Hadal trenches (> 6,000 m water depth) have been revealed as hotspots of organic carbon deposition and mineralization. Here, we present the molecular compositions of porewater dissolved organic matter (DOM) at the “Challenger” Deep (Site MT02; 10

It has been suggested that hadal trenches are depocenters of organic matter and hotspots for microbial activities . Here, we measured the concentrations of pore-water dissolved organic carbon (DOC) in the seven short cores retrieved from three trench
