Dataset: MOCNESS - Zooplankton

Sample Analysis: Samples were split multiple times using a Folsom splitter. Specific taxa were identified and enumerated in one or more splits using a dissecting microscope. Equivalent spherical diameter (ESD) was estimated from length and width and assuming a geometric shape for individual taxa. For discretely sized taxa (Calanus pacificus adult females, adult males, and fifth copepodites: C.pac AF, AM, C5; Metridia pacifica adult females: M.pac AF; Euclanus californicus adult males, adult females, and fourth and fifth copepodites: E.cal AF, AM, C4,C5) mean ESD was calculated from all nets together. For other taxa (other large cops, euphausiids, and small zooplankton), mean ESD was calculated for each net where present and the means were weighted to estimate the mean ESD for all nets. Mean volume was calculated from mean ESD for each taxon using the equation ⅙π (mean ESD)³. Abundance of each taxon was calculated by multiplying counts in each net by their corresponding split factors, summing over all nets and dividing by the sum volume filtered for all nets. Mean volume was multiplied by abundance for each taxon to calculate volume in cm³m^-3 or ppm. Number of individuals measured and counted in each taxonomic group was retained to display where low counts produce uncertainty in calculations.
