IOOS.us National Data Portal
IOOS data comes from a variety of technologies or data collection systems. While types of data available through any one of our 11 regional associations may vary depending on the local area, the national IOOS data products include data collected from buoys, high frequency radar systems and gliders. Modeling teams across regional associations also create data products including physical and environmental models of coastal systems.
IOOS data can be accessed through a variety of access services and tools through IOOS interactive maps, Data Assembly Centers (DACs), and individual Regional Association portals. This data access page provides an overview of all these services and tools as well as links to data usage demonstrations for scientists and managers looking to analyze data using various programing languages (Python, Matlab, R, etc).

The IOOS Catalog
The IOOS Data Catalog is the master inventory of IOOS DMAC datasets and data access services. Users of the Catalog can do a plain text search to locate datasets of interest across the regions, and then connect to their associated data access services in their application of choice. The Catalog is powered by metadata, and allows users the ability to search for words or phrases within the metadata (eg. salinity observations) to locate relevant datasets. IOOS provides a number of data access service types, including Sensor Observation Service (SOS), OPeNDAP for gridded data and model output, and Open Geospatial Consortium WMS and WCS for use in GIS applications. Catalog users may vary in background and familiarity with the IOOS data access services; power users such as scientists, geospatial data analysts, or environmental managers may get the most from the Catalog, however tools to enable the casual user to visualize IOOS data from these services conveniently from within the Catalog are in the works.
The Environmental Sensor Map
The Environmental Sensor Map integrates regional, national, and global real-time (past 4-hours) data across the IOOS enterprise. Data from observing systems operated by IOOS Regional Associations and local data providers within these regional footprints can be viewed and downloaded through this map. The map connects to over 32,000 stations providing the latest information on oceanographic and meteorological conditions. Individual stations and sensors can be selected when zoomed in. Data is obtained through various SOS access points. Dynamic graphs provide overview statistics for individual sensors or regions. The primary users of this map include Federal, State, and local marine scientists, coastal resource managers, and the general public.
