Everglades Pseudoatoll
The Everglades Pseudoatoll (also called a pseudo-atoll) was a major geomorphic feature of southern Florida during the Pliocene epoch. Origin The Everglades Pseudoatoll began its growth during the early Eocene as a paleodepression possibly created by an asteroid impact upon the carbonate Florida Platform at the southern part of what is now Everglades National Park. The pseudo-atoll is surrounded by a raised rim. Its growth as a reef system and pseudo-atoll began during the Oligocene reaching its maximum size of north to south during the Piacenzian of the late Pliocene. (Petuch, 163). Description The Everglades Pseudoatoll was a U-shaped asymmetrical system of reefs that surrounded the Okeechobean Sea, not unlike South Pacific atolls surrounded by a central lagoon. The west side was more developed than the east and south, as was the remainder of the west side. On the western side of this pseudo-atoll lay the Immokalee Reef Tract and chain of islands called the Immokalee Archipe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudo-atoll
A pseudo-atoll, like an atoll, is an island that encircles a lagoon, either partially or completely. A pseudo-atoll differs from an atoll as established by several authorities, such as how it is formed (not by subsidence, nor by coral). It is considered a preferable term to "near-atoll". There is a need for rigorous definition of "pseudo-atoll" before it can be accepted as a general term. Definitions Alexander Agassiz gave the term pseudo-atoll to "any ring-shaped reefs not formed as a result of subsidence". while Norman D. Newell and J. Keith Rigby called such reefs non-coral. and "We conclude that almost-atoll should be retained as a descriptive term as defined by Davis and Tayama, and that the use of "near-atoll" as a synonym be abandoned. The value of terms such as "semi-atoll" and "pseudo-atoll" needs close examination and more rigorous definition before being generally accepted." H. Mergner yet states that micro-atolls classify as pseudo-atolls. Professor David R. Stoddart of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scallop
Scallop () is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters. Scallops are a cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. The majority of species, however, live recumbent on sandy substrates, and when they sense the presence of a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nodipecten
''Nodipecten'' is a genus of large scallops, marine bivalve molluscs in the family Pectinidae, the scallops. These scallops often have attractive, strongly colored, thick shells. The generic name ''Nodipecten'' means "nodular scallop", because in this genus the shell is usually sculpted with regular, very large nodes. Species Species within the genus ''Nodipecten'' include: * ''Nodipecten arthriticus'' (Reeve, 1853) * ''Nodipecten fragosus'' (Conrad, 1849) * ''Nodipecten magnificus'' (Sowerby I, 1835) * ''Nodipecten nodosus'' (Linnaeus, 1758) — lion's paw scallop * ''Nodipecten subnodosus ''Nodipecten subnodosus'' is a species of scallop known by the common name giant lion's paw.

Mercenaria
''Mercenaria'' is a genus of edible saltwater clams, marine bivalve molluscs in the family Veneridae, the Venus clams. The genus ''Mercenaria'' includes the quahogs, consisting of ''Mercenaria mercenaria'', the northern quahog or hard clam, and ''M. campechiensis'', the southern quahog. These two species commonly hybridise where their ranges overlap. Mercenaria mercenaria is further subdivided in the marketplace and thence in the kitchen by size: the largest being the quahog or chowder clam, then smaller cherrystones, and smallest littlenecks; some markets also differentiate top necks which are intermediate in size between cherrystones and littlenecks. The smaller clams are eaten raw throughout New England, New York, and New Jersey; the larger clams are more suited for cooking. Other species within the genus include the venus clam ''M. stimpsoni'' found in north Pacific waters. All these species were formerly placed in the related genus ''Venus''.

Intertidal
The intertidal zone, also known as the foreshore, is the area above water level at low tide and underwater at high tide (in other words, the area within the tidal range). This area can include several types of Marine habitat, habitats with various species of Marine life, life, such as seastars, Sea urchin, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the ''littoral zone'' or ''shore, seashore'', although those can be defined as a wider region. The well-known area also includes steep rocky Cliff, cliffs, sandy Beach, beaches, Bog, bogs or wetlands (e.g., vast Mudflat, mudflats). The area can be a narrow strip, as in Pacific island, Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The peritidal zone is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in t ...

Mud Flat
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least of the Earth's surface. / They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes (or inland seas) alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. A recent global remote sensing analysis estimated that approximately 50% of the global extent of tidal flats occurs within eight countries (Indonesia, China, Austral ...

Kissimmee Embayment
Kissimmee ( ) is the largest city and county seat of Osceola County, Florida, United States. As of the 2020 census, the population was 79,226. It is a Principal City of the Orlando-Kissimmee-Sanford, Florida, Metropolitan Statistical Area, which had a 2010 population of 2,234,411. History This area was originally named Allendale, after Confederate Major J. H. Allen who operated the first cargo steamboat along the Kissimmee River—the ''Mary Belle''. It was renamed Kissimmee when incorporated as a city in 1883. The modern town, which is the county seat of Osceola County, was founded before the Civil War by the Bass, Johnson and Overstreet families. The etymology of the name Kissimmee is debated, apart from general agreement that it is Native American in origin. Its growth can be credited to Hamilton Disston of Philadelphia, who based his four-million acre (8,000 km2) drainage operation out of the small town. Disston had contracted with the financially wobbly state of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...
