Pockmarks in the Ibiza Channel and Western End of the of the Balearic Promontory (Western Mediterranean) revealed by Multibeam Mapping.
Pockmarks ranging in width from <10 to 700 m, and with reliefs of 2 to 55 m were discovered in the Ibiza Channel and on the Balearic Promontory, Western Mediterranean, during a multibeam survey. In the Ibiza Channel the larger structures are found within a field of small craters less than 10 m wi...

| Sumario: | Pockmarks ranging in width from <10 to 700 m, and with reliefs of 2 to 55 m were discovered in the Ibiza Channel and on the Balearic Promontory, Western Mediterranean, during a multibeam survey. In the Ibiza Channel the larger structures are found within a field of small craters less than 10 m wide and 5 m deep which give the seafloor an "orange peel" texture. The abundant 30 Ma–Present volcanic structures in the region suggests that most of the craters may have been formed by the escape of gases and associated waters via faults from a hydrothermal field beneath the surficial sediments. Others may be the result of neotectonism. |
