MICROSCALE PLANKTON AND PARTICLE DYNAMICS: COMPARING AND CONTRASTING AUSTRALIAN AND INTERNATIONAL SEAS. Microscopic phytoplankton are the basis of ocean ecosystems, but most predictions and measurements focus on processes that occur over kilometres. Our recent work shows that definite and regular submetre seascape topography exists. This grant will test the extent to which this seascape topography is the fundamental organisational unit of marine ecosystems and the extent to which it characteris ....MICROSCALE PLANKTON AND PARTICLE DYNAMICS: COMPARING AND CONTRASTING AUSTRALIAN AND INTERNATIONAL SEAS. Microscopic phytoplankton are the basis of ocean ecosystems, but most predictions and measurements focus on processes that occur over kilometres. Our recent work shows that definite and regular submetre seascape topography exists. This grant will test the extent to which this seascape topography is the fundamental organisational unit of marine ecosystems and the extent to which it characterises Australian coastal waters and open ocean water masses. This research takes a leadership role in defining and advancing our understanding of how marine ecosystems function. The project will bring over $200 million of Japanese infrastructure to Australia for 3 years.Read moreRead less
Improved management of coastal plankton systems by ancient DNA technology. This project aims to assemble comprehensive long term Australian plankton records spanning 50 to 1000 years, by applying ancient DNA technology to dated sediment depth cores. Long-term data for Australian coastal and estuarine waters are sparse, so cannot be used for management of fisheries, tourism or urban development. Long-term records are essential to understand how disruptive algal and jellyfish blooms, introduced sp ....Improved management of coastal plankton systems by ancient DNA technology. This project aims to assemble comprehensive long term Australian plankton records spanning 50 to 1000 years, by applying ancient DNA technology to dated sediment depth cores. Long-term data for Australian coastal and estuarine waters are sparse, so cannot be used for management of fisheries, tourism or urban development. Long-term records are essential to understand how disruptive algal and jellyfish blooms, introduced species and increased human use of coastal resources affect dynamic plankton ecosystems. This project’s findings are expected to explore cyclical patterns, define range expansions and understand and manage how dynamic coastal ecosystems respond to multistressor anthropogenic change. Findings will improve understanding of how dynamic marine environments retain their biodiversity values and critical ecological functions.Read moreRead less
Microbial Oceanography: Community Heterogeneity Fuelled by Environmental Variability. The ocean is a crucial resource to Australia. This work will open a new area of research within Australian habitats, which will improve our understanding of how the base of the ocean food web functions, and build a new perspective from which to look at the microscopic plankton that influence fisheries yield and species invasions. Appreciating how microbial communities respond to environmental perturbations will ....Microbial Oceanography: Community Heterogeneity Fuelled by Environmental Variability. The ocean is a crucial resource to Australia. This work will open a new area of research within Australian habitats, which will improve our understanding of how the base of the ocean food web functions, and build a new perspective from which to look at the microscopic plankton that influence fisheries yield and species invasions. Appreciating how microbial communities respond to environmental perturbations will provide an improved vantage-point to predict future changes to the Australian marine environment. Leading international scientists will provide conceptual and technical expertise in an Australian based project, applying novel analytical tools not currently employed within oceanographic surveys within Australian waters.Read moreRead less
Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidenc ....Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidence of these keystones’ cellular level biogeochemical and metabolic capacity. Ultimately, this knowledge is expected to predict the resilience of ocean ecosystems and their response to change. The capacity to predict their dynamics will help provide investment clarity and increase healthy outcomes from activities involving human-ocean interactions such as recreation, food production and tourism.Read moreRead less
Physical and Ecological Structure at the Base of Ocean Food Webs. The coastal ocean is a crucial resource to Australia. In founding a research area on coastal food web function we provide international scientific leadership, train scientists in a cutting edge area, and lay the foundation for improved management of fisheries, aquaculture and species invasions. This work boosts Australia's participation in the International Polar Year, and knowledge about Antarctic Territorial waters. Infrastructu ....Physical and Ecological Structure at the Base of Ocean Food Webs. The coastal ocean is a crucial resource to Australia. In founding a research area on coastal food web function we provide international scientific leadership, train scientists in a cutting edge area, and lay the foundation for improved management of fisheries, aquaculture and species invasions. This work boosts Australia's participation in the International Polar Year, and knowledge about Antarctic Territorial waters. Infrastructure benefit comes from the French government paying for an outstanding French scientist to come to Australia 6 months/yr for 5 yrs. This grant acts as the base for larger projects that import EU and American funds.Read moreRead less
