Temperature and dissolved oxygen recorded two PME Mindot O2 loggers in the Florida Keys from 11-17 July 2017

Abstract:

This dataset presents the temperature and oxygen data recorded by the two PME Minidot loggers. The loggers were deployed July 11-17, 2017 in a subtropical inner shelf environment (Salinity: 35-36, temperature: 28-31°C) approximately 9 km south of Long Key in the Florida Keys (24° 43.52'N, 80° 49.85'W). The site was located at 9 ± 1 m water depth near the center of a large flat carbonate platform covered with coral sand. The instruments were installed on the 3OEC instrument at ~35 cm above the sediment-water interface.

Methods & Sampling

Two PME Minidot loggers were deployed July 11-17, 2017 in a subtropical inner shelf environment (Salinity: 35-36, temperature: 28-31°C) approximately 9 km south of Long Key in the Florida Keys (24° 43.52'N, 80° 49.85'W). The site was located at 9 ± 1 m water depth near the center of a large flat carbonate platform covered with coral sand. The instruments were installed on the 3OEC instrument at ~35 cm above the sediment-water interface.

The temperature and oxygen data are the data recorded by factory-calibrated loggers:
Sampling rate is 1 /min
Oxygen range is 0 to 150%
Oxygen Resolution 0.01 mg/L
Oxygen Accuracy of +/- 1 mg/L
Response Time Approximately 30 seconds for oxygen

Temperature Range 0 to 35 degrees C
Temperature Resolution 10 millidigrees
Temperature Accuracy +/- 0.1 degrees C

The method of data analysis is reported in Huettel et al. (2020).

Instruments

PME MiniDOT Logger

Supplied Name: PME Minidot O2 logger

Supplied Description:

PME Minidot O2 logger; Serial number 458147, 482789. Calibrations: factory calibrated.

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.
