Macquarie Island

.

Macquarie Island is 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. This makes it an important focus of geological study.

The island lies in the southwest corner of the Pacific Ocean, about half-way between Australia and Antarctica. Fauna found on the island include: Subantarctic Fur Seals, Antarctic Fur Seals, New Zealand Fur Seals and Southern Elephant Seals - over 80,000 individuals of this species. Royal Penguins breed only on this island; King Penguins, Southern Rockhopper Penguins and Gentoo penguins also breed here.

  • Peat "Vast waterlogged areas on the coastal platform are heavily vegetated, forming a mire based on deep peat beds and known locally as "featherbed" from the sensation gained when walking over them. Old sea stacks testify to the continual uplifting of the island as they protrude through the peat beds, some of them now being several hundred metres from the existing coastline" (see link)
