SULFATE PROFILE MAP

METHANE PROFILE MAP

BACK TO BIOGEOCHEMICAL MAPS

Sulfate is the most abundant terminal electron acceptor in sediments deep beneath the seafloor.  Our global SO4-2 map displays the subsurface depths and SO4 -2 concentrations at which downward-diffusing SO 4 -2 stabilizes (circles) or disappears (diamonds) at ODP sites throughout the world ocean (D’Hondt et al., 2002 ). White circles indicate that the SO4-2 stabilizes above five meters below the seafloor. Please check the details of the data and methods that went into making this map.
