Te Waihora
Lake Ellesmere / Te Waihora is a broad, shallow coastal lake or waituna, in the Canterbury, New Zealand, Canterbury region of the South Island of New Zealand. It is directly to the west of Banks Peninsula, separated from the Pacific Ocean by the long, narrow, sandy Kaitorete Spit, or more correctly Kaitorete Barrier. It lies partially in extreme southeastern Selwyn District and partially in the southwestern extension of the former Banks Peninsula District, which now (since 2006) is a ward in the city of Christchurch. The lake holds high historical and cultural significance to the indigenous Māori language, Māori population and the traditional Māori name ''Te Waihora'', means ''spreading waters''. It has officially had a dual English/Māori name since at least 1938. Geography and hydrology Currently Lake Ellesmere / Te Waihora is a Brackish water, brackish bar-type waterbody, commonly called a lake or lagoon. It covers an area of , and is New Zealand's 5th largest lake (by ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selwyn District
Selwyn District is a predominantly rural district in central Canterbury, on the east coast of New Zealand's South Island. It is named after the Selwyn River / Waikirikiri, which is in turn named after Bishop George Selwyn, the first Anglican bishop of New Zealand who, in 1843 and 1844, travelled the length of the country by horse, foot, boat and canoe, leaving in his wake a sprinkling of locations that now bear his name. History The first inhabitants of the area were the Māori who first settled New Zealand from the Cook and Society Islands about 700 years ago. The predominant Māori tribe today, in Selwyn and most of the rest of the South Island, is Ngāi Tahu, whose local marae (meeting house) is at Taumutu near the exit of Lake Ellesmere (Te Waihora). In the late 19th century, European (chiefly British) colonists arrived and carved the area up into farmland. This has remained the predominant pattern ever since. The Selwyn District as a unit of government was formed in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washdyke Lagoon
Washdyke Lagoon is a brackish shallow coastal lagoon approximately north of Timaru, South Canterbury, New Zealand. The lagoon has drastically reduced in size since 1881 when it was approximately , now it is less than in area. It is enclosed by a barrier beach that is long and above high tide at its largest point (see Figure 1). The reduced lagoon size is due to the construction of the Timaru Port breakwater which is preventing coarse sediments from reaching and replenishing Washdyke Barrier. This is important as the lagoon and the surrounding are classified as a wildlife refuge and it demonstrates the role human structures have on coastline evolution.Kirk, R. M. & Lauder, G. A. (2000). Significant coastal lagoon systems in the South Island, New Zealand. ''Science for conservation 146.'' Classification Washdyke Lagoon is a coastal lake, ‘choked’ type lagoon as it is separated from the sea by a built-up bar, and has only minimal tidal input (<5% of total tidal impact to coast ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
