About
This dataset provides underwater temperature data in degrees Celsius, collected from coastal islands and submerged rocky reefs along the Santa Catarina coast in southern Brazil. The data was acquired at 20-minute intervals between December 2012 and July 2014. Temperature loggers were installed underwater by SCUBA divers and fixed to rocky reefs at various depths, specifically 5 metres and 12 metres for islands, and 22 metres for submerged reefs. Note that some depth readings are absent for certain locations due to equipment loss.
Columns
- Site: Represents the specific location where the temperature data was recorded. There are 9 unique sites, with "Ilha Deserta" and "Ilha da Gal" being the most frequently occurring.
- Latitude: The latitudinal coordinate of the data collection site, ranging from approximately 26.37° S to 28.45° S.
- Longitude: The longitudinal coordinate of the data collection site, ranging from approximately 48.33 to 48.71.
- Date: The date of the temperature reading, spanning from 17 December 2012 to 26 January 2015, though the primary collection period is noted as December 2012 to July 2014.
- Time of Sampling: The precise time when each temperature measurement was taken, with recordings occurring every 20 minutes.
- Temperature (°C): The measured underwater temperature in degrees Celsius. Values in the dataset range from a minimum of 14.4°C to a maximum of 29.3°C.
- Depth (meters): The depth in metres at which the temperature was recorded. Common depths include 5 metres, 12 metres, and 22 metres.
Distribution
The dataset is provided as a CSV file named
underwater_temperature.csv, with a file size of 28.1 MB. It comprises 8 columns and contains over 409,000 valid records. The dataset is considered static and is not expected to be updated.Usage
This dataset is ideal for time series analysis of marine temperatures. It can be used by researchers and analysts to study oceanic temperature fluctuations, assess coastal marine environments, and observe seasonal temperature patterns in the specified Brazilian region.
Coverage
- Geographic Scope: The data covers the Santa Catarina coast in southern Brazil, specifically encompassing seven coastal islands and two submerged rocky reefs. The coordinates are between 26°22’ S and 28°26’ S.
- Time Range: Temperature records were primarily acquired between December 2012 and July 2014.
- Data Availability Notes: Some depth measurements are absent for particular sites due to the loss of monitoring equipment.
