摘要：Obrvations were made on the vertical distribution of colonies of Aphanizomenon flos-aquae for 9 d at a drift-station east of Bornholm Island in the Baltic Sea. The buoyant colonies were disperd in the upper layers of the water column during periods of wind-induced mixing but floated up during calm periods. From measurements of the vertical light extinction, surface irradiance and the photosynth倍数表达法英语

esis versus irradiance curve, calculations were made of the changes in the daily integral of photosynthesis with respect to time and depth throughout the water column. From the calculations it is demonstrated that net photosynthesis by the population of Aphanizomenon flos-aquae incread nearly threefold by floating up after a deep mixing event. It is estimated that, averaged over alternating periods of calm and mixing, the
