National Water Level Observation Network (NWLON) (NWLON)

Updated 2012-07-25

The NWLON is a network of long term stations whose fundamental purpose is to provide vertical control (tidal datums) that support a host of national requirements. In addition, the NWLON collects continuous water level data and provides observations and derived data products that support: marine transportation and navigation ( hydrographic charting surveys, shoreline mapping surveys, tide predictions, forecast water levels, real time observations, dredging projects, hazardous material spill response); global sea level rise studies, storm surge and tsunami detection and warnings, marine boundary determination (federal/state, state/private, state/state), coastal zone management activities, ecosystem restoration, and effective marine spatial planning. Main gaps: Gap analysis report completed in FY2008 identifying gaps based primarily on providing vertical (tidal datum) control. Largest gaps in Arctic region – gaps in data and information in Bristol Bay, Bering Sea, Bering Strait, Chukchi Sea, and Beaufort Sea areas.
