For the purposes of this calculation transparent particles e.g., diatom frustules, are not particles. CDG and CDD: Numbers of cells observed DIVIDING (a cell with an invagination) and DIVIDED (two adjacent cells of identical morphology with a distinct space between them). Cells counted in these two categories are not also tallied under ON and OFF particle categories. VIEW: The total number of fields of view observed during a cell count on a filter. A: Filter area ratio. Total countable area of the filter divided by the area of filter observed for one field of view. BT and BD: VCT: D: Dilution factor of original sample expressed as a proportion, e.g., 1 cm3 of sediment in 9 ml of formaldehyde will give D = 0.1 back to top
