Water column temperature measurements from 2017-2019 on coral reefs around the island of Mo’orea, French Polynesia

Abstract:

Water column temperatures were recorded around the island of Mo’orea, French Polynesia from September 2017 through March 2019. Three reef zones (fore reef, back reef, fringing reef) were sampled to help characterize environmental conditions affecting reef health and resilience, and to increase understanding of the factors that trigger viral outbreaks on reefs.

Methods & Sampling

Water column temperatures were recorded around the island of Mo’orea, French Polynesia from September 2017 through March 2019. Onset HOBO temperature loggers were deployed by divers at nine sites within three reef zones, and replaced at six month intervals. The average (mean) temperature per hour was calculated and is reported, but no calibration was done for individual sensors.

Reef zones are designated by their location with respect to the reef:
1) Fore = offshore or outside part of reef;
2) Back = inside of the reef crest; or
3) Fringing = adjacent to the shore.

Data Processing Description

BCO-DMO processing description:
- Separated latitude and longitude into individual columns
- Corrected the missing digits in year field (for 25,161 entries)
- Converted date and time fields to ISO date format (yyyy-mm-dd)
- Converted date nad time fields to UTC time zone
- Adjusted field/parameter names to comply with database requirements
- Added a conventional header with dataset name, PI names, version date

Instruments

Onset HOBO Pendant Temperature/Light Data Logger

Supplied Name: HOBO Pendant® Temperature/Light 8K Data Logger Part # UA-002-08

Supplied Description:

Onset HOBO temperature loggers were deployed by divers, but no calibration was done for individual sensors.

Instrument Type

Generic Name: Onset HOBO Pendant Temperature/Light Data Logger

Acronym: Onset HOBO Pendant Temp/Light

Generic Description:

The Onset HOBO (model numbers UA-002-64 or UA-001-64) is an in-situ instrument for wet or underwater applications. It supports light intensity, soil temperature, temperature, and water temperature. A two-channel logger with 10-bit resolution can record up to approximately 28,000 combined temperature and light measurements with 64K bytes memory. It has a polypropylene housing case. Uses an optical USB to transmit data. A solar radiation shield is used for measurement in sunlight. Temperature measurement range: -20 deg C to 70 deg C (temperature). Light measurement range: 0 to 320,000 lux. Temperature accuracy: +/- 0.53 deg C from 0 deg C to 50 deg C. Light accuracy: Designed for measurement of relative light levels. Water depth rating: 30 m.
