Fig. 3: The distribution of the degradation rates of dissolved organic carbon (DOC) and spectral parameters with depth across three oceans.

a–c The Pacific Ocean. d–f The Indian Ocean. g–i The Atlantic Ocean. a, d, g d(DOC)/d(depth) (L μmol L−1 km−1). b, e, h d(ag(275)/DOC)/d(depth) (L μmol−1 km−1 m−1). c, f, i d(ag(380)/DOC)/d(depth) (L μmol−1 km−1 m−1). The left graph in each panel depicts the average ratio of gradient (RG), which quantifies the percentage of degradation in DOC or spectral parameters that would occur with a decrease in depth with unit 1 km.
