Sherlock River (Western Australia)
The Sherlock River is a river in the Pilbara region of Western Australia. It was named on 11 July 1861 by the surveyor and explorer Frank Gregory while on expedition in the area. The headwaters of the river rise from numerous springs on the Abydos Plain below the Mungaroona Range near the western edge of the Mungaroona Range Nature Reserve then flows in a northerly direction past the Chichester Range and then continuing north. The river crosses the North West Coastal Highway near Mount Fraser before discharging into Sherlock Bay and the Indian Ocean. The river forms a large estuary at the river mouth with an area of . Major pools exist along the length of the river, including Coonanarrinna Pool and Weedeemilegener Pool. The main riverbed is very wide and is mostly dry, with a minor ocean outlet from a large salt marsh estuarine area that contains small areas of mangrove A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water.

Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilbara
The Pilbara () is a large, dry, sparsely populated regions of Western Australia, region in the north of Western Australia. It is known for its Indigenous Australians, Aboriginal people; wealth disparity; its ancient landscapes; the prevailing red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). Geography The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,68 ...

Western Australia
Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a land area of , and is also the List of country subdivisions by area, second-largest subdivision of any country on Earth. Western Australia has a diverse range of climates, including tropical conditions in the Kimberley (Western Australia), Kimberley, deserts in the interior (including the Great Sandy Desert, Little Sandy Desert, Gibson Desert, and Great Victoria Desert) and a Mediterranean climate on the south-west and southern coastal areas. the state has 2.965 million inhabitants—10.9 percent of the national total. Over 90 percent of the state's population live in the South-West Land Division, south-west corner and around 80 percent live in the state capital Perth, leaving the remainder ...

Francis Thomas Gregory
Francis Thomas "Frank" Gregory (19 October 1821 – 23 October 1888) was an Australian explorer and politician. Born in England, he emigrated with his family to Australia as a boy. He was the younger brother of the explorer and politician Augustus Gregory, who also made his career in the colony. Biography Gregory was born at Farnsfield, Nottinghamshire, England in 1821. His family, including his older brother Augustus, emigrated to Western Australia in 1829. After getting a basic education, Gregory entered the Western Australian public service in 1841 as a cadet surveyor. In 1846, Gregory accompanied his older brother Augustus and explorer Henry Churchman, to investigate the country north of Perth. The following year, Gregory was appointed an assistant government surveyor; two years later he was promoted to staff surveyor in 1849. In 1857 he led expeditions to the upper Murchison River, and to country farther east and north in 1858. The next year Gregory visited England, to ...

Chichester Range
The Chichester Range is a range in the Pilbara region of Western Australia. The range rises abruptly from the coastal plain and is composed of rolling hills, escarpments, jagged peaks, gorges and winding tree-lined watercourses. The range is best described as an escarpment with a height of forming a tableland behind that slope gently to the south until it runs into the Hamersley Range. The steep escarpment is defined by a jumble of weathered basalts and granophyres. The highest point of the Chichester Range is Mount Herbert, with a height of . The peak takes about 45 minutes to climb and a car park is at the base of the peak. The peak is also on the route of the Chichester Range Camel trail, a tourist attraction that is operated on the range that finishes at Python's Pool. The range is part of the Millstream-Chichester National Park, along with Millstream station that is one of the few permanent watercourses in the area. Geologically the range is made up of a mixture of san ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North West Coastal Highway
North West Coastal Highway is a generally north–south Western Australian highway which links the coastal city of Geraldton with the town of Port Hedland. The road, constructed as a sealed two-lane single carriageway, travels through remote and largely arid landscapes. Carnarvon is the only large settlement on the highway, and is an oasis within the harsh surrounding environment. The entire highway is allocated National Route 1, part of Australia's Highway 1, and parts of the highway are included in tourist routes Batavia Coast Tourist Way and Cossack Tourist Way. Economically, North West Coastal Highway is an important link to the Mid West, Gascoyne and Pilbara regions, supporting the agricultural, pastoral, fishing, and tourism industries, as well as mining and offshore oil and gas production. In Geraldton, the highway begins at a grade separated interchange with Brand Highway and roads providing access to the port and town centre. Two major roads link the N ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Marsh
A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. ...

Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
