Natural Harbor
A harbor (American English), or harbour (Commonwealth English; see spelling differences), is a sheltered body of water where ships, boats, and barges can be moored. The term ''harbor'' is often used interchangeably with ''port'', which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers. Harbors usually include one or more ports. Alexandria Port in Egypt, meanwhile, is an example of a port with two harbors. Harbors may be natural or artificial. An artificial harbor can have deliberately constructed breakwaters, sea walls, or jetties or they can be constructed by dredging, which requires maintenance by further periodic dredging. An example of an artificial harbor is Long Beach Harbor, California, United States, which was an array of salt marshes and tidal flats too shallow for modern merchant ships before it was first dredged in the early 20th century. In contrast, a natural harbor is surrounded on several sides by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Khufu succeeded his father Sneferu as king. He is generally accepted as having commissioned the Great Pyramid of Giza, one of the Seven Wonders of the Ancient World, but many other aspects of his reign are poorly documented.Thomas Schneider: ''Lexikon der Pharaonen''. Albatros, Düsseldorf 2002, , page 100–104. The only completely preserved portrait of the king is a Khufu Statuette, small ivory figurine found in a temple ruin of a later period at Abydos, Egypt, Abydos in 1903. All other reliefs and statues were found in fragments, and many buildings of Khufu are lost. Everything known about Khufu comes from inscriptions in his necropolis at Giza pyramid complex, Giza and later documents. For example, Khufu is the main character noted in the Westcar Papyrus ...

Wadi Al-Jarf
Wadi al-Jarf () is an area on the Red Sea coast of Egypt, south of Suez, that is the site of the oldest known artificial harbour in the world, developed about 4500 years ago. It is located at the mouth of the Wadi Araba, a major communication corridor between the Nile Valley and the Red Sea, crossing the Eastern Desert. The site is across the Gulf of Suez from the small Sinai fortress of Tell Ras Budran. A somewhat similar ancient port is at Ain Sukhna, a little north of Wadi al-Jarf. The site was first discovered by John Gardner Wilkinson, J. G. Wilkinson in 1832. It was rediscovered by a French team in the 1950s, who named it Rod el-Khawaga. Archeological work was quickly abandoned when the Suez Crisis broke out in 1956. A joint French–Egyptian team resumed excavation in 2011. The harbor at the site dates to the Fourth Dynasty of Egypt, approximately 4,500 years ago. Also discovered at the site were more than 100 anchors, the first Old Kingdom anchors found in their original ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Halifax Harbour
Halifax Harbour is a large natural harbour on the Atlantic coast of Nova Scotia, Canada, located in the Halifax Regional Municipality. Halifax largely owes its existence to the harbour, being one of the largest and deepest ice-free natural harbours in the world. Before Confederation it was one of the most important commercial ports on the Atlantic seaboard. In 1917, it was the site of the world's largest man-made accidental explosion, when the blew up in the Halifax Explosion on December 6. The harbour was formed by a drowned glacial valley which succumbed to sea level rise after glaciation. The Sackville River now empties into the upper end of the harbour in Bedford Basin. The harbour also includes the Northwest Arm and The Narrows, a constricted passage to Bedford Basin. Halifax Harbour has been polluted as a result of two centuries of direct raw sewage discharge into its waters. Health concerns in the 1990s caused the shut-down of all harbour beaches.

Sydney Harbour
Port Jackson, commonly known as Sydney Harbour, is a ria, natural harbour on the east coast of Australia, around which Sydney was built. It consists of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove River, Lane Cove and Parramatta River, Parramatta Rivers. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of significant landmarks such as the Sydney Opera House and Sydney Harbour Bridge. The location of the History of Australia, first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. Port Jackson, in the early days of the colony, was also used as a Metonymy, shorthand for Sydney and its environs. Thus, many botanists, see, e.g., Robert Brown (botanist, born 1773), Robert Brown's ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', described their specimens as having been collected at Port Jackson. ...

Merchant Ships
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes. They come in a myriad of sizes and shapes, from inflatable dive boats in Hawaii, to 5,000-passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to oil tankers and container ships at major ports, to passenger-carrying submarines in the Caribbean. Many merchant ships operate under a "flag of convenience" from a country other than the home of the vessel's owners, such as Liberia and Panama, which have more favorable maritime laws than other countries. The Greek merchant marine is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world's tonnage; this makes it currently the largest single international merchant fleet in the world, albeit no ...

Tidal Flats
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least of the Earth's surface. / They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes (or inland seas) alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. A recent global remote sensing analysis estimated that approximately 50% of the global extent of tidal flats occurs within eight countries (Indonesia, China ...

Salt Marshes
A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open Seawater, saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of halophyte, salt-tolerant plants such as herbs, Poaceae, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal management, coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through Coastal ero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
