To investigate temporal (ca 1 mo) and spatial dynamics of bacterioplankton in the Caribbean Sea, time-series measurements of chlorophyll a concentration, bacterial abundance, and thymidine incorporation rate were performed at 6 stations near Barbados, In addition, a series of incubation experiments was carried out with seawater samples collected from various depths and stations to determine bacterial growth rates and removal rates by bacterivory. Vertically integrated phytoplankton and bacterioplankton biomasses averaged 1290 and 1200 mg C m(-2), respectively, and heterotrophic bacterial production was 106 mg C m(-2), with in situ bacterial growth of 0.1 d(-1), Approximately halfway through the sampling period, …
