Coastal Resilience: Shifting Sands and Battered Beaches

Our sea levels are rising. Understanding the dynamics of the beach envelope and its overlap with human infrastructure is fundamental for effective coastal management. Dr David Kennedy studies the dynamic adaptation of beaches in the past to inform how we can manage them into the future. While NSW beaches have been studied for decades, but we are only just starting to understand the behaviours of Victoria’s beaches and their underlying geology.

Young Scientist Research Prizes 2020

Every year, final year PhD candidates present their doctoral studies to the Royal Society of Victoria, competing for four Prizes that recognise excellence in Victoria’s young scientists. Eight finalists present under the four categories: Biological Sciences, Biomedical & Health Sciences, Earth Sciences, and Physical Sciences. While the format of delivery was different this year, participants rose to the challenge to deliver engaging and informative videos for National Science Week. From chicken sexing to neutron stars, all finalists’ presentations are summarised here, with links to their video presentations and the full proceedings as broadcast on the night via Facebook Live.

From Meteorites to Meteorology – Diverse Victorian Science in the Latest Proceedings

The latest edition of the Proceedings of the Royal Society of Victoria is now online, featuring a new species of calcareous sponge discovered in Geelong, a spectacular new H5 meteorite in Maryborough, an account of Indigenous meteorological knowledge using stellar scintillation, a reclassification of fossil graptolites from the early Bendigonian, a case for regulated investment in a resilient electricity network, an account of the Bureau of Meteorology’s new extreme heatwave event forecasting service, and a discussion on whether a similar service might be required for cold extremes.

From Past to Future: Stories of a Geoscientist

Associate Professor Stephen Gallagher has spent months at sea over the past several years, drilling into the past to obtain a record of Australian geological history. The expedition set out to recover a 5-million-year record of the Australian climate – and surpassed their expectations by uncovering 50 million years. Gallagher was pleasantly surprised at the gems of information discovered on changes to aridity, sea levels, and monsoon cycles that the core samples revealed.

Australia’s earliest humans? The case for Moyjil

The latest, special issue of the Royal Society of Victoria’s Proceedings concerns itself in detail with a ten-year research program led by a multidisciplinary team from four Victorian universities. The subject is an unusual deposit of shells and burnt stones at Warrnambool, in western Victoria. The site, originally recognised by the late Edmund Gill, is at the mouth of the Hopkins River, known as “Moyjil” by Traditional Owners. It contains the remains of shellfish, crabs and fish in a cemented sand, together with charcoal, blackened stones and features which resemble fireplaces. The dating of the shells, burnt stones and surrounding cemented sands by a variety of methods has established that the deposit was formed about 120,000 years ago, roughly twice the presently accepted age of arrival of people on the Australian continent based on archaeological evidence.
