Parengarenga Harbour
Parengarenga Harbour is a natural harbour close to the northernmost point on the North Island of New Zealand. Located at the northern end of the Aupouri Peninsula, it extends inland for over 10 kilometres, almost severing the northern tip of the island from the rest of the peninsula. The harbour's mouth is towards the northern end of Great Exhibition Bay. The island's northernmost point, at the Surville Cliffs is only about 10 kilometres north of the harbour. Te Hāpua is a settlement at the western side of the harbour. History The harbour was an important location for the kauri gum digging trade in the latter 19th and early 20th centuries, as some of the highest quality kauri gum could be found around the harbour. The Parenga Gumfield Company was formed to harvest this resource. The white sand of Kokota Sandspit, at the southern head of Parengarenga Harbour, has provided a source of high purity silica sand for glassmaking. Dredging continued here until 1997. While smalle ...

Northland Region
The Northland Region ( mi, Te Tai Tokerau) is the northernmost of New Zealand's 16 local government regions. New Zealanders sometimes refer to it as the Winterless North because of its mild climate all throughout the year. The main population centre is the city of Whangārei, and the largest town is Kerikeri. At the 2018 New Zealand census, Northland recorded a population growth spurt of 18.1% since the previous 2013 census, placing it as the fastest growing region in New Zealand, ahead of other strong growth regions such as the Bay of Plenty (2nd with 15%) and Waikato (3rd with 13.5%). Geography The Northland Region occupies the northern 80% (265 km) of the 330 km Northland Peninsula, the southernmost part of which is in the Auckland Region. Stretching from a line at which the peninsula narrows to a width of just 15 km a little north of the town of Wellsford, Northland Region extends north to the tip of the Northland Peninsula, covering an area of 13,940&nb ...

Samuel Yates
Samuel Yates (May 10, 1919 in Savannah, Georgia – April 22, 1991 in New Brunswick, New Jersey) was a computer engineer and mathematician who first described unique primes in the 1980s. In 1984 he began the list of "Largest Known Primes" (today The Prime Pages) and coined the name titanic prime for any prime with 1,000 or more decimal digits. He also called those who proved their primality A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways ... "titans". He is the author of ''Repunits and Repetends''. Samuel Yatrofsky married May Berkowitz on April 5, 1941, in Brooklyn, NY, and along with his wife, brother and brother's wife, changed their surname from Yatrofsky to Yates on June 25, 1943, in Burlington County, New Jersey, due to anti-Semitism. He is buried in Beth Israel Jewish Cemetery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of The Northland Region
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Far North District
The Far North District is the northernmost territorial authority district of New Zealand, consisting of the northern part of the Northland Peninsula in the North Island. It stretches from North Cape and Cape Reinga / Te Rerenga Wairua in the north, down to the Bay of Islands, the Hokianga and the town of Kaikohe. The Far North District Council is based in Kaikohe, and has nine ward councillors representing three wards: Te Hiku (in the north), Kaikohe/Hokianga (in the west), Bay of Islands/Whangaroa (in the east). The council is led by the current mayor of Far North, Moko Tepania, who entered the role in 2022. Geography The Far North District is the largest of three territorial authorities making up the Northland Region. The district stretches from the capes and bays at the northern tip of the Aupouri Peninsula past Ninety Mile Beach to the main body of the Northland Peninsula, where it encompasses the Parengarenga Harbour, Whangaroa Harbour and Bay of Islands (on the e ...

Pilot Whale
Pilot whales are cetaceans belonging to the genus ''Globicephala''. The two extant species are the long-finned pilot whale (''G. melas'') and the short-finned pilot whale (''G. macrorhynchus''). The two are not readily distinguishable at sea, and analysis of the skulls is the best way to distinguish between the species. Between the two species, they range nearly worldwide, with long-finned pilot whales living in colder waters and short-finned pilot whales living in tropical and subtropical waters. Pilot whales are among the largest of the oceanic dolphins, exceeded in size only by the orca. They and other large members of the dolphin family are also known as blackfish. Pilot whales feed primarily on squid, but will also hunt large demersal fish such as cod and turbot. They are highly social and may remain with their birth pod throughout their lifetime. Short-finned pilot whales are one of the few mammal species in which females go through menopause, and postreproductive females ...

Killer Whale
The orca or killer whale (''Orcinus orca'') is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is the only extant species in the genus ''Orcinus'' and is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas. Orcas have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack baleen whale calves, and even adult whales. Orcas are apex predators, as they have no natural predators. They are highly social; some populations are composed of very stable matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolphin
A dolphin is an aquatic mammal within the infraorder Cetacea. Dolphin species belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species named as dolphins. Dolphins range in size from the and Maui's dolphin to the and orca. Various species of dolphins exhibit sexual dimorphism where the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers. Though not quite as flexible as seals, some dolphins can briefly travel at speeds of per hour or leap about . Dolphins use their conical teeth to capture fast-moving prey. They have well-developed hearing which is adapted for both air and water. It is so well developed that some can survive even if they are blind. Some species are well adapted for diving to great depths. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Sea Turtle
The green sea turtle (''Chelonia mydas''), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus ''Chelonia''. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of ''C. mydas'' is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, ''C. mydas'' is mostly herbivorous. The adults usually inhabit shallow lagoons, feeding mostly on various ...

Ngāwini Yates
Ngāwini Yates (1852–1853 – 19 July 1910) was a part-Māori New Zealander, who was a storekeeper, farmer and businesswoman in the Northland Peninsula, far north of New Zealand in the later part of the 19th century. Early life Ngāwini Yates, also known as Annie, was born Ngāwini Murray around 1852 or 1853 at Pukepoto, near Kaitaia, in the far north of New Zealand. She was the oldest of 15 children born to John Murray, a shipwright who had settled at Pukepoto having immigrated from Europe. Her mother, Kateraina Te Kone, was a Māori of the Te Rarawa ''iwi'' (tribe) who also had connections to the Te Aupōuri ''iwi''. Commercial activity In December 1880, at Taipa-Mangonui, Mangonui, she married Samuel Yates (storekeeper), Samuel Yates, a storekeeper who had his premises in the town and a store at Parengarenga Harbour, Pārengarenga Harbour, close to North Cape (Otou), North Cape.

Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an Insulator (electricity), electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination geometry, tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Kauri Gum
Kauri gum is resin from kauri trees (''Agathis australis''), which historically had several important industrial uses. It can also be used to make crafts such as jewellery. Kauri forests once covered much of the North Island of New Zealand, before the arrival of people caused deforestation, causing several areas to revert to sand dunes, scrubs, and swamps. Even afterwards, ancient kauri fields continued to provide a source for the gum and the remaining forests.Hayward, pp 4–5 Kauri gum forms when resin from kauri trees leaks out through fractures or cracks in the bark, hardening with the exposure to air. Lumps commonly fall to the ground and can be covered with soil and forest litter, eventually fossilising. Other lumps form as branches forked or trees are damaged, releasing the resin.Hayward, p 2 Uses The Māori had many uses for the gum, which they called ''kapia''. Fresh gum was used as a type of chewing gum (older gum was softened by soaking and mixing with juice of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
