Washington State Department of Natural Resources, Nearshore Habitat ProgramThis image service shows historical floating kelp locations along the Washington Coast and Puget Sound. It combines nine map sheets that were originally published in 1912. They summarize field surveys from 1911-1912. The Puget Sound surveys were conducted by Rigg. The maps were scanned and georeferenced, and the image service is hosted by the Washington Department of Natural Resources.ArcGIS ImageMapLayerhttps://hub.arcgis.com/datasets/1512cc985caf4eb3bf0f2e7a7d542e26engState of Washington Geospatial Open Data PortalPublicWashington State Historical Kelp [Washington (State)]Web servicesWashington (State)Last Modified: 2024-07-02
