Description:
During the spring, summer, and fall of 1972 through 1975, the National Eutrophication Survey (NES) sampled 815 lakes throughout the 48 contiguous United States. About 2 1/2-million physical, chemical, and biological measurements were made of the lakes studied. This report, Part I, presents the methodology, rationale, output format, and data limitations of the product. The physical, chemical, and morphometric conditions of the 250 lakes included in the study are described. The mechanics and logic of interfacing physical and chemical data (total phosphorus; orthophosphorus; nitrite-nitrate-, ammonia-, and total Kjeldahl-nitrogen; nitrogen/phosphorus ratio; Secchi disk transparency; chlorophyll a; turbidity; pH; total alkalinity; dissolved oxygen; and temperature) with biological data to establish the environmental requirements and the relative importance of phytoplankton are described.
