Annual dynamics of bacterial biomass and production in Franklin Bay, western Canadian Arctic

Microbial and environmental variables were collected from 8 depths at a 200-m deep site in Franklin Bay on 33 occasions, from 4 November 2003 to 6 August 2004, aboard the CCGS Amundsen. The following variables were measured: depth, temperature and salinity (Seabird 911+ CTD); CDOM (coloured dissolved organic matter) absorption coefficient at 320 nm (Varian Cary Bio 300 scanning spectrophotometer); chlorophyll a (ethanol pigment extraction); bacteria abundance (epifluorescence microscopy); tritiated leucine and thymidine incorporation rates (centrifugation method). Bacterial carbon production (BP) was estimated from leucine incorporation using the carbon conversion factor of 1.5 kgC/mol of leucine incorporation. BP was also estimated from thymidine incorporation using (1) the empirical carbon conversion factor of 2.0 x10^18 cells/mol of thymidine incorporated and (2) the bacterial cellular biomass of 10 fgC/cell.
