Seafloor Pressure is a measure of the force on the seafloor exerted by the weight of the overlying water column plus the weight of the atmosphere. Nano-resolution Bottom Pressure measurements are seafloor pressure measurements with very high sample rate and accuracy. This high resolution provides sufficient precision to enable the measurement of the rise and fall of the seafloor.
