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.
