NOAA Global DART and Tide Gauge Data

NOAA's National Geophysical Data Center stewards the non-real time data resulting from the observational arrays for DART (Deep-ocean Assessment and Reporting of Tsunamis) and tsunami-capable tide gauges. The deep ocean tsunameters, DART, were developed by the NOAA Pacific Marine Environmental Laboratory for the early detection, measurement, and real-time reporting of tsunamis in the open ocean. Operational access to these data are through the National Data Buoy Center. NGDC is also the long-term archive for all NOAA coastal tide gauge data. NGDC is currently archiving all 1-minute water level data from the NOAA/NOS Center for Operational Oceanographic Products and Services (CO-OPS) and the 15-second data from West Coast/Alaska Tsunami Warning Center. In 2007, CO-OPS completed upgrades on tide stations to enable the collection and dissemination of 1-minute water level data.
