Planetary Renewal and Life in the Deep Ocean
A large portion of the surface of Earth is continuously rejuvenated over the geological timescale as new ocean floor created at the upwelling zones of mantle convection is subducted at submarine trenches and eventually becomes recycled into the mantle. This dynamic region where new seafloor is created is called mid-ocean ridge, a long chain of volcanoes on the ocean floor whose total length extends more than 70 thousand kilometers. In the past three decades, a great deal of effort has been made by scientists to understand the role of mid-ocean ridge as the source of material and energy from the Earth’s interior within the context of plate tectonics. In more recent years, however, new exciting discoveries of unique organisms at mid-ocean ridges and their extraordinary adaptations to their extreme and ephemeral environment have fascinated both the academic researchers and public. Scientists are now trying to understand the linkage between life and planetary processes at mid-ocean ridge through tightly integrated studies across a broad range of disciplines.
