Title
AquaticsNearshore img SquaxinIs 2022 [Washington (State)]
Description
This aerial imagery mosaic dataset was collected on behalf of the Washington State Department of Natural Resources (WA DNR) during the summer of 2022 in order to map the extent of floating kelp canopies in Washington State. Areas covered include the northern outer coast of Washington, the US portion of the Strait of Juan de Fuca, North Puget Sound, the San Juan Islands, Saratoga Passage & Whidbey Island Basin, WA DNR managed aquatic reserves (Cherry Point AR, Cypress Island AR, and Smith & Minor Islands AR), Admiralty Inlet, Tacoma Narrows, and Squaxin Island. Aerial surveys were conducted during low-tide, slack-current conditions identified by WA DNR for kelp forest monitoring, with some exceptions. This imagery has four bands (Band_1=red, Band_2=green, Band_3=blue, and Band_4=near-infrared) and was collected at 6-inch resolution. Floating kelp is readily visualized using an NGB band combination (near-infrared, green, blue), but can also be seen in some places with standard RGB imagery (red, green, blue). Imagery from this project are distributed as compressed (lossy) MrSID files for accessibility and ease of visualization, and are not suitable for image classification and analysis. These mosaics are a subset of the imagery products generated by this project, please contact the WA DNR Nearshore Habitat Program about other products that are available. These data support WA DNR's statewide long-term monitoring goals by providing high-resolution and large-area visualization of floating kelp canopies. For more information and inquiries about products available at specific locations, contact Danielle Claar, WA DNR, Nearshore Habitat Program at: danielle.claar@dnr.wa.gov or nearshore@dnr.wa.gov.
