Abstract |
This project was initiated in 1969 to identify and study processes that were contributing to accelerated eutrophication of Lake Michigan.^Results of several different types of nutrient enrichment experiments showed that inputs of phosphorus to the lake accelerated phytoplankton growth and eutrophication.^It was also shown that there was an imbalance in the inputs of phosphorus and silica to the lake relative to the amounts required by diatoms.^As a result silica concentrations decreased over a 30- to 40-y period to levels that limited diatom production and favored the growth of blue-green and green algae, a generally undesirable environmental change.^These findings indicated that additional research should be conducted on effects of phosphorus and silica on phytoplankton growth and on effects of tributary inputs, which supply large amounts of phosphorus.^In addition research was conducted on the silica cycle to understand processes involved in changing the geochemical environment from silica replete to silica limited for diatom growth. |
