Description: The Floating Kelp Linear Extent project is a statewide data synthesis project by the Nearshore Habitat Program at the Washington State Department of Natural Resources. Floating kelp (Nereocystis luetkeana and Macrocystis pyrifera) survey data is summarized to 1 km coastal segments, represented by the -6.1 m MLLW isobath, except in the San Juans where some offshore line segments represent the -12.2 m MLLW isobath to account for offshore kelp presence. This layer describes the most recent presence of floating kelp for each segment based on the best available data.

Copyright Text: This dataset is created and managed by the Washington State Department of Natural Resources, through the Nearshore Habitat Program. It integrates data from the Nearshore Habitat Program, the Northwest Straits Commission, the Suquamish Tribe, Samish Indian Nation Department of Natural Resources, and other sources.
