New Seismoacoustic Data on Shallow Gas in Holocene Marine Shelf Sediments, Offshore from the Cilento Promontory (Southern Tyrrhenian Sea, Italy)

چکیده
High-resolution seismoacoustic data represent a useful tool for the investigations of gas-charged sediments occurring beneath seabed through identification diagnostic intrasedimentary features associated with them. Acoustic blanking revealed shallow gas pockets in seismostratigraphic units inner shelf off Northern Cilento promontory. Six main were recognized based on geological interpretation seismic profiles. Large pockets, reaching lateral extension 1 km, are concentrated at depocenter Late Pleistocene–Holocene marine that limited northwards by Solofrone River mouth and southwards Licosa Cape A morphobathymetric interpretation, reported GIS environment, was constructed order to show morphological lineaments link them acoustic anomalies interpreted Sub-bottom chirp newly workflow assessed perform elaboration Seismic Unix software comparing improving previously processed profiles used Seisprho software. The these corresponding from offshore promontory basis an assessment geohazards could help plan mitigation region.

Semi-massive to massive sulfides with abundant late native sulfur were drilled in a shallowwater hydrothermal system in an island arc volcanic setting at the Palinuro volcanic complex in the Tyrrhenian Sea, Italy. Overall, 12.7 m of sulfide mineralisation were drilled in a sediment-filled depression at a water depth of 630 650 m using the lander-type Rockdrill I drill rig of the British Geologi...

The ‘scope for growth’ (SFG) tool was used to study the growth performance of cultivated populations of Mytilus galloprovincialis (Lmk., 1819) in an oligotrophic area of the Southern Mediterranean Sea. The study was carried out between 1993 and 1996 by using data from four seasonal oceanographic cruises and from growth experiments. Water samples were collected and analysed for total suspended m...
متن کاملHolocene Environmental Variability in Southern GreenlandInferred from Lake Sediments
Sediments from Qipisarqo Lake provide a continuous Holocene paleoenvironmental record from southern Greenland. Following deglaciation and glacio-isostatic emergence of the basin from the sea ∼9100 cal yr B.P., proxies of lake paleoproductivity, including biogenic silica and organic matter, increased markedly until 6000 cal yr B.P. and thereafter remained stable over the ensuing warm three mille...
