Backscatter group layer shows the measurement of relative intensity reflected from the seafloor and is used to delineate benthic habitat types (hard vs. soft). The relative intensity (backscatter) is a result of measuring the strength of an individual ping absorbing or reflecting off the seafloor during multibeam acquisition.<\/SPAN><\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "The purpose of the data is to support Florida Keys National Marine Sanctuary (FKNMS) benthic habitat mapping and research planning efforts for improved spatial and fishery ecosystem management.
