Primary productivity, carbon 14, scintillation counting, winter, Red Haw
Primary production studies were conducted on an 83-acre lake in south central Iowa during the summer of 1970 and winter of 1971. Primary productivity was measured using the light dark bottle method. Summer values ranged from 2.74 to 6.25 grams of carbon assimilated/m2/day. This was correlated with water temperature, nitrate nitrogen, ortho phosphates, carbon dioxide, light penetration and plankton populations. Studies were continued during the winter using C14 and scintillation counting methods.
