Instrument: Fluorometer
A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.
Data collected from an underway mapping system using a YSI 6600v2 sonde (CTD) and Turner Designs PhytoFlash variable fluorescence meter. Data merged with GPS locations and binned to 1 minute intervals. The PhytoFlash data were blank-corrected with 0.2 µm filtered seawater but were not corrected for ambient irradiance.
