The photosynthetic performance of marinephytoplankton varies in response to a variety of factors, environmental andtaxonomic. One of the aims of the MArine primary Production: model Parametersfrom Space (MAPPS) project of the European Space Agency is to assemble a globaldatabase of photosynthesis? irradiance (P-E) parameters from a range of oceanographic regimes as an aid toexamining the basin-scale variability in the photophysiological response ofmarine phytoplankton and to use this information to improve the assignment of P-E parameters in the estimation of global marine primary production usingsatellite data. The MAPPS P-E database, which consists of over 5000 P-E experiments, provides information on the  patiotemporal variability in the two P-E parameters (the assimilation number, PB m , and the initial slope, _B,where the superscripts B indicate normalisation to concentration of chlorophyll) that arefundamental inputs for models (satellite-based and otherwise) of marine primaryproduction that use chlorophyll as the state variable. Qualitycontrol measuresconsisted of removing samples with abnormally high parameter values and flagswere added to denote whether the spectral quality of the incubator lamp wasused to calculate a broad-band value of _B. The MAPPS database provides a photophysiological data set that isunprecedented in number of observations and in spatial coverage. The databasewill be useful to a variety of research communities, including marineecologists, biogeochemical modellers, remote-sensing scientists and algalphysiologists.
