark patches of water, wavy, snaky shorelines, outward bending wave crests all indicate rips may be present. Their flow behaviour can change every 5-10 minutes.
There’s no silver bullet to escaping rip currents, which are hazardous and unpredictable. People who are not experienced surfers or bodysurfers should always swim between the flags, which are positioned to avoid rips.
These rip escape methods include staying afloat, or swimming parallel to shore – before finding one that works for the rip you’re in. Our research showed this can take up to 10 minutes so you should conserve energy, swimming at a gradual pace; escaping a rip is like a game of chess.
Panicking and swimming as fast as you can into the rip is a good way to become exhausted and drown. However our research has shown that an early controlled attempt to swim onshore (towards the shore) is often successful. If you attempt to escape a rip by swimming onshore, do it early and if it doesn’t succeed within 30 seconds of steady paced swimming, STOP and try something else.
Dr McCarroll’s findings on how to best escape rips were recently published in Geomorphology and Natural Hazards.
Three small Australian cube-sized satellites will be launched from the International Space Station to research new regions that could impact technology used on Earth, with the University of Sydney leading development of one of the CubeSats, undergoing testing in Canberra this week.
Sudden cardiac death claims the lives of 2-3 young Australians every week.
Unveiled this week, the new flight planning system is the result of a world-first, four-year project conducted at the University’s Australian Centre for Field Robotics (ACFR). The team comprising four aeronautical research fellows, 3 PhD candidates and 10 software engineers worked on designing new system models.
The University of Sydney has welcomed the NSW Government's $25 million pledge to create the Sydney School of Entrepreneurship as a new collaborative venture in the higher education sector.
With Australia’s farming future looking increasingly reliant on automated technologies, such as low-cost robotics, the industry’s vision should include more support for agri-technology start-ups, retraining growers and agronomists for a digital age, and introducing rural kids to hands-on robotics.
Despite demand from overseas markets such as China, Australia’s milk wars illustrate the difficulty of taking a low-cost commodity approach to competition. Farmers need to embrace digital disruption, promoting our renowned clean, green produce by using tools that are increasingly available to detail the journey from behind the farm gate to the consumer.
MadMaker is the brainchild of electrical and information technologies engineer Dr Abelardo Pardo, a specialist in technology-based learning. It was designed to inspire students who may not have previously considered a future career in engineering, technology or science-related fields.
University of Sydney alumnus Dr Martin Seneviratne has been named the 2017 Roden Cutler NSW John Monash Scholar. The award will see Dr Seneviratne head to Stanford University to continue his ground-breaking work into clinical informatics.
The festive season can be hazardous for companion animals so we need to take precautions to keep them healthy and happy. Dr Anne Fawcett from the Faculty of Veterinary Science tells us the major things to be aware of this summer.
A team of University of Sydney students gained second spot against teams of researchers in the AgData Challenge hackathon, with a PhD student also leading the winning CSIRO team.
