The flow cytometer (lower left) counts and measures microbes in the smallest size range (2 - 10 microns). The FlowCAM (below) images, counts and measures cells in the size range from 10 - 200 microns.Water is collected at many depths, filtered at various sizes and run through a fluorometer. The "Pig" (lower right) is where ALL the filtered water drains and needs to be emptied (A LOT) so it won't overflow.

Together these data give us important clues about the base of the marine web: how total photosynthesis is divided amongst various size ranges of cells.
