Plankton size spectra compiled from projects CCE LTER, HOT, CRD FluZIE, BLOOFINZ-GoM, and SalpPOOP in the California Current Ecosystem, North Pacific subtropical gyre, Costa Rica Dome, Gulf of Mexico, and Southern Ocean subtropical front from 2004-2018

This dataset includes compiled plankton size spectra from 5 different projects: California Current Ecosystem Long-Term Ecological Research (CCE LTER) process cruises, Hawaii Ocean Time-series (HOT) cruises, Costa Rica Dome Fluxes Zinc and Iron Experiments (CRD FluZIE), Gulf of Mexico Bluefin Larvae in Oligotrophic Ocean Foodwebs, Investigations of Nutrients to Zooplankton (BLOOFINZ-GoM), and Salp Particle expOrt and Ocean Production (SalpPOOP) spanning 2004 to 2018. Biomass was determined using three different methods: flow cytometry for less than 2-micron cells, epifluorescence microscopy for 2 - 200 um cells, and size-fractionated zooplankton net tows for >200-um organisms.
