    Abstract
    In the context of remote sensing of the ocean, the general problem of estimating water column production from surface irradiance and column chlorophyll concentration is examined, and some refinements are made to the linear theory presented by PLATr (1986, Deep-Sea Research, 33, 149-163) Further empirical evidence is presented to show the stability of the relationship between surface light and biomass-normalized primary production of the ocean water column A theoretical explanation is given for the non-zero intercept often obtained when these two variables are regressed The systematic errors in the estimation of primary production by remote sensing, due to non-uniformity in the biomass profile, are examined through sensitivity analyses on a generalized biomass profile The errors are shown to be functions of the parameters of the biomass profile, of the photosynthetic parameters and of the optical properties of the water The probable random errors in the estimation of water column primary production using remotely sensed data are evaluated Some general issues related to the collection and assimilation of data on ocean primary production are addressed.
