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...
In this issue of Oceanography, the majority of the papers presented focus on the harmful health effects of the oceans created by oceanic events, anthropogenic influences, and harmful marine life. Thes...
