Meteoroids of sub-milligram sizes burn up high in the Earth's atmosphere and cause streaks of plasma trails detectable by meteor radars. The altitude at which these trails, or meteors…
Gravity waves provide a key mechanism for the vertical transport of energy and momentum from the active near-surface weather to the upper reaches of the neutral and ionised atmosphere. Generation mechanisms vary between storms, fronts…
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…
The impact that biogenic emissions have on aerosol-cloud interactions across the Southern Ocean is poorly quantified. Here we use satellite and ship observations during austral summer to study these interactions.
A computationally efficient algorithm to calculate the weighting coefficients required to evaluate derivatives for arbitrary multi-dimensional distributions of points is presented. The iterative algorithm guarantees IEEE 754 64-bit precision (at least 15 significant decimal digits)…
Individuals in isolated and extreme environments can experience debilitating side-effects including significant decreases in fat-free mass (FFM) from disuse and inadequate nutrition. The objective of this study was to determine the strengths and weaknesses of three-dimensional optical (3DO)…
We tracked adult emperor penguins from Rothschild Island, west Antarctic Peninsula in 2015/2016 during a summer with extensive sea ice of long duration, contrasting with past years of reduced sea ice extent associated with the recent, rapid, warming trend across the region.
To understand the scope and scale of the loss of biodiversity, tools are required that can be applied in a standardized manner to all species globally, spanning realms from land to the open ocean.
INTRODUCTION The Commission and the Scientific and Conservation Committees have adopted numerous recommendations over the years for strengthening engagement with other organisations. The IWC Secretariat, in collaboration with members of the SC and CC have been working to carry out these mandates…
Atmospheric gravity waves play an important role in transporting energy and momentum between atmospheric spheres and drive circulations that affect key processes such as formation of the ozone hole and the cold summer polar mesosphere.
In accordance with Article 6.3 of Annex V to the Protocol on Environmental Protection to the Antarctic Treaty, Australia has undertaken a five-yearly review of the management plan for Antarctic Specially Protected Area (ASPA) 101 Taylor Rookery.
