Description

Temperature data collected from loggers deployed at the Thalassia Experimental Network (TEN) sites.

Methods & Sampling

Dataset acquisition description

One logger was deployed at the initiation of the project, and continuously recorded temperature for the duration of the one-year subtidal caging experiment. The logger was cable-tied to a PVC post at the side of the array (next to the cages). Temperature readings were recorded every six minutes. Loggers were removed, replaced, and data were downloaded three times throughout the experiment.

Where logger data was unavailable (e.g. if a logger failed for an extended period of time), data was taken from nearby HOBO loggers that were unassociated with TEN. When no alternative HOBO loggers were available, data was filled in by accessing (NOAA) buoy temperature data, product of the National Data Buoy Center.

Data Processing Description

Dataset Processing Description

Data Processing: Data was processed in the R Statistical Software (R version 3.6.1 (2019-07-05)). All data files were merged and QA/QC'd to ensure proper and consistent formatting. All files were cleaned by omitting time periods where the loggers were removed from the water.

Problem Report: Due to logistical challenges, the replacement of loggers to the field was occasionally delayed at some sites, with no alternative data available. There are thus some gaps in the temporal coverage of recorded data at certain sites.

BCO-DMO Processing:
- added latitude, longitude, and full site names from the site cooridnates file provided to BCO-DMO;
- converted the latitude and longitude values from degrees-minutes-seconds to decimal degrees;
- formatted the date_time field to ISO8601 format.

Instruments

Onset HOBO Pendant Temperature/Light Data Logger

Supplied Name: HOBO Pendant Temperature/Light 64K Data Logger

Supplied Description:

HOBO Pendant Temperature/Light 64K Data Logger; Part #UA-002-64; Onset Computer Corporation

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.
