Almost three-quarters of our planet is covered by water. 90 percent of the expanse of water is spread out amongst the three large oceans – the Pacific Ocean, the Atlantic Ocean and the Indian Ocean. Additionally, there are a number of semi-enclosed seas. Depending on where they are located, one speaks of a Mediterranean, an inland or a marginal sea. The deepest spot at just over 37,500 feet is situated in the Mariana Trench in the western Pacific. The offshore biosphere is divided into pelagic zones. The topmost zone, the epipelagic, reaches up to 200 metres. The largest biodiversity of animal and plant species are found there because this living environment is still flooded with sufficient light, moderate temperatures, and enough water pressure, making it still relatively friendly to life forms. The area between 650 and 3,250 feet is called mesopelagic. This part only has sparse blue light and is already regarded as the deep-sea. In the bathypelagic zone (3,250 feet to 13,000 feet) there is a 400 bar pressure which equates to 400 times higher than on the ocean surface. The zone from 13,000 feet to 19,500 feet is referred to as abyssopelagic. The last zone, the hadopelagic, is the deepest section and reaches 35,750 feet. Although the water pressure already amounts to 1100 bar and the temperatures are close to freezing, living organisms exist here as well.
