ShoreZone is a coastal habitat mapping and classification system in which georeferenced aerial imagery is collected specifically for the interpretation and integration of geological and biological features of the intertidal zone and nearshore environment. The mapping methodology is summarized in Harney et al (2008). This interim data summary report provides information on geomorphic and biological features of 28,595 km of shoreline mapped in 2004-2010 surveys of Southeast Alaska. There is approximately 1,100 km of unmapped shoreline in Glacier Bay. The habitat inventory is comprised of 88,704 along-shore segments (units), averaging 322 m in length. Organic shorelines (such as estuaries) are mapped along 3,388 km (12%) of the study area. Bedrock shorelines (BC Classes 1-5) comprise 4,947 km (17%) of mapped shorelines. Of these, steep rock cliffs are the most common mapped along 3,682 km (13%) of the shoreline. A little less than half of the mapped coastal environment is characterized as combinations of rock and sediment shorelines (BC Classes 6-20): 11,747 km (41%). Sediment-dominated shorelines (BC Classes 21-
