Dark Ocean Floor

R lyeh is a fictional lost city that was first documented in the h.

Dark ocean floor.

Over 75 of the ocean floor lies can be found within this zone with the continental rise starting here. Until the development of sonar we knew very little about the ocean floor. Adaptation is the name of the game when you live thousands of feet below the water s surface. Only a small fraction of the seafloor has ever been mapped at high resolution.

R lyeh is a sunken city in the south pacific and the prison of the entity called cthulhu. See how these deep sea denizens make the most of their deep dark home. Lovecraft short story the call of cthulhu first published in weird tales in june 1928. The ocean is divided into three zones based on depth and light level.

Although some sea creatures depend on light to live others can do without it. Sunlight does not penetrate to the sea floor making these deep dark ecosystems less productive than those along the continental shelf. But despite their name these plains are not uniformly flat. Sunlight entering the water may travel about 1 000 meters 3 280 feet into the ocean under the right conditions but there is rarely any significant light beyond 200 meters 656 feet.

Your instinct was right. The lines you have pointed out are actually mapping anomalies. In 1977 scientists used submersible vehicles to explore the seabed and discovered vents gushing dark plumes of superhot mineral rich water. The deep ocean is dark very cold and has tremendous pressure from the overlying water.

This layer is also called the midnight or the dark zone. Scuba divers can explore only to about 40 meters while most submarines dive only to about 500 meters. Scientific research submersibles have explored the ocean s deepest trenches. Detailed maps require expensive specially equipped boats.

Join jessi and squeaks and learn all about the super cool super. At depths of over 10 000 feet and covering 70 of the ocean floor abyssal plains are the largest habitat on earth. Water entering cracks in the crust is heated by magma and mixed with mineral sulphides then belched forth in dark clouds.
