This data set contains the nutrient concentrations (phosphate-PO4, nitrite+nitrate-NO2+NO3, Silicon Tetraoxide-SiO4, nitrite-NO2, and ammonium-NH4), total chlorophyll a concentration, the concentration of coccoid cyanobacteria, photosynthetic eukaryotes, and diatoms, and the abundances of protists (dinoflagellates and ciliates) as both cells/ml and as micrograms C/L, and of phytoplankton genera as cells/ml from water samples collected using Niskin bottles during August and September 2014 as well as sample depth, position (latitude and longitude, date, station number, and temperature, salinity, and chlorophyll from fluorescence (raw and corrected) from the conductivity, temperature, and fluorescence sensors on the CTD package. More information regarding sample collection and the associated Conductivity, Temperature, and Depth (CTD) casts numbers can be found in the event log for this cruise. Raw chlorophyll from fluorescence values from the fluorometer on the CTD were corrected using a regression between extracted chlorophyll and raw chlorophyll fluorescence: Y=0.8942-0.0252 where X is the value from the WetLabs Fluorometer and Y is the corrected value in mg/m3 or μg/L.
