This dataset contains pH time series simultaneously recorded by 4 pH sensors. Two of them were SAMI-pH, and the other two were SeapHOx. Data interval was 15 min. These data were part of an inter-comparison of autonomous in situ instruments for ocean CO2 measurements under laboratory-controlled conditions at Scripps Institution of Oceanography in August of 2016. These data were published in Shangguan et al. (2022).
This study used sensors (see Instrument description below) with quality control bottle samples. For bottle sample data and bottle analysis description, see Dataset "Inter-comparison 2016: Bottle Sample TA pH DIC" https://www.bco-dmo.org/dataset/870368
Instrument description:
This dataset has data from two SAMI-pHs (Sunburst Sensors, LLC; p66 and p87) (Seidel et al., 2008), two SeapHOx sensors (SP020 and SP032) (Bresnahan et al., 2014).
pH data have an interval of 15 mins.
