Genesis of a submarine sinkhole without subaerial exposure: Straits of Florida
Abstract
A sinkhole has been identified on side-scan sonar images and from near-bottom echo sounder data in the southern Straits of Florida in 575 m of water. Sinkholes are often thought to form exclusively in subaerial environments and for this reason have been used as indicators of sea level. This sinkhole exists within a Quaternary sediment apron in water depths too great to have been subaerially exposed by Neogene sea-level lowstands, thus indicating that sinkholes can develop within the submarine environment.
