Typically the data loggers are used to verify seawater temperature proxies. An example of this is the long-lived molluscArctica islandica which is used by scientists to generate time-series using their growth rings. Tritonia’s temperature datasets can be used to match the modern growth rings against known temperatures. Another use is to deploy the loggers over a latitudinal range to generate temperature profiles against which scientists can compare the growth rates of subtidal kelp species in order to predict what the future impacts may be of warmer seas around the UK.
The data loggers monitor the changes in seawater temperatures at different depths, typically 10, 20 and 30 metres. Monitoring intervals on the long-term time series are set to either 10 or 12 minutes. Most of the data loggers used on the long-term monitoring have been deployed off the west coast of Scotland, but they have also been used on short-term experiments in the tropics and in both Polar Regions. The loggers are deployed in pairs just in case of any losses or failures.
Martin Sayer is Tritonia’s Managing Director and has used Tinytags since the mid-1990s when they were the first product that provided the capability of long-term temperature monitoring at low costs. He comments, “We have simply stayed with the product because of its reliability. The latest versions are easy to use and are very resistant to being used in such a challenging environment. They provide a reliable and cost-effective way of generating high quality subtidal temperature datasets.”
