With positive buoyancy (e.g. floating fruit), ocean surface currents freely move propagules, and dispersal distances are only limited by the viability time of the fruit, [55] [56] leading to exceptionally long single dispersal events (more than 100 km), [57] which is rare for passive abiotic movement of terrestrial fruit and seeds.
The SOFAR channel (short for sound fixing and ranging channel), or deep sound channel (DSC), [1] is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating.
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 ...
A summary of the path of the thermohaline circulation. Blue paths represent deep-water currents, while red paths represent surface currents. Thermohaline circulation. Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes.
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
To save money and conserve energy during the summer, many homeowners turn down the thermostat on their hot water heaters. The trick is, in the winter, you have to remember to turn it back up.
The company behind a search for pilot Amelia Earhart's possible crash site in the Pacific said a sonar image believed to resemble her plane turned out to be the sea floor's normal shapes.
The novel describes the course of an attack on humanity by creatures from the ocean depths, as told through the eyes of two characters: Mike Watson, a journalist for the English Broadcasting Company (EBC) with his wife and colleague Phyllis; and Professor Alastair Bocker, who is more clear-minded and far-sighted about the developing crisis than everybody else but who often alienates people by ...
