Gelatinous zooplankton were collected on four research cruises on the R/V Sally Ride and R/V Roger Revelle between 2020 and 2023 and from 0 to 3,000 m depth using a 10 m2 Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS). 561 samples of gelatinous zooplankton from 13 taxonomic groups were chosen for bulk tissue stable isotope analysis. An additional twenty samples from seven gelatinous genera were chosen for nitrogen compound-specific isotope analysis of amino acids because they were abundant across our region and represented a range of hypothesized feeding guilds and depth habitats (0 – 1,025 m). Gelatinous zooplankton were briefly thawed to remove visible gut contents using forceps and a scalpel. Samples were then lyophilized and homogenized. To ensure sufficient sample mass for stable isotope analysis, samples often contained multiple individuals from the same net, taxonomic group, and size class. The number of individuals per sample was typically fewer than 100, with a larger number of individuals pooled for some samples of Pantachogon spp. and Hormiphora spp. Samples were processed for nitrogen compound-specific isotope analysis at the Laboratory for Marine Organic Isotope Geochemistry at the University of Miami. This dataset includes the nitrogen compound-specific isotope values of amino acids for each gelatinous zooplankton sample and the sample's estimated trophic position.\n\ncdm_data_type = Other\nVARIABLES:\nspecimen_number (unitless)\nbest_taxonomic_ID (unitless)\ntow (unitless)\nnet (unitless)\nDate_UTC (unitless)\nyear (unitless)\nmonth (unitless)\nday (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\n...

Siphonophore samples were collected on four research cruises on the R/V Wester Flyer between 2019-2021. To remove potential biases associated with tissue‑specific variability in stable isotope values, the gelatinous swimming bells (nectophores) of siphonophores were sampled. This approach was possible for most specimens, except for physonect species that are extremely fragile or have nectosomes that are a small fraction of the colony length and are often not collected. For these species (e.g., Apolemia spp.), the gelatinous bracts and pieces of the siphosome, excluding gastrozooids, were used. For small individuals (Diphyes dispar, Nanomia bijuga, and Sphaeronectes koellikeri), nectophores from several colonies that were captured at the same time and sampling location were pooled to obtain an adequate mass for isotope analyses. A subset of samples was selected for compound-specific isotope analysis of amino acids. These specific taxa were selected as representatives of different depth habitats, suborders, and hypothesized diets. Bulk and compound-specific isotope analyses were performed at the University of Hawaii's Biogeochemistry Stable Isotope Facility. This dataset includes the compound-specific isotope analysis data.\n\ncdm_data_type = Other\nVARIABLES:\nCollection_Date (unitless)\nYear (unitless)\nMonth (unitless)\nGenus (unitless)\nBest_Taxonomic_ID (unitless)\nAlanine (parts per thousand)\nGlycine (parts per thousand)\nThreonine (parts per thousand)\nSerine (parts per thousand)\nValine (parts per thousand)\nLeucine (parts per thousand)\nIsoleucine (parts per thousand)\nProline (parts per thousand)\n...
