The blue whale (Balaenoptera musculus) is a listed endangered species under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. A distinct population of blue whales, the eastern Indian Ocean pygmy blue (EIOPB) whale…
We use Multi-Sensor Reanalysis and ground-based total ozone content (TOC) data to study total ozone variations in Antarctica near the dates of sudden stratospheric warmings (SSW). Three events were analyzed, including the warmings in 1988, 2002 (major warming), and 2019.
We review the scientific literature, especially from the past decade, on the impacts of human … activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and … temporal scales.

Macquarie Island, a small subantarctic island, is home to rockhopper, royal and king penguins, which are often infested with the globally distributed seabird tick, Ixodes uriae. A flavivirus, an orbivirus, a phlebovirus, and a nairovirus were isolated from these ticks and partial sequences obtained.
Sub-Antarctic islands have a diversity of origins in detail but most are volcanic and very young suggesting that they are short-lived and that the distribution would have been very different a few million years ago. They contrast with the common tourist brochure concept of oceanic islands.
