Proposed Miami Impact Crater Identified as a Solutional Doline of Oolictic Limestone [PDF]
Journal of the Washington Academy of Sciences, Fall 2020, Volume
106, No. 3, 2020 This investigation addresses the discovery of a proposed impact crater located off the coast of Miami, FL under the North Atlantic Ocean. A preliminary analysis of bathymetry data obtained from the National Oceanic and Atmospheric Administration implied a morphology consistent with a complex crater produced by a hypervelocity impact event of ...
