Instrument: YSI Sonde 6-Series
YSI 6-Series water quality sondes and sensors are instruments for environmental monitoring and long-term deployments. YSI datasondes accept multiple water quality sensors (i.e., they are multiparameter sondes). Sondes can measure temperature, conductivity, dissolved oxygen, depth, turbidity, and other water quality parameters. The 6-Series includes several models. More from YSI.
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.
