title: A simplified method of recovering CO2 from bacterioplankton respiration for isotopic analysis.
abstract: A method for recovering CO2 respired by bacterioplankton for analysis of carbon isotopes was adapted for use with standard laboratory equipment without a technically demanding harvest line. The recovered CO2 was more depleted in (14)C than the dissolved organic carbon (DOC) source, which suggests a selective respiration of older carbon.
