Abstract: C technique.Concepts of light interception and conversion ef®ciencies introduced.1980s Eddy covariance technique developed.High precision TCO 2 and O 2 determinations Underestimation of NPP from IBP methods allowed extension of in situ diel techniques to demonstrated.oligotrophic regions.Satellite remote sensing of leaf area and Satellite remote sensing of pigments introduced interception ef®ciency developed (NDVI).and bio-optical algorithms for obtaining Rhizotrons and computerized image analysis for productivity developed.estimating below-ground NPP.Questions about 14 C technique largely resolved.Effective models for scaling from the Emergence of coupled physical-biological modelling.photosynthetic process to canopies developed.Trace element clean techniques allow iron-Mass isotope analysis allows separation of C 4 and C 3 components.limitation to be demonstrated in bottles.HPLC technique for measuring phytoplankton pigments perfected.1990s Long-term eddy ¯ux networks developed.Fast Repetition Rate ¯uorescence technique Links to routine satellite monitoring of regional NDVI.introduced for in situ estimation of Chlorophyll ¯uorescence and absorption photosynthetic ef®ciency.spectroscopic methods for remote sensing of Iron limitation demonstrated unambiguously photosynthetic conversion ef®ciency attempted.during Lagrangian studies involving water mass labelling with SF 6 .Widespread application of analytical ¯ow cytometry to phytoplankton populations.2000+ Major breakthroughs needed:Major breakthroughs needed: Plant respiration models of the detail available for Remote sensing of photosynthetic ef®ciency photosynthesis together with resolution of the to complement remote sensing of pigments direct effects of rising CO 2 .and light attenuation.
