1961-63 年期间，在三十个月的时间内，每周两次对梅奈海峡的浮游植物进行了定量采样。还进行了天气物理测量（盐度、温度和 secchi 圆盘读数）和叶绿素测定。分析了整个时期这些水域中浮游植物的物种组成变化以及硅藻主要水华的动态。这些水域中的浮游植物通常在四月或五月只出现一次主要的多物种水华，但个别物种有时会在当年晚些时候产生二次水华。定量记录和叶绿素结果表明，这些水域中通常不会出现大量浮游植物，尽管如此，这些水域的养分却因陆地排水而显着富集。在主要的春季花期期间，各种根管藻通常占主导地位，但通常在春季硅藻花期之后生长的褐囊藻在初夏的较长时间内主导浮游植物。此时，水中几乎所有浮游植物都是小鞭毛虫。即使在较大的中心硅藻大量繁殖期间，纳米浮游生物物种在这些水域中的浮游植物中也占较大比例（按体积计）
The phytoplankton of the Menai Straits has been sampled quantitatively at twice weekly intervals over a period of thirty months in the years 1961–63.Synoptic physical measurements (salinity, temperature and secchi disc readings) and chlorophyll determinations were also made. The variation in species composition of the standing crop of phytoplankton in these waters throughout the period and the dynamics of the main bloom of diatoms are analysed. The phytoplankton in these waters usually exhibit only one major multi-species bloom in April or May but individual species sometimes produce secondary blooms later in the year. The quantitative records and the chlorophyll results show that large standing crops of phytoplankton do not usually occur in these waters which are, none the less, markedly enriched in nutrients by land drainage. During the main spring bloom, various species ofRhizosoleniaare usually dominant but the growth ofPhaeocystiswhich usually succeeds the spring diatom bloom dominates the phytoplankton for extended periods in the early summer. At these times virtually all the phytoplankton in the water are small flagellates. Even during the bloom of the larger centric diatoms, the nanoplankton species form the greater proportion (by volume) of the phytoplankton standing crop in these waters
