   PI-Notes:
 
   The underway fluorescence data were recorded about every four minutes
   using a Turner 111 fluorometer equipped with a flow-through door and
   our own underway logging system.  The instrument was shut down while
   on station.  The data were manually calibrated to discreet surface
   chlorophyll measurements in segments determined by the  times of
   fluorometer cleanings, as well as any changes in water mass that might
   have affected the calibration.  Quality control consisted of range
   checks and removal of any readings which were obviously
   bubble-contaminated.

Instruments

Fluorometer

Supplied Description:

Sharon Smith's Turner Designs fluorometer plumbed to the ship's SAIL system.

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

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.
