Jona Island (Jona, islote)
Jona Island is an island off the western coast of Graham Land on the Antarctic Peninsula. It is one of the smaller of the Bennett Islands, lying in Hanusse Bay 3 nmi north of the eastern end of Weertman Island and near Adelaide Island. It is within the Argentine, British and Chilean Antarctic claims.
The island was mapped from air photos taken by the Ronne Antarctic Research Expedition (1947–48) and the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57). It was named by the UK Antarctic Place-Names Committee for Franco P. Jona, an American (formerly Italian) physicist who in 1951 made an accurate determination of the elastic constant of a single ice crystal.

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.
