Abstract:

During eggs experiments, the general conditions within the tanks were monitored using electrodes for temperature, pH and its millivolt output, salinity, and dissolved oxygen. Results are published in Preziosi et al (2017), Table 1.

Description

During the eggs experiments, the general conditions within the tanks were monitored using electrodes for temperature, pH and its millivolt output, salinity, and dissolved oxygen. Results are published in Preziosi et al (2017), Table 1.

Methods & Sampling

The sensors were a model 55 YSI dissolved oxygen meter and an Orion Four Star pH conductivity meter using a gel-filled model number 9107WMMD pH/ATC Triode. Each instrument was calibrated according to the normal manufacturer's instructions using off the shelf calibration solutions. During and following experiment 8, the pH electrode readings appeared abnormal and are likely invalid. The electrode pH was only used as a guide for the sampling crew.

Data Processing Description

BCO-DMO Processing Notes:

Instruments

Benchtop pH Meter

Supplied Name: Orion Four Star pH conductivity meter

Supplied Description:

Used with a gel-filled model number 9107WMMD pH/ATC Triode

Instrument Type

Generic Name: Benchtop pH Meter

Generic Description:

An instrument consisting of an electronic voltmeter and pH-responsive electrode that gives a direct conversion of voltage differences to differences of pH at the measurement temperature. (McGraw-Hill Dictionary of Scientific and Technical Terms)

This instrument does not map to the NERC instrument vocabulary term for 'pH Sensor' which measures values in the water column. Benchtop models are typically employed for stationary lab applications.

Conductivity Meter

Supplied Name: Orion Four Start pH conductivity meter

Supplied Description:

Used to measure the approximate salinities.

Instrument Type

Generic Name: Conductivity Meter

Generic Description:

Conductivity Meter - An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution. Commonly used in hydroponics, aquaculture and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.

Oxygen Sensor

Supplied Name: model 55 YSI dissolved oxygen meter

Supplied Description:

Used to measure dissolved oxygen in the experimental tanks.

Instrument Type

Generic Name: Oxygen Sensor

Acronym: Dissolved Oxygen Sensor

Generic Description:

An electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed
