Progress Code: completed Statement: Very low chlorophyll and light levels prevented determination of photosynthesis. Data were obtained from vertical profiles of a Fast Repetition Rate Fluorometer (FRRF, Chelsea FASTocean). The full set of parameters available are reported here. FRRF data have been integrated with on board ship data to add location, time. Parameters: Ship parameters Cruise Station Type Date Time Longitude Latitude Bottom depth Depth (of FRRF) FRRF parameters PMTeht (photomultipier) ADC PAR F light F0 Fm light Fm Fv light Fv Fq FvFm Sigma Sigma light NPQ RCII conc Jpsii JVpsii Alhii Chl conc For a table defining these units see Oxborough, K.
