Considerable mesophotic habitat (30–150 m) exists on the broad insular platform, and well-mapped linear coral habitat exists on submerged banks near the shelf edge south of St. Thomas11,13,14. Sample sites from 2010 (gray) ranged in depth from 6–43 m. In 2011 a subset of 2010 sites were visited weekly for five weeks bracketing spawning in August: Black Point (5–10 m), Flat Cay (15–22 m), and Grammanik Bank (35–40 m). Map created using ArcGIS 10.
