Water column sonar data comes from the acoustic backscatter from the near-surface to the seafloor. It’s used to assess the ocean’s physical and biological characteristics including spatial distribution of plankton and fish as well as methane seeps and underwater oil plumes.

Those working to map methane seeps are finding great value in the Water Column Sonar Data map viewer, created by NOAA’s National Centers for Environmental Information (NCEI). Scientists from oil and gas industries use it to identify and access data for exploration survey analysis. Academic researchers use it to analyze various US regions for methane seeps.

The Water Column Sonar Data map viewer provides easy discovery of 33 terabytes of data in the archive and excellent query tools to help distill the data of interest. It offers file-level selection to ensure users get exactly the data desired. These capabilities have decreased the volume of data being transferred, allowing for a more efficient process. Now, users are able to test specific files against the algorithms and other workflows they are developing.

Combines various data sources including water column sonar tracks, raster navigational charts, and the ArcGIS Online Ocean basemap for visualization of available data and analysis.

Powerful query capabilities enable users to define their spatial and metadata filter criteria to access their data of interest.

Uses an ArcGIS dynamic map service to display the data in varying projections, with Web Mercator, Arctic, and Antarctic views.
