Data on chlorophyll, primary productivity, and alkaline phosphatase activity for six lakes in Wisconsin, USA, 1984-1995.

Data on chlorophyll, primary productivity, and alkaline phosphatase activity for six lakes in Wisconsin (Peter, Paul, Tuesday, East Long, Central Long, and West Long Lakes), USA, 1984-1995. Samples were collected with a Van Dorn bottle at 6 depths determined from the percent of surface irradiance (100%, 50%, 25%, 10%, 5% and 1%) and in the hypolimnion (12 m in Peter, East Long, West Long, and Tuesday lakes; 9 m in Paul Lake; and 4.5 m in Central Long Lake).
