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 ...

Barrier Beach
Barrier islands are coastal landforms and a type of dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend uninterrupted for over a hundred kilometers, excepting the tidal inlets that separate the islands, the longest and widest being Padre Island of Texas, United States. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. The length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends, and basemen ...

Basking Shark
The basking shark (''Cetorhinus maximus'') is the second-largest living shark and fish, after the whale shark, and one of three plankton-eating shark species, along with the whale shark and megamouth shark. Adults typically reach in length. It is usually greyish-brown, with mottled skin, with the inside of the mouth being white in color. The caudal fin has a strong lateral keel and a crescent shape. Other common names include bone shark, elephant shark, sail-fish, and sun-fish. In Orkney, it is commonly known as hoe-mother (sometimes contracted to homer), meaning "the mother of the pickled dog-fish". The basking shark is a cosmopolitan migratory species, found in all the world's temperate oceans. A slow-moving filter feeder, its common name derives from its habit of feeding at the surface, appearing to be basking in the warmer water there. It has anatomical adaptations for filter-feeding, such as a greatly enlarged mouth and highly developed gill rakers. Its snout is conic ...

Southern Elephant Seal
The southern elephant seal (''Mirounga leonina'') is one of two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest extant marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season. A bull southern elephant seal is about 40% heavier than a male northern elephant seal (''Mirounga angustirostris''), twice as heavy as a male walrus (''Odobenus rosmarus''), and 6–7 times heavier than the largest living mostly-terrestrial carnivoran, the polar bear (''Ursus maritimus'') and the Kodiak bear (''Ursus arctos middendorffi''),. Taxonomy The southern elephant seal was one of the many species originally described by Swedish zoologist Carl Linnaeus in the landmark 1758 10th edition of his ''Systema Naturae'', where it was given the binomial name of ''Phoca leonina''.

Darfield, New Zealand
Darfield is a town in the Selwyn District of the South Island of New Zealand. It is 35 kilometres west of the outskirts of Christchurch. Its population is as of . Darfield is the main town between Christchurch and the West Coast region. It is often called "The township under the nor'west arch" in reference to a characteristic weather phenomenon that often creates an arch of cloud in an otherwise clear sky to the west of the township. This is caused by the condensation of water particles channelled upwards over the Southern Alps / Kā Tiritiri o te Moana. Darfield lies in the Malvern district's arable and pastoral farming area. It is a gateway to the scenic Waimakariri and Rakaia rivers and the Southern Alps, and is also a popular lift-off place for hot air ballooning. Darfield is located around the former junction of the railway lines coming from Christchurch and going to Whitecliffs (where coal was mined) and Springfield and on to the West Coast.

Rakaia Gorge
The Rakaia Gorge is located on the Rakaia River in inland Canterbury in New Zealand's South Island. Like its neighbour, the Waimakariri River, the Rakaia runs through wide shingle beds for much of its length, but is forced through a narrow canyon as it approaches the Canterbury Plains. In the 1870s, there were proposals to extend the Whitecliffs Branch railway into the Rakaia Gorge, and an 1880 Royal Commission on New Zealand's railway network was in favour of this proposal, but it never came to fruition. The Rakaia Gorge bridge was completed in 1882 and provides an inland alternative to the more frequently used Rakaia River bridge just north of the town of Rakaia. The bridge carries State Highway 77 and the Inland Scenic Route and connects the settlements of Glentunnel and Methven Swimming at the top bridges of the gorge is a favoured pastime for locals and tourists alike. Swimming in the main river can be done but only by strong swimmers. There is a perfect swimming ho ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Waimakariri River
The Waimakariri River is one of the largest rivers in Canterbury, on the eastern coast of New Zealand's South Island. It flows for in a generally southeastward direction from the Southern Alps across the Canterbury Plains to the Pacific Ocean. The river rises on the eastern flanks of the Southern Alps, eight kilometres southwest of Arthur's Pass. For much of its upper reaches, the river is braided, with wide shingle beds. As the river approaches the Canterbury Plains, it passes through a belt of mountains, and is forced into a narrow canyon (the Waimakariri Gorge), before reverting to its braided form for its passage across the plains. It enters the Pacific north of Christchurch, near the town of Kaiapoi. Instead of being unoccupied Crown land as are most New Zealand river beds, the bed of the Waimakariri River is vested in the Canterbury Regional Council (Environment Canterbury). Name The name ''Waimakariri'' comes from the Māori words ''wai'', meaning ''water'', and ''makari ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rakaia River
The Rakaia River is in the Canterbury Plains in New Zealand's South Island. The Rakaia River is one of the largest braided rivers in New Zealand. The Rakaia River has a mean flow of and a mean annual seven-day low flow of . In the 1850s, European settlers named it the ''Cholmondeley River'', but this name lapsed into disuse. Description It rises in the Southern Alps, travelling in a generally easterly or southeasterly direction before entering the Pacific Ocean south of Christchurch. It forms a hapua as it reaches the ocean. For much of its journey, the river is braided river, braided, running through a wide shingle bed. Close to Mount Hutt, however, it is briefly confined to a narrow canyon known as the Rakaia Gorge. The Rakaia River is bridged in two places. The busiest crossing is at the small town of Rakaia, from the river mouth, where State Highway 1 (New Zealand), State Highway 1 using Rakaia Bridge and the South Island Main Trunk Railway cross the river using sepa ...

Canterbury Plains
The Canterbury Plains () are an area in New Zealand centred in the Mid Canterbury, to the south of the city of Christchurch in the Canterbury region. Their northern extremes are at the foot of the Hundalee Hills in the Hurunui District, and in the south they merge into the plains of North Otago beyond the Waitaki River. The smaller Amuri Plain forms a northern extension of the plains. Geology The Canterbury Plains were formed from Quaternary moraine gravels transported from the Southern Alps and deposited here during glacial periods in the late Pleistocene approximately 3 million to 10,000 years ago. The alluvial gravels were then reworked as shingle fans of several of the larger rivers, notably the Waimakariri, the Rakaia, the Selwyn / Waikirikiri, and the Rangitata. Part of the Canterbury-Otago tussock grasslands, the land is suitable for moderately intensive livestock farming but is prone to droughts, especially when the prevailing wind is from the northwest.

Southland, New Zealand
Southland ( mi, Murihiku) is New Zealand's southernmost region. It consists mainly of the southwestern portion of the South Island and Stewart Island/Rakiura. It includes Southland District, Gore District and the city of Invercargill. The region covers over 3.1 million hectares and spans over 3,400 km of coast. History The earliest inhabitants of Murihiku (meaning "the last joint of the tail") were Māori of the Waitaha iwi, followed later by Kāti Māmoe and Kāi Tahu. Waitaha sailed on the Uruao waka, whose captain Rakaihautū named sites and carved out lakes throughout the area. The Takitimu Mountains were formed by the overturned Kāi Tahu waka Tākitimu. Descendants created networks of customary food gathering sites, travelling seasonally as needed, to support permanent and semi-permanent settlements in coastal and inland regions. In later years, the coastline was a scene of early extended contact between Māori and Europeans, in this case sealers, whalers ...
