Abstract

This dataset contains a total alkalinity (TA) time-series measured by three identically designed SAMI-alks (Submersible Autonomous Moored Instrument for Alkalinity). Data was recorded at 1-hour intervals. 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).

Cite Dataset

This study used three SAMI-alks with measurement frequency at 1-hour intervals. See references for technical details of the instrument (Shangguan et al., 2022).
