Description

Dissolved oxygen concentration, percent oxygen saturation, and atmospheric (barometric) pressure measured at the Pivers Island Coastal Observatory (PICO) from 2010 to 2012.

Note: Not all parameters were not measured at all time points, thus, some dates have no data ('nd') in the 'O2', 'O2sat', and/or 'bar_press' columns.

Methods & Sampling

Dataset acquisition description

Oxygen was measured optically in situ and atmospheric pressure was measured near the sea surface using a calibrated probe (YSI ProODO handheld meter) using the manufacturer's recommendations.

Data Processing Description

Dataset Processing Description

Quality Scores (qflag) as follows:
1 = excellent (no known issues),
2 = suspect,
3 = poor (known reason to suspect data).

BCO-DMO Processing Notes:
- Modified parameter names to conform with BCO-DMO naming conventions.
- Replaced blanks with 'nd' to indicate 'no data'.
- Separated date into month, day, and year columns.
