Coulman Island (Coulman Island)
Coulman Island is an ice-covered island in the Ross Sea, located 14 km southeast of Cape Jones, Victoria Land, Antarctica. It is 33.3 km long, 14.8 km wide and 6562 ft in elevation. Emperor penguins inhabit this island. It was discovered in 1841 by Sir James Clark Ross who named it for his father-in-law, Thomas Coulman. A notable landmark of this island is Cape Anne, the south-easternmost point of the island, so named by Sir James Clark Ross for his wife. Cape Wadworth is the northernmost point of the island.
The island is composed of several overlapping shield volcanoes that form part of the Hallett Volcanic Province of the McMurdo Volcanic Group. A 5 km wide and 700 m deep caldera called the Hawkes Heights can be found on the south end of the island.
The island was founded in 1841, however, the island is currently recognized as an important bird area because it holds a huge super-colony of emperor penguins and is the largest colony of this species in the world. However, scientists speculate that this colony could hold more birds than what they have estimated. More than 26,000 chicks have been counted during the 2018-2019 breeding season indicating that the number of adults ranged from 30,000 to 35,000 breeding pairs. The sheer numbers of penguins on the island had also led scientists to think that there have been potentially larger emperor penguin super-colonies that may have existed in the past before being wiped out during the last ice age.

Country - Antarctica
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.
