| Method |
Primary source Bjørnsen abstract: "Image analysis was applied to epifluorescense microscopy of acridine orange-stained plankton samples. A program was developed for discrimination and binary segmentation of digitized video images, taken by an ultrasensitive video camera mounted on the microscope." Primary source Lee and Fuhrman abstract: "In the present study, natural bacterioplankton assemblages were freshly collected, passed through 0.6-mum-pore-size Nuclepore filters to remove larger particulate materials, and diluted for growth in 0.22-mum-pore-size Millipore filter-sterilized unenriched seawater." |

P.210 left column 4th paragraph: "[Investigators’] results are consistent with, and explain, recent findings of very high C:cell volume ratios determined from carbon measurements in bacterial cultures or in size-fractionated natural bacterial assemblages: 354 mg C/ml (primary source Bjørnsen 1986), 380 mg C/ml (primary source Lee and Fuhrman, 1987) and 560 mg C/ml (primary source Bratbak 1985)." |
