Abstract

From 2017 to 2023, the offshore area nearby the Scoglio d'Affrica islet, located in the Northern Tyrrhenian Sea, has been surveyed and monitored after a violent fluid emission from a shallow-water mud volcano that caused an outburst rising 10 m above the sea surface. This transient phenomenon occurred very localized and short-lived. Assessing the complexity of this kind of event requires an integrated monitoring system, which allows us to characterize the seafloor morphology and recent dynamics through high resolution swath bathymetry and direct visual seafloor observation. These data allow also the identification of new features produced by recent seafloor dynamics and fluid seepage related to mud volcanism, obtaining insights on the temporal and spatial evolution of the seafloor morphology related to cold seeps in the area. In particular, the mud volcano responsible for the 2017 gas outburst is made up of two shallow water mounds characterized by different seafloor evolutionary records, including sediment consolidation, fracturing and variation in morphology and height, likely related to inflation/deflation processes as well as to the sediment reworking by wave action.

期刊介绍： Marine Geology is the premier international journal on marine geological processes in the broadest sense. We seek papers that are comprehensive, interdisciplinary and synthetic that will be lasting contributions to the field. Although most papers are based on regional studies, they must demonstrate new findings of international significance. We accept papers on subjects as diverse as seafloor hydrothermal systems, beach dynamics, early diagenesis, microbiological studies in sediments, palaeoclimate studies and geophysical studies of the seabed. We encourage papers that address emerging new fields, for example the influence of anthropogenic processes on coastal/marine geology and coastal/marine geoarchaeology. We insist that the papers are concerned with the marine realm and that they deal with geology: with rocks, sediments, and physical and chemical processes affecting them. Papers should address scientific hypotheses: highly descriptive data compilations or papers that deal only with marine management and risk assessment should be submitted to other journals. Papers on laboratory or modelling studies must demonstrate direct relevance to marine processes or deposits. The primary criteria for acceptance of papers is that the science is of high quality, novel, significant, and of broad international interest.
