Description

Water temperature measured at the Pivers Island Coastal Observatory (PICO) from 2010 to 2012. Note: Temperature was not measured at all time points, thus, some dates have no data ('nd') in the 'temp_bot' column.

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. Temperature was measured in duplicate using NIST traceable thermocouples (VWR#23609-232).

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

Niskin bottle

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

Water Temperature Sensor

Supplied Description:

Temperature was measured in duplicate using NIST traceable thermocouples (VWR#23609-232)

Instrument Type

Generic Name: Water Temperature Sensor

Acronym: Water Temp Sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

General term for an instrument that measures the temperature of the water with which it is in contact (thermometer).
