Geometry Type: esriGeometryPolygon

Description: This GIS layer is a database of the nearshore habitats in Kachemak Bay. It is focused on intertidal areas other than salt marshes. The data were gathered during an extensive field effort that began in 2002 and ended in 2004. With the use of field data and aerial photos collected in 1996, homogeneous alongshore segments (10-100 meters in length) were delineated and divided into four intertidal zones: low, low-mid, high-mid and high. Intertidal zones were delineated at 4 foot vertical intervals, starting with the low zone at the mean low tide line. Mapping occurred only at times when the tide was lower than plus two feet, so all zones would be visible during data collection. Within each intertidal zone, the physical components of the habitat were characterized by using indices of geophysical variables. The presence or absence of common biological communities was also noted. The GIS data and the report summarizing this effort can be downloaded from this University of Alaska, Anchorage website: https://accscatalog.uaa.alaska.edu/dataset/kachemak-bay-intertidal-habitat
