Note: Total and solar energy-dependent entropy productions (per year per MJ of absorbed solar radiation energy per m3 of the lake water) are shown, respectively, in the first and in the second column, and entropy productions independent of solar radiation energy (per year m3 of the lake water) are in the third column. Units are (kJK-1 m-3 year-1). Ratios of the values for the two lakes are shown in the last row.

amount of dissolved organic matter and SS in the lake water by means of reactions to incident solar radiation.

The entropy production independent of solar radiation energy (Table 9.3) is the measure of activity of respiration of organisms distributed over the whole water column. The ratio of the amount of plankton plus zoobenthos in Lake Mendota with respect to Lake

Biwa is 3:9 and is consistent with the ratio of entropy production independent of solar radiation (3:6). The larger the amount of organisms, the more the entropy production is independent of solar radiation. The entropy productions in eutrophic Lake Mendota are larger than those in oligotrophic Lake Biwa in any of the categories considered (i.e., due to light absorption, respiration, and total).

Figure 9.4 reports the linear regression curves between d and TSI, TSI (SD) (Carlson, 1977) and the mean depth (because of the little data available, the regression curves cannot

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
