Description

This dataset contains subtidal temperature data from February 2016 to February 2017 at 2 depth strata (6 and 12-15 m depth) from 12 sites in the central Galápagos Islands, Ecuador (00.41100 S, 90.27525 W).

Methods & Sampling

Dataset acquisition description

Temperature was measured in degrees C, sampled every 10 minutes using Onset HOBO TidbiT V2 temperature loggers. Site names refer to locations and columns refer to the approximate depth of logger.

Data Processing Description

Dataset Processing Description

These data are raw temperature data obtained from loggers.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* "NA" values replaced with no data value 'nd' for "no data"
* site positions added from dataset: https://www.bco-dmo.org/dataset/628159
* "time" column was split into date and time columns as it contained both
* ISO formatted timestamp added from date and time values
* data version 2018-03-29 replaces data version 2017-12-21. In version 2018-03-29, the time zone of the local (UTC-6) date stamps are clarified (date-> date_local, time-> time_local). Added 6 hours from ISO_DateTime_UTC values so they now reflect the UTC times correctly.
