Pelagic zones. The ocean can be conceptualized as being divided into various zones, depending on depth, and presence or absence of sunlight.Nearly all life forms in the ocean depend on the photosynthetic activities of phytoplankton and other marine plants to convert carbon dioxide into organic carbon, which is the basic building block of organic matter.
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches.The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions.
The Secret Reef, the largest tank in Ocean Journey (and the Tennessee Aquarium), containing 618,000 US gallons (2,340,000 L). It depicts the environment of the Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico and can be viewed from three levels including the Undersea Cavern, an underwater walk-through feature.
Every adaptation that Bathydevius has developed to live in the midnight zone, classified as the deep waters that exist between 3,300 feet (1,000 meters) and 13,100 feet (4,000 meters) below the ...
Below this zone, the deep sea consists of the abyssal zone which occurs between the ocean depths of 3000 and 6000 meters [14] and the hadal zone (6000 – 11,000 meters). [ 15 ] [ 16 ] Food consists of falling organic matter known as ' marine snow ' and carcasses derived from the productive zone above, and is scarce both in terms of spatial and ...
Environments in which subsurface life has been found [1]. The deep biosphere is the part of the biosphere that resides below the first few meters of the ocean's surface. It extends 10 kilometers below the continental surface and 21 kilometers below the sea surface, at temperatures that may reach beyond 120 °C (248 °F) [2] which is comparable to the maximum temperature where a metabolically ...
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries. It is a branch of marine biology and botany.
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
