Seasonal changes of dissolved organic carbon (DOC), nitrogen (DON), phosphorus (DOP), chlorophyll a, and primary production were followed for 17 months in the permanently well mixed waters of the English Channel. There was a proportionality between the intensities of Chl a and the subsequent DOC peaks and the increase in DOC from a previous low value, showing that a major part of the DOC is produced through degradation of particulate organic matter. This DOC production was equivalent to 66 g C · m −2 · yr −1 . Phytoplankton excretion may add about 16 g C · m −2 · yr −1 to the DOC pool. The DOM production following a phytoplankton bloom was characterized by a sequential appearance of DON, DOC, and DOP.
