The commercially available Sea-Bird SeaFET™
provides an accessible way for a broad community of researchers to study ocean acidification and obtain robust measurements of seawater pH via the use of an in situ autonomous sensor. There are pitfalls, however, that have been
detailed in previous best practices for sensor care, deployment, and data handling. Here, we took advantage of two
distinctly different coastal settings to evaluate the Sea-Bird
SeaFET™ and examine the multitude of scenarios in which
problems may arise confounding the accuracy of measured
pH. High-resolution temporal measurements of pH were obtained during 3- to 5-month field deployments in three separate locations (two in south-central Alaska, USA, and one
in British Columbia, Canada) spanning a broad range of
nearshore temperature and salinity conditions. Both the internal and external electrodes onboard the SeaFET™ were
evaluated against robust benchtop measurements for accuracy using the factory calibratio.....
