Detailed Description

The Pacific Ocean near Yaquina Head, Newport, Oregon, is shown as an example of a sea/ocean hydrographic feature. Source data are from the National Hydrography Dataset (U.S. Geological Survey, 2020), which is used to provide examples of hydrographic feature types but may not have the same density and other characteristics of elevation-derived hydrography.
