Description

This dataset contains subtidal temperature data from 2015 to 2016 at sites in the central Galapagos Islands, Ecuador at depths of 6-15 m.

Approximate sampling location:
Eastern Tropical Pacific, Galapagos Islands, Ecuador

Methods & Sampling

Temperature data collected by Onset Tidbit temperature loggers (http://www.onsetcomp.com/products/ data-loggers/utbi-001) at 10-minute intervals. Loggers were attached to subtidal rock walls at 6-15 m depth. The temperature loggers have an accuracy of 0.2 degrees C.

Data Processing Description

Data Processing:
Data are raw, with no processing.

BCO-DMO Processing Notes
- Generated from original .csv file: galapagos_temperatures_20150107-20150715.csv contributed by Franz Smith
- Parameter names edited to conform to BCO-DMO naming convention found at Choosing Parameter Name
- "time" header changed to "Date" since no times were included with the data
- Date reformatted to YYYYMMDD
- Added ISO Date format generated from Date and Time values
- Data version 10 Feb 2017 replaces version 03 Dec 2015 and includes more temperature deployments extending into 2016 and also includes data from additional sites.
- Data format updated to accommodate new data. Depth stripped from previous site names and added to new "depth" parameter to match new data.
- Data sorted so it can be viewed by site.
- Added two new deployments

Instruments

Onset HOBO TidbiT v2 (UTBI-001) temperature logger

Supplied Name: Onset Tidbit temperature logger

Supplied Description:

Temperature data collected by Onset Tidbit temperature loggers
(http://www.onsetcomp.com/products/ data-loggers/utbi-001) at 10 minute intervals. Loggers were
attached to subtidal rock walls at 12-15 m depth. The temperature loggers have an accuracy of 0.2
degrees C.

Instrument Type

Generic Name: Onset HOBO TidbiT v2 (UTBI-001) temperature logger

Acronym: HOBO TidBit v2

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

A temperature logger that measures temperatures over a wide temperature range. It is designed for outdoor and underwater environments and is waterproof to 300 m. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 or M-RSA Solar Radiation Shield). With an operational temperature range between -20 degrees Celsius and +70 degrees Celsius, the TidbiT v2 has an accuracy of +/-0.21 and a resolution of 0.02 degrees Celsius.

Parameters

Date and time formats are described in python strftime() syntax.
