The Ocean Research and Development Organization and others have developed a unique method to improve the accuracy of long-term seawater temperature prediction by attaching water temperature sensors to sea turtles and collecting data.
Predicting changes in seawater temperature is important for long-term forecasts of weather, and we measure the sea surface temperature with artificial satellites or measure buoys at different depths, but there is insufficient data The current situation is that accurate prediction is difficult.
Research groups such as the Japan Agency for Marine-Earth Science and Technology have installed water temperature sensors on the shells of five sea turtles that came to the beach for spawning on the Indonesian coast.
The sensor measures the water temperature at each water depth, and when it comes to the surface of the water, it is configured to send data via an artificial satellite. The sea turtle moves up to 1000 km or more up to a depth of 250 m after measuring for about 3 months. I was able to collect the data.
As a result of calculation with this data added, it was possible to greatly improve the accuracy of prediction of seawater temperature after 3 months in the waters around Indonesia, and to be close to the actual change in seawater temperature.
The sensor was designed so that sea turtles would not get in the way of feeding and would come off naturally within two years and were installed with special permission, so the group will continue to acquire data in the future. I want to establish a method.
Dr. Takeshi Doi, Japan Agency for Marine-Earth Science and Technology, said, “It's an unprecedented technique, but the accuracy has improved dramatically. We want to connect it to accurate long-term forecasts of weather in the future.”
