Topic: Neritic zone


In the News (Thu 16 Feb 12)

  
  Neritic zone - Wikipedia, the free encyclopedia
The neritic zone spans from the low-tide line to the edge of the continental shelf in oceans.
The neritic zone has a low water pressure and fairly stable temperature and is a home to most of the world's great fishing areas.
The neritic zone is the continental shelf after the Intertidal zone to the continental cliff, where the continental crust ends and the oceanic crust begins.

The final area of the littoral zone is the subtidal zone, which is always covered by seawater, and extends into the neritic zone.
The neritic zone is the nearshore ocean environment, that which occurs above the continental shelf and is often called the coastal waters.
The benthic zone extends from the intertidal, to the continental shelf, to the continental slope, to the deep ocean floor.

Plants and animals that live in the ocean are influenced by sunlight, distance from the shore, the water depth, salinity, and temperature, type of bottom sediments and dissolved oxygen.
Euphotic zone is the portion of the photic zone near the surface where light is bright enough for photosynthesis to occur.
The abyssal zone is a subdivision of the benthic zone and is characterized by extremely high pressures, consistently low temperatures, low oxygen, few nutrients and no sunlight.

The bottom of the ocean is known as the benthic zone, while the pelagic zone extends from the ocean floor to the surface.
The neritic zone is that part of the pelagic zone which extends from the high tide line to the ocean bottom less than 200 m deep while water deeper than 200 m feet is referred to as the oceanic zone.
The next zone is the midlittoral zone, which includes the majority of the intertidal zone and recieves periodic exposure and submersion by tides.

All parts of the intertidal zone, all parts of the neritic zone and the upper part of the oceanic zone get sunlight and are therefore part of the photic zone.
In the neritic and oceanic zones, the bottom is called the benthic zone while the water itself is called the pelagic zone.
Neritic zones in New England have more nutrients in the water than places like Florida because the change of seasons causes the water to change temperature.

The fauna of this zone may be termed the mesobenthos; it is not so abundant, nor so sharply characterized, as the epibenthos, and yet is sufficiently distinct to deserve at any rate a provisional name.
The horizontal barriers to the neritic plankton are practically those mentioned as governing the epibenthos; indeed, it would seem that the distribution of hemibenthic adults is determined by that of their more delicate larvae.
In the neritic epiplankton of polar waters the larvae of hemibenthic forms are almost absent; indeed, the development of cold-water benthos, whether shallow or abyssal, appears to be in most cases direct, this is, without a larval metamorphosis.

Within the photic zone, the shallow area found close to shore is designated as the littoral zone, the surface water away from the shore is referred to as the limnetic zone.
The photic zone (depths which receive sufficient light to support photosynthesis) consists of the intertidal zone (exposed to air when the tide changes), the neritic zone (water less than 300 meters deep) and the oceanic zone.
Organisms living in the abyssal zone (usually considered to be at depths greater than 12,000 ft or 4,000 m) are adapted to extremely cold temperatures and high pressures.

In examining the relationship between organisms and their physical environment, one easy place to begin is to separate those organisms that live in the water column from those living on the sea bed.
The neritic zone is the shallow water on the continental shelf.
Shelves may be less than 200 km deep, so large portions or all of the neritic zone may be within the photic zone (the depth of light penetration for photosynthesis).

Tides uncover parts of this zone and the area uncovered is the intertidal zone, above is the supratidal zone, affected by salt spray but not covered by sea water and below the intertidal zone is the subtidal zone..submerged and extending seaward.
Other zones include the surface waters of the coastal areas called the neritic zone and the waters of the ocean called the epipelagic zone.The open ocean is less productive than the neritic zone which contains plant plankton, fish larva, invertebrate larva that will eventually end up near the coast.
The open ocean is divided into zones depending on the amount of light it receives...from the epipelagic layer to the mesopelagic zone 200-1000m in which daytime inhabitants migrate upwards during the night, bringing back nutrients and some exhibit bioluminescence (light producing organs called photophores).

The neritic zone is the first 200 meters (656 feet) of ocean water, which includes the seashore and most of the continental shelf.
Although fish are found everywhere in the ocean, the abundance of small organisms in the neritic zone provides a plentiful source of food for larger animals.
The oceanic zone extends from 200 meters (656 feet) deep all the way down to the bottom of the ocean, which can be thousands of meters deep.

Littoral fringe: This zone extends higher than the highest tide where there is great exposure with spray from the various waves causing the organisms to extend higher into the littoral zone; lichens and algae enclosed in a gelatinous sheath form the vegetation; snails feed on these vegetation.
Littoral zone: it is covered and uncovered by daily tides; Upper subzone: barnacles on the upper limit, Midlittoral subzone: oyster, mussels and limpet; brown algae Lower subzone: blue mussels, young starfish, sea urchins, brittle stars and bryozoans; red algae and Irish moss.

The three major oceanic habitats are (1) the neritic zone-shallow zones along the continental coasts with a large number of species; (2) the surface zone-upper layers of the open sea with diverse species; and (3) the abyssal zone-deep-water areas shown to have more diversity than was thought as sampling techniques have improved.
The abyssal zone would appear to be quite inhospitable, with its intense pressure, low temperature, and complete lack of light (and therefore photosynthesis).
The three zones are (1) littoral zone-shallow water along the edges; (2) limnetic zone-upper layer of open water; and (3) profundal zone-water below the limit of light penetration.

Neritic zone: The continental shelf extends out pretty far before dropping off to the really deep ocean —; that part after the beach but before the drop-off is called the neritic zone.
Aphotic means "no light," so the aphotic zone is where light does not penetrate, which is in the deepest part of the ocean.
That means (B), the aphotic zone, is the correct answer.

The open water environment is the pelagic zone, and the seafloor environment is the benthic zone.
The pelagic zone is divided into the coastal or neritic zone above the continental shelf and the oceanic zone or deep water away from the influence of land; since the upper Adriatic Sea hardly is anything deeper than 50m, it is considered to belong to the coastal or neritic zone.
As a result of convergence zones and boundaries between water types, zooplankton exists in patches of high population density between areas that are less heavily populated.

The horizontal zones that extend from the shore are the littoral or intertidal zone, the sublittoral or neritic zone, and the pelagic or open water zone.
The vertical regions that extend downward from the intertidal zone are the benthic region, the continental slope or bathyl region, the deep-sea floor or abyssal plain, and the deep ocean trenches or hadal region.
Conversely, the ocean zones are not as highly productive except for the pleuston layer where there is adequate light for bacteria that are primary producers.
