In situ temperature data from August 2019 to May 2020 from one HOBO temperature logger deployed at Emerald Reef in Southeast Florida, USA

Abstract:

This dataset contains in situ temperature data from August 2019 to May 2020 from one HOBO temperature logger deployed at Emerald Reef at 7.8 meters depth in southeast Florida. Coral cores were collected from this reef and underwent experimental heat stress. In situ temperature data were used to inform seasonal temperature variation on this reef. The publication based on these data is Buzzoni, et al. (2023) (DOI: 10.1007/s00338-023-02428-x).

Methods & Sampling

As part of this study, coral cores were collected from tagged colonies of three coral species in either April 2019 or October 2019 from Emerald Reef in Southeast Florida, USA. Cores were then maintained in aquaria in the Marine Technology and Life Science Seawater complex at the University of Miami's Rosenstiel School of Marine, Atmospheric, and Earth Science and subjected to experimental heat stress. See related dataset for results fo the qPCR assays conducted as part of the heat stress experiments (https://www.bco-dmo.org/dataset/918220).

At the Emerald Reef site, a temperature logger (Onset HOBO U22-001 Pro v2) was deployed at 7.8 meters depth by hammering a rebar stake into the reef substrate, then securing the logger around the rebar close to the benthos using zipties. The logger was deployed from August 2019 to May 2020. These in situ temperature data were used to inform seasonal temperature variation on this reef.

BCO-DMO Processing

- Imported original file "temperature_HOBO.csv" into the BCO-DMO system.
- Converted the original date and time columns into a single date-time column in ISO 8601 format (Local time (EST))
- Added a date-time column for UTC times zone in ISO 8601 format.
- Converted the longitude values from positive to negative (to indicate West direction).
- Renamed fields/columns to comply with BCO-DMO naming conventions.
- Saved the final file as "918364_v1_fl_reef_temps.csv".
