1972年克罗斯海峡浮游植物季节周期的不同寻常特征包括：春季硅藻优势期延长，Pediastrum和Closterium的春季种群发育，Eudorina的6月最大值和Volvox的8月最大值。在水柱的温度、热稳定性和光有效性方面，1972年检测到的特定生长响应与其他年份和其他湖泊的生长响应强烈一致，但保留了种间差异。1972年观测到的浮游生物的非典型季节性是由大气条件的非典型序列引起的，而大气条件的非典型序列又改变了热分层的时间相位和随后的稳定性。这些事件表明浮游植物对环境的物理变化作出反应的重要性。
Unusual features of the seasonal periodicity of phytoplankton in Crose Mere, 1972, included the extended phase of vernal diatom dominance, the development of spring populations of Pediastrum and Closterium, a large June maximum of Eudorina and a large August maximum of Volvox. With respect to temperature, thermal stability and light availability in the water column, the specific growth responses detected in 1972 are shown to be strongly consistent with those in other years and in other lakes, yet the interspecific differences are preserved. The atypical seasonality of plankton observed in 1972 was brought about by the atypical sequence of atmospheric conditions that, in turn, modified the temporal phasing and subsequent stability of thermal stratification. These events demonstrate the importance of phytoplankton responses to physical variability of the environment.
