Methods & Sampling

Dataset acquisition description

The sonde with sensors was deployed manually from a raft or other floating craft (e.g. Caddis Fly inflatable seat). The sonde was lowered at one meter intervals and, at each depth interval, the reading was allowed to stabilize before readings were transcribed from the handheld meter to a dive slate in the field. Following return to the laboratory, data on the dive slate were entered into a spreadsheet, a preliminary plot made, and any apparent erroneous data (e.g. density inversions) were double-checked for accuracy of transcription and corrected as necessary.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:
- added conventional header with dataset name, PI name, version date
- renamed parameters to BCO-DMO standard
- reformatted date from dd-Mon-yy to yyyy-mm-dd (ISO date format)
- replaced blanks cells with nd
- removed blank lines and unmatched quote ('); eg. isn't becomes 'is not'

Hydrolab Series 5 probes

Supplied Name: Hydrolab DS5

Supplied Description:

Dissolved oxygen, temperature, pH, chlorophyll fluorescence and salinity/conductivity were measured using a HydroLab DS5 Multiparameter Data Sonde (Hach Company, Loveland, CO, USA).

Instrument Type

Generic Name: Hydrolab Series 5 probes

Acronym: HydroLab DS5

Generic Description:

Multi-parameter probes that can measure from 12 (MS5) to 16 (DS5 and DS5X) parameters simultaneously. Measurements include temperature, depth, conductivity, salinity, specific conductance, TDS, pH, ORP, dissolved oxygen, turbidity, chlorophyll a, blue-green algae, Rhodamine WT, ammonium, nitrate, chloride, PAR and total dissolved gases. These probes can be deployed at depths up to 200 m and can be used in continuous monitoring programs.

Water Quality Multiprobe

Supplied Description:

Multiparameter water quality sonde measuring Temperature, Conductivity, Depth, pH, Oxygen Reduction Potential (ORP), Dissolved Oxygen (Clark Cell), Turbidity.

Instrument Type

Generic Name: Water Quality Multiprobe

Generic Description:

An instrument which measures multiple water quality parameters based on the sensor configuration.
