LoCOS-wave: a low cost open source pressure gauge for measuring sea waves

Sea wave observation have been traditionally very expansive, for this reason we have developed a prototype of low-cost do-it-yourself wave gauge. This device measures the bottom sea pressure and retrieve the wave parameters from its Fourier spectrum. The wave parameters estimated with our device are comparable with those obtained from a commercial tide gauge obtain. For this reason, we consider that our device could be useful to perform sea waves measuring experiments obtaining high quality data at a much lower cost.
