As soon as possible after collection, the sample is split using a Folsom plankton splitter with subsamples taken for preservation and size-fractionationed biomass.
Bulk plankton from each net and tow were quantitatively split using a Folsom plankton splitter, with additional processing or preservation for several analyses.
The 202 µm samples were size fractioned into two replicate small (202 - 999 µm), one large (1000 - 4999 µm) and one extra large (> 5000 µm) size fractions, split into appropriately sized subsamples using a Folsom splitter, and analyzed by ZooScan
