This work aims to investigate the potential capabilities of an uncalibrated Multibeam Echosounder (MBES) in fish school detection, reporting an experience regarding an offshore gas platform in the Adriatic Sea If, on one hand, the Split beam Echosounder technology is traditionally used for the purpose of biomass evaluation , on the other hand recent improvements in Multibeam Echosounder MBES technologies and advancing in water column data processing have made possible to detect schools and obtain some relevant metric information, with the advantage that a wide surrounding environment could...

The synergic utilization of data from different sources, either ground-based or spaceborne, can lead to effectively monitor fishing activities in close proximity of managed areas, and help tackle the problem of global overfishing. To this end, the integration of spaceborne Synthetic Aperture Radar (SAR) data and cooperative Automatic Identification System (AIS) information has the appealing potential to provide a better picture of what is happening at sea by detecting vessels that are not reporting their positioning data (intentionally or not) and, on the other side, by validating ships...

Plastic debris are one of the most harmful product for the health of the marine ecosystem. Usually, they enter the oceans as macroplastics through river deltas and tend to aggregate with other materials, floating on the sea surface. With the time passing, the macroplastics tend to degrade in microplastic and enter in the marine life because of ingestion. A fast and precise detection of floating plastics is necessary for monitoring and saving the sea ecosystem. Recent studies have demonstrated how remote sensing (and in particular satellites) can be helpful in such detection. Moreover, in the...

Extreme weather events have significant impacts on human activities and related economy in coastal areas. In this scenario, the forecast of sea storms and sea level changes to mitigate the effects of waves on shores, piers and critical coastal infrastructures is a key but challenging goal. This objective can be effectively achieved using a synergistic approach that includes numerical models, in-situ data and remote sensing measurements. To this end, we investigated the atmospheric forcing data of the storm event occurred in the Ligurian Sea on 29-31 October 2018, which induced significant...

In this study, the potential of dualpolarimetric (DP) Synthetic Aperture Radar (SAR) data to observe atolls is addressed. The partial polarimetric information is exploited to both define the coastal profile and to classify the observed area. Experiments are undertaken on a fine resolution DP L-band ALOS PALSAR-2 SAR scene collected under horizontal linear polarization transmission over the Goidhoo Atoll belonging to the Maldivian Baa Atoll, that was selected as test site due its importance for the local ecosystem and the extraordinary value of its biodiversity. Preliminary results show that...

In this paper, the availability and reliability of a remote video monitoring system for offshore sea farming plants are studied. The scope of the system is to ensure a video surveillance infrastructure so to supervise breeding cages along with the fish inside them in order to contrast undesired phenomena like fish poaching as well as cages damages. The system is installed on a cage floating structure. It is mainly composed of an IP camera which is controlled by a Raspberry Pi Zero which is the core of the system. Images are streamed thanks to a 3G/4G dongle while the overall system is...

The present paper discusses relevant aspects related to hybrid attacks involving cyber warfare and electronic warfare in naval radar systems. It addresses how such attacks can be implemented, showing that Electronic Attacks (EA) can be used to remotely trigger a cyber threat hosted in a radar computational system. The concept is demonstrated through simulations where a template matching technique is used to acknowledge the EA and, thus, trigger the cyber threat. The results show the effectiveness of the technique as a tool for activating malicious code previously installed in a radar system.

This paper focus on the observation of critical marine environments, pointing out the difficulties that these kinds of dynamic, sensitive and fragile environments create for monitoring operations. The technological solutions adopted, through the use of robotic vehicles, and the operating procedures implemented are also described. The data acquired in two particular critical environments, the front of tidewater glaciers in Svalbard and an area in the northern Tyrrhenian Sea affected by submarine gas emissions allow us to identify and characterise phenomena strongly localised and requiring...

In the present paper, the EURAMET European Metrology Network for Climate and Ocean Observation (EMN ClimOcNet), established in 2019, is presented. The EMN is focused on three different thematic areas, among which is ocean observation and metrology for Essential Ocean Variables. The main goal of the network is to establish a solid, long-term, European infrastructure to enhance the cooperation between the metrological and the oceanographic communities, to support the global understanding of climate change and the sustainable use of the oceans. The structure and the objectives of the EMN are...

This work regarded the possible use of stable carbon isotopic ratio of CO 2 to monitor the influence of visitors in the Refectory of Santa Maria delle Grazie (Milan, Italy) which houses one of the most important paintings of Leonardo da Vinci, the Last Supper. Indoor air quality is of utmost importance to guarantee the appropriate preservation condition of the painting since the exposure of artwork and materials to gaseous and particulate pollutants emitted from either indoor or outdoor sources contributes to their decay. The results showed a good correlation between the isotopic composition...
