Horizontal Spatial Variation in the Lake
Up to this point most of the analysis has dealt with samples taken from the index station in the middle of the lake. The question arises how typical the index station is of the lake as a whole. This question is answered here in two stages. First, an analysis is made of the five-station heterogeneity series. As described in Chapters 2 and 3, this series consisted of analyses made on a set of samples taken on 32 different dates at the four main stations and the index station. The top (0–5 m) and bottom of the water column were sampled at each station. Since each one of the four main stations was located at the mouth of one of the four main arms of the lake, this sample series gives information about the degree of variation to be expected over the deep-water section of the lake.
