Brown-water Navy
A brown-water navy or riverine navy, in the broadest sense, is a naval force capable of military operations in inland waters (rivers, lakes and inland seas) and nearshores. The term originated in the United States Navy during the American Civil War, when it referred to Union forces patrolling the muddy Mississippi River, among others, and has since been used to describe the small gunboats and patrol boats commonly used in rivers, along with the larger "mother ships" that supported them, which include converted World War II-era mechanized landing craft and tank landing ships, among other vessels. Brown-water navies are typically only used for patrolling and enforcing internal waters, in contrasted with seaworthy blue-water navies, which can independently conduct operations in the open oceans and project power far offshore. Green-water navies, which operate mainly in brackish estuaries, bays and shallow seas not too far off coasts (typically within the bounds of exc ...

Open Ocean
The pelagic zone consists of the water column of the open ocean and can be further divided into regions by depth. The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. In a manner analogous to stratification in the Earth's atmosphere, the water column can be divided vertically into up to five different layers (illustrated in the diagram), with the number of layers depending on the depth of the water. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirri ...

Company Of Watermen And Lightermen
The Company of Watermen and Lightermen (CWL) is a historic City guild in the City of London. However, unlike the city's 111 livery companies, CWL does not have a grant of livery. Its meeting rooms are at Waterman's Hall on St Mary at Hill, London. The role of watermen was to transfer passengers, while lightermen moved goods and cargo, between the Port of London and vessels moored in the River Thames. Although modern river workers are licensed by the Maritime and Coastguard Agency, the company continues its roles arranging apprenticeships, lobbying on river matters, and organising historic annual events and ceremonies. The company's clerk is Julie Lithgow, formerly director of the Institute of Chartered Shipbrokers. History CWL was established in the medieval period to support and maintain rights of the river workers. The two main occupations were that of watermen and lightermen. The watermen transferred passengers across and along city centre rivers and estuaries. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's Bargemaster
The King's Bargemaster is a subordinate officer of the Royal Household of the Sovereign of the United Kingdom. Until the mid-19th century, the Royal Family frequently used a royal barge for transport along the River Thames. The role of the King's Bargemaster was to oversee this. The tradition of the Bargemaster dates back to 1215, with the signing of Magna Carta at Runnymede. The role is now largely ceremonial. The Bargemaster is responsible for the Royal Watermen, chosen from the ranks of the Thames Watermen who operate tugs and launches on the river. There are 24 Royal Watermen, each of whom receives an annual salary of £3.50. Duties The ceremonial duties include state occasions involving the Thames. In recent years for example, they have helped organise and facilitate river Pageants for the Golden Jubilee and Diamond Jubilee. Onshore duties include acting as footmen on royal carriages during State visits, royal weddings and jubilees. At the coronation, the Royal Water ...

Royal Barge
A royal barge is a vessel that is used by a monarch for ceremonial processions, and (historically) for routine transport, usually on a river or inland waterway. It may also be known as a state barge, and may be used on occasion by other members of a royal family, heads of state, or particular VIPs. Traditionally royal barges were used by European monarchies such as United Kingdom, France, Belgium, and Sweden, and Southeast Asian monarchies such as Siam, Burma, Brunei, Riau and Cambodia. In more recent years, royal barges have only been used in the United Kingdom, Sweden and Thailand. Belgium In the 19th century, when a head of state visited a port city, it was traditional to invite them aboard a royal barge. This was why the Belgian government decided, on the recommendation of the King Leopold I, to have the Lecarpentier shipyards in Antwerp build a royal barge. Launched on 12 July 1835, ''Canot Royal'' carried the royal couple for the first time from Brussels to Antwerp vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rowing
Rowing is the act of propelling a human-powered watercraft using the sweeping motions of oars to displace water and generate reactional propulsion. Rowing is functionally similar to paddling, but rowing requires oars to be mechanically attached to the boat, and the rower drives the oar like a lever, exerting force in the ''same'' direction as the boat's travel; while paddles are completely hand-held and have no attachment to the boat, and are driven like a cantilever, exerting force ''opposite'' to the intended direction of the boat. In some strict terminologies, using oars for propulsion may be termed either "pulling" or "rowing", with different definitions for each. Where these strict terminologies are used, the definitions are reversed depending on the context. On saltwater a "pulling boat" has each person working one oar on one side, alternating port and starboard along the length of the boat; whilst "rowing" means each person operates two oars, one on each side of ...

River Thames
The River Thames ( ), known alternatively in parts as the The Isis, River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the Longest rivers of the United Kingdom, second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west, it flows through Oxford (where it is sometimes called the Isis), Reading, Berkshire, Reading, Henley-on-Thames and Windsor, Berkshire, Windsor. The Thames also drains the whole of Greater London. The lower Reach (geography), reaches of the river are called the Tideway, derived from its long Tidal river, tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the estuary, the Thames drops by . Running through some of the drier parts of mainland Bri ...

Exclusive Economic Zone
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine natural resource, resources, including energy production from water and wind. It stretches from the outer limit of the territorial sea (22.224 kilometres or 12 nautical miles from the baseline) out 370.4 kilometres (or 200 nautical miles) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the Territorial waters#Territorial sea, territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's righ ...

Coast
A coast (coastline, shoreline, seashore) is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape and by aquatic erosion, such as that caused by wind wave, waves. The geology, geological composition of rock (geology), rock and soil dictates the type of shore that is created. Earth has about of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor ecosystems, such as freshwater marsh, freshwater or estuary, estuarine wetlands, that are important for birds and other terrestrial animals. In wave-protected areas, coasts harbor salt marshes, mangroves, and seagrass meadow, seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic animals. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessility (motility), sessile ...

Neritic Zone
The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately in depth. From the point of view of marine biology it forms a relatively stable and well-illuminated environment for marine life, from plankton up to large fish and corals, while physical oceanography sees it as where the oceanic system interacts with the coast. Definition (marine biology), context, extra terminology In marine biology, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to the zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone. It extends from the low tide mark to the edge of the continental shelf, with a relatively shallow depth extending to about 200 meters (660 feet). Above the neritic zone lie the intertidal (or eulittoral) and supralittoral zones; below it the continental slope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as ba ...
