“…MEDUSA is made up of four marine monitoring stations based on the CUMAS concept (Iannaccone et al, 2009(Iannaccone et al, , 2010. Each marine station consists of a buoy equipped with CGPS and connected by cable to a seafloor module hosting geophysical and oceanographic sensors ( Figure 3a).…”

“…Although observations of the deformations that have occurred on land are available since the Ancient Roman era and instrumental measurements have been performed since the beginning of the last century, no measurements were available until 2008 for the submarine part of the caldera. In 2008, a first step was taken to extend the monitoring network in the submarine sector of the caldera with the CUMAS marine platform (Cabled Underwater Multidisciplinary Acquisition System) deployed at a depth of about 100 m in the Gulf of Pozzuoli (Iannaccone et al, 2009(Iannaccone et al, , 2010. CUMAS is a special type of buoy, which has been termed elastic beacon buoy, connected by cable to a seafloor multisensor module, equipped with autonomous power supply and realtime wireless data transmission.…”

We present an assessment of vertical seafloor deformation in the shallow marine sector of the Campi Flegrei caldera (southern Italy) obtained from GPS and bottom pressure recorder (BPR) data, acquired over the period April 2016 to July 2017 in the Gulf of Pozzuoli by a new marine infrastructure, MEDUSA. This infrastructure consists of four fixed buoys with GPS receivers; each buoy is connected by cable to a seafloor multisensor module hosting a BPR. The measured maximum vertical uplift of the seafloor is about 4.2 ± 0.4 cm. The MEDUSA data were then compared to the expected vertical displacement in the marine sector according to a Mogi model point source computed using only GPS land measurements. The results show that a single point source model of deformation is able to explain both the GPS land and seafloor data. Moreover, we demonstrate that a network of permanent GPS buoys represents a powerful tool to measure the seafloor vertical deformation field in shallow water. The performance of this system is comparable to on‐land high‐precision GPS networks, marking a significant achievement and advance in seafloor geodesy and extending volcano monitoring capabilities to shallow offshore areas (up to 100 m depth). The GPS measurements of MEDUSA have also been used to confirm that the BPR data provide an independent measure of the seafloor vertical uplift in shallow water.

“…The Gulf of Pozzuoli represents the submerged part of the caldera and marine monitoring within and around the Gulf consists of four tide gauges and a Cabled Underwater Multidisciplinary Acquisition System (CUMAS), described below. INGV are also developing new marine monitoring techniques, such as underwater monitoring modules and geodetic buoys [Iannaccone et al, 2009[Iannaccone et al, , 2010De Martino et al, 2014a].…”

A new method to assess long‐term sea‐bottom vertical displacement in shallow water using a bottom pressure sensor: Application to Campi Flegrei, Southern Italy

et al. 2016

We present a new methodology using bottom pressure recorder (BPR) measurements in conjunction with sea level, water column, and barometric data to assess the long‐term vertical seafloor deformation to a few centimeters accuracy in shallow water environments. The method helps to remove the apparent vertical displacement on the order of tens of centimeters caused by the BPR instrumental drift and by seawater density variations. We have applied the method to the data acquired in 2011 by a BPR deployed at 96 m depth in the marine sector of the Campi Flegrei Caldera, during a seafloor uplift episode of a few centimeters amplitude, lasted for several months. The method detected a vertical uplift of the caldera of 2.5 ± 1.3 cm achieving an unprecedented level of precision in the measurement of the submarine vertical deformation in shallow water. The estimated vertical deformation at the BPR also compares favorably with data acquired by a land‐based GPS station located at the same distance from the maximum of the modeled deformation field. While BPR measurements are commonly performed in deep waters, where the oceanic noise is relatively low, and in areas with rapid, large‐amplitude vertical ground displacement, the proposed method extends the capability of estimating vertical uplifts from BPR time series to shallow waters and to slow deformation processes.

“…Moreover, the Digital Coast platform lacks a crowdsourcing approach that may become crucial for the creation of large, participative datasets. Some solutions have focused on the multidisciplinary approach only in regards to the instrumentation [16] and the methodologies [17,18], without widening the scale of the monitoring infrastructure. As far as we know, such a comprehensive approach as the one proposed in this paper has never been discussed before.…”

Abstract:In this paper, the authors describe the architecture of a multidisciplinary data acquisition and visualization platform devoted to the management of coastal environments. The platform integrates heterogeneous data acquisition sub-systems that can be roughly divided into two main categories: remote sensing systems and in situ sensing systems. Remote sensing solutions that are going to be implemented include aerial and underwater data acquisition while in situ sensing solutions include the use of Radio Frequency IDentification (RFID) tracers, Wireless Sensor Networks and imaging techniques. All the data collected by these subsystems are stored, integrated and fused on a single platform that is also in charge of data visualization and analysis. This last task is carried out according to the paradigm of Augmented Virtuality that foresees the augmentation of a virtually reconstructed environment with data collected in the real world. The described solution proposes a novel holistic approach where different disciplines concur, with different data acquisition techniques, to a large scale definition of coastal dynamics, in order to better describe and face the coastal erosion phenomenon. The overall framework has been conceived by the so-called Team COSTE, a joint research team between the Universities of Pisa, Siena and Florence.
