Map & style credits
ReefRadar’s ocean map adapts OpenFreeMap’s Positron style. We modified water, land, labels, and detail levels for bright and dark themes.

Seafloor shading
When you zoom in to regional level, seafloor shading comes from Esri World Ocean Base (GEBCO, NOAA, CHS, and other contributors). That layer only covers mid zoom levels; ReefRadar crossfades back to the vector ocean fill for close-up views so you never see Esri’s empty-tile placeholder.
