Climate change brings upon melting of the Arctic ice and rising sea levels, which can be further understood by the collection of data underneath the Arctic ice caps. A Long Term Underwater Sensor (LoTUS) has therefore been proposed to be deployed under the ice caps for collection of water current speed and direction, along with temperature readings. In the current study a method to compute the water current speed and direction is experimentally verified using an accelerometer and magnetometer, where the results indicate that it can be used for scientific data collection.
