The Italian Fixed-Point Observatory Network (IFON) integrates well-established coastal and ocean infrastructures (buoys, platforms, moorings, mast etc.), most of them providing real-time multidisciplinary monitoring for a number marine atmospheric variables. Here, we describe the network characteristics then discuss an example its operation during cold spell winter 2012. One goals Flagship Project Ricerca Italiana per il mare (RITMARE) is to create common, validated IFON database able fulfil...
The Calabrian Arc is a narrow subduction-rollback system resulting from Africa/Eurasia plate convergence. We analysed the structural style of frontal accretionary wedge through multi-scale geophysical approach. Pre-stack depth-migrated crustal-scale seismic profiles unravelled overall geometry subduction complex; high-resolution multi-channel and sub-bottom CHIRP profiles, together with morpho-structural maps, integrated deep data constrained fine structure wedge, as well deformation...
OpenSWAP is a class of innovative open architecture, low cost autonomous vehicles for geological/geophysical studies shallow water environments. Although they can host different types sensors, these were specifically designed geophysical surveys, i.e., the acquisition bathymetric and stratigraphic data through single- multibeam echosounders, side-scan sonars, seismic-reflection systems. The main characteristic their ability following pre-defined routes with high accuracy under acceptable...
A fundamental requirement in the new generation of high resolution Cosmic Microwave Background imaging experiments is a strict control systematic errors that must be kept at μK level final maps. Some these are celestial origin, while others will generated by periodic fluctuations satellite environment. These environment instabilities cause measured signal output thus generating correlated effects reconstructed In this paper we present an analytical study impact on sky maps produced Planck...
The Lake of Cavazzo is a natural, lacustrine basin in the Friuli-Venezia Giulia region (NE Italy), which occupies fluvio-glacial suspended valley Tagliamento river, at southern front Alpine chain. lake formed after melting major glacial tongues end Last Glacial Maximum, and has been affected recent years by natural anthropogenic events, with economic, cultural environmental consequences. According to local witnesses, environment changed dramatically 1950s, when was connected hydroelectric...
A major explosion occurred on 30 June 1908 in the Tunguska region of Siberia, causing destruction over 2,000 km 2 taiga; pressure and seismic waves detected as far 1,000 away; bright luminescence night skies Northern Europe Central Asia; other unusual phenomena. This “Tunguska Event” is probably related to impact with Earth a cosmic body that exploded about 5–10 above ground, releasing atmosphere 10–15 Mton energy. Fragments impacting have never been found, its nature (comet or asteroid)...
Sandy beaches and the nearshore environment are dynamic coastal systems characterized by sediment mobilization driven alternating stormy mild wave conditions. However, this natural behavior of can be altered defense structures. Repeated surveys carried out with autonomous surface vehicles (ASVs) may represent an interesting tool for studying dynamics testing effects mitigation strategies against erosion. We present a one-year experiment involving repeated stratigraphic morpho-bathymetric...
The 1908 June 30 Tunguska Event (TE) is one of the best studied cases cosmic body impacting Earth with global effects. However, still today, significant doubts are casted on different proposed event reconstructions, because shortage reliable information and uncertainties available data. In present work, we would like to revisit atmospheric fragmentation Cosmic Body (TCB) by taking into account possibility that a metre-sized fragment could cause formation Lake Cheko, located at about $9$~km...
Newly collected morphobathymetric and seismic reflection data from the Valli di Comacchio coastal lagoons, south of Po River delta (Northeast Italy), combined with historical, remote sensing, geodetic highlight a complex geological evolution during Holocene, strongly affected by anthropic control. All allowed us to define present-day depositional environment lagoons reconstruct their recent (late Pleistocene/Holocene) geo-history. We focused on effects impacts in modifying pristine...
The present dataset was collected to evaluate the environmental stressors on a lacustrine basin in Eastern Alps of glacial origin that has been affected recent years by natural and anthropogenic events such as construction hydroelectric power plant series strong earthquakes during 1976-1977. We sediment cores different sites from lake margins depocenter performed multiproxy analysis sample highlight stratigraphy major changes occurring at decadal scale (Polonia et al., [1]). integrated...
The study of the marine coastal areas is great importance, for both protection and management environment. Due to always increasing anthropic pressure, availability real time model data can be critical decisions, expecially during emergencies In addition, time-series observation points necessary proper problem setting tuning models knowledge-based systems. We present some experience Real Time transmission handling from stations platforms, aiming toward a better integration into an Observation System.
Abstract In a recent paper, Rogozin and coauthors present morphologic/seismostratigraphic study of two small lakes, Lake Zapovednoye (LZ) Peyungda (LP), located 50‒60 km east from the alleged epicenter 1908 Tunguska Event (TE), large explosion believed to have been caused by an extraterrestrial impact. Data presented in that paper suggest similar (although not specified) origin these lakes Cheko, close TE epicenter. This led et al., question impact crater whose depression was interpreted...
The acquisition of marine seismic data is often affected by noise that introduces spurious signals. Due to the length receiver streamer, bad weather conditions can produce low‐frequency, high‐intensity incoherent and/or spikes be difficult remove means conventional mathematical filters. In this paper we present two Fortran routines suitable locate and in low very frequency ranges suppress spikes. These are designed run without user interaction once processing parameters selected. Both simple...
