Sea ice can be interspersed vertically with both permeable and impermeable layers. These features can be smaller than a few centimetres but are important for understanding biogeochemical cycles in sea ice. Traditionally…
A southern right whale (Eubalaena australis) was found dead, stranded on a remote rock platform at Torndirrup, Western Australia, on 20 September 2022.
Southern right whales (Eubalaena australis) migrate between Austral-winter calving and socialising grounds to offshore mid- to high latitude Austral-summer feeding grounds. In Australasia…
Genetic diversity is fundamental to biological diversity, vital for species’ health and adaptation to environmental change. Under the recently adopted Kunming-Montreal Global Biodiversity Framework (GBF)…
Groundwater response to climate variations is often pivotal to managing groundwater sustainably. However, this relationship is rarely explicitly examined because of the complexity of surface to subsurface processes and the diverse impacts of multiple drivers…
This Summary for Policymakers uses information and infographics from the research articles, updated with other more recent research articles, to provide the following information: 1.
Background … Satellite tags were deployed on 50 east Australian humpback whales (breeding stock E1) between 2008 and 2010 on their southward migration, northward migration and feeding grounds in order to identify and describe migratory pathways, feeding grounds and possible calving areas.
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.
During three surveys in the austral summers of 2013, 2015, 2019, data on Antarctic blue whale blow rates, dive times, swim speeds, and broadscale movements were collected using video photogrammetric tracking and intra-voyage photo-identification. A total of 24.
Missing gravity wave drag near 60 degrees south has been proposed as the cause of the common cold bias in modelled southern polar stratospheric temperatures [McLandress et al. 2012]. Potential gravity wave momentum sources around those latitudes, such as jets…
Sewage discharge into near-shore marine ecosystems is one of the most common forms of contamination that occurs in Antarctica today, and is likely to impact on the biota living in these habitats. In this study the morphological responses of four species of Abatus heart urchins (A. philippii, A.
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…
Arctic ecosystems and global climate are closely related. This paper studies the distributions and the coupling relationship between Chlorophyll a (Chl a) and aerosol optical thickness (AOD) in Greenland Sea (10 degrees W - 10 degrees E, 70 degrees N - 85 degrees N)…
The Diego Ramírez Archipelago, Chile, is the southernmost albatross breeding ground in the world and holds … globally important numbers of Black-browed (Thalassarche melanophrys) and Grey-headed (T. chrysostoma) Albatrosses. A census in the Diego Ramírez Archipelago has been attempted only once…
Space weather forecasting is a very important tool for the space situational awareness to the space objects, the space environment and related threats and risks for manned and non-manned spacecrafts. The global network of ground based multi-directional detectors (GMDN)…
