As oceanic crust is formed, saline ocean water circulates deeply through the basalt and gabbro forming in the hot environment of the mid-ocean ridges
The upper temperature limit of the model corresponds to the highest vent temperature observed in mid-ocean ridge
hydrothermal systems (405-407[degrees]C) [19, 57].
Large amounts of seawater permeate deeply into the oceanic crust through fracture zones at mid-ocean ridge
, where the seawater is warmed by heat sources.
This fracture zone represents the trace of a transform fault of the mid-ocean ridge
before the formation of the Easter Microplate more than 2 Myr ago (Hey et al, 1995; Martinez et al, 1997).
Second, when non-transform offsets of mid-ocean ridge
segments were first recognized along the Galapagos Spreading Centre and East Pacific Rise, application of the concepts learned there were key to reconstructing the history of the Juan de Fuca Plate (Riddihough 1977, 1984; Riddihough et al.
As it pumps lava up, it forces each wall of the mid-ocean ridge
to move aside," explains Lutz.
Meanwhile, environmentalists raise concerns about the long-term effects of siphoning off energy from the mid-ocean ridge
All the ocean floors are created at the mid-ocean ridge
, a 60,000 km long volcanic mountain range winding round the globe from Iceland to the Pacific.
"We know less about deep oceans than about the dark side of the moon," says Joe Cann, a professor at Leeds Univ., England, and head of the steering committee for the British Mid-Ocean Ridge
The Mid-Atlantic Ridge is a mid-ocean ridge
located along the floor of the Atlantic Ocean.
The findings show the East Pacific Rise, the Earth's dominant mid-ocean ridge
, is dynamic as heat is transferred.
