Virio- and bacterioplankton microscale distributions at the sediment-water interface.

ABSTRACT: The marine sediment-water interface is an important location for microbially controlled nutrient and gas exchange processes. While microbial distributions on the sediment side of the interface are well established in many locations, the distributions of microbes on the water side of the interface are less well known. Here, we measured that distribution for marine virio- and bacterioplankton with a new two-dimensional technique. Our results revealed higher heterogeneity in sediment-water interface biomass distributions than previously reported with a greater than 45- and 2500-fold change cm(-1) found within bacterial and viral subpopulations compared to previous maxima of 1.5- and 1.4-fold cm(-1) in bacteria and viruses in the same environments. The 45-fold and 2500-fold changes were due to
