Information About

Harbor




, Sydney , Australia ]]
A harbor or '''harbour''' (see Spelling Differences ), or '''haven''', is a place where ships may shelter from the Weather or are stored. Harbors can be man-made or natural. A man-made harbor will have sea walls or Breakwaters and may require Dredging . A natural harbor is surrounded on most sides by land.

Harbors and Port s are often confused. A port is a man-made Coast al or riverine facility where Boat s and Ship s can load and unload. It may consist of Quay s, Wharf s, Jetties , Piers and Slipway s with Cranes or ramps. A port may have magazine buildings or warehouses for storage of goods and a Transport system, such as Railway , Road Transport or Pipeline Transport facilities for relaying goods inland.


NATURAL HARBORS

A natural harbor is a Landform where a part of a Body Of Water is protected and deep enough to furnish anchorage. Natural harbors have long been of great Strategic and Economic importance. Many of the great cities of the world are located on a natural harbor.


ICE-FREE HARBORS

For harbors near the Poles , being Ice-free is an important advantage, ideally all-year round. Examples are Murmansk ( Russia ), Petsamo (Russia, formerly Finland ), Hammerfest , Vardø , and Prince Rupert ( Canada ). The southern-most harbor, at Antarctica's Winter Quarters Bay (77°50′S), presents a potentially ice-free harbor, depending upon summer Pack Ice conditions.
