Sea

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A sea generally refers to a large body of salt water, but the term is used in other contexts as well. Most commonly, it means a large expanse of saline water connected with an ocean, and is commonly used as a synonym for ocean.[1] It is also used sometimes to describe a large saline lake that lacks a natural outlet, such as the Caspian Sea.

Arctic (belonging to the Arctic Ocean) and Antarctic (Southern Ocean) seas, as well as some other seas freeze in winter. This occurs below the freezing point of pure water, at about -1.8 °C (28.8 °F). Frozen salt water becomes sea ice.[2]

[edit] History

Phoenician (yellow) and Greek (red) colonies in the Mediterranean in the 1st millennium BC

Humans navigated seas from antiquity. Ancient Egyptians and Phoenicians navigated the Mediterranean Sea and the Red Sea. Hannu was the first see explorer of whom there is any information. He sailed along the Red Sea and further to the Arabian Peninsula and the African Coast around 2750 BC.[3] In the 1st millennium BC, Phoenicians and Greeks established colonies all over the Mediterranean, including its outlets like the Black Sea. The seas along the eastern and the southern Asian coast were used by Arabs and Chinese for navigation, and the North Sea and the Baltic Sea were known to Europeans in Roman times. Other seas were not used for navigation in the antiquity and were actually discovered.

The White Sea was known to Novgorodians and used for navigation since not later that the 13th century.[4] Pomors, living at the White Sea coast, also sailed to Svalbard, but the Barents Sea got its name later, due to the 16th century Dutch expedition headed by Willem Barentsz. Other seas in Arctic Russia were explored in connection with the search of the Northern Sea Route. In the first half of the 17th century the Kara Sea was already used on a regular basis for navigation between the city of Arkhangelsk and the mouth of the Ob River and upstream to the city of Mangazeya (Mangazeya Trade Route) and to the mouth of the Yenisei River (Yenisey Trade Route).[5] In 1648, Semyon Dezhnev led an expedition down the Kolyma River, around the cape now known as Cape Dezhnev, and to the mouth of the Anadyr River.[6] By the end of the 17th century, the seas along what is now Arctic and Pacific coasts of Russia were already discovered, although the systematic description and reliable mapping of the coast line only started in the 18th century, and the geographical locations of all islands were only established in the first half of the 20th century, when aviation was employed.
