Title: Carbon-13 depletion in a subalpine lake: carbon flow implications

Journal Article · · Science; (United States)

Plankton (larger than 76 micrometers) taken from an undisturbed oligotrophic lake was found to have delta /sup 13/C values (=/sup 13/C//sup 12/C relative to the Pee Dee belemnite standard) ranging from -44 to -47 per mil. This extraordinary /sup 13/C depletion, together with characteristics of the inorganic carbon pool, indicates that lake respiration as well as surrounding soil respiration provide important carbon sources for plankton production in this lake.
