Each estuary was subdivided into three possible salinity zones between the head of tide and the seaward boundaries, based on annual-averaged and depth-averaged salinities. The three zones include a Tidal Fresh Zone (0 - 0.5 parts per thousand), a Mixing Zone (0.5 - 25 parts per thousand) , and a Seawater Zone (25 parts per thousand or greater).", "summary": "", "title": "NOS_StaticThreeZoneSalinityScheme", "tags": [ "salinity", "estuarine salinity" ], "type": "Map Service", "typeKeywords": [ "ArcGIS", "ArcGIS Server", "Data", "Map Service", "Service" ], "thumbnail": "thumbnail/thumbnail.png", "url": "", "extent": [ [ -97.7484664919344, 24.8355503084009 ], [ -80.3759536746217, 41.8907203670522 ] ], "minScale": 0, "maxScale": 1.7976931348623157E308, "spatialReference": "WGS_1984_Web_Mercator_Auxiliary_Sphere", "accessInformation": "National Ocean Service, Special Projects Office, NOAA", "licenseInfo": "", "portalUrl": "" }
