Tide and current monitoring stations on Egypt's Mediterranean coast for NIOF and NRIAG. Each station measures sea level three ways at once — acoustic, radar and submersible pressure — through an intake built to cancel waves, wakes and currents. Multi-Task Pro stations add a full weather suite.
SpaceEcho has deployed multiple tide and current monitoring stations across the Mediterranean Sea for government-affiliated scientific institutions in Egypt: the National Institute of Oceanography and Fisheries (NIOF) and the National Research Institute of Astronomy and Geophysics (NRIAG).

The challenge
Sea level at a harbour wall is never still. Surface waves, vessel wakes, ocean currents, marine biofouling (algae and microorganisms) and changes in water density all reach an ordinary tide gauge as measurement error. The institutes needed sea-level readings that stay accurate through all of them.
What we installed
Tide gauge stations from SpaceEcho's tide-gauge range, each built around two parts.
A stabilised seawater intake — a dual-wall intake pipe that damps wave-induced fluctuations, with a symmetrical double-conical orifice between parallel end plates at the inlet, keeping steady flow conditions inside the measuring pipe.
Three synchronised sea-level measurements — acoustic sensors measuring wave height by ultrasonic pulses, radar sensors unaffected by temperature or humidity, and submersible pressure sensors, running together so each confirms the others.
Multi-Task Pro stations — at selected coastal sites, tide monitoring combined with an anemometer, pyranometer, thermo-hygrometer and barometer in a single station.
NIOF and NRIAG receive sea-level data cross-validated by three independent technologies, with the errors from waves, wakes, currents and fouling removed at the intake. Where Multi-Task Pro stations are installed, coastal and weather data come from the same station.
