Onepoto Volcanic Crater
Onepoto is the name of a volcanic explosion crater (or maar) on the North Shore in Auckland, New Zealand. It is a part of the Auckland volcanic field. History Located near the approaches to the Auckland Harbour Bridge, it was created by a series of eruptions approximately 185,000 years ago. The crater first became a freshwater lake, and later became a tidal lagoon when sea level rose to the present level 7,000 years ago after the last ice age. The crater's floor has been reclaimed, with recreational sports fields and a pond, and some parts of the tuff ring were quarried away in the 1950s to provide fill for the Northern Motorway.''Onepoto and Tank Farm'' - ''City of Fire'', insert magazine in ''The New Zealand Herald'', Friday 15 February 2008. Onepoto and neighbouring Tank Farm were fresh water lakes when sea levels were lower using the Last Glacial Maximum. As sea levels rose, the waters of the Waitematā Harbour breached the tuff rings of the craters, becoming tidal l ...

The New Zealand Herald
''The New Zealand Herald'' is a daily newspaper published in Auckland, New Zealand, owned by New Zealand Media and Entertainment, and considered a newspaper of record for New Zealand. It has the largest newspaper circulation of all newspapers in New Zealand, peaking at over 200,000 copies in 2006, although circulation of the daily ''Herald'' had declined to 100,073 copies on average by September 2019. Its main circulation area is the Auckland region. It is also delivered to much of the upper North Island including Northland, Waikato and King Country. History ''The New Zealand Herald'' was founded by William Chisholm Wilson, and first published on 13 November 1863. Wilson had been a partner with John Williamson in the ''New Zealander'', but left to start a rival daily newspaper as he saw a business opportunity with Auckland's rapidly growing population. He had also split with Williamson because Wilson supported the war against the Māori (which the ''Herald'' termed "the ...

Maars Of New Zealand
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar. The name comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. Notes: * According to German Wikipedia's ''"Maar"'' article, in 1544 in his book ''Cosmographia'', Sebastian Münster (1488–1552) first applied the word "maar" (as ''Marh'') to the Ulmener Maar and the Laacher See. See: Sebastian Münster, ''Cosmographia'' (Basel, Switzerland: Heinrich Petri, 1544)p. 341. From p. 341: ''"Item zwen namhafftiger seen seind in der Eyfel / einer bey de schloß Ulmen / und ein ander bey dem Closter züm Laich / die seind sere tieff / habe kein ynflüß aber vil außflüß / die nennet man Marh unnd seind fischreich."''

Auckland Libraries
Auckland Libraries is the public library system for the Auckland Region of New Zealand. It was created when the seven separate councils in the Auckland region merged in 2010. It is currently the largest public-library network in the Southern Hemisphere with 55 branches from Wellsford to Waiuku. Currently from March 2021, the region has a total of 56 branches. History In November 2010, Auckland's local councils merged to create the Auckland Council. As a result of this process, the seven public library systems within the region were combined to form Auckland Libraries. The following library networks were amalgamated, forming Auckland Libraries: * Auckland City Libraries * Bookinopolis (in the Franklin District) * Manukau Libraries * North Shore Libraries * Papakura Library ServicesThe Sir Edmund Hillary Library * Rodney Libraries * Waitakere Libraries The process of amalgamation In the years leading up to the merger of the library systems within Auckland, the separate library ...

Onepoto Bridge
Onepoto Bridge is a long pedestrian and cyclist bridge crossing the tidal stream outlet of the Onepoto volcanic crater in Northcote, Auckland. The bridge became necessary after widening of Onewa Road towards State Highway 1 made the existing bridge too narrow to carry footpaths. After deciding to build a new bridge, North Shore City Council resolved to construct an iconic structure that would create "architecture integrated into the landscape". This resulted in the bridge structure being encased with wooden curved 'ribs' that have been described as a whale skeleton, a wave or a half-finished sailing ship. The bridge was designed by Beca Group.''Bridging the gap between art and utility'' – ''LG – New Zealand Local Government'', volume 44 No 5, May 2008, Page 15 The bridge is also part of North Shore City's strategic cycle route network and incorporated into works to better access the local estuarial area for the community.

Waitematā Harbour
Waitematā Harbour is the main access by sea to Auckland, New Zealand. For this reason it is often referred to as Auckland Harbour, despite the fact that it is one of two harbours adjoining the city. The harbour forms the northern and eastern coasts of the Auckland isthmus and is crossed by the Auckland Harbour Bridge. It is matched on the southern side of the city by the shallower waters of the Manukau Harbour. With an area of , it connects the city's main port and the Auckland waterfront to the Hauraki Gulf and the Pacific Ocean. It is sheltered from Pacific storms by Auckland's North Shore, Rangitoto Island, and Waiheke Island. Etymology The oldest Māori name of the harbour was Te Whanga-nui o Toi (The Big Bay of Toi), named after Toi, an early Māori explorer. The name ''Waitematā'' means "Te Mata Waters", which according to some traditions refers to a mauri stone (a stone of Māori religious significance) called Te Mata, which was placed on Boat Rock (in the ha ...

Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing drought, desertification, and a large drop in sea levels. Based on changes in position of ice sheet margins dated via terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets commenced 33,000 years ago and maximum coverage was between 26,500 years and 19–20,000 years ago, when deglaciation commenced in the Northern Hemisphere, causing an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fluctuations around the Strait of Magellan suggest the peak in glacial surface area was constrained to betwee ...

Tank Farm
Tank Farm (sometimes Tuff Crater) is the name of a volcanic explosion crater (or maar) on the North Shore of Auckland, New Zealand, near the approaches to the Auckland Harbour Bridge. Geology Part of the Auckland volcanic field, it was created by a series of explosive eruptions. Although its age is unknown it could be one of the older volcanoes in Auckland like its neighbours Onepoto and Lake Pupuke. Originally a freshwater lake, it later became a tidal lagoon when the sea levels rose after the last ice age. Tank Farm is mostly in its natural state, though some parts of the tuff ring were quarried and its name stems from the petrochemicals storage tanks located here during World War II.''Onepoto and Tank Farm'' - ''City of Fire'', insert magazine in ''The New Zealand Herald'', Friday 15 February 2008. Tank Farm and neighbouring Onepoto were fresh water lakes when sea levels were lower using the Last Glacial Maximum. As sea levels rose, the waters of the Waitematā Harbour b ...

Auckland Northern Motorway
The Auckland Northern Motorway (known locally as the Northern Motorway, and historically as the Auckland–Waiwera Motorway) in the Auckland Region of New Zealand links Central Auckland and Puhoi in the former Rodney District via the Hibiscus Coast and North Shore. It is part of State Highway 1. It is in length, with 15 junctions. Until the end of the 1980s, it was largely associated with the Auckland Harbour Bridge as a connection between central Auckland and the North Shore, but since 1994 it has been extended to Puhoi to become the primary route between the Auckland urban area, the Hibiscus Coast satellite towns, the northern Rodney district, and Northland. Between the 1959 opening of the motorway and 1984, tolls were collected on the Auckland Harbour Bridge, and since 2009 tolls have been collected on the Northern Gateway Toll Road, the northernmost section of the motorway, bypassing the Hibiscus Coast. The Northern Motorway sees heavy traffic, with around 170,000 ve ...

Land Reclamation
Land reclamation, usually known as reclamation, and also known as land fill (not to be confused with a waste landfill), is the process of creating new land from oceans, seas, riverbeds or lake beds. The land reclaimed is known as reclamation ground or land fill. In some jurisdictions, including parts of the United States, the term "reclamation" can refer to returning disturbed lands to an improved state. In Alberta, Canada, for example, reclamation is defined by the provincial government as "The process of reconverting disturbed land to its former or other productive uses." In Oceania, it is frequently referred to as land rehabilitation. History One of the earliest large-scale projects was the Beemster Polder in the Netherlands, realized in 1612 adding of land. In Hong Kong the Praya Reclamation Scheme added of land in 1890 during the second phase of construction. It was one of the most ambitious projects ever taken during the Colonial Hong Kong era.Bard, Solomon. 002 ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...
