Description

Temperature, salinity, oxygen, and pH measured by SeapHOx.

Methods & Sampling

Time series data collected by Satlantic SeapHOx. Samples are collected from two locations (Gulf coast of Florida near St. Teresa (29.907912N, -84.504201E); VA Eastern Shore near Oyster, VA, (37.261789N, -75.815357E) and from two heights in the water column: 20 cm = pump 1 and 1.1 m = Pump 2.

Data Processing Description

BCO-DMO Processing:
- modified parameter names to conform with BCO-DMO naming conventions (removed spaces and units);
- combined two data files into one dataset.

Supplied Description:

Instrument Type

Generic Name: SeapHOx/SeaFET

Generic Description:

The SeapHOx and SeaFET are autonomous sensors originally designed and developed by the Todd Martz Lab at Scripps Institution of Oceanography. The SeaFET was designed to measure pH and temperature. The SeapHOx, designed later, combined the SeaFET with additional integrated sensors for dissolved oxygen and conductivity. Refer to Martz et al. 2010 (doi:10.4319/lom.2010.8.172).

The SeapHOx package is now produced by Sea-Bird Scientific and allows for integrated data collection of pH, temperature, salinity, and oxygen. Refer to Sea-Bird for specific model information.
