        abstract:  The Center for Operational Oceanographic Products and Services (CO-OPS) of the National Ocean Service (NOS), an organizational element of NOAA, operates and maintains a network of approximately 200 long-term National Water Level Observation Network (NWLON) stations as part of the National Water Level Program (NWLP) for the United States coasts and in the Great Lakes. CO-OPS also installs and operates short-term water level stations in support of a variety of programs including hydrographic surveys, marine boundary determination, tidal predictions, habitat restoration, dredging, climate change, and long-term sea level rise studies. The data collected and predictions derived are used to ensure safe,efficient, and environmentally sound maritime commerce, environmental assessment, and hazard mitigation. CO-OPS provides a set of water level products required by NOAA's National Weather Service (NWS) to meet flood and tsunami warning responsibilities. Included in this water level collection are preliminary 1-minute, preliminary 6-minute, verified 6-minute, verified hourly, verified highs and lows, verified daily means, and verified monthly mean water levels.
        purpose:  This data is available to the public for a wide variety of uses including scientific research and analysis.

          RecordType:  Station: The geographic location at which water level observations are conducted. Also, the facilities used to make those observations. These may include a tide house, tide (water level) gauge, tide staff, and tidal bench marks. See primary control tide station, secondary control tide station, tertiary tide station, and subordinate tide station.

                    aName:  Station Datum
            descriptor:  A fixed base elevation at a tide station to which all water level measurements are referred. The datum is unique to each station and is established at a lower elevation than the water is ever expected to reach. It is referenced to the primary bench mark at the station and is held constant regardless of changes to the water level gauge or tide staff. The datum of tabulation is most often at the zero of the first tide staff installed. For Geat Lakes and St. Lawerence River stations, Station Datum is equivalent to IGLD.

            description:  The Center for Operational Oceanographic Products and Services (CO-OPS) of the National Ocean Service (NOS), an organizational element of NOAA, operates and maintains a network of approximately 200 long-term National Water Level Observation Network (NWLON) stations as part of the National Water Level Program (NWLP) for the United States coasts and in the Great Lakes. CO-OPS also installs and operates short-term water level stations in support of a variety of programs including hydrographic surveys, marine boundary determination, tidal predictions, habitat restoration, dredging, climate change, and long-term sea level rise studies. CO-OPS collects current data as a part of the National Currents Observation Program (NCOP) at locations throughout the United States. The data collected and predictions derived are used to ensure safe, efficient, and environmentally sound maritime commerce, environmental assessment, and hazard mitigation. CO-OPS provides a set of water level and coastal current products. These include data and products required by NOAA's National Weather Service (NWS) to meet flood and tsunami warning responsibilities and a national network of Physical Oceanographic Real-Time Systems (PORTS) in major United States harbors.
