Ongulkalven Island (Ongulkalven Island)
The Flatvaer Islands (Flatvær, meaning "flat islands"), also known as the Ongul Islands, are a group of small islands lying at the east side of the entrance of Lützow-Holm Bay, 4 km from the coastline of Antarctica. They were mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition (LCE), 1936–37. Many of the islands and their features were subsequently named by members of the Japanese Antarctic Research Expedition (JARE); unless otherwise noted, features noted in this article were named by JARE.

The Flatvaer Islands are separated from Lützow-Holm Bay by Ongul Sound, which is 2 mi wide and named in association with Ongul Island. On its east margin, opposite East Ongul Island, sits a small cluster of rocks called the Mukai Rocks. The name Mukai-iwa, meaning "facing rocks" or "opposite rocks," was given by JARE Headquarters in 1972.

The largest of the Flatvaer Islands is Ongul Island, at 1.5 nmi long. When initially surveyed, the LCE believed this island to be connected to East Ongul Island, a 1 nmi island immediately east of the northern part of Ongul Island. The LCE applied the name "Ongul" ("fishhook"), which is suggestive of the outline of the two islands when taken together. In 1957, the Japanese Antarctic Research Expedition (JARE) discovered that "Ongul" was actually two islands, separated by the Nakano-seto Strait, meaning "central strait". The name Ongul Island was retained for the largest island in the group, and the smaller island was given the name East Ongul Island. Showa Station, a Japanese permanent research station, was built on East Ongul Island in 1957.

Lake O-ike ("big pond") is a lake in the east extremity of Ongul Island, so named because it is the largest lake on the island. Shōwa Flat is a small flattish area along the northwest shore of the lake. It was named Shōwa-taira ("Emperor Hirohito's era flat"), presumably in association with Showa Station.

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.
