Description

Moored physical and chemical parameters measured by MiniDOT at El Rosario and Isla Natividad sites, Mexico.

Methods & Sampling

Dataset acquisition description

All instruments were mounted vertically on taut-line moorings. Instruments were deployed and recovered by scuba divers. Data were processed using vendor supplied software and quality controlled to remove bad data (salinity below 30 or above 40, temperature below 4 C or above 30 C, pressure < 1 m). No known issues or problems.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:
- replaced missing data/blanks with 'nd' (no data);
- replaced spaces with underscores;
- corrected the SN_Instrument column as Excel had erroneously incremented values in cells;
- changed date format of all Deployment_Date_Time_LT and Retrieval_Date_Time_LT values to yyyy-mm-dd_HH:MM;
- corrected erroneous location name in the Punta Prieta Buckets data per feedback from PI;
- renamed original date/time field of "Greenwich_Mean_Date_Time" to "Date_Time_LT" per feedback from PI.

PME MiniDOT Logger

Supplied Name: MiniDOT

Supplied Description:

Instrument Type

Generic Name: PME MiniDOT Logger

Generic Description:

The PME miniDOT logger is a submersible sensor designed to measure water temperature and dissolved oxygen concentration. Dissolved oxygen is measured by an optode that measures lifetime-based luminescence quenching of a thin membrane. The sensing foil contains a coating with a variable fluorescence depending on the oxygen concentration of the surrounding water. The miniDOT reports in milligrams per liter (mg/L) and logs all measurements to an internal SD card. Also featured is a temperature sensor and batteries. Data can be offloaded to a computer via USB cable. The logger has an accuracy of +/- 5 percent (+/- 0.3 mg/L) for oxygen, and +/- 0.1 degrees Celsius for temperature. Temperature range is 0 to 35 degrees Celsius, oxygen range is 0 to 150 percent saturation. Depth-rated to 300 meters.
