TLDR
Several lines of evidence indicate that this ice edge bloom was dominated by heterotrophic processes, and rates and ratios of macromolecular synthesis by bacterioplankton were comparable with previous temperature and polar studies.About:

Oceanic Bacterial Production
Hugh W. Ducklow,Craig A. Carlson +1 more
TL;DR: There has been an explosion of research on marine microbial foodweb processes in the past decade as mentioned in this paper, and it is widely accepted that about 50% of the primary production in marine and fresh water is processed by bacteria each day.

Temperature and substrates as interactive limiting factors for marine heterotrophic bacteria
Lawrence R. Pomeroy,W. J. Wiebe +1 more
TL;DR: In temperate ocean surface waters and estuarine waters, growth and respiration may be increased experimentally either by raising the temperature or by increasing organic substrate concentrations, providing indirect evidence that the lim- itation is an effect of temperature on substrate uptake or assimilation.

TL;DR: In this paper, new estimates of Arctic and Antarctic production of biogenic carbon are derived, and differences as well as similarities between the two oceans are examined.
Journal ArticleDOI
Coastal zone color scanner pigment concentrations in the Southern Ocean and relationships to geophysical surface features
TL;DR: In this article, the authors examined the distribution of surface pigment fields in the entire southern ocean over a seasonal cycle and identified the occurrence of intense phytoplankton blooms during austral summer months and during other seasons in different regions.

The influence of oceanographic processes on pelagic-benthic coupling in polar regions: A benthic perspective
TL;DR: In this article, the influence of oceanographic processes on benthic community abundance and biomass in polar marine systems is directly influenced by food supply from the overlying water column, which results in food-limited regimes for the underlying benthos.

Bacterial production in fresh and saltwater ecosystems: a cross-system overview
TL;DR: Heterotrophic bacterial production is a large component of total secondary production and is roughly twice as large as the production of macrozooplankton for a given level of primary production.
Journal ArticleDOI
The supply and accumulation of silica in the marine environment
TL;DR: For example, the accumulation of biogenic silica in estuarine deposits removes a maximum of 8 × 1014g SiO2/yr or 10% of the dissolved silica input to the oceans as mentioned in this paper.
Journal ArticleDOI
Leucine incorporation and its potential as a measure of protein synthesis by bacteria in natural aquatic systems.
TL;DR: The results demonstrate that the incorporation rate of [3H]leucine into a hot trichloroacetic acid-insoluble cell fraction can serve as an index of protein synthesis by bacterial assemblages in aquatic systems.

Bacterioplankton secondary production estimates for coastal waters of british columbia, antarctica, and california.
Jed A. Fuhrman,Farooq Azam +1 more
TL;DR: 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.
Journal ArticleDOI
Bacterial dry matter content and biomass estimations.
Gunnar Bratbak,I. Dundas +1 more
TL;DR: It is found that the dry-matter content of bacteria may be more than twice as high as generally assumed and to convert bacterial biovolume into biomass (carbon content), it is suggested that 0.22 g of C cm-3 should be used as a conversion factor.
