Dataset-specific description

A 5-channel, continuous flow analyzer was used for dissolved nutrient determinations on the BIG RAPA cruise. Alpkem and Technicon AutoAnalyzer II™ components were used to measure phosphate, ammonium, nitrite, silicic acid and nitrate plus nitrite (N+N). A Keithley model 575 data acquisition system backed by analog strip chart recorders was used to acquire the data. Absorbance data was converted to concentrations using the OSU program NUTCALC.
