Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over .

Dundee Island
Dundee Island is an ice-covered island lying east of the northeastern tip of Antarctic Peninsula and south of Joinville Island. It is named after the city of Dundee in Scotland. The Petrel Base is a scientific station in Antarctica belonging to Argentina. Its coordinates are 63 ° 28′S 56 ° 17′W and it is located on rocks at 18 meters above sea level at the foot of the Rosamaría glacier in the Petrel bay, the low point of Cape Welchness on Dundee Island in the Joinville archipelago. A 10-year plan began in 2013 to convert it into a permanent base. The base infrastructure has 3600 m² under roof, a 1200 m² logistics area and 25 beds. Account for transport: 2 Zodiac with outboard motor and 1 all-terrain truck of 1.5 ton. It is from this island that the American businessman Lincoln Ellsworth, accompanied by the pilot Herbert Hollick-Kenyon, took off on the 23 November 1935 for the first crossing of the Antarctic by plane.
