The sea sensors that have been developed are based on the same principle as the SM4 sensors. It's a cable with temperature sensors that measures the temperature, with the data published here on the website. The cable, however, reaches a depth of 15 meters, and the temperature sensors are spaced 2.5 meters apart. There is also a temperature sensor on the surface that measures the air temperature.

The graph sent by the sea sensor can be seen below. The x-axis shows the temperature at each sensor. The y-axis shows the depth of each sensor. There you can see that the bottom sensor is at a depth of 15 meters. T(°C) is the precise temperature at each sensor. dT(°.12h) is the change in temperature at each sensor over the last 12 hours.
