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…
Here we validate the Surface Water and Ocean Topography (SWOT) satellite mission sea surface height (SSH) products using an array of nine GNSS buoys at the long-term altimetry validation facility in Bass Strait. As a groundbreaking swath altimetry mission…
Blue whale and their subspecies is an endangered whale species that needs to be conserved by protecting their important habitat and migration corridor. Research about designing and modelling blue whale habitat for marine protected area has been done many times. However…
1. Marine invasive species can cause irreparable change in new environments, though not all non-native … species inevitably cause negative impacts to recipient … ecosystems.
Aerial surveys are frequently used to estimate the abundance of marine mammals, but their accuracy is dependent upon obtaining a measure of the avail?ability of animals to visual detection.
The Hunga Tonga–Hunga Ha?apai volcano erupted on 15 January 2022, launching Lamb waves and gravity waves into the atmosphere. In this study, we present results using 13 globally distributed meteor radars and identify the volcanogenic gravity waves in the mesospheric/lower thermospheric winds.
Australia’s record-breaking 2019/20 Black Summer fire weather resulted from a combination of natural and anthropogenic climate factors, but the full range of natural variability in fire weather is unknown.
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.
Free-living terrestrial mites (Acari) have persisted through numerous glacial cycles in Antarctica. Very little is known, however, of their genetic diversity and distribution, particularly within the Ross Sea region. To redress this gap, we sampled mites throughout the Ross Sea region…
While several processes have been identified to explain the decrease in atmospheric CO2 during glaciations, a better quantification of the contribution of each of these processes is needed. For … example…
Understanding how climate change influences ocean-driven melting of the Antarctic ice shelves is one of the greatest challenges for projecting future sea level rise. The East Antarctic ice shelf cavities host cold water masses that limit melting…
While satellite altimeters have revolutionized ocean science, validation measurements in high wave environments are rare. Using geodetic Global Navigation Satellite System (GNSS) data collected from the Southern Ocean Flux Station (SOFS; ?47°S, 142°E) since 2019…
The ANGWIN Antarctic Gravity Wave Instrument Network has the ability to measure gravity-wave characteristics at various locations and height ranges.
