Abstract
In situ beam transmissometer and dissolved oxygen data from the Sargasso Sea (20 m) were plotted as a function of PAR (photosynthetically available radiation), for a 14-day period in spring during the BIOWATT Experiment (1987). These pseudo P versus I curves reflect complicated diurnal trends in in situ beam attenuation and in dissolved oxygen which are produced by either advection, cloud cover, or both. Generally, particle concentrations are coherent with dissolved oxygen concentrations, except at the onset of advective periods. Peaks in particle concentration and dissolved oxygen lagged peaks in PAR by 4–6 h for all 14 days.
