Description

YSI Flowthrough Data

Data are described in the following manuscript:
Kudela, R.M., Lucas, A.J., Negrey, K.H., Howard, M. McLaughlin, K. Submitted to Estuaries, Coasts, Shelf Science (October 2014).. Death from below: Investigation of inhibitory factors in bloom development during a wastewater effluent diversion

Methods & Sampling

Sampling and Analytical Methodology:
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.

Instruments

Fluorometer

Supplied Name: Turner Designs C3 fluorometer

Supplied Description:

Data collected on a G5 WaveGlider. Data are essentially raw, no processing other than calibration applied. Turner Designs C3 fluorometer equipped to measure chlorophyll fluorescence (460 nm ex/696 nm em; reported in fluorescence units), turbidity (850 nm ex./850 em.; units= NTU; Nephelometric Turbidity Units), and colored dissolved organic material (CDOM ; 325 nm ex/410-600 nm em.). Sensors were calibrated by Liquid Robotics (chl fluorescence = 1.0119 mg ml-1 Basic Blue 3; turbidity= 3000 NTU turbidity standard) as per Turner Designs recommendation.

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.
