LUNCHBOX SCIENCE WITH DR RACHEL GRAY
Date: Wednesday 15 July 2020 Time: 12pm – 12:45pm
In July 2019, a research team from the Sydney School of Veterinary Science embarked on a novel treatment intervention in the endangered Australian sea lion on Kangaroo Island. Hookworm infection affects 100% of pups, causing significant disease and contributes to high pup deaths. The study aimed to eliminate hookworm from a subset of pups and monitor their health and growth. This Lunchbox Science webinar will discuss the project and its outcomes.

Marine Studies Institute marks World Oceans Day
As one of the largest marine research and education centres in Australia, the Marine Studies Institute conducts marine science across a huge range of areas. This world oceans day the university of Sydney highlighted some of the important research done at MSI. Read the article here.

My fieldwork is based in Jervis Bay on the south coast of NSW. Jervis Bay is a resting ground for mother-calf humpback whale groups during their southern migration from breeding grounds on the Great Barrier Reef to feeding grounds in Antarctica. For the last two years (2018/2019) I have spent six week blocks down in Jervis Bay during September/October recording the numbers and movements of whales in the Bay…
SAMPLING WITH AUSMAP
Last week we volunteered with AUSMAP to help them do a sampling of microplastics on Airport Beach next to Cooks River mouth. The amount of plastics washed up on the beach was astounding!
Among the macro plastics we found large amounts of plastic bags, containers, straws and bottles, while the microplastics included plastic pellets (nurdles) and all sorts of broken up plastics. We suspect most of these plastics originate from land and have been washed out to sea through the Cooks River.

New study raises concern over rapidly warming estuaries
The study, led by Dr Elliot Scanes from the University of Sydney, found estuaries in the south-east of Australia are warming at twice the rate of oceans and the atmosphere. The data collected from 166 estuaries for 12 years found an average yearly temperature rise of 0.2 degrees. The data also revealed an increase in acidification of estuary systems, the average pH increased by 0.09 units yearly.

MSI is investigating the distribution of microplastics on Australian beaches on a spatial and temporal scale. The aim is to identify hotspots for microplastic sedimentation in beach sand by looking at abundances of microplastics in different locations.
Our day to day activities have environmental consequences, be them small or large, good or bad. At MSI we are seeking to quantify how daily activities from brushing your teeth, to getting to work, and eating dinner impact our environment. We hope to find everyday solutions to combat our personal carbon emissions. Together we can tread lightly on this earth.
Mercury poisoning from fish has long been a concern for the world ever since the Minamata disaster in Japan. At MSI we have created a database of research into mercury levels in fish and marine sediment across the world. It is hoped that this database can help us to compare mercury levels across the world and between species. The interactive map below shows the locations of all of the Mercury research included in our database
