Harbor
Harbor
Port Jackson, 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 manmade harbor will have sea walls or breakwaters and may require dredging. A natural harbor is surrounded on most sides by land. Harbors and ports are often confused. A port is a man-made coastal or riverine facility where boats and ships can load and unload. It may consist of quays, wharfs, jetties, piers and slipways with cranes or ramps. A port may have magazine buildings or warehouses for storage of goods and a transport system, such railway, road transport or pipeline transport facilities for relaying goods inland.

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, dependent on summer pack ice conditions.[1]
Artificial harbors
Artificial harbors are frequently built for use as ports. The largest artificially created harbor is in Rotterdam, The Netherlands.
Temporary harbors
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. Having a protected harbor reduces or eliminates the use of breakwaters as it will result in calmer waves inside the harbor.
St. John’s harbour, Newfoundland Sometimes a harbor is needed where one isn’t available due to damage, such as in times of war. In this case a temporary harbor may be built and transported in pieces to the location. The most notable of these were the two Mulberry harbours used during the DDay invasion of Normandy in World War II.
