Time series surface total alkalinity, water temperature and salinity measured using an autonomous, automated total alkalinity titrator installed at the University of New Hampshire's Coastal Marine Laboratory (CML) in the Great Bay estuary along the New Hampshire coast from 2016-05 to 2019-11 (NCEI Accession 0245461)

This dataset contains data measured using an autonomous, automated total alkalinity titrator installed at the University of New Hampshire's Coastal Marine Laboratory (CML). The CML is located at the outlet of the Great Bay estuary along the New Hampshire coast. Hourly data were measured from the lab's continuous seawater supply, located approximately one meter off the bottom. In addition to total alkalinity, salinity and water temperature data are included. Temporal data coverage runs from May 2016 to November 2019, although there are substantial data gaps, in particular from April 2018 until March 2019 due to a fire and subsequent repairs to the CML building. This effort was part of the NOAA Ocean Acidification Program (OAP) and Ocean Technology Transfer Project grant entitled "Tracking Ocean Alkalinity using New Carbon Measurement Technologies (TAACT)". Measurements of pCO2 at the CML site are available from the Northeastern Regional Association of Coastal Ocean Observing Systems: www.http://neracoos.org/datatools
