The northern and western sides form one continuous barrier reef, and the eastern side is another barrier reef.

The four mile wide lagoon has soundings from 15 to 20 fathoms (27 to 37 m) and abounds in detached coral patches.

It was named after Captain Daniel Ross of the Bombay Navy, one of the first surveyors of the area.

Captain Ross later became the East India Company's Marine Surveyor General in Calcutta.
