Understanding how ecological, environmental and geographic features influence population genetic patterns provides crucial insights into a species' evolutionary history, as well as their vulnerability or resilience under climate change. In the Southern Ocean…
Human influence on Antarctic marine ecosystems is a growing concern, despite limited … information being available. This study investigated the coastal meiofauna and environmental … parameters of 10 locations, 4 of which served as reference points (OB1, OB2, OB3, and McGrady)…
Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been … developed to evaluate population genetic trends without necessarily collecting new genetic data. Such "genetic diversity … indicators" enable rapid…
Programs for the measurement of atmospheric carbon dioxide using infra-red gas analysis techniques, have now been conducted by CSIRO in the Australian/Antarctic region of the Southern Hemisphere for over fifty years. In this report…
Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed…
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)…
The marine-based West Antarctic Ice Sheet (WAIS) is considered vulnerable to irreversible collapse under future climate trajectories, and its tipping point may lie within the mitigated warming scenarios of 1.5° to 2°C of the United Nations Paris Agreement.
Dense, cold waters formed on Antarctic continental shelves descend along the Antarctic continental margin, where they mix with other Southern Ocean waters to form Antarctic Bottom Water (AABW). AABW then spreads into the deepest parts of all major ocean basins…
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)…
We use complementary observations from the prototype Global Muon Detector Network (GMDN) and the Advanced Composition Explorer satellite to identify precursors of geomagnetic storm events. The GMDN was completed in March 2006 with the installation of the Kuwait detector…
We analyse the precursor of a Forbush decrease (FD) observed with the Global Muon Detector Network on 2006 December 14. An intense geomagnetic storm was also recorded during this FD with the peak Kp index of 8+.

The Global Muon Detector Network (GMDN) was … completed by installing a multi-directional cosmic-ray muon … hodoscope in Kuwait University in March 2006. The GMDN is … currently consisting of four multi-directional muon detectors … located at Nagoya (Japan), Hobart (Australia), Sao Martinho …
We have developed a method for determining interplanetary coronal mass ejection … (ICME) geometry from galactic cosmic ray data recorded by the ground-based muon … detector network. The cosmic ray density depression inside the ICME, which is associated … with a Forbush decrease…
A multi-directional telescope for detection of high-energy galactic cosmic rays (GCRs) - muons … was installed in 2001, through an international cooperation between Brazil, Japan and USA, and … operated since then at the Southern Space Observatory - SSO/CRS/INPE - MCT, (29S, 53W)…
We present for the first time hourly variations of the spatial density gradient of 50 GeV cosmic rays within a sample … solar rotation period in 2006. By inversely solving the diffusive flux equation, including the drift…
We investigated the unidirectional fractional density gradient in GSE-z (GzU) of Galactic Cosmic Ray (GCR) by using the data obtained by the Muon detector network. The analysis period is from 1994 to 2005. We found that the yearly averaged GzU show temporal variations.
