Port Chalmers Time Ball
The Port Chalmers time ball is a Victorian maritime Greenwich Mean Time signal located on Aurora Terrace on top of Observation Point in the port of Port Chalmers, New Zealand. It was established in 1867 by the Otago Provincial Council. The time ball fell precisely at 1 p.m. daily. Originally triggered by a grandfather clock, from 1882 onwards a telegraph signal from Wellington took over this function. It was removed in 1970, but a replacement was restored to service in 2020. History Following the introduction of New Zealand's first time ball, established at Wellington in March 1864, proposals were put forward for the introduction of a similar time signaling device at Port Chalmers. Originally it was suggested by harbourmaster W. Thomson that a time gun be used in preference to a time ball, as at noon, ship masters are frequently on shore, and were more likely to hear a gun than observe a time ball. The gun would also indicate the time to the inhabitants of the town, many of whom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenwich Mean Time
Greenwich Mean Time (GMT) is the Local mean time, mean solar time at the Royal Observatory, Greenwich, Royal Observatory in Greenwich, London, counted from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon; as a consequence, it cannot be used to specify a particular time unless a context is given. The term 'GMT' is also used as Western European Time, one of the names for the time zone UTC+00:00 and, in UK law, is the basis for civil time in the United Kingdom. English speakers often use GMT as a synonym for Coordinated Universal Time (UTC). For navigation, it is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude); but this meaning can differ from UTC by up to 0.9s. The term GMT should thus not be used for purposes that require precision. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the S ...

Otago Harbour
Otago Harbour is the natural harbour of Dunedin, New Zealand, consisting of a long, much-indented stretch of generally navigable water separating the Otago Peninsula from the mainland. They join at its southwest end, from the harbour mouth. It is home to Dunedin's two port facilities, Port Chalmers (half way along the harbour) and at Dunedin's wharf (at the harbour's end). The harbour has been of significant economic importance for approximately 700 years, as a sheltered harbour and fishery, then deep water port. Geography The harbour was formed from the drowned remnants of the giant Dunedin Volcano, centred close to what is now Port Chalmers. The remains of this violent origin can be seen in the basalt of the surrounding hills. The last eruptive phase ended some ten million years ago, leaving the prominent peak of Mount Cargill. The ancient and modern channel runs along the western side of the harbour, the eastern side being shallow, with large sandbanks exposed at low tide. T ...

Port Chalmers
Port Chalmers is a town serving as the main port of the city of Dunedin, New Zealand. Port Chalmers lies ten kilometres inside Otago Harbour, some 15 kilometres northeast of Dunedin's city centre. History Early Māori settlement The original Māori name for Port Chalmers was or , which may have indicated the hill where the , or altar, was sited. is a later name meaning ‘full tide’ and refers to an incident in which a group of warriors decided to spend the night in a cave that once existed at what was later known as Boiler Point and pulled their canoes well above the high tide mark. Overnight the tide rose and beached canoes were set adrift. As some of them swam out to reclaim the canoes those onshore cried out “Koputai!, Koputai!”Bowman, pp. 1, 4, 8–10, 19, 20, 28, 70–71, 98–109, 156–166, 168, 169, 173–175, 177. When a peace was made between Kāti Māmoe and Kāi Tahu, about 1780, Koputai was one of two southern terminuses of Kāi Tahu territory. The ch ...

Navigational Equipment
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.Bowditch, 2003:799. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. History In the European medieval period, navigation was considered part of the set of '' seven mechanical arts'', none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open-ocean navigation; it was ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
