Anotace	In the northern Gulf of Eilat (Aqaba), sharp increases (within 24 hours) in the biomass of diatoms and rates of primary production occurred in April 2008. Euphotic depth decreased from 60 to 45 m. During this time, a significant increase in silica deposition by the diatoms was also detected. We attribute the mentioned changes in environmental characteristics to wind-generated surface currents. Strong winds enriched the surface layers with unusually high nutrient concentrations within <1 d. Hence, primary production rates were observed at a relatively eutrophic nearshore station and pelagic station. They were compared with rates measured on the subsequent day. Values measured were twice as high as those at the pelagic station during the previous calm day. Routine monitoring programs with monthly or semi-weekly sampling are thus likely to miss brief but significant injections of nutrients, leading to the underestimation of seasonal and annual primary production.
