We maintain a network of temperature loggers in bays around the Irish coast. These ’Tidbit’ temperature loggers record temperature hourly at various depths at each site, providing a comprehensive time series of sea temperatures around Ireland. Temperature is invaluable in understanding the biology, chemistry and oceanography of our coastal waters.
Below is a map which shows the Bays in which the Temperature loggers are located (Hover over marker for information).
The table shows the most recent reading for each location. Click on the temperature value for a plot for the site or click on the site name to see raw data for the site.
The loggers are located mainly on aquaculture structures within bays and are maintained by the Marine Institute and local staff at the aquaculture sites. The loggers store the data on site and are downloaded regularly during routine visits of Marine Institute staff to the sites. Data is updated as frequently as possible. View our table of data available for each site.
Requests for data can be made through the data request system.
