Description

Salinity measured at the Pivers Island Coastal Observatory (PICO) from 2010 to 2012.

Note: Salinity was not measured at all time points, thus, some dates have no data ('nd') in the salinity columns.

Methods & Sampling

Dataset acquisition description

Water was sampled using a 5 L niskin bottle centered at 1 m with a bottle length of 0.7 m. Salinity was measured using a calibrated handheld digital refractometer (Atago PAL-06S), using a refractometer (Vista A366ATC), or using a Guideline Portasal 8410A all according to manufacturer’s instructions and calibrated against known reference materials.

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:
- Created 'replicate' column and re-arranged data so that replicates are in rows, not columns.
- 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.

Instruments

Refractometer

Supplied Description:

Salinity was measured using a calibrated handheld digital refractometer (Atago PAL-06S) or using a refractometer (Vista A366ATC).

Instrument Type

Generic Name: Refractometer

Generic Description:

A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from Snell's law and can be calculated from the composition of the material using the Gladstone-Dale relation.

In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light, or any other radiation, propagates through that medium.
