Temperature data loggers were deployed next to individual colonies of Acropora hyacinthus located in either patch or fore reefs of the Palau Archipeglo from November 2017 to January 2020. Multiple loggers were deployed on each reef (up to 5). Loggers were set to record water temperature every 10 minutes. Temperature data were trimmed at the very beginning and end of each recording so that all records have the same start and end point. Some records show missing data (labelled nd) because they were deployed at a later date or because they lost battery power towards the end of the deployment.

Location:
\nPatch and fore reefs of the Palau Archipelago, 7 N 134 E, depths ~0.5-6m
Issues:
\n
Some individuals have a small amount of missing data for timepoints due to a later deployment date or due to device malfunction. This is rare, but these individuals were included to increase the total dataset. Missing data can be removed by trimming the start and/or end date, or by removing individuals.
\n
Processing:
\n\u200b
\nRaw data were exported as .csv files from the HOBOware application. All individual records were aligned to the same timepoint and combined into one file using a custom script. The beginning and end of the combined data file was trimmed by eye to reduce the amount of missing data.

BCO-DMO Data Manager Processing Notes:
\n* Original files submitted (2017-2018_Palau_coral_temperature_data.csv, 2017-2018_Palau_coral_temperature_meta_data.csv) combined and modified for reuse purposes. Changes described here. The originally submitted files can be found in the "Supplemental files" section of this page.
\n* added a conventional header with dataset name, PI name, version date
\n* modified parameter names to conform with BCO-DMO naming conventions
\n* blank values in this dataset are displayed as "nd" for "no data." nd is the default missing data identifier in the BCO-DMO system.
\n* Added latitude, longitude, reef number, and reef type, and coral species columns by joining with site information dataset. Joined water temperature file with a separate site information file to add the columns using colony_tag as the key.
\n* Temperature columns unpivoted to transform the data from multiple temperature columns for each colony to one temperature column and an added column containing the associated colony tags.
\n* Added ISO_DateTime_UTC in ISO 8601 format YYYY-mm-ddTHH:MMZ by converting date and time provided in local time (Pacific/Palau).
\n
Data version 2:
\n* Data from 2018 to 2020 added to the dataset.
\n* Source files imported for data version 2: 2017-2020_Palau_coral_temperature_data_V2.csv
\n* The above source files was processed in the same way as version 1.
