©2020 Biological and Chemical Oceanography Data Management Office.This dataset presents bulk stable isotopes (13-carbon and 15-nitrogen) of size-fractionated zooplankton collected near the Chatham Rise on the SalpPOOP (TAN1810) cruise. The cruise focus was on studying the impact of salp blooms and marine biogeochemistry and food webs. Stable isotopes were measured to investigate trophic positions of zooplankton. Samples were collected by bongo tows and size-fractionated through nested sieves (4-mm, 2-mm, 1-mm, 0.5-mm, and 0.2-mm). Samples were then analyze...
Show moreWe conducted double oblique zooplankton net tows from 200 m water depth to the sea-surface using a 0.7 m-diameter Bongo frame with paired 200-µm mesh nets, equipped with two General Oceanics flow meters to measure the filtered volume and a temperature-depth recorder. A fraction of each tow was size-fractionated through nested sieves (4-mm, 2-mm, 1-mm, 0.5-mm, 0.2-mm), rinsed with isotonic ammonium formate, and stored for isotopic analyses. Samples were then dried, fumed with HCl (to remove calcium carbonate), packed in pre-combusted tins and analyzed for stable isotopes by isotope ratio mass spectrometer at the U.C. Davis Stable Isotope Facility.
