Bottle data and chemical analysis from Falkor cruise FK180624 in the Eastern Tropical North Pacific Ocean in 2018 (NCEI Accession 0278087)
This dataset contains biological, chemical, optical, and physical data collected on R/V Falkor during cruise FK180624 in the North Pacific Ocean from 2018-06-30 to 2018-07-13. These data include Ammonium, Nitrite, depth_bottom, dissolved Oxygen, fluorescence, nitrate plus nitrite, pH, salinity calculated from CTD primary sensors, total alkalinity (TA), and water pressure. The instruments used to collect these data include Automatic titrator, Chemiluminescence NOx Analyzer, and Spectrophotometer. These data were collected by Andrew R. Babbin and Ryan Woosley of Massachusetts Institute of Technology and Karen L. Casciotti of Stanford University as part of the "Solving Microbial Mysteries with Autonomous Technology (Microbial Mysteries)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-03-17.
The following is the text of the dataset description provided by BCO-DMO:
Acquisition Description:
The samples were taken using a 24-bottle CTD rosette with 12L bottles. Depths varied per station but were focused in the upper 1000m. 19 stations were sampled with 22 casts total.
Samples were drawn in order: pH, alkalinity, NH4, nutrients (NOx, PO4, NO2). pH, NH4, PO4, NO2 were measured within 3 hours of collection onboard. NOx were filtered (0.22um Sterivex) and frozen. NOx is generally a mean of 3 measurements. Alkalinity were poisoned with a saturated HgCl2 solution and preserved in 160mL crimped serum bottles.
