    • Multibeam sonar bathymetric data for the Miami Pockmark and Key Biscayne Pockmark

    Metadata Updated: September 12, 2025

    Multibeam sonar data showing the bathymetric survey of two offshore submarine sinkholes, Miami Sinkhole and Key Biscayne Sinkhole. A series of dives were performed to produce the bathymetric surveys using an autonomous underwater vehicle (AUV) with a multibeam-sonar. These data were collected between May 5-8, 2016 using a Bluefin B12 AUV equipped with a Imagenex MBDelta and an onboard calibrated Kearfott T-24 Inertial Navigation System (INS) aided by a (WAAS), 600 kHz RDI Doppler Velocity Log (DVL) and a Valeport sound velocity meter.
