Description

Eelgrass Climate Impacts
Experimental conditions, growth and survival of eelgrass
pH Data - Date, Tank pH readings

Methods & Sampling

Dataset acquisition description

pH data were recorded using Cole Parmer 350 pH/ORP controller units and Oakton epoxy body pH electrodes (UX-35801-00) calibrated weekly to a precision of 0.01 pH unit using NBS buffers. Output signals (4-20 mA) from the pH controllers were recorded at 10 minute intervals using the same NI data logger system and LabView software system used for the temperature data.

Data Processing Description

Dataset Processing Description

pH - Mean daily values of pH for each tank were calculated from the 10 minute records and provided in this spreadsheet. 10 minute records of the processed data, along with raw data files are available from the PIs, upon request.

Instruments

pH Sensor

Supplied Name: Cole Parmer 350 pH/ORP controller units

Supplied Description:

Instrument Type

Generic Name: pH Sensor

Generic 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+).
