Silicon enters the ocean in a dissolved form such as silicic acid or silicate. [103] Since diatoms are one of the main users of these forms of silicon, they contribute greatly to the concentration of silicon throughout the ocean. Silicon forms a nutrient-like profile in the ocean due to the diatom productivity in shallow depths. [103]
The Water Horse was formerly scheduled for two different release dates in North America: 21 September 2007 and 7 December 2007. [ 12 ] [ 13 ] No reason has been given as to why either date was dropped, but the film was released across 2,772 screens [ 14 ] in the United States, Canada and Mexico on Christmas Day of 2007.

In the deep ocean, another 26.2 Tmol Si Year −1 is dissolved before being deposited to the sediments as opal silica. [20] At the sediment water interface, over 90% of the silica is recycled and upwelled for use again in the photic zone. [20] Biogenic silica production in the photic zone is estimated to be 240 ± 40 Tmol si year −1. [36]
Anthony Chabot (/ ʃ ə ˈ b oʊ /; August 13, 1813 – January 6, 1888) was a nineteenth-century businessman and entrepreneur, notable for his contribution to developing hydraulic mining and for building water systems, especially in the Bay Area, so much that he became known as the "Water King".
Berzelius' experiences with glass-blowing had an additional bonus, in 1824 he discovered that one of the constituents of glass was a new element – silicon. Having already discovered three other elements prior to silicon: thorium, cerium and selenium, Berzelius spent the next ten years obsessively measuring more than two thousand chemical ...
In 1909, Albert Samama Chikly took the first underwater shot. [1] In 1910, he filmed Tuna fishing in Tunisia under the patronage of Albert I, Prince of Monaco. [2] In 1940 Hans Hass completed Pirsch unter Wasser (i.e. Stalking under Water) which was published by the Universum Film AG, lasted originally only 16 minutes and was shown in theatres before the main movie, but would eventually be ...
Dr. Halstead (Carl Benton Reid) of the Institute of Oceanography hires Bob Gage (William Lundigan) to supervise the construction of an underwater city.If humans are going to blow themselves sky-high at some point in the future, then it might be a good idea to have an escape hatch down at the bottom of the ocean.
A spacecraft presumed to be of alien origin is discovered on the floor of the Pacific Ocean, estimated to have been there for nearly 300 years.A team of experts, including marine biologist Dr. Beth Halperin, mathematician Dr. Harry Adams, astrophysicist Dr. Ted Fielding, psychologist Dr. Norman Goodman, and U.S. Navy Captain Harold Barnes, is assembled and taken to the Habitat, a state-of-the ...
