Abstract
Carbon-14 production measurements and chlorophyll profiles are presented for a lake with a metalimnetic production maximum. Annual phytoplankton production is estimated as 50 g Cim year. Lakes of this type are quite common yet present difficulties in classifying lakes by production measurements and in using infrequent measurements to infer temporal trends in productivity. The results of two different liquid scintillation methods are compared, and data are presented which suggest that counting efficiencies may be reliably determined in Aquasol, a xylene based fluor, by either the internal standard or channels ratio techniques.
