Greater Mackellar Island (Greater Mackellar Island)
Greater Mackellar Island, also Great Mackellar Islet, is the largest of the Mackellar Islands, lying 2 nmi north of Cape Denison in the center of Commonwealth Bay, Antarctica. It was discovered and named by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson. The Island is about 1100 m long, and up to 500 m wide.
The island forms part of the Mackellar Islands Important Bird Area (IBA), identified as such by BirdLife International because it supports large breeding colonies of Adélie penguins.

Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14200000 km2. Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km.
Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 m. Antarctica holds the record for the lowest measured temperature on Earth, −89.2 C. The coastal regions can reach temperatures over 10 C in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation occurs, it is mostly in the form of lichen or moss.
