| Summary: | No abstracts are to be cited without prior reference to the author.Small organisms in the ocean include not only phytoplankton and bacteria, but diverse bacterial grazers and archaea. Local and global climate processes have a direct effect on the vertical stratification and circulation patterns in shelf and off shelf marine waters, which strongly influences the timing and magnitude annual phytoplankton production. Using molecular biology techniques we are now able to identify species and ecotypes of not only phytoplankton but the entire community of microorganisms and it is becoming practical to match community composition with biomass, oceanic processes and biogeochemical pathways.We show from our recent work in Arctic Seas that microbial communities change, not only with depth, but with region and that microbial species mostly track their water mass of origin. For example below the photic zone some watermasses are richer in bacterivores while others are dominated by likely parasites suggesting different ... |
