Ever since I read about Deep Sea Hydrothermal Vents in
an issue of Time International magazine, I have become
extremely fascinated with these deep-sea underwater
entities. Some of the literature I have read on the
subject has described one of the properties of
hydrothermal vents to be that of the desalination,
namely, the removal of magnesium salts from the Ocean
Water that is expelled from its channels. The article
states that all of the oceans' water passes through a
hydrothermal vent once every 6 to 8 million years -
thus keeping the salinity of the ocean at a constant
I am doing a project at College and would be extremely
grateful and indebted to you if you could give me
further information about the role of hydrothermal
1. The hypothetical properties of oceans today if
hydrothermal vents were not there to perform the task
of removing Magnesium Salts from them. Would the
oceans be highly viscous and similar to the Dead Sea?
(This is a very important question of which related
answers are not available anywhere in Reference Books
here in INDIA in the city of Rakjot which is a small
town, so this one question I would request you to
please guide me on.)
2. Would such an ocean be able to form the rainwater
clouds that nourish the continents today?
3. What is the size of the apertures in the seabed
through which seawater percolates into a hydrothermal
vent? Are there cracks in the ocean bed or is the
ocean bed porous with microscopic / pin head openings?
