Over 200 members of the general public attended the sold out event “Showcasing Victoria’s Marine Science” at Museum Victoria last week. This event aimed to showcase some of the most cutting edge research being conducted by Victorian marine scientists, and was hosted by the Australian Marine Sciences Association Victoria branch and Museum Victoria.
We handpicked six marine scientists to share their diverse and inspiring research stories with the general public. Here are stories from three of our presenters:
Dr Peter Macreadie, from the University of Technology Sydney, shared his bright ideas for blue carbon: “Reducing carbon emissions is an important approach to tackling climate change, but too frequently we forget that we have another weapon up our sleeves: ‘biosequestration’, which is the natural process of using plants, trees, and soils to capture and store carbon. We have recently discovered that coastal vegetated habitats – seagrasses, saltmarshes and mangroves – are among the most powerful carbon sink on the planet. They can bury carbon at a rate 40-times faster than forests and have the ability to keep buried carbon locked away for millennial time scales”.
Dr Macreadie is working with scientists at Deakin University and their research has shown that human-induced changes in the coastal zone has caused a 100-fold weakening in the ability of coastal sediments to store carbon and thereby help mitigate climate change. It’s not all bad news though, Peter says that “Australia’s land is girt by sea and abounds in blue carbon sinks, which puts us in a prime position to capitalise on nature’s ability to help reset our planet’s thermostat”.
Dr Alecia Bellgrove, from Deakin University in Warnambool, shared her research on seaweed superfoods: “Seaweed production via aquaculture has doubled in the past 10 years and now accounts for a total annual harvest of 23.8 million tonnes valued at over US$6 billion globally. There is currently no commercial aquaculture of Australian seaweeds, however we are receiving increasing interest from international importers for sources of high quality Australian Made seaweeds that are perceived as clean and pure, particularly in Asian markets”.
Dr Bellgrove believes that the opportunity for a new, sustainable and vibrant Australian seaweed industry is dawning. Her research group have begun to explore the unique Australian marine flora for potential new edible seaweed products for both domestic and international markets. Their palatability tests and preliminary nutritional analyses suggest that Aussie seaweeds fair really well against existing commercial products.
Dr Kate Charlton-Robb, from the Australian Marine Mammal Conservation Foundation, shared her dolphin discovery research: “In a time when we are losing species at an alarming rate, it is a rare event to discover a new species, let alone a dolphin that has been living right under our noses. The Burrunan dolphin, Tursiops australis, was formally described and named in 2011, and has two of the only known resident populations here in Victoria”.
Dr Charlton-Robb explained the bitter-sweet experience of the excitement of discovering the Burrunan dolphin, whilst officially listing this dolphin as threatened. “With an effective population size of less than 100 dolphins in each of the Port Phillip Bay and Gippsland Lakes resident populations, there is considerable concerns around the conservation of this species” Kate said. Kate’s research team are currently conducting applied research to further protect the Burrunan dolphin, by incorporating population and distribution assessments, conservation genetics and identifying areas of significance for this iconic species.
Our other three speakers shared their diverse and inspiring research stories with the general public: Tim Allen shared his perspective on the immense value of scientific research in Victorian marine conservation efforts; Dr Tim O’Hara inspired the audience about the amazing advances in deep sea biodiversity research at Museum Victoria; and, Associate Professor Jan Strugnell shared her southern ocean research that has revealed how dramatic ocean events of the past have left their legacy in the genes of an Antarctic octopus.
This event has shown that Victorian marine scientists are producing high impact scientific knowledge with great environmental and economic value, and the public interest shown in this event is testament to its enormous social value.
Given the great success of this public event, AMSA Victoria are already planning another public event that will coincide with the national AMSA conference in Geelong this July. On Monday July 6th 2015, we will be hosting a Q&A style public event, where we will joined by a panel of leading Australian marine scientists who will discuss some of Australia’s major marine issues, and answer questions posed by the audience. From super trawlers to marine parks, it promises to be an evening of lively debate. So start thinking of some curly questions and keep an eye on our conference events webpage for more details.
