Definitions &Translations Photic zone. The photic zone, euphotic zone, or sunlight zone is the depth of the water in a lake or ocean that is exposed to sufficient sunlight for photosynthesis to occur. It extends from the surface down to a depth where light intensity falls to one percent of that at the surface, called the euphotic depth.

Fracture zone A fracture zone is a linear oceanic feature—often hundreds, even thousands of kilometers long—resulting from the action of offset mid-ocean ridge axis segments. They are a consequence of plate tectonics. Lithospheric plates on either side of an active transform fault move in opposite directions; here, strike-slip activity occurs.

- According to Zone Therapy Practice, the body is divided into ten longitudinal zones, which provide a simple numbering sequence. Each toe defines a specific zone, therefore there are five zones per foot. Zone 1 is correlated with the big toe and the zones go to zone 5, which is correlated with the little toe.

Shakespeare Conspiracy Theory No-one suggests that someone else wrote Ben Jonson’s plays, and neither Ben Jonson nor any other of Shakespeare’s contemporaries suggested that their colleague, William Shakespeare, whom they knew well, did not write the plays performed in his name.

Biomes Intertidal Zone The intertidal zone is defined as the area between the high tide and low tide mark. Organisms that live in this zone have to deal with difficult environmental conditions, being both submerged in sea water and exposed to the air. They have to bear the great physical impact of waves, desiccation, and sunlight.

In Which Ocean Zone Do Dolphins Live? In which ocean zone do dolphins live? A: According to EnchantedLearning.com, dolphins live in what is known as the euphotic zone, which is sometimes referred to as the sunlit zone — part of the continental shelf that extends down to depths of anywhere from 50 to 660 feet. This zone is so named because it is lit by the sun for at least part of the day.

- Gulf of Mexico ‘dead zone’ predicted to measure nearly 7,000 square miles this summer. Phytoplankton blooms in the continental shelf on the coast of Texas and Louisiana. Scientists are estimating that there will once again be a large “dead zone” in the northern Gulf of Mexico this summer.

Littoral zone The littoral zone is the part of a sea, lake or river that is close to the shore. In coastal environments the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged.

Pelagic zone The pelagic zone can be thought of in terms of an imaginary cylinder or water column that goes from the surface of the sea almost to the bottom. Conditions differ deeper in the water column; the pressure increases, the temperature drops and less light penetrates.he pelagic zone can be contrasted with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the very bottom of the sea.

What is a dead zone? What is a dead zone? Hypoxic zones are areas in the ocean of such low oxygen concentration that animal life suffocates and dies, and as a result are sometimes called dead zones.. One of the largest dead zones forms in the Gulf of Mexico every spring. Each spring as farmers fertilize their lands preparing for crop season, rain washes fertilizer off the land and into streams and rivers.

What is the photic zone? the Photic zone of the ocean is the depth of water in a lake or  ocean exposed to sufficient sunlight for photosynthesis to occur.

What is the Photic Zone? Researchers are naturally interested in the photic zone since it can provide important information about ocean health. Protection of this zone is important for fisheries and other industries which use the ocean, and for the survival of the environment as a whole.

Definitions &Translations It also varies with seasonal changes in turbidity. Since the photic zone is where almost all of the primary productivity occurs, the depth of the photic zone is generally proportional to the level of primary productivity that occurs in that area of the ocean. About 90% of all marine life lives in the photic zone.

Aphotic zone The aphotic zone (aphotic from Greek prefix ἀ- + φῶς without light) is the portion of a lake or ocean where there is little or no sunlight.

Pelagic fish The epipelagic zone is the water from the surface of the sea down to 200 metres. It is also referred to as the surface waters or the sunlit zone, and includes the photic zone. The photic zone is defined as the surface waters down to the point where the sunlight has attenuated to 1% of the surface value.

Oceanic Zones Major zones in the oceans. Intertidal zone. The intertidal zone is the area of the seafloor between high tide and low tide. It bridges the gap between land and water. Tide pools, estuaries, mangrove swamps and rocky coastal areas are all part of the intertidal zone. Neritic zone. The water above the continental shelf is the neritic zone. Underwater forest of kelp and grassy meadows of sea grass are home to tiny fish, green turtles, sea cows, seahorses and tiny shrimp.

- The intertidal zone, also known as the littoral zone, in marine aquatic environments is the area of the foreshore and seabed that is exposed to the air at low tide and submerged at high tide, ie the area between tide marks. In the intertidal zone the most common organisms are small and most are relatively uncomplicated organisms.

Abyssal zone Layers of the pelagic zone. The abyssal zone or abyssopelagic is a layer of the pelagic zone of the ocean. Abyss derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,123 to 19,685 feet), this zone remains in perpetual darkness and never receives daylight.

Biomes Intertidal Zone. The intertidal zone is defined as the area between the high tide and low tide mark. Organisms that live in this zone have to deal with difficult environmental conditions, being both submerged in sea water and exposed to the air. They have to bear the great physical impact of waves, desiccation, and sunlight. Occasionally there are rains which saturate them in fresh water.

- The 1% light level also defines the euphotic zone of the lake, which is the layer from the surface down to the depth where light levels become too low for photosynthesizers. In most lakes, the sunlit euphotic zone occurs within the epilimnion. Figure 10.

Pelagic zone The pelagic zone can be contrasted with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the very bottom of the sea. It includes the sediment surface and some subsurface layers.Marine organisms living in this zone, such as clams and crabs, are called benthos.epending on the depth, the water column, rather like the Earth's atmosphere, can be divided into different layers. The pelagic zone occupies 1,330 million km 3 (320 million mi 3) with a mean depth of 3.68 km (2.29 mi) and maximum depth of 11 km (6.8 mi).
