Overview of thesis

Marine heatwaves (MHWs) are reshaping ocean ecosystems and threatening global fisheries. With ocean temperatures projected to rise significantly above average by 2100, understanding species responses to thermal extremes is critical, yet current knowledge remains fragmented across isolated studies. My PhD research examines both mobile and sedentary marine species through comprehensive response models (statistical methods and machine learning) for key commercial species, including Spanish Mackerel (Scomberomorus commerson), Greenlip (Haliotis laevigata) and Brownlip (Haliotis conicopora) abalone in Western Australia (WA). The study will also undertake a trophic assessment of MHW impacts in the Shark Bay region using Ecopath with Ecosim, along with scenario-based modelling to predict species- and ecosystem-level responses to MHWs.

This research forms part of the JTSI/UN Ocean Decade project involving several universities and institutions in WA, with DPIRD as a close collaborator. The work will provide fisheries managers in WA and globally with species-specific response plans and early warning systems for MHW-related disruptions.
