Protein content and protein synthesis rates of planktonic marine bacteria
Bacterial protein production method was an order of magnitude more sensitive and yielded bacterial carbon production directly without the need to know the cell size of the part of the assemblage in growth state.
The Ecological Role of Water-Column Microbes in the Sea*
Evidence is presented to suggest that numbers of free bacteria are controlled by nanoplankton~c heterotrophic flagellates which are ubiquitous in the marine water column, thus providing the means for returning some energy from the 'microbial loop' to the conventional planktonic food chain.
Thymidine incorporation as a measure of heterotrophic bacterioplankton production in marine surface waters: Evaluation and field results
To assess bacterioplankton production in the sea, we have developed a procedure for measuring growth based on incorporation of tritiated thymidine into DNA; the accuracy of this procedure was tested…
A simple, economical method for measuring bacterial protein synthesis rates in seawater using 3H-leucine
A simplified method is presented for using 3H-leucine (3H-leu) incorporation to measure bacterial protein synthesis rates in seawater. This method uses small volumes (< 2.0 ml) of seawater and…
Bacterioplankton Secondary Production Estimates for Coastal Waters of British Columbia, Antarctica, and California
In all three regions studied, it appeared that a significant fraction of the total primary production was utilized by the bacterioplankton and that substantial growth could occur in the absence of large particles.
Intense hydrolytic enzyme activity on marine aggregates and implications for rapid particle dissolution
LARGE, rapidly sinking organic aggregates are an important component of the carbon flux from the ocean's surface to its depths. Marine snow, the main type of large (<0.5 mm) aggregate, is heavily…
Microbial production of recalcitrant dissolved organic matter: long-term carbon storage in the global ocean
The microbial carbon pump is proposed as a conceptual framework to address the important, multifaceted biogeochemical problem of fixed carbon in the upper ocean.
Microbial Control of Oceanic Carbon Flux: The Plot Thickens

In his commentary Azam summarizes new work indicating that microbes in the ocean lead much different lives than the authors had supposed, and can have enormous influence on the overall carbon flux in the environment.
The oceanic gel phase: a bridge in the DOM-POM continuum
Abundance and production of bacteria and viruses in the Bering and Chukchi Seas
The distribution, abundance, and production of viruses and bactena were investigated during an August to September 1992 cruise aboard the RV 'Alpha Helix' in the Bering and Chukchi Seas and suggest viruses to be a ubiquitous and dynamic feature and a significant source of bacterial mortality in Arct~c marine microbial communities.
