Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon export from the surface ocean. This requires determination of both the Th activity distribution (in order to calculate Th fluxes) and an estimate of the C/ Th ratio on sinking particles, to empirically derive C fluxes. In reviewing C/ Th variability, results obtained using a single sampling method show the most predictable behavior. For example, in most studies that… CONTINUE READING
