Fig. 3From: Controlling factors of latitudinal distribution of dissolved organic matter in the upper layers of the Indian OceanMeridional distributions of a DOC (μmol kg−1), b a254 (m−1), and c a325 (m−1). Right and left columns represent Leg 2 and 3 transects, respectively. White plus signs represent the mixed layer depths, which we calculated as the depth at which a density increase from the sea surface value was > 0.125 σθBack to article page
