Fig. 1

Modern and uppermost Pleistocene Texas shelf where living and drowned coralgal reefs are located. a Drowned banks along the south Texas shelf edge are shown as red dots. The Flower Garden Banks, living coralgal reefs 150 km south of Galveston Island, are displayed as green dots. Note that, with one exception, the drowned reefs are currently located between 70 and 80 m isobaths. b Uppermost Pleistocene south Texas shelf coastal systems at 20 and 17 ka20 (located in Fig. 1a by red rectangle), illustrate a shallow bay up to 35 m deep, isolated from the open ocean by a barrier island complex, on top of which the south Texas reefs (shown in red dots) were established during the early part of last deglaciation
