Waituna
A waituna is a freshwater coastal lagoon on a mixed sand and gravel (MSG) beach, formed where a braided river meets a coastline affected by longshore drift. This type of waterbody is neither a true lake, lagoon nor estuary. This classification differentiates it from hapua, a type of river mouth lagoon. Both waituna and hapua are rare globally but common in New Zealand, where they are considered ecologically significant as sites of traditional Māori people, Maori food-gathering as well as for their diversity of fish and bird species. Waitnua form an interlinked chain of habitats which run the length of the east coast of the South Island: from Wairua Lagoon and Lake Grassmere in Marlborough District, Marlborough, through Lake Ellesmere, Te Waihore / Lake Ellesmere and Coopers Lagoon / Muriwai, Coopers Lagoon in central Canterbury Region, Canterbury, and Washdyke Lagoon and Wainono Lagoon in South Canterbury, to Waituna Lagoon in Southland District, Southland.

Waituna Lagoon
__NOTOC__ The Waituna Lagoon is on the southern coastline of the South Island of New Zealand. It forms part of the Awarua Wetland, a Ramsar site that was established in 1976. It gives it name to waituna, a type of ephemeral coastal lake. The lagoon is an important habitat for resident and migratory birds with seventy three different species being recorded. The expansion in the area of ''Leptocarpus (plant), Leptocarpus'' rushes that has been observed over a 47-year period in the lagoon have been attributed to artificial openings of the lagoon to the sea, and the increase in sedimentation. The lagoon is largely unmodified by human activity but there are elevated nutrient levels and sedimentation with a fear that it may lead to eutrophication. Recreational use Waituna Lagoon is a common fishing and game bird hunting spot. There is a good supply of brown trout in the lake/lagoon and its tributaries with a daily limit of two trout per person per day. The fishing season runs from 1 ...

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 ...

Coopers Lagoon / Muriwai
Coopers Lagoon / Muriwai is a small coastal waituna-type lagoon in the Canterbury region of New Zealand, located approximately half way between the mouth of the Rakaia River and the outlet of the much larger Lake Ellesmere / Te Waihora. While the present-day lagoon is separated from the nearby Canterbury Bight by approximately , the water of the lagoon is considered brackish and early survey maps show that, until recently, the lagoon was connected to the ocean by a small channel. The lagoon, along with the surrounding wetlands, has historically been an important ''mahinga kai'' (site of traditional significance for food and other natural resources) for local Māori. In 1998, Coopers Lagoon was officially given a dual place name as part of a Treaty of Waitangi settlement with Ngāi Tahu, receiving the name Coopers Lagoon / Muriwai. Ecology Coopers Lagoon / Muriwai is recognised as a nationally significant habitat for birdlife, forming part of a chain of waituna and extending a ...

Lake Ellesmere
Lake Ellesmere / Te Waihora is a broad, shallow coastal lake or waituna, in the 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 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 bar-type waterbody, commonly called a lake or lagoon. It covers an area of , and is New Zealand's 5th largest lake (by area). Waituna and river mouth lagoons, or hapua, form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Grassmere
Lake Grassmere / Kapara Te Hau is a New Zealand waituna-type lagoon in the northeastern South Island, close to Cook Strait. The lake is used for the production of salt. Geography Lake Grassmere, south of Blenheim and south of the mouth of the Awatere River, is a shallow lagoon protected from the open sea by a single barrier beach covered by sand dunes. It is on the north-easterly extension of the Ward depression. Covering an area of , it has no natural inflow and is prone to strong warm winds. Close to the sea, it also has a very high salinity. Because of these geographical characteristics, it is ideal for natural salt extraction. Grassmere has been divided into solar evaporation ponds. Seawater is pumped in, and moved between ponds over several months, increasing in salinity with each successive evaporation period. As salinity increases, crystallised salt forms and is extracted. Grassmere's area varies between ; this maximum is attained only in rare floods. The waters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephemeral
Ephemerality (from the Greek word , meaning 'lasting only one day') is the concept of things being transitory, existing only briefly. Academically, the term ephemeral constitutionally describes a diverse assortment of things and experiences, from digital media to types of streams. "There is no single definition of ephemerality". With respect to unique performances, for example, it has been noted that " hemerality is a quality caused by the ebb and flow of the crowd's concentration on the performance and a reflection of the nostalgic character of specific performances". Because different people may value the passage of time differently, ephemerality may be a relative, perceptual concept: "In brief, what is short-lived may not be the object itself, but the attention we afford it".Ronald Beiner, ''Political Philosophy: What It Is and Why It Matters'' (2014), p. 10. Ephemerality and nature Geographical features An ephemeral stream is that which only exists following precipitation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ngai Tahu
Ngai (also called Múrungu or Enkai) is the monolithic Supreme God in the spirituality of the Kikuyu (or Gikuyu) and the closely related Embu, Meru and Kamba groups of Kenya, and the Maasai of Kenya and Tanzania. Ngai is creator of the universe and all in it. Regarded as the omnipotent God,Middleton, John; Kershaw, Greet ; ''The Kikuyu and Kamba of Kenya: East Central Africa, Part 5,'' Routledge (reprint, 2017), p. 128,(Retrieved 5 April 2019) the Kikuyu, Embu, Meru, Kamba and the Maasai of Kenya worshiped Ngai facing the Mt. Kirinyaga (Mount Kenya) while prayers and goat sacrificial rituals were performed under the sacred Mugumo tree (a fig tree species). Occasions which may warrant sacrifice or libation include times of drought; epidemics; during planting and harvesting; and human life stages such as birth, marriage and death. Ngai in Kikuyu, Embu, Meru and Kamba Worship Ngai was often referred to as "Mwene Nyaga", meaning "Owner of the Dazzling Light". Kenyan anthropologist, ...

Canterbury Bight
The Canterbury Bight is a large bight on the eastern side of New Zealand's South Island. The bight runs for approximately from the southern end of Banks Peninsula to the settlement of Timaru and faces southeast, exposing it to high-energy storm waves originating in the Pacific Ocean. The bight is known for rough conditions as a result, with wave heights of over common. Much of the bight's geography is shaped by this high-energy environment interacting with multiple large rivers which enter the Pacific in the bight, such as the Rakaia, Ashburton / Hakatere, and Rangitata Rivers. Sediment from these rivers, predominantly Greywacke, is deposited along the coast and extends up to out to sea from the current shoreline. Multiple '' hapua'', or river-mouth lagoons, can be found along the length of the bight where waves have deposited sufficient sediment to form a barrier across a river mouth, including most notably Lake Ellesmere / Te Waihora and Washdyke Lagoon Zones of the Canterbur ...
