©2020 Biological and Chemical Oceanography Data Management Office.This dataset includes dissolved, inorganic nutrient data integrated with bottle data from R/V Endeavor cruise EN640 in June and July 2019.
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 Quickchem 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
