$ATL24 data for Marathon, Florida, illustrating the automatic detection and processing of ICESat-2 bathymetry. The top panel shows the location of the ATL24 segment extending from Vaca Key Bight south approximately 4 km. The bottom panel shows the ATL24 bathymetry profile from the shoreline to depths of 12 m. Aqua points correspond to detected sea surface, blue to bathymetry, and white to low-confidence bathymetry. Refraction correction has been applied to all bathymetric points.$
