Description

Temperature, oxygen, pH, depth, and conductivity measured at 5 m depth at Hopkins Marine Station from 18 April 2013 to 14 June 2013.

Methods & Sampling

Dataset acquisition description

CTD (SeaBird model SeaCat 19Plus (SN 4210)) and pH sensor were deployed at the KFA site, Hopkins Marine Station (average depth = 5m). Added sensors:
-- Aanderra Oxygen Optode (model 4835, SN223),
-- Digital to Analog Converter model 3966 A/D adapter,
-- pH datalogger: Honeywell Model 07777D-06 Durafet III in-line pH electrode with Cap Adapter.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:
- added columns containing site name, lat, lon, and avg sensor depth (originally provided as header info on the spreadsheet);
- modified parameter names to conform with BCO-DMO naming conventions;
- converted original date/time to ISO8601 format;
- replaced "-999" with "nd" (no data).

CTD Sea-Bird SBE SEACAT 19plus

Supplied Name: SeaBird model SeaCat 19Plus (SN 4210)

Supplied Description:

CTD: SeaBird model SeaCat 19Plus (SN 4210)

Instrument Type

Generic Name: CTD Sea-Bird SBE SEACAT 19plus

Acronym: Sea-Bird SEACAT 19 Plus

Generic Description:

Self contained self powered CTD profiler. Measures conductivity, temperature and pressure in both profiling (samples at 4 scans/sec) and moored (sample rates of once every 5 seconds to once every 9 hours) mode. Available in plastic or titanium housing with depth ranges of 600m and 7000m respectively. Minature submersible pump provides water to conductivity cell.

pH Sensor

Supplied Name: Honeywell Model 07777D-06 Durafet III

Supplied Description:

pH datalogger: Honeywell Model 07777D-06 Durafet III in-line pH electrode with Cap Adapter

Instrument Type

Generic Name: pH Sensor

Generic Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH. The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+).
