The Indian Ocean is the third-largest of the world's five oceanic divisions, covering 70,560,000 km2 (27,240,000 sq mi) or approx. 20% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean, or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has large marginal, or regional seas, such as the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea.
The geography of Israel is very diverse, with desert conditions in the south, and snow-capped mountains in the north. Israel is located at the eastern end of the Mediterranean Sea in West Asia. It is bounded to the north by Lebanon, the northeast by Syria, the east by Jordan and the West Bank, and to the southwest by Egypt. To the west of Israel is the Mediterranean Sea, which makes up the majority of Israel's 273 km (170 mi) coastline, and the Gaza Strip. Israel has a small coastline on the Red Sea in the south.
This is a list of the lists of islands in the world grouped by country, by continent, by body of water, and by other classifications. For rank-order lists, see the other lists of islands below.
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant in West Asia. The Mediterranean has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago.
The Sea of Galilee, also called Lake Tiberias or Kinneret, is a freshwater lake in Israel. It is the lowest freshwater lake on Earth and the second-lowest lake in the world, at levels between 215 and 209 metres below sea level. It is approximately 53 km (33 mi) in circumference, about 21 km (13 mi) long, and 13 km (8.1 mi) wide. Its area is 166.7 km2 (64.4 sq mi) at its fullest, and its maximum depth is approximately 43 metres (141 ft). The lake is fed partly by underground springs, but its main source is the Jordan River, which flows through it from north to south and exits the lake at the Degania Dam.
Tiberias is an Israeli city on the western shore of the Sea of Galilee. A major Jewish center during Late Antiquity, it has been considered since the 16th century one of Judaism's Four Holy Cities, along with Jerusalem, Hebron, and Safed. In 2022, it had a population of 48,472.
Geographical exploration, sometimes considered the default meaning for the more general term exploration, refers to the practice of discovering remote lands and regions of the planet Earth. It is studied by geographers and historians.
Magdala was an ancient Jewish city on the shore of the Sea of Galilee, 5 km north of Tiberias. In the Babylonian Talmud it is known as Magdala Nunayya, and which some historical geographers think may refer to Tarichaea, literally: "the place of processing fish." It is believed to be the birthplace of Mary Magdalene. Until the 1948 Arab–Israeli War, a small Arab village, al-Majdal, stood at the site of ancient Magdala. The Israeli municipality of Migdal now extends into the area.
Ocean exploration is a part of oceanography describing the exploration of ocean surfaces. Notable explorations were undertaken by the Greeks, the Romans, the Polynesians, the Phoenicians, Phytheas, Herodotus, the Vikings, the Portuguese and Muslims. Scientific investigations began with early scientists such as James Cook, Charles Darwin, and Edmund Halley. Ocean exploration itself coincided with the developments in shipbuilding, diving, navigation, depth, measurement, exploration, and cartography.
Triple Divide Peak is located in the Lewis Range, part of the Rocky Mountains in North America. The peak is a feature of Glacier National Park in the state of Montana in the United States. The summit of the peak, the hydrological apex of the North American continent, is the point where two of the principal continental divides in North America converge, the Continental Divide of the Americas and the Northern or Laurentian Divide.
USS Ainsworth (DE/FF-1090) was a Knox-class frigate named for Vice Admiral Walden L. Ainsworth (1886–1960). Ainsworth (DE-1090) was laid down at Westwego, Louisiana, on 11 June 1971 by Avondale Shipyards, Inc.; launched on 15 April 1972; sponsored by Mrs. Katharine Gardner Ainsworth, the widow of Vice Admiral Ainsworth; and commissioned on 31 March 1973 at the Norfolk Naval Shipyard, Portsmouth, Virginia.
A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea. Every continent on earth except Antarctica has at least one continental drainage divide; islands, even small ones like Killiniq Island on the Labrador Sea in Canada, may also host part of a continental divide or have their own island-spanning divide. The endpoints of a continental divide may be coastlines of gulfs, seas or oceans, the boundary of an endorheic basin, or another continental divide. One case, the Great Basin Divide, is a closed loop around an endorheic basin. The endpoints where a continental divide meets the coast are not always definite since the exact border between adjacent bodies of water is usually not clearly defined. The International Hydrographic Organization's publication Limits of Oceans and Seas defines exact boundaries of oceans, but it is not universally recognized. Where a continental divide meets an endorheic basin, such as the Great Divide Basin of Wyoming, the continental divide splits and encircles the basin. Where two divides intersect, they form a triple divide, or a tripoint, a junction where three watersheds meet.
The following outline is provided as an overview of and introduction to Oceanography.
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of 20,327,000 km2 (7,848,000 sq mi), it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean.
The borders of the oceans are the limits of Earth's oceanic waters. The definition and number of oceans can vary depending on the adopted criteria. The principal divisions of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean. Smaller regions of the oceans are called seas, gulfs, bays, straits, and other terms. Geologically, an ocean is an area of oceanic crust covered by water.
Fishing in Israel is a branch of the Israeli economy with historical significance. The three main natural fishing zones are the Mediterranean Sea, the Gulf of Aqaba, and the Kinneret. A fourth area that was once historically significant, Lake Hula, no longer exists, as it was drained in the 1950s. In addition, aquaculture the growth of fish in ponds or in cages, is rising in prominence.
