This is the second version (ver. 2) of Marine Zooplankton Metabolic Data, first published in 2008. Metabolic rate data, in terms of oxygen consumption, ammonia-N excretion or phosphate-P excretion, represent those determined on fresh wild zooplankton collected from various locations of the world’s oceans with a sealed-chamber method (Omori and Ikeda 1984, Ikeda et al. 2000) at near in situ temperatures. All rate values listed are raw data, not a mean of each species being used for various statistical analyses in the papers in Reference. Tables in the ver. 2 are more extensive than in the first version; they present more detailed entries of data collected since 2008. New entries of the data and corrections of minor typographical errors found in the first version are shown in red. Notes for Table 1: ”Subcode” is to separate the data of the same species into sex (F: female. M: male), developmental stage (juv: juvenile, C: copepodid stage for Copepoda), maturity condition, or collections of different dates and/or locations. “Taxon” was added for each “Species”. Notes for Table 2; “Depth” where zooplankton collected was represented by the midpoint of vertical ranges of the nets towed. For mesopelagic and bathypelagic zooplankton collected by using nets without closing mechanism, the depth of the epipelagic zone (200m) took into account in this calculation. In addition to “Dry mass”, “carbon (C)”, nitrogen (N)” and phosphorus (P)” being used as a measure of body mass in the first version, “Wet mass” and “Ash content” were given as “Supplemental data” for some species. For readers who wish to know more details about the data of interest, please refer original papers in Reference in Table 1. I hope that the data are useful to advance our knowledge about zooplankton physiology and energetics toward better understanding of their dynamic roles in matter cycling and energy flow in marine pelagic ecosystems.
