Authigenic rhenium, manganese and opal concentrations in the Deep South Atlantic from 370 to 450 ka

This data reports measured concentrations of the trace elements rhenium and manganese, the major component biogenic opal and the estimated fraction of rhenium and manganese that are authigenic in nature (aRe and aMn) from the sediment record of Ocean Drilling Program Site 1094 in Atlantic sector of the Southern Ocean for the time period spanning 370 and 450 thousands years.
