Spatiotemporal variation in the dissolved black carbon in three estuaries

This dataset contains the following data: sampling date, sampling locations, sample depths, salinity, total suspended matter (TSM) concentration; dissolved black carbon; and the deviation of dissolved black carbon to the conservative mixing between fresh and saline end-members. The dataset is the supplementary material for the manuscript entitled "<b>The flood-ebb-tide regulated seaward export of dissolved black carbon across estuaries</b>".
