在缅因州海湾的浮游植物的生活条件被发现与那些从北方沿海沃茨描述的一致。在夏季，表层或多或少是分层的，表明湍流程度相当低。在分层被垂直混合打破的地方，沃茨是如此透明，以致湍流对生产力的总影响是有利的，营养盐的供应导致种群的增加，超过了垂直迁移造成的损失。在芬迪湾，由于潮差异常高，沃茨的湍流全年都很强烈，以致其硝酸盐和磷酸盐含量几乎总是很高，即使在水面上也是如此。因此，浮游植物的生产几乎不会受到营养盐缺乏的限制。沃茨相对较高的浊度和多云天气使产油区变浅。因此，高度的湍流甚至可能…
In the gulf of Maine life conditions of the phytoplankton were found to be in agreement with those described from the coastal waters of Northern Europe. The surface layers are during summer more or less stratified, indicating a fairly low degree of turbulence. Where the stratification is broken up, by vertical mixing, the waters are so transparent that the total effect of the turbulence on the productivity is favourable, the supply of nutrient salts resulting in an increase of the population, exceeding the loss by vertical transport. In the bay of Fundy, on account of the exceptionally high tidal range, the turbulence of the waters is so strong throughout the year that their nitrate and phosphate content nearly always was found to be high, even at the surface. The production of phytoplankton, therefore, can hardly be limited by the lack of nutrient salts. A relatively high turbidity of the waters and much cloudy weather make the productive zone shallow. Consequently the high degree of turbulence may even ...
