Lake Rerewhakaaitu
Lake Rerewhakaaitu is a small, shallow lake in northern New Zealand, located 30 kilometres to the east of Rotorua. It is immediately south of the active volcano Mount Tarawera, and the geography was substantially altered by the 1886 eruption of Mount Tarawera. Geography At a mean autumn height of above sea level the lake is highest and southernmost of the Rotorua Te Arawa lakes. Occupying a shallow basin, it is mostly surrounded by farming pasture; although over the past few decades, exotic and indigenous forest cover has begun to appear. Water Flow The lake is feed by the Awaroa and Mangakino Streams. The lake has no permanent outflow, as it is above the water table of much of the surrounding land ( by perhaps up to except at north-eastern side), but has an artificial overflow channel to the south east to control the maximum height. Also, when the lake is high, water can flow down the Mangaharakeke Stream due to these water table issues. Further the Awaroa Stream is ephemer ...

Mount Tarawera
Mount Tarawera is a volcano on the North Island of New Zealand within the older but volcanically productive Ōkataina Caldera. Located 24 kilometres southeast of Rotorua, it consists of a series of rhyolitic lava domes that were fissured down the middle by an explosive basaltic eruption in 1886. This eruption was one of New Zealand's largest historical eruptions, and killed an estimated 120 people. The fissures run for about northeast-southwest. The volcano's component domes include Ruawahia Dome (the highest at 1,111 metres), Tarawera Dome and Wahanga Dome. It is surrounded by several lakes, most of which were created or drastically altered by the 1886 eruption. These lakes include Lakes Tarawera, Rotomahana, Rerewhakaaitu, Ōkataina, Ōkareka, Tikitapu / Blue and Rotokākahi / Green. The Tarawera River runs northeastwards across the northern flank of the mountain from Lake Tarawera. In 2000, the mountain was ceded to the Ngāti Rangitihi sub-tribe of Te Araw ...

Whakamaru Caldera
The Whakamaru Caldera which was created in a massive eruption with a VEI of 8 is approximately in size and is located in the North Island of New Zealand. It now contains active geothermal areas as well as the later Maroa Caldera. Geography The Whakamaru Caldera covers an area larger than the younger Taupō Volcano to its south and indeed the rims overlap. To its north the more recent eruptive centres have sometimes been grouped as the Mokai Ring Complex or Maroa Volcanic Centre. It contains to its north east the more recently active Maroa Caldera with the Ben Lomond Dome being outside the southern border of the Maroa Caldera but definitely a feature of the Whakamaru Caldera. Domes within the caldera include the Western Dome Complex, including Pokuru which defines its north western borders (which likely overlap with those of the older Mangakino caldera complex), Forest Road Dome, Puketarata (which is the last Maroa Caldera eruption at 14,000 years ago), Ngangiho which is ...

Rotorua Lakes District
Rotorua Lakes District or Rotorua District is a Territorial authorities of New Zealand, territorial authority district in the North Island of New Zealand. It has one urban area of significant size, the city of Rotorua. The district is governed by Rotorua Lakes Council, which is headquartered in Rotorua and is headed by a mayor. The district falls within two Regions of New Zealand, regional council areas, with the majority of the area and Rotorua city in the Bay of Plenty region and the rest in the Waikato region. Tania Tapsell has been the mayor of Rotorua since the 2022 local elections. History Rotorua has an unusual history as the town was built by the Government as a tourist destination in the 1880s. Through the Rotorua Borough Act 1922, which achieved royal assent on 28 September 1922, the Rotorua Borough was formed. The inaugural elections for mayor were held in February 1923 and Cecil Clinkard was successful. In 1962, Rotorua was proclaimed a city. In 1979, the status was c ...

Ministry Of Education (New Zealand)
The Ministry of Education (Māori: ''Te Tāhuhu o te Mātauranga'') is the public service department of New Zealand charged with overseeing the New Zealand education system. The Ministry was formed in 1989 when the former, all-encompassing Department of Education was broken up into six separate agencies. History The Ministry was established as a result of the Picot task force set up by the Labour government in July 1987 to review the New Zealand education system. The members were Brian Picot, a businessman, Peter Ramsay, an associate professor of education at the University of Waikato, Margaret Rosemergy, a senior lecturer at the Wellington College of Education, Whetumarama Wereta, a social researcher at the Department of Maori Affairs and Colin Wise, another businessman. The task force was assisted by staff from the Treasury and the State Services Commission (SSC), who may have applied pressure on the task force to move towards eventually privatizing education, as had ...

Trophic Level Index
The trophic level index (TLI) is used in New Zealand as a measure of nutrient status of lakes. It is similar to the trophic state index but was proposed as alternative that suited New Zealand. The system uses four criteria, phosphorus and nitrogen concentrations, as well as visual clarity and algal biomass weighted equally.

Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called "steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent except ...

Double-banded Plover
The double-banded plover (''Charadrius bicinctus''), known as the banded dotterel or pohowera in New Zealand, is a species of bird in the plover family. Two subspecies are recognised: the nominate ''Charadrius bicinctus bicinctus'', which breeds throughout New Zealand, including the Chatham Islands, and ''Charadrius bicinctus exilis'', which breeds in New Zealand's subantarctic Auckland Islands. Taxonomy A 2015 study found its closest relatives to be two other plovers found in New Zealand, the New Zealand dotterel (''Charadrius obscurus'', also called the New Zealand plover) and the wrybill (''Anarhynchus frontalis'', which the study found to be in the ''Charadrius'' clade). Description The double-banded plover is distinguished by a dark, grey-brown back with a distinctive white chest and a thin band of black situated just below the neck running across the chest along with a larger brown band underneath. During breeding season, these bands are more dominantly shown on the males ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tephra
Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism. Volcanologists also refer to airborne fragments as pyroclasts. Once clasts have fallen to the ground, they remain as tephra unless hot enough to fuse into pyroclastic rock or tuff. Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. When a volcano explodes, it releases a variety of tephra including ash, cinders, and blocks. These layers settle on the land and, over time, sedimentation occurs incorporating these tephra layers into the geologic record. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer. These fossils are later dated by scientists to determine the age of the fossil and its place within the geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ignimbrite
Ignimbrite is a type of volcanic rock, consisting of hardened tuff. Ignimbrites form from the deposits of pyroclastic flows, which are a hot suspension of particles and gases flowing rapidly from a volcano, driven by being denser than the surrounding atmosphere. New Zealand geologist Patrick Marshall (1869-1950) coined the term ''ignimbrite'' from the Latin ''igni-'' [fire] and ''imbri-'' [rain]. Ignimbrites are made of a very poorly sorted mixture of volcanic ash (or tuff when Lithification, lithified) and pumice lapilli, commonly with scattered lithic fragments. The ash is composed of glass shards and crystal fragments. Ignimbrites may be loose and unconsolidated, or lithified (solidified) rock called lapilli-tuff. Near the volcanic source, ignimbrites often contain thick accumulations of lithic blocks, and distally, many show meter-thick accumulations of rounded cobbles of pumice. Ignimbrites may be white, grey, pink, beige, brown, or black depending on their composition and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
