Initial spores
Instrument: 
pH Sensor
Instrument Short Name: pH Sensor
Instrument Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH.  The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+). 

PI supplied instrument name: pH meter
Dataset-specific description

Specifically, spectrophotometric pH was determined as per SOP6. As described in Dickson, A.G., Sabine, C.L. and Christian, J.R. (Eds.) 2007. Guide to Best Practices for Ocean CO2 Measurements. PICES Special Publication 3, 191 pp.
