From the Mantle to Microbes: The Lost City Hydrothermal Field
Lost City Hydrothermal Field Microbes
2015/7/28
For over two decades, explorers of the deep ocean have been enthralled by volcanically driven black smoker hydrothermal systems hosting organisms that live under some of the most extreme conditions on...
Past and Future Impact of Deep Drilling in the Oceanic Crust and Mantle
Past and Future Deep Drilling Oceanic Crust and Mantle
2015/7/24
Knowledge of the composition of oceanic crust is critical for calculating the fluxes of mass, heat, and volatiles from Earth's interior to its crust, oceans, and atmosphere. In the great debate over c...

Links from Mantle Microbe Lau Integrated Study Site Back-Arc Spreading Center
2015/7/14
The Lau Integrated Study Site (ISS) has provided unique opportunities for study of ridge processes because of its back-arc setting in the southwestern Pacific. Its location allows study of a biogeogra...

Hot mantle drives elevation volcanism along mid-ocean ridges
2014/4/16
By analyzing the speed of seismic waves generated by earthquakes, scientists have shown that temperature differences deep within Earth’s mantle control the elevation and volcanic activity along mid-o...
