2 U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 2 OceanWatch is part of the NOAA-NESDIS CoastWatch/OceanWatch program NOAA OceanWatch Mission - "to provide and ensure timely access to near real-time satellite data to protect, restore, and manage U.S. coastal and ocean resources and understand climate variability and change to further enhance society's quality of life”. NOAA OceanWatch – Central Pacific node

3 OceanWatch is part of the NOAA-NESDIS CoastWatch/OceanWatch program 2 types of nodes : -CoastWatch : serve regional products tailored for coastal needs -OceanWatch : serve basin-wide or global products NOAA OceanWatch – Central Pacific node U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 3

4 OceanWatch CP currently provides regional & global satellite oceanography data from ~ 16 sensors and several user-specific products Data is provided on web and data server portals via Live Access Server & THREDDS (Thematic Realtime Environmental Distributed Data Services) that allow users to select: -Area of interest -Time period(s) -Data visualizations -Data download in various output formats Web Address: http://oceanwatch.pifsc.noaa.gov NOAA OceanWatch – Central Pacific Current Remote Sensing Dataset Inventory U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 4
