This dataset contains biological data collected on R/V Endeavor during cruise EN614 in the North Atlantic Ocean from 2018-05-07 to 2018-05-29. These data include 19-prime-butanoyloxyfucoxanthin, 19-prime-hexanoyloxyfucoxanthin, Gyroxanthin-Diester, carotene, chl - photosynthetic pigments, chl_tot, chla_tot_to_pigtot, chlorophyll c3, chlorophyllide a, chltot_to_cartot, depth, diadinoxanthin, diatoxanthin, divinyl chlorophyll a, divinyl chlorophyll b, fucoxanthin, monovinyl chlorophyll a, monovinyl chlorophyll b, neoxanthin, photoprotective carotenoids, photoprotective carotenoids:total carotenoid, photosynthetic carotenoids, prasinoxanthin, total carotenoids - photoprotective plus photosynthetic, violaxanthin, and zeaxanthin. The instruments used to collect these data include High Performance Liquid Chromatograph. These data were collected by Ajit Subramaniam of Lamont-Doherty Earth Observatory as part of the "Collaborative Research: Impact of the Amazon River Plume on Nitrogen Availability and Planktonic Food Web Dynamics in the Western Tropical North Atlantic (Amazon River Plume Nitrogen)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-04-30.

Supplemental Information
Acquisition Description:
The samples were collected using a CTD rosette and an appropriate volume of water was filtered through a 25mm GF/F filter soon after collection. The filters were then stored in liquid nitrogen until analyzed. The analysis and duplicate filter precision details as well as calibration details are provided in may18atl_HPLC_readme.pdf . The samples were run at NASA GSFC by Crystal Thomas.

The diagnostic pigments were measured using High-performance liquid chromatography as detailed in Van Heukelem and Thomas (2001) and Hooker et al (2005).

The HPLC used for pigment analysis is an Agilent RR1200 with a programmable autoinjector (900 ul syringe head), refrigerated autosampler, degasser, and photo-diode array detector with deuterium and tungsten lamps. The HPLC is controlled by Agilent Chemstation software. The 4.6 x 150 mm HPLC Eclipse XDB column (Agilent Technologies, Palo Alto, CA) is filled with a C8 stationary phase (3.5 um stationary phase); the mobile phase consists of a linear gradient from 5-95% solvent B over the 27 minutes, for which solvent A is 70 parts methanol, 30 parts 28 mM tetrabutylammononium acetate (pH 6.5) and solvent B is methanol. The column temperature is 60 C and the photo diode array detector is set to plot chromatograms at 450, 665, and 222 nm to acquire visible absorbance spectra between 350 and 750 nm.
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
