Understanding tidal flow is important for a range of maritime activities and environmental monitoring, such as search and rescue operations, shipping routes and coastal erosion. The Arctic Ocean tides are particularly difficult to understand, but a new tidal model produced using ESA satellite data may shed some light on what is happening in this remote area. In many areas of
