Water Level Observations National Water Level Observation Network (NWLON) • Monitor water level, air and water temperature, wind speed/direction, barometric pressure. • Long-term data series to establish vertical reference system (datums) and trends 210 NWLON Stations Center for Operational Oceanographic Products and Services

  3. NWLON in Alaska 27 NWLON stations in Alaska* 10 of which located in the Arctic* Nationwide: 111 NWLON gaps along coasts; 3 in Great Lakes 32 gaps in Alaska, the majority (21) being in the Arctic *Including the Port Moller Station which was destroyed in a fire
