Dissolved, inorganic nutrient data integrated with bottle data from R/V Endeavor cruise EN614 in May 2018 (NCEI Accession 0278339)
This dataset contains biological, chemical, optical, and physical data collected on R/V Endeavor during cruise EN614 in the North Atlantic Ocean and South Atlantic Ocean from 2018-05-07 to 2018-05-29. These data include Nitrite, O2 saturation, Oxygen in volts, PAR, SiOH_4, beam attenuation, conductivity, depth, dissolved Oxygen, fluorescence, nitrate plus nitrite, potential temperature, salinity calculated from CTD primary sensors, sigma-theta, sound velocity, water pressure, and water temperature. The instruments used to collect these data include CTD Sea-Bird SBE 911plus, LI-COR Biospherical PAR Sensor, Niskin bottle, Nutrient Autoanalyzer, Sea-Bird SBE 43 Dissolved Oxygen Sensor, Wet Labs CSTAR Transmissometer, and Wet Labs ECO-AFL/FL Fluorometer. These data were collected by Joseph Montoya of Georgia Institute of Technology and 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 2021-10-26.

EN614 Nutrients
Dataset Description:
Acquisition Description:
Hydrographic data and water samples were collected during casts with a CTD-rosette system (SBE11plus equipped with a fluorometer, transmissometer, oxygen sensor, and a PAR sensor).
Water samples for dissolved, inorganic nutrient analysis were collected in duplicate directly from Niskin bottles attached to the CTD-rosette system (listed above). Sampling tubes were rinsed with sample water three times before collection. After collection, one set of samples was placed in a fridge to be analyzed within 48hrs aboard the vessel while the duplicate set of samples was placed immediately in a freezer for later analysis. Analysis was completed on a Lachat Quikchem 8500 Series 2 nutrient analyzer, according to standard methods listed below:
PO4: 31-115-01-I
Si: 31-114-27-1-B
NO3/NO2: 31-107-04-1-A
NO2: 31-107-05-1-A
