Imaging of Alaska’s approximately 82,000 km (49,700 mi) coastline began in 2001. Currently 70,735 km or 86% of the Alaskan coastline has been imaged. Go to Alaska’s ShoreZone website.

British Columbia

ShoreZone was pioneered in the 1980s and 1990s along the 37,619 km (23,375 mi) coastline of British Columbia. Go to the British Columbia ShoreZone website.


Washington’s 4,933 km (3,065 mi) coast was surveyed between 1994 and 2000. Washington’s ShoreZone Inventory describes physical and biological characteristics of intertidal and shallow subtidal areas along the state’s saltwater shorelines. Go to the Washington ShoreZone website.


ShoreZone imaging of the 1,750 km (1,087 mi) coast of Oregon was conducted in June, 2011. The Oregon imagery is web-posted to allow easy agency and public access. Mapped data (such as eelgrass, canopy kelps, sediment type, and other features) will also be web-posted. Go to the Oregon ShoreZone website.
