Excessive CO2 emissions isn’t just an atmospheric problem, it’s changing the chemistry of our oceans and impacting ocean life. Join Australian Institute of Marine Science Senior Principal Research Scientist Dr Katharina Fabricius for a special webinar to learn about ocean acidification and how we can help mitigate it.
This webinar is part of National Science Week.

Tagging and tracking the elusive pygmy blue whales of the eastern Indian Ocean is helping us to protect and manage this endangered species, particularly where their migratory route and feeding areas overlap with Australia’s largest oil and gas producing region.
Join Australian Institute of Marine Science Marine Megafauna Ecologist Dr Michele Thums for a special webinar to find out how her team is using acoustics and satellite tracking technology to better understand pygmy blue whale behaviour.
This event is part of National Science Week 2021.

Abstract
Over the past 12 months there have been several maritime accidents in the Indian Ocean that resulted in long-term damage to the marine environment through oil spills and nurdles (plastic pellets) among others. These include oil spills associated with MV Wakashio in Mauritius and MT Diamond in Sri Lanka, respectively and nurdles spill from MV X-Press Pearl in Sri Lanka. In all these cases, real-time predictions (forecasts) of oil and nurdles transport were undertaken at UWA at the request of the Governments of Mauritius and Sri Lanka. MV Wakashio ran aground on a coral reef on the south-east coast of Mauritius on 25 July 2020 and on 6 August broke apart releasing ~900 tonnes of heavy bunker oil that impacted coral reefs and mangroves in the local area. The crude oil carrier MT New Diamond was transporting (~270,000 tonnes of crude oil from Kuwait to India. On 3 September 2020, a fire broke on the ship ~65 kilometres off the east coast of Sri Lanka. After burning intermittently for almost a week, the fire was finally extinguished on 11 September 2020. A diesel oil spill that was ~1 km long was observed during this period. However, the local winds and currents were directed offshore and thus the spill did not interact with the shoreline. The container ship MV X-Press Pearl with 1486 containers on board caught fire on 22 May 2021, engulfed the whole ship and lasted for 13 days. Efforts to move the ship into deeper waters failed and the ship remains on the seabed partly submerged. The cargo included 81 containers were carrying hazardous cargo and included 78 tons of low-density polyethylene (LDPE) pellets or nurdles (~3 billion nurdles). The transport of the nurdles was rapid and within days had spread to onto beaches on the west and southern coasts of Sri Lanka. This was aided by winds and currents associated with the south-west monsoon and remote forcing from a tropical cyclone in the Bay of Bengal. Observations of nurdle beachings corresponded well with the predictions made using the UWA oceanographic models. With time, with the reversing monsoons it is predicted, that the nurdles will spread across the whole of northern Indian Ocean.

Prof Charitha Pattiaratchi is Professor of Coastal Oceanography at the Oceans Graduate School and the Oceans Institute at The University of Western Australia. He leads the IMOS Ocean Glider facility. His research encompass coastal ocean physical processes and their influence on climatic, biological, and geological processes in estuaries, the nearshore and the continental shelf. To date, he has directly supervised more than 285 people (20 doctoral researchers, 75 postgraduate research students and 173 honours/coursework-master’s thesis students). He has published over 500 articles which include 196 in peer-reviewed international journals.

As part of the ‘Coastal Futures – Planning and Adaptation in a Changing Climate’ event series this session will focus on regional responses, local solutions and community resilience in the face of climate change. Hear from our experts about how coastal communities can prepare for and adapt to the challenges brought on by global warming.
AAEE’s 21st Biennial National Conference will attract over 250 dedicated sustainability and educational professionals from across Australia as well as virtually from New Zealand, our overseas neighbours and MOU Partners in the United States, Japan, and Abu Dhabi.
Inspired by moving local examples, resilience theory, future’s thinking and Mandurah’s relaxed waterside lifestyle, Mandjoogoordap: Changing Tides aims to showcase examples of people coming together to create positive change through environmental education, along with innovative, practical and effective tools for change-making.
It’s the place where sustainability and educational professionals can connect and learn, by bringing together academia, industry and leading professionals.
