[CHN Experiment BATS 2023] - Fecal pellet elemental composition (CHN), production rates, and morphometrics from zooplankton incubation experiments collected during R/V Atlantic Explorer cruise AE2306 at the Bermuda Atlantic Time-series Study (BATS) site in Mar 2023 (Collaborative Research: Zooplankton mediation of particle formation in the Sargasso Sea)

The elemental composition of individual fecal pellets (carbon density and C:N ratios) are reported, along with fecal pellet production rates derived from CHN data and experiment metadata. Supplemental files include zooplankton dry and wet weights for individuals used in elemental analyses, enabling organism-level scaling of elemental fluxes (CHN_Zooplankton.csv), and individual fecal pellet morphometrics and summed volumes for pellets collected for CHN analysis (CHN_Fecal_Pellets.csv).

Together with the related datasets, these data provide integrated measurements linking zooplankton identity, size, fecal-pellet production, pellet elemental composition, and aggregate formation, supporting process-based analyses of zooplankton roles in particle production and vertical carbon transfer at BATS. The data were collected aboard the R/V Atlantic Explorer through the collaborative efforts of the laboratories of Dr.
