This map service includes seagrass presence from underwater surveys in the marine nearshore of greater Puget Sound. The surveys are made with underwater video as part of a monitoring program conducted by the Washington Department of Natural Resources. Attributes describe the seagrass species classified at each point along the linear survey with a nominal spacing between points of approximately 1 meter. The map service currently serves 2000-2015 data. More recent data (2000-2017) is available for download.
