A holistic review is given of the Southern Ocean dynamic system, in the context of the crucial role it plays in the global climate and the profound changes it is experiencing. The review focuses on connections between different components of the Southern Ocean dynamic system…
Antarctic landfast sea ice is an integral component of coastal and nearshore ecosystems, providing bottom-ice habitats that harbour some of the most productive marine microalgal communities on Earth. Ice algal biomass is driven by the spatio-temporal dynamics of snow and sea-ice covers…
Ecosystem dynamics at the northwest Antarctic Peninsula are driven by interactions between physical and biological processes. For example, baleen whale populations are recovering from commercial harvesting against the backdrop of rapid climate change…
The ecosystem approach to fisheries has been discussed since the 1980s. It aims to reduce risks from fisheries to whole, or components of, ecosystems, not just to target species. Precautionary approaches further aim to keep the risk of damage to a low level. Here…
The Southern Hemisphere mid-latitudes, particularly the area around south-eastern Australia and New Zealand, has been suggested as one of the regions where ozone recovery might first be detected…
During simultaneous high-altitude balloon flights from College, Alaska, and Macquarie Island, Australia, on March 5, 1962, substantial fluxes of auroral zone X rays were observed in both hemispheres during magnetic bay activity.
The Global Atmosphere Watch of WMO includes several stations in Antarctica that keep a close eye on the ozone … layer during the ozone hole season. Observations made during the ozone holes from 2003 to 2009 will be compared … to each other and interpreted in light of the meteorological conditions.
One hundred and fifteen sperm whales (97 female, 15 male, 3 unknown sex) were involved in three mass stranding events during the month of February 1998 along the west and northwest coastlines of Tasmania, Australia. Sixty-six of these whales stranded at Ocean Beach, Strahan; 35 at Greens Beach…
