Heterotrophic bacterial production using 3H-Leucine incorporation from discrete bottle samples from CCE process cruises in the California Current System, 2007 - 2017 (ongoing).

Seawater samples were taken from 6 depths from each mid-day CTD cast to estimate rates of bacterial protein synthesis using the 3H-Leucine incorporation method. Bacterial protein synthesis was converted to bacterial production estimates. These samples are used to further understanding of secondary production and sinks for primary production that can be used to monitor chages at the base of the food web over time.
