Instrument: pCO2 Sensor

Dataset: 
SAMI-CO2 pCO2 and Temperature Mooring Time Series
Instrument: 
pCO2 Sensor
Instrument Short Name: pCO2 Sensor
Instrument Description:

A sensor that measures the partial pressure of CO2 in water (pCO2)

PI supplied instrument name: SAMI-CO2 pCO2
Dataset-specific description

During the deployment 2 separate ASIS Buoys were deployed, ASIS-1 & ASIS-2, upon each of which 2 SAMIs were attached. Each buoy had 1 SAMI-CO2 attached at 1 meter and 1 SAMI-CO2 attached at 5 meters depth. The SAMI-CO2 sampled on a 30 minute interval and a non-absorbing blank measurement was taken every 3.5 days. PAR was measured by a Li-COR LI-192 underwater quantum sensor (not calibrated). Oxygen data was obtained using a calibrated Aanderaa O­­2 sensor (model 4175). Both the PAR and O2 sensors were attached to a SAMI-CO2 sensor. There is no pCO2 record at 1 meter on ASIS-2.
