Marine heatwaves – understanding our warming oceans

March 4, 2024

As our climate warms, marine heatwaves are becoming more common. This can have detrimental effects for ecosystems and industry alike. Understanding and managing these events is becoming more important.  

Hub researchers will discuss marine heatwaves and their impacts.  One such example is Tasmania’s Huon estuary and how marine heatwaves are contributing to changes in ecosystem health. Presented by hub scientists Neil Holbrook, John Reilly and Julio Salcedo-Castro this will be a look at how marine heatwaves occur, what we can expect in future and how this research can help us adapt. 

Professor Neil Holbrook

Neil Holbrook is Professor of Ocean and Climate Dynamics in the Institute for Marine and Antarctic Studies at the University of Tasmania, Australia. His interests and expertise are in the ocean’s role in climate, ocean and climate variability, extremes, and climate change.

Over the past decade, Neil has contributed to advancing our understanding of marine heatwaves. Neil is an elected Fellow of the Australian Meteorological and Oceanographic Society. He is an investigator in the NESP Climate Systems Hub, and ARC Centres of Excellence for Climate Extremes and 21st Century Weather. He is recognised as a Clarivate highly cited researcher (2021-2023).


Dr Julio Salcedo-Castro

Dr Julio Salcedo-Castro is lecturer of physical oceanography in the Institute for Marine and Antarctic Studies at the University of Tasmania, Australia. His research area is coastal oceanography and estuaries, especially, the response to atmospheric forcing and the impact of extreme events.

He uses modelling, remote sensing and observations to describe coastal oceanographic processes. Julio has studied coastal environments in Canada, Chile, and Brazil. In Australia, Julio worked mapping stressors on the Great Barrier Reef and now is studying the impact of marine heatwaves on the Huon Estuary and D’Entrecasteaux Channel.


Mr John Reilly

John Reilly is a PhD Student at the Institute of Marine and Antarctic Studies within the University of Tasmania. His research is working towards an improved understanding of the drivers contributing to nearshore marine heatwave (MHW) occurrences.

John’s work is focused on developing ultra-high resolution ocean modelling capabilities in order to identify important physical processes that connect the nearshore environment to the offshore ocean dynamics.
