Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Sea Islands
The Coral Sea Islands Territory is an external territory of Australia which comprises a group of small and mostly uninhabited tropical islands and reefs in the Coral Sea, northeast of Queensland, Australia. The only inhabited island is Willis Island. The territory covers , most of which is ocean, extending east and south from the outer edge of the Great Barrier Reef and includes Heralds Beacon Island, Osprey Reef, the Willis Group and fifteen other reef/island groups. Cato Island is the highest point in the Territory.Geoscience AustraliaCoral Sea Islands History and status The Coral Sea Islands were first charted in 1803. In the 1870s and 1880s the islands were mined for guano but the absence of a reliable supply of fresh water prevented long-term habitation. The Coral Sea Islands became an Australian external territory in 1969 by the ''Coral Sea Islands Act'' (prior to that, the area was considered a part of Queensland) and extended in 1997 to include Elizabeth Reef ...

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...

Nautical Mile
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Reefs
Frederick Reef is in the Coral Sea Islands, over northeast of Gladstone, Queensland. The reef gets its name from ''Frederick'', which first reported sighting the reef. Frederick Reef is a small atoll with a large rock called Ridge Rock at the southern end, a sand cay called Observatory Cay, and a lighthouse at the northern end, which is the only permanently dry land, although there are a few of others cays that can be awash at high tide. The reef is around 30km2. The reefs are in a J shape that forms a semi-enclosed lagoon known as Anchorage Sound, with an opening on the North side. The complex measures about , with an area of . The reef is located in some deep water and drops sharply to over on the western side. General description The Frederick Reefs are a small group of remote reefs located beyond the southern reaches of the Great Barrier Reef, The reef complex lies due east from the city of Mackay, Queensland or northeast of the city of Gladstone.

Lihou Reef National Nature Reserve
Lihou Reef National Nature Reserve is a former marine protected area covering an area of 8440 km2 in the Australian Coral Sea Islands Territory that was incorporated into the new Coral Sea Commonwealth Marine Reserve in December 2012. Together with the Coringa-Herald National Nature Reserve, from which it is separated by about 100 km of open ocean, it forms the Coral Sea Reserves Ramsar Site, designated on 16 August 2002, listing it under the Ramsar Convention as a wetland of international importance. History Lihou Reef and its cays were discovered by Lieutenant John Lihou, R.N., on 23 February 1823. Lihou, then Master of the brig-sloop HMS ''Zenobia'', was on passage from Manila to South America. After a hazardous passage through the reef, the ship departed the Great Barrier Reef via an opening near Murray Islands.

Saumarez Reefs
Saumarez Reef is one of the southernmost reefs to be located in the Coral Sea Islands and part of the Coral Sea Shelf; it contains three main reefs and numerous smaller reefs all of which form a large crescent-shaped formation open to the northwest, about 27 by 14 km, area less than 300 km2.
