Ningaloo Marine Park is part of the National Representative System of Marine Protected Areas. Coral reefs are in a state of decline worldwide, yet Ningaloo Reef has remained in a relatively pristine state. However, its close proximity to land makes it particularly vulnerable to human activities, which are forecast to significantly grow in the near future. Results from this project will advance our ability to predict circulation on reefs and other similar coastal systems. This will provide insight into various ecological processes that are linked to hydrodynamics (e.g. recruitment), and will provide a foundation for conducting risk analysis of processes that threaten the integrity of nearshore environments (e.g. contaminant spills).Read moreRead less
Ocean-reef interactions as drivers of continental shelf productivity in a changing climate. Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will p ....Ocean-reef interactions as drivers of continental shelf productivity in a changing climate. Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will provide key information on the oceanographic mechanisms supporting Australia's coastal systems, linking nutrient supply, physical drivers and climate. By linking all these factors we will both assist in determining appropriate ecosystem management, and provide a knowledge base to support adaptation to future changes in Australia's climate.Read moreRead less
Robotic investigation of water optical properties in the Southern Ocean. The project aims to improve our understanding of light–matter interactions in the waters of the Southern Ocean (SO), in particular the role of phytoplankton and associated material of biological origin. Phytoplankton are the energy source for the food web and a critical component of carbon cycling in the SO. However, their dynamics in the SO cannot be quantified using satellite observations because bio-optical data processi ....Robotic investigation of water optical properties in the Southern Ocean. The project aims to improve our understanding of light–matter interactions in the waters of the Southern Ocean (SO), in particular the role of phytoplankton and associated material of biological origin. Phytoplankton are the energy source for the food web and a critical component of carbon cycling in the SO. However, their dynamics in the SO cannot be quantified using satellite observations because bio-optical data processing algorithms perform poorly due to a lack of field data. This project seeks to remedy this by improving understanding of SO bio-optics, and by providing novel algorithms of known uncertainty, based on in situ data.Read moreRead less

This project aims to create a floating, mobile fisheries and oceanographic observing system for Eastern Australia. Australian oceanographic and fisheries research has been hampered by the lack of appropriately sized and equipped research vessels required to investigate continental shelf waters and beyond. The automated floating facility will provide data to support ongoing ARC-funded research programs in marine biogeochemistry, climate change, ocean acidification, coastal hydrology, biological oceanography, active acoustics, and fisheries resources and technology in the continental shelf and beyond. The expected outcome will bridge a major gap in fisheries and oceanographic research capacity to make observations in a critical region of the Australian marine estate and provide a stronger scientific basis for early detection of changes in seawater chemistry, biology and fisheries in priority waters experiencing rapid change.Read moreRead less
Why ocean deserts matter: Phytoplankton productivity in oligotrophic waters. This project aims to revisit the role of ocean deserts in the global ocean primary production. Because of their extent, these areas are paradoxically responsible for about half the global ocean carbon fixation. The project will use a unique combination of optical and biogeochemical data from a research voyage in the Indian Ocean, biogeochemical models and satellite observations, expecting to generate new knowledge on th ....Why ocean deserts matter: Phytoplankton productivity in oligotrophic waters. This project aims to revisit the role of ocean deserts in the global ocean primary production. Because of their extent, these areas are paradoxically responsible for about half the global ocean carbon fixation. The project will use a unique combination of optical and biogeochemical data from a research voyage in the Indian Ocean, biogeochemical models and satellite observations, expecting to generate new knowledge on the link between biogeochemical and optical quantities accessible to satellite remote sensing. Expected outcomes are improved estimates of phytoplankton carbon biomass and productivity, in particular in the Indian Ocean. A key benefit will be an improved end-user relevance of satellite monitoring of Australia’s oceans.Read moreRead less

The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the development of groundwater resources, the relative dependency of ecosystems on groundwater versus soil and surface water, and an assessment of the likely impacts of altered hydrology, especially dewatering and salinisation, on ecosystems. In addition, they will also be used to extend our knowledge of climate variability in the recent past and increase understanding of critical marine resources.Read moreRead less

The marine productivity buoy: a multi-parametric underwater profiler:
The marine productivity buoy is an innovative multi-parametric moored underwater profiler that would provide key information on phytoplankton primary productivity (PP), phytoplankton blooms, and water quality in coastal waters around Australia. The aim is to better understand changes in phytoplankton PP and abundance by synergistically using observations from the new facility made several times a day from the surface to the seafloor, and spatially extended surface observations from Earth-orbiting ocean colour satellites. Anticipated outcomes are more accurate phytoplankton PP estimates and water quality parameters in Australian coastal waters in support to research and to monitoring of these critical environments.Read moreRead less
Impact of global stressors on the metabolic balance of the coastal Indian Ocean. The pelagic community metabolic balance characterises the role of ocean biota as a sink or source of carbon dioxide. No estimates of net community metabolism are available for the Indian Ocean, which is a major gap in our knowledge.

No estimates of net community metabolism are available for the Indian Ocean, which is a major gap in our knowledge. Key environmental stressors, UVB radiation and warming (particularly heat wave events) have the potential to impact on pelagic community metabolism, especially along the Western Australian coast. This project addresses the lack of estimates of plankton metabolic balance in the coastal Indian Ocean and assess how multiple concurrent stressors can affect pelagic metabolism in the coastal Indian Ocean in a context of global change.Read moreRead less
