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 meters depth using a 10-square-meter Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS). 561 samples of gelatinous zooplankton from thirteen 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 meters). 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 bulk tissue stable isotope analysis at the University of Hawaii at Manoa and the University of California Merced. This dataset includes the bulk tissue stable isotope measurements of carbon and nitrogen as well as specimen metadata (e.g., animal body size, collection location/time).\n\ncdm_data_type = Other\nVARIABLES:\nspecimen_number (unitless)\nphylum (unitless)\ngenus (unitless)\nbest_taxonomic_ID (unitless)\ntow (unitless)\nnet (unitless)\nDate_UTC (unitless)\nyear (unitless)\nmonth (unitless)\nday (unitless)\n...

Particle samples were collected via sequential size fractionation using McLane in-situ pumps on two cruises conducted aboard the R/V Kilo Moana in February (KM1407) and September (KM1418) 2014. Data were collected as part of a project focused on characterizing sources of nutrition for the mesopelagic animal food web, for which particulate organic matter was a crucial baseline resource. In addition, differences in the nitrogen isotopic ratios of individual amino acids from particle size fractions and over depth provide insight into phytoplankton origins and microbial or zooplankton alteration of particulate matter involved in carbon export. Compound-specific isotopic data and amino acid quantities were collected using gas chromatography-isotope ratio mass spectrometry, and bulk isotopic data and quantities were collected using elemental analysis-isotope ratio mass spectrometry, both at University of Hawaii. Dr. Hilary Close (former affiliation: University of Hawaii, current affiliation: University of Miami) was the primary investigator involved in sampling and analysis of data presented here.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nISO_DateTime_UTC_rep (seconds since 1970-01-01T00:00:00Z)\nDate_local (unitless)\nTime_local (unitless)\ndepth (m)\nSize_Fraction_Min (micrometers (um))\nSize_Fraction_Max (micrometers (um))\nVolume_Filtered_AAd15N (liters (L))\nd15N_Bulk (permil relative to AIR (‰))\nd15N_Ala (permil relative to AIR (‰))\nd15N_Gly (permil relative to AIR (‰))\n...

Size-fractionated particles were collected via in situ filtration and sinking particles were collected via sediment traps in May 2021. Size-fractionated particles were collected from 20 meters (m) to 500 m at various depths, depending on particle type. At 30 and 340 m, five size fractions were collected for both bulk and amino acids isotopic analysis: 0.3-1 micrometers (μm), 1-6 μm, 6-51 μm, 51-335 μm, and >335 μm. At 20, 50, 75 or 95, 125 or 145, 175 or 195, 330, and 500 m, two size fractions were collected for amino acid isotopic analysis: 0.8-51 μm particles and >51 μm particles. Particle data were used to determine major processes altering particulate organic matter. The collection of these data was supported by NSF.\n\ncdm_data_type = Other\nVARIABLES:\nCruise_sample_number (unitless)\nTrap_ID (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nStart_latitude (decimal degrees)\nEnd_latitude (decimal degrees)\nStart_longitude (decimal degrees)\nEnd_longitude (decimal degrees)\ntime (Midpumping_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nStart_time_UTC (unitless)\nEnd_time_UTC (unitless)\nDate_local (unitless)\nTime_local (unitless)\nStart_date_local (unitless)\nEnd_date_local (unitless)\nStart_time_local (unitless)\nEnd_time_local (unitless)\ndepth (m)\n...
