These are digital renderings of maps of the dominant subtidal habitat structure in the shallow subtidal (1-5m depth) around Appledore Islands in the Isles of Shoals, Maine, USA. These renderings were derived from surveys by Dr. Art Borror (1982-1990) and later Drs. Jim Coyer and Jarrett Byrnes (2014) while at the Shoals Marine Lab by taking a boat around the island at low tide and visually examining the habitats through a bathyscope.

The maps were georeferenced and digitized by Kate Sheridan, Andrea Brown, and Tianna Peller. Jake Lawlor and Jarrett Byrnes then took the resulting shapefiles and cropped and aggregated the information into the maps shown here. For any additional questions contact Jarrett Byrnes.
