Aim … To map presence, absence and ignorance of Antarctic seabird breeding occupancy at the spatial resolution of ice-free habitat sites to identify knowledge gaps and inform management and conservation. Location … East Antarctica between longitudes 30°?E and 150°?E.
Microbial communities in Antarctic marine sponges have distinct taxonomic and functional profiles due to low temperatures, seasonal days and nights, and geographic isolation. These sponge holobionts contribute to nutrient cycling, structural habitat formation, and benthic ecosystem resilience.
Since 2001, hundreds of thousands of hours of underwater acoustic recordings have been made throughout the Southern Ocean south of 60° S. Detailed analysis of the occurrence of marine mammal sounds in these circumpolar recordings could provide novel insights into their ecology…
Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore…
The Southern Ocean Research Partnership (IWC-SORP) is a multi-lateral, non-lethal scientific research programme established in 2009 to improve the coordinated and cooperative delivery of science to the IWC. There are 13 Partners: Argentina, Australia, Belgium, Brazil, Chile, France, Germany, Italy…
This report to the Seventh Meeting of the Parties has been prepared by the Advisory Committee Chair and Vice-chair with the assistance of the Agreement's Secretariat under Article IX 6 (e).
This report to the Seventh Meeting of the Parties has been drafted as a document in progress for the Advisory Committee by the Chair and Vice-chair with the assistance of the Agreement's Secretariat.
As the ATCM was sadly cancelled in 2020, in light of the global Covid-19 pandemic, ATCMXLIII in 2021 is the first meeting of the Parties since the publication of the Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The SROCC…
The parameterization of gravity waves in the NCAR Whole Atmosphere Community Climate Model (WACCM) includes orographic, convective, and frontal sources. Even with these, the model simulates temperatures in the Antarctic lower stratosphere during winter and spring that are much lower than observed.
Changes in buoyancy during an animal’s time at sea are a powerful tool for inferring … spatial and temporal foraging success. Buoyancy can be difficult to measure, but in some species of … seal, drift components of dives can be used.
Two terrestrial Crustacea, Puhuruhuru patersoni (Amphipoda: Talitridae) and Styloniscus otakensis … (Isopoda: Styloniscidae), were discovered on sub-Antarctic Macquarie Island in 1991 and 1992, respectively. Each … species was identified as having been described, and previously only known…
Monitoring CO2 isotopes at Cape Grim commenced in 1976 (Goodman, 1980), using CO2 extracted from the air and returned to Aspendale for mass spectrometer analysis. The objective was to distinguish between terrestrial (including biosphere exchanges, deforestation and fossil fuel emissions)…
Apparent drift motion of polar cap arcs may be indicative of plasma convection processes in the ionospheric plasma. The dynamics of a number of individual polar cap events observed by a dual wavelength all-sky imager at Scott Base have been analysed in detail. The imager…
