The dataset contains the processed bottle files, i.e., depths and associated data collected electronically by the CTD, for all CTD casts during cruises KM1919 and KM1920, along with all nutrient data on casts from which it was collected. The nutrients include nitrate, nitrite, silicate, phosphate, and ammonium. The concentrations for all nutrients are in micromoles per kg as is the CTD oxygen concentration. These two cruises took place on the R/V Kilo Moana from September to October 2019 in the ...
Show moreData were collected CTD during cruises KM1919 and KM1920.
The CTD data has been reprocessed and aligned, and outliers have been removed. Nutrient samples were filtered (Sterivex 0.22um) before analysis and analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html). All data are considered preliminary.
Known Problems:
Calibration salinity samples analyzed using an AutoSal salinometer agreed with CTD sensor 0, but sensor 1 was significantly off. Consequently, salinity values and derived values (density, oxygen, oxygen saturation) were calculated only from sensor 0. Sensor 1 data not included.
