What is SHOALS (Scanning Hydrographic Operational Airborne Lidar Survey)?
SHOALS (Scanning Hydrographic Operational Airborne Lidar Survey) meaning SHOALS is a laser-based scanning LIDAR bathymeter which collects high-resolution bathymetric data in shallow, offshore areas. Map products provide a view of sea-floor topography. In areas with coral reefs, this includes not only the top surface of the reef but also associated channels and sand flats
SHOALS imagery of the South Moloka’i reef tract shows the position of a distinctive channel that crosses the reef and a large hole in the reef. The large hole is shown below in oblique view. The origin of features such as this one is being investigated by USGS scientists. (Photo: U.S. Geolgical Survey)
