Dataset: Carbon, nitrogen, d13C, and d15N water column data from the "SalpPOOP" cruise on R/V Tangaroa during October and November 2018

Samples were collected by Niskin bottle and transferred into 2.2-L amber polyethylene bottles. They were then immediately vacuum filtered through pre-combusted GF/F filters. Filters were covered in pre-combusted aluminum foil and placed in cryovials. They were then placed in a -80C filter until they could be dried in a drying oven for shipping. Post-cruise, samples were acidified with fuming HCl, then thoroughly dried again and put into tin capsules. Samples were analyzed by isotope ratio mass spectrometer at the U.C. Davis Stable Isotope Facility.
