Shell Beach (Western Australia)
Shell Beach is a beach in the Shark Bay region of Western Australia, located south-east of Denham. Situated on the northeastern side of the Taillefer Isthmus along the L'Haridon Bight, the beach is covered with shells for a stretch to a depth of . It is one of only two beaches in the world made entirely from shells. The beach was named because of the great abundance of the shells of the cockle species ''Fragum erugatum''. The seawater in the L'Haridon Bight has a high salinity due to both the geomorphology and local climate of the area. This high salinity has allowed the cockle to proliferate unchecked, since its natural predators have not adapted well to this environment. The shells have formed a limestone that is known as coquina. Before Shark Bay became a World Heritage Site, the coquina was mined and used for the construction of a number of buildings in Denham.

A226, Shark Bay Marine Park, Western Australia, Shell Beach, 2007
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey É‘. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Shark Bay, Western Australia
Shark Bay (Malgana: ''Gathaagudu'', "two waters") is a World Heritage Site in the Gascoyne region of Western Australia. The http://www.environment.gov.au/heritage/places/world/shark-bay area is located approximately north of Perth, on the westernmost point of the Australian continent. UNESCO's official listing of Shark Bay as a World Heritage Site reads: : History The record of Australian Aboriginal occupation of Shark Bay extends to years BP. At that time most of the area was dry land, rising sea levels flooding Shark Bay between BP and BP. A considerable number of aboriginal midden sites have been found, especially on Peron Peninsula and Dirk Hartog Island which provide evidence of some of the foods gathered from the waters and nearby land areas. An expedition led by Dirk Hartog happened upon the area in 1616, becoming the second group of Europeans known to have visited Australia. (The crew of the ''Duyfken'', under Willem Janszoon, had visited Cape York in 1606). T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. 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 total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616.

Taillefer Isthmus
The Taillefer Isthmus (French: ''Isthme Taillefer'') is an Australian isthmus linking Peron Peninsula to the coast of Western Australia in the Gascoyne region. Its western coast is formed by Henri Freycinet Harbour, its eastern one by L'Haridon Bight, both bodies of waters being part of Shark Bay. The isthmus is named after Hubert Jules Taillefer, a French physician who took part in the Baudin expedition to Australia. It was later traversed by Augustus Charles Gregory.

L'Haridon Bight
L'Haridon Bight is one of the bays on the eastern side of the Peron Peninsula in the Shark Bay World Heritage Site in the Gascoyne region of Western Australia. At its southern end lies Shell Beach, which is part of the very narrow Taillefer Isthmus that leads to the Peron Peninsula to the north. Its mouth at the north is just south west of Faure Island, where two points define its northern reach - Petit Point in the eastern part, and Dubaut Point to the west on the Peron Peninsula. It is one of locations in the Shark Bay where the water is hypersaline, and is also where a marine reserve exists.'12. Lharidon Bight Sanctuary Zone. Scale a. 1:350,000, in Western Australia.

Mollusc Shell
The mollusc (or molluskOften spelled mollusk shell in the USA; the spelling "mollusc" are preferred by ) shell is typically a calcareous exoskeleton which encloses, supports and protects the soft parts of an animal in the phylum Mollusca, which includes snails, clams, tusk shells, and several other classes. Not all shelled molluscs live in the sea; many live on the land and in freshwater. The ancestral mollusc is thought to have had a shell, but this has subsequently been lost or reduced on some families, such as the squid, octopus, and some smaller groups such as the caudofoveata and solenogastres. Today, over 100,000 living species bear a shell; there is some dispute as to whether these shell-bearing molluscs form a monophyletic group (conchifera) or whether shell-less molluscs are interleaved into their family tree. Malacology, the scientific study of molluscs as living organisms, has a branch devoted to the study of shells, and this is called conchology—although these te ...

Cockle (bivalve)
A cockle is an edible marine bivalve mollusc. Although many small edible bivalves are loosely called cockles, true cockles are species in the family Cardiidae. MolluscaBase eds. (2022). MolluscaBase. Cardiidae Lamarck, 1809. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=229 on 2022-02-09 True cockles live in sandy, sheltered beaches throughout the world. The distinctive rounded shells are bilaterally symmetrical, and are heart-shaped when viewed from the end. Numerous radial, evenly spaced ribs are a feature of the shell in most but not all genera (for an exception, see the genus ''Laevicardium'', the egg cockles, which have very smooth shells). The shell of a cockle is able to close completely (i.e., there is no "gap" at any point around the edge). Though the shell of a cockle may superficially resemble that of a scallop because of the ribs, cockles can be distinguished from scallops morphologically in that co ...

Fragum Erugatum
''Fragum erugatum'' is a small species of Cockle (bivalve), cockle, a marine Bivalvia, bivalve Mollusca, mollusc in the Family (biology), family Cardiidae. It is found in the shallow seas off the coast of Western Australia. It is commonly known as the Hamelin cockle, cardiid cockle or heart cockle. Taxonomy This species was first described by Ralph Tate in 1889 as ''Fragum erugatum''. More recently, it has been given several other names but these have since been synonymized with ''Fragum erugatum''. Some authorities now consider that it is sufficiently distinct from other members of the genus ''Fragum'' as to warrant being placed in a genus of its own as ''Microfragum erugatum''. Description ''Fragum erugatum'' is a small species of cockle growing to a length of about . The valves are dome-shaped, white and translucent. Distribution and habitat ''Fragum erugatum'' is native to warm shallow waters in Western Australia. Its range extends from the Dampier Archipelago to the Houtman ...

Seawater
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurement ...

Geomorphology
Geomorphology (from Ancient Greek: , ', "earth"; , ', "form"; and , ', "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography.
