Whangateau Harbour
The Whangateau Harbour is a natural harbour in New Zealand. It is a sandspit estuary, located on the north-eastern coast of the Auckland Region north-east of Matakana, and empties into the Hauraki Gulf. Due to the harbour's high quality water and dense shellfish beds (primarily Paphies australis, pipi), the harbour is a popular spot for shellfish gathering. Geography The Whangateau Harbour is a sandspit estuary, separated from Ōmaha Bay by a sandspit, where the town of Ōmaha is located. The modern harbour formed during the Holocene, after the formation of the sandspit. Horseshoe Island is an exposed sand-bar located in the centre of the harbour. The Whangateau Harbour has almost complete tidal flushing, meaning it has some of the best water quality for a harbour in New Zealand. Flora and fauna The harbour has a wide range of intertidal and subtidal reefs, supporting a wide range of benthic wildlife. High numbers of ''Scutus breviculus'', octopuses and Australostichopu ...

Warkworth, New Zealand
Warkworth () is a town on the Northland Peninsula in the upper North Island of New Zealand. It is in the northern part of the Auckland Region, north of Auckland and south of Whangārei, at the head of Mahurangi Harbour. State Highway 1 (New Zealand), State Highway 1 runs past it. Mahurangi Harbour and surrounding area has been settled by Māori people, Māori since at least the 13th century. As Warkworth is the uppermost navigable point on the Mahurangi River, it was a crossroads between overland traffic and waka (canoe), waka, and gained the name , referring to the waterfalls on the river. Māori people of the Mahurangi Harbour area moved seasonally between different kāinga based on available resources, and came to the dense Agathis australis, kauri forests at Puhinui for food resources such as berries and eels, and to fell trees to build waka. During the 17th and 18th centuries, Ngāti Rongo, Ngāti Raupō and Ngāti Manuhiri were active in the Warkworth area. The area was ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of Silicon dioxide, SiO2. Quartz is, therefore, classified structurally as a Silicate mineral#Tectosilicates, framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longshore Drift
Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle, shells) along a coast parallel to the shoreline, which is dependent on the angle of incoming wave direction. Oblique incoming wind squeezes water along the coast, generating a water current that moves parallel to the coast. Longshore drift is simply the sediment moved by the longshore current. This current and sediment movement occurs within the surf zone. The process is also known as littoral drift. Beach sand is also moved on such oblique wind days, due to the swash and backwash of water on the beach. Breaking surf sends water up the coast (swash) at an oblique angle and gravity then drains the water straight downslope (backwash) perpendicular to the shoreline. Thus beach sand can move downbeach in a sawtooth fashion many tens of meters (yards) per day. This process is called "beach drift", but some workers regard it as sim ...

Spinifex (coastal Grass)
''Spinifex'' is a genus of perennial coastal plants in the Poaceae, grass family. They are one of the most common plants that grow in sand dunes along the coasts of Africa, Middle East, Asia, Australia, New Zealand, and New Caledonia, with the ranges of some species extending north and west along the coasts of Asia as far as India and Japan. As they help stabilise the sand, these grasses are an important part of the entire sand dune ecosystem. The single species indigenous to New Zealand, ''Spinifex sericeus'', is also found in Australia. Confusingly, the word "spinifex" is also used as a common name referring to grasses in the related genus ''Triodia (plant), Triodia''. ''Triodia'' however is native to inland Australia and refers to a group of spiny-leaved, tussock grass, tussock-forming grasses. Species Species include: * Spinifex × alterniflorus, ''Spinifex'' × ''alterniflorus'' Nees – Western Australia * ''Spinifex hirsutus'' Labill. – all 6 states of Australi ...

Omaha Beach Vista
Omaha ( ) is the most populous city in the U.S. state of Nebraska. It is located in the Midwestern United States along the Missouri River, about north of the mouth of the Platte River. The nation's 41st-most-populous city, Omaha had a population of 486,051 at the 2020 census. The eight-county Omaha–Council Bluffs metropolitan area, which extends into Iowa, has approximately 1 million residents and is the 55th-largest metro area in the United States. Omaha is the county seat of Douglas County. Omaha's pioneer period began in 1854, when the city was founded by speculators from neighboring Council Bluffs, Iowa. The city was founded along the Missouri River, and a crossing called Lone Tree Ferry earned the city its nickname, the "Gateway to the West". Omaha introduced this new West to the world in 1898, when it played host to the World's Fair, dubbed the Trans-Mississippi Exposition. During the 19th century, Omaha's central location in the United States spurred the city to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
