Dissolved nutrients, cell counts, and nitrogen isotope measurements from Chaetoceros culture experiments Data DOI: https://doi.org/10.15784/601724 Cite as Dove, I. (2023) "Dissolved nutrients, cell counts, and nitrogen isotope measurements from Chaetoceros culture experiments" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/601724. AMD - DIF Record(s) USAP-1744871_1 Abstract This dataset is the results of 3 experiments in which the spore-forming diatom Chaetoceros socialis was grown in culture and induced into resting spores by nitrate limitation. The nitrogen isotopic composition of accumulated biomass (δ15Nbiomass; ‰ vs air) and of diatom-bound organic N (δ15Ndb; ‰ vs air) are reported at two timepoints from each experiment: prior to and after resting spore formation. Experiments 1 and 2 provide measurements for CRS mixed with vegetative Chaetoceros cells, while Experiment 3 provides measurements for isolated CRS. Fluorescence and nitrate concentration was tracked throughout each experiment, with dissolved silica, ammonium, and total reduced nitrogen also measured in Experiment 3.
