Data collection facilitated by remotely piloted aircraft (RPA) has proven to be revolutionary in many disciplines including for research in extreme environments. Here we assess current use and utility of small multirotor remotely piloted aircraft (RPAs)…
The large-scale exploitation of whale populations in the whaling era led to the near extirpation of large whales all over the world. This must have had major repercussions for marine ecosystems globally.
Global sea levels are rising due, in large part, to the increase in the rate of melting of ice sheets as a direct result of climate change. A large fraction of uncertainty in future sea level rise comes from limited understanding of basal conditions under ice sheets. Specifically…
The presence of unique biological archives (e.g., springtails, Arthropoda: Collembola) in Antarctic ice-free regions provides powerful evidence for testing assumptions about when and how the current ice sheet reached its present-day configuration. Springtails, where present, may suggest long-term…
Accelerated warming since the 1950s has caused dramatic change to ice shelves and outlet glaciers on the Antarctic Peninsula. Long observational records of ice loss in Antarctica are rare but essential to accurately inform mass balance estimates of glaciers. Here…
A brief review of key ice core research in Greenland and Antarctica
A review of ice core atmospheric nitrous oxide reconstructions including concentrations and stable isotope ratios (N and O).
Heard Island and McDonald Islands (HIMI) are an external Territory of Australia, located approximately 4000 kilometres southwest of Australia in the southern Indian Ocean.
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)…
The additional water from the Antarctic ice sheet and ice shelves due to climate-induced melt can impact ocean circulation and global climate. However, the major processes driving melt are not adequately represented in Coupled Model Intercomparison Project phase 6 (CMIP6) models. Here…
The variations of atmospheric ?14C over the past two millennia are classically attributed to changes in its production rate in the upper atmosphere, which in turn is related to changes in solar activity and the Earth's magnetic field. However…
The contamination of the marine environment surrounding coastal Antarctic research stations remains insufficiently understood in terms of its extent, persistence, and characteristics. We investigated the presence of contaminants in marine sediments near Casey Station…
Antarctica has experienced major changes in temperature, wind speed and stratospheric ozone levels over the last 50 years. Whilst West Antarctica and the peninsula have shown rapid warming and consequent ecosystem change, East Antarctica appeared to be little impacted by climate warming…
The Antarctic ozone hole of 2011 is reviewed from a variety of perspectives, making … use of various data and analyses. The ozone hole of 2011 was relatively large … in terms of maximum area, minimum ozone level and total ozone deficit…
Although many Quaternary records have allowed the study of major glacial-interglacial change in the … Southern Ocean, Holocene records from deep-sea cores are few and far between and are currently … limited to the South Atlantic. Low sedimentation rates combined with deep seafloors…
Developing water quality guidelines for Antarctic marine environments requires understanding sensitivity of biota to contaminant exposure. Toxicity tests with Antarctic … invertebrates have shown response times to metal exposure takes far longer than the durations of standard bioassay methods.
