About this map:

This map offers a look at the basic bottom structure of Guam's nearshore habitats, differentiated here in simple hardbottom vs. softbottom (unconsolidated sediment) categories. The geospatial data for the map are directly from the Benthic Habitat Atlas by Burdick, D. (2006). Overview, background information, and methodology used in creating these data are available at http://guammarinelab.com/coastal.atlas/index.htm.
