These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) or other software to display the distribution of a submerged bryophyte mat in Crater Lake, OR.

JPEG These data contain attributes automatically generated by ESRI ArcGIS software, defined by the source, and additional user-defined attributes for use in analysis or model development. These data represent an interpretation of the shallow and deep limit of the byrophyte map on the Wizard Island Platform in Crater Lake, OR Complete 0.5 meters 0.05 percent of the water depth. Depths corrected to mean lower low water datum. U.S. Geological Survey 200103 raster digital data Menlo Park, CA U.S. Geological Survey http://wrgis.wr.usgs.gov/dds/dds-72/index.htm online 2001 publication date dds-72 base material The moss distribution model is based on 2000 multibeam acoustic backscatter data as well as 23 line kilometers of lake floor video collected in 2006. The shallow and deep limit of the byrophyte mat was outlined based on low versus high backscatter intensity. The boundary was compared with the lake floor video observations as well as an empirical process that mapped the moss distribution based on bathymetry, backscatter and other derivative products. 2006 Peter Dartnell U.S. Geological Survey, Coastal and Marine Geology Physical Scientist mailing and physical address
