Tidal Seafloor Pressure
Tidal Seafloor Pressure sensors measure the force of the seafloor exerted by the weight of the overlying water and atmosphere with a focus on tidal pressure changes by measuring pressure shifts down to the millimeter. Real-time measurements provided by seafloor pressure sensors are of great importance because lunar tides, storms, and tsunamis strongly impact pressures at the seafloor and the flow of fluids into and out of the oceanic crust.
The seafloor pressure sensors are installed and connected to the Cabled Array infrastructure at the Oregon Slope Base Site, at the Axial Base Site, and at the Southern Hydrate Summit site.
