14C excess in deep-sea sediments porewater driven by diffusion—Southeast Mediterranean
14C excess deep-sea sediments porewater driven by diffusion— Southeast Mediterranean
font style='font-size:12px;'>
2014/5/26
Core profiles in the deep SE Mediterranean Sea revealed a significant Δ14C excess in the total dissolved inorganic carbon (DIC) of porewater as compared to the Δ14C of the sediments, below the bioturb...
What controls the mixed-layer depth in deep-sea sediments? The importance of POC flux
mixed-layer depth deep-sea sediments The importance of POC flux
