一个基于计算机的模式，确定生产的浮游植物，集成在深度和任意时间间隔，描述。该解决方案结合了光抑制，并使用感兴趣的时间间隔的表面辐照度的实际分布，因为它是不可能预测的详细性质的云量。从实验数据有关的碳吸收率的辐照度的模型参数估计的统计程序进行说明。该模型适用于从1970年5月27日至1971年2月3日从密歇根湖收集的数据。整体初级生产力是双峰在近海和近海站的最低生产在仲夏和冬季。有很大的每日变化的整体生产，由于光的变化。由此可以推断，偶尔在现场测量会给一个真正的季节性trends.The模式输出的知识非常贫穷进行了验证，通过两个现场实验。协议是更好的T…
A computer-based model for determining production by phytoplankton, integrated over depth and over an arbitrary time interval, is described. The solution incorporates light inhibition and uses the actual distribution of surface irradiance for the time interval of interest, since it is not possible to predict the detailed nature of cloudiness. Statistical procedures for estimating the model parameters from experimental data relating the rate of carbon uptake to irradiance are described. The model is applied to data collected from May 27, 1970 through February 3, 1971 from Lake Michigan.Integral primary production was bimodal at inshore and offshore stations with minimum production in midsummer and winter. There was great daily variability of integral production, due solely to variation of light. From this it is inferred that occasional in situ measurements would give a very poor knowledge of true seasonal trends.The model output was verified by performing two in situ experiments. The agreement was better t...
