        abstract:  CO-OPS has been involved with tsunami warning and mitigation since the Coast and Geodetic Survey started the Tsunami Warning System in 1948 to provide warnings to the Hawaiian Islands. After the December 2004 Indian Ocean tsunami, CO-OPS was tasked to coordinate with the NOAA Tsunami Warning Centers in upgrading existing stations with new Data Collection Platform (DCP) and communications technology and with expanding the tsunami warning capabilities of the National Water Level Observation Network (NWLON). Work began in 2005 to upgrade 33 existing water level stations and install 16 new stations from the Pacific Ocean to the Caribbean Sea by October 2006. As of September 2006, all 33 upgrades are complete, as well as 15 of the 16 new installations. As of October 2006, the NWLON consist of 196 long-term water level stations along all U.S. coasts, including the Great Lakes, Alaska, Hawaii, the Pacific Ocean Island Territories, Puerto Rico and the U.S. Virgin Islands. The NOAA National Centers for Environmental Information (formerly National Geophysical Data Center) serves as the archive center for these data and provides the historical data to users.
        purpose:  Provide raw water level data on a 1 minute sampling frequency.

It is called a tidal datum when defined in terms of a certain phase of the tide. Tidal datums are local datums and should not be extended into areas which have differing hydrographic characteristics without substantiating measurements. In order that they may be recovered when needed, such datums are referenced to fixed points known as bench marks.

        operation:  (MI_Operation)
            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 coast and in the Great Lakes. CO-OPS installs and operates short-term water level stations in support of a variety of programs including hydrographic surveys, marine boundary determination, 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. 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. The 1 minute tsunami data is collected either from the Aquatrak acoustic or Paroscientific pressure sensor and is used to detect, notify, monitor tsunamis once an earthquake or a landslide is reported. The water level data is collected every 1 minute and averaged using special algorithm but the data is transmitted every 6 minutes via Geostationary Observing Environmental Satellites (GOES) utilizing special data collection platforms. These installations and recent upgrades allow NOAA tidal stations to become an integral part of the Pacific and Atlantic tsunami detection and warning network. CO-OPS also has developed a web page for providing the tsunami information to the NOAA's National Weather Service Alaska and Pacific Tsunami Warning Centers.
