The 7th International Zooplankton Production Symposium was held in Hobart, Australia in March, 2024 with the theme 'New Horizons', chosen to reflect the current perception that oceans are now experiencing greater human impacts than ever before, and to explore how zooplankton are impacted.
Plankton, a diverse group of aquatic organisms, make Earth livable, regulate aquatic life, and provide benefits to human societies such as access to clean water, food security, and well-being. They also support economies and inspire biotechnological innovations.
Deep chlorophyll maxima (DCMs) have long been studied in the northern hemisphere but have received less attention in the Southern Ocean. Their contribution to phytoplankton biomass and net primary productivity (NPP) is poorly resolved. Recently…
The passive sinking flux of particles, termed the biological gravitational pump (BGP), is an important component of the ocean's biological carbon pump. In addition, carbon-rich particles are actively injected to depth through the diel vertical migration (DVM)…
Around 176500 whales were killed in the sub-Antarctic waters off South Georgia (South Atlantic) between 1904 and 1965. In recent decades, whales have once again become summer visitors, with the southern right whale (SRW) the most commonly reported species until 2011. Here…
Accidental fuel spills associated with the storage, transfer, and use of diesel fuel for power generation have occurred on sub-Antarctic Macquarie Island since the establishment of the island's research station in 1948.
Body-size relationships between predators and prey exhibit remarkable diversity. However, the assumption that predators typically consume proportionally smaller prey often underlies size-dependent predation in ecosystem models. In reality…
Fabrics, also known as textures or crystallographic preferred orientations, reveal information about the deformation history of the flow of polycrystalline materials, including glacial ice, olivine in the mantle, and feldspar and quartz in the crust.
To ensure effective restoration and environmental protection of fuel spill sites on Macquarie Island that have undergone remediation, the Australian Antarctic Division has developed site-specific Environmental Quality Guidelines and Remediation Targets.
Terrestrial fuel spills in Antarctica commonly occur on ice-free land around research stations as the result of human activities. Successful clean-up of spills not only requires appropriate remediation strategies and technologies that are effective in cold climates…
Several fuel spills have occurred near Australia’s Antarctic stations, associated with the use of SAB diesel for power generation. This has resulted in significant petroleum hydrocarbon contamination in soils.
Terrestrial fuel spills in Antarctica commonly occur on ice?free land around research stations as the result of human activities. Successful spill clean?ups require appropriate targets that confirm contaminated sites are no longer likely to pose environmental risk following remediation.
The Southern Ocean islands are some of the most isolated landmasses in the world. Few of the islands support permanent human settlements or land based industries and as such they remain as some of the most uninvaded landscapes globally.
