This volume consists papers dealing with the measurement of photosynthetic pigments in freshwater and standardization of methods, presented at the workshop held in Plön, Germany, in July 1978. The workshop seeks to improve presents technique and stimulate the invention of new methods. These areas include extraction; long term storage of filters; specific absorption coefficients for acetone, methanol, and ethanol in terms of differing percentages of water.
