Fieldwork occurred during low tide sequences in May-September 2002-2004. A total of 4,207 along-shore segments were mapped in Kachemak Bay: 1,527 segments in 2002, 902 segments in 2003, and 1778 segments in 2004. Approximately 95% (301 miles) of Kachemak Bay has been mapped. Segments are attributed at four separate intertidal zones: High, High-Mid, Low-Mid, and the Low zone. Attributes collected include: energy, slope, dynamism, grain size, beach use, and biological characteristics such as barnacles, algae, fucus, mussels, verrucaria, and kelp presence.
