Understanding the effect of small-scale ocean process on tuna populations – a new tool to forecast tuna distributions for use in fisheries management. The western and central Pacific Ocean supports the world’s largest tuna fishery with catches contributing up to 40 per cent of revenue for many Pacific communities. These nations are dependent on these fisheries for livelihoods and economic development. Continued sustainable management of this valuable resource in the face of rapid population grow ....Understanding the effect of small-scale ocean process on tuna populations – a new tool to forecast tuna distributions for use in fisheries management. The western and central Pacific Ocean supports the world’s largest tuna fishery with catches contributing up to 40 per cent of revenue for many Pacific communities. These nations are dependent on these fisheries for livelihoods and economic development. Continued sustainable management of this valuable resource in the face of rapid population growth and climate variability and change is a challenge. Using observationally derived information of skipjack tuna, the project aims to develop a novel tuna behavioural model. This is intended to be integrated into a state-of-the-art biophysical model at resolutions capable of reproducing critical meso-scale processes, providing projections of tuna distributions that aim to aid in developing sustainable management practices.Read moreRead less

Ocean mixing processes and innovation in oceanographic models. Ocean mixing processes and innovation in oceanographic models: This fellowship project aims to develop new oceanographic tools and thermodynamic variables to support a new generation of accurate ocean models more suitable for the prediction of changes in a warming world. The ocean’s role in the climate system is predominantly to store and to transport heat and carbon dioxide, and the ocean’s ability to do this is sensitive to the str ....Ocean mixing processes and innovation in oceanographic models. Ocean mixing processes and innovation in oceanographic models: This fellowship project aims to develop new oceanographic tools and thermodynamic variables to support a new generation of accurate ocean models more suitable for the prediction of changes in a warming world. The ocean’s role in the climate system is predominantly to store and to transport heat and carbon dioxide, and the ocean’s ability to do this is sensitive to the strength of mixing processes, which are quite uncertain. This project hopes to distinguish the vital role of vertical mixing from that of horizontal mixing by (i) developing algorithms to construct neutral density surfaces in climate models, (ii) formulating new inverse techniques to deduce the amount of vertical mixing in various ocean regions, and (iii) incorporating new approaches to ocean mixing processes and thermodynamics into ocean models.Read moreRead less
What caused abrupt climate change events in the past and what can they tell us about the future? This project will improve our understanding of abrupt climate change in the past, present and future. It will dramatically enhance Australia's capacity to use climate models to assess the probability and associated consequences of abrupt climate change in the future.

Summary
Ingredients of the eddy soup in Southern Ocean dynamics: processes, climate impacts and parameterisation. This project aims to understand jet-topography-eddy interactions in the Southern Ocean, and to apply that understanding to improving the representation of ocean physics in models. It will provide the underpinning science needed to increase confidence in climate predictions that will allow Australia to more effectively respond to climate change.

Decadal climate variability: Mechanisms, interactions and effects. This project aims to study the processes underlying decadal climate variability, through increasingly complex models, underpinned by observations. Climate variations on time scales of years, decades and longer affect Australia, with potentially devastating effects on agriculture, water supply, bushfires and health. Improved climate prediction on decadal time scales is urgently needed, but limited understanding of the system’s nat ....Decadal climate variability: Mechanisms, interactions and effects. This project aims to study the processes underlying decadal climate variability, through increasingly complex models, underpinned by observations. Climate variations on time scales of years, decades and longer affect Australia, with potentially devastating effects on agriculture, water supply, bushfires and health. Improved climate prediction on decadal time scales is urgently needed, but limited understanding of the system’s natural variability hampers progress. This knowledge will reduce uncertainty in near term climate projections, allowing more informed decision making about adaptation on the regional scale, particularly for sectors such as agriculture, health, water and ecosystem management (including bushfire control).Read moreRead less
