Life And Energy In Deep And Shallow Hydrothermal Systems Near The Mexican Coast Of The Pacific Ocean
Conference Paper: Life And Energy In Deep And Shallow Hydrothermal Systems Near The Mexican Coast Of The Pacific Ocean
AbstractDeep submarine energy is related to the existence of hydrothermal vents emerging in many places along the oceanic spreading centers between tectonic plates. These systems have a total length of about 65,OOOkm in the Earth's oceanic crust. Shallow submarine heat is related to faults and fractures in the sea bottom close to some coasts. Hydrothermal submarine reservoirs contain an essentially infinite energy potential. Geothermal energy in Mexico embraces both near-suface ~ d i t i o rnes~er voirs located between 500 to 3000 meters depth, and deep geothermal resources at more than 3000 meters depth. Non-traditional geothermal energy sources in Mexico include the deep portions and ~ ~of ~diti~onahl ydreothe~arles servoirs, systems in hot dry or wet rock, geopressured reservoirs in the Gulf of Mexico and hydrothermal submarine systems located mainly close to the Mexican coast of the Pacific Ocean. There are two kinds of such systems: deep resources, located at certain places along the rifts between tectonic plates of the oceanic crust at more than 2000m below sea level, and shallow resources near to continental platforms at 20-50m depth. This type of shallow subsea system was found offshore at Punta Banda in Ensenada, Baja Califomia. Both types of resources exist in the Gulf of Calfornia. The specific chemical characteristics of the submarine hydrothermal waters found in those systems, indicate that water-oceanic rock interactions occur at high temperature and high pressure conditions. At the same time, s u bm~ ngee othermal energy supports rich biological communities at depths where living organisms cannot use sunlight for photosynthesis. Recent research suggests that possible locations for the synthesis of chemicals needed for the origin of life could be s u bm~ nhey drothermal systems.
