Origin and morphology of notches in carbonate cliffs and hillslopes [electronic resource] : implications for paleoclimate and paleohydrology (Bahamas, Puerto Rico, Guam) / Matthew A.

Features with a distinctive "c" shape known as notches exist on tropical rocky carbonate coasts, interpreted as bioerosion notches. Inland notches have been interpreted as fossil bioerosion notches from a previous sea level highstand. However, many of these inland notches have morphologies similar to exposed flank margin caves, and contain speleothems, suggesting a speleogenetic origin. Fossil bioerosion notches contain important information on past sea level position, but fossil notches of speleogenetic origin offer important paleohydrological information. Notches were examined on San Salvador Island, Bahamas； Isla de Mona, Greater Antilles； and Guam, Northern Mariana Islands. Statistically, all notches exhibited similar morphologies, while being visually distinguishable. It is apparent that lateral variability of the notch is important in discovering the genetic mechanism. The correct interpretation of fossil notches is important in understanding complex groundwater relationships on carbonate islands.
