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 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.
An underwater torch is available in the Education Edition of the Minecraft sandbox video game, created by combining a torch with magnesium on a crafting table. [7] Featured occasionally in the Sea Hunt television show. [8] Magnesium torches were used in the documentary series The Undersea World of Jacques Cousteau. "The Secrets of the Sunken ...
Deep underwater explosions are those where the crater is small in comparison with the depth of the explosion, [2] or nonexistent. The overall effect of an underwater explosion depends on depth, the size and nature of the explosive charge, and the presence, composition and distance of reflecting surfaces such as the seabed, surface, thermoclines ...
For this reason, scientists were astounded when they first found hydrothermal vents teeming with life in 1977. What was discovered was the ubiquitous symbiosis of chemoautotrophs living in (endosymbiosis) the vent animals' gills; the reason why multicellular life is capable to survive the toxicity of vent systems. Scientists are therefore now ...
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [1] The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.
"We've depleted all our resources," he said as fire hydrants across the region ran dry. "Those hydrants are typical for two or three fires, maybe one fire. And then you have something at this scale."
This region also contains a much higher concentration of nutrient salts, like nitrogen, phosphorus, and silica, due to the large amount of dead organic material that drifts down from the ocean zones above and decomposes. [3] The region below the abyssal zone is the sparsely inhabited hadal zone. [1] The region above is the bathyal zone. [1]
