About Macquarie Island
- It is located around 1,500 km southeast of Tasmania, Australia, in the Pacific Ocean.
- It is located about halfway between Australia and Antarctica.
- The island is about 34 kilometers (21 miles) long and 5 kilometers (3 miles) wide.
- No people live there permanently today.
- The island is the exposed crest of the undersea Macquarie Ridge, raised to its present position where the Indo-Australian tectonic plate meets the Pacific plate.
- It is a site of major geoconservation significance, being the only place on earth where rocks from the earth’s mantle (6 km below the ocean floor) are being actively exposed above sea level.
- Macquarie Ridge is one of only 3 such ridges that impede the Antarctic Circumpolar Circulation.
- This results in distinct differences between the west and east sides of the ridge, which are used in different ways by different species.
- Although the island is treeless, there are a variety of native vegetation types, including grasses and many species of moss.
- There are a few small glacial lakes.
- Fauna: It is home to 4 species of penguins and 4 species of albatross, the island recorded 57 seabird species.
