I’m looking for a technology to trek and detect the underwater movement of gravel (a stone) in real time. These gravels (stones) move along Dead Sea shoreline by longshore currents triggered by the wind.
The movement occur inside the hypersaline lake shallow water of the Dead Sea (1240 kg\m3 water density) at depth of 0-1.5m in a very energetic environment during storms.
For example if exists a small chip that can be injected into a stone and record its underwater rout (relative location) and be picked after a period of time or transmit location data to an antenna inside or outside the water (in a range of few meters) it can be very helpful for my research.
thank you very much
