 "description": "<DIV STYLE=\"text-align:Left;\"><DIV><DIV><P><SPAN><SPAN>This georeferenced image is a 2 meter resolution backscatter mosaic that was collected aboard the NOAA Ship Nancy Foster during the 20-08 mission. Backscatter is the measurement of relative intensity of the seafloor and is used to delineate benthic habitat types (hard vs. soft). The seabed elevation and acoustic imagery data (backscatter) were collected using multibeam echosounders (MBES). The data were processed and corrected for motion, sound speed, and other major artifacts before assessment. The corrected bathymetry base surface will be used to interpret the seafloor topography habitat types and extend the range of existing habitat map products that were created by manual interpretation of satellite imagery. The acoustic imagery (backscatter) aspect of the data will help further this interpretation.  High backscatter intensity can indicate coarse sediments or hard surfaces.  Low backscatter intensity can indicate softer sediments. <\/SPAN><\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
