The Earth Observation EU funded Copernicus mission Sentinel program has driven the development of new space borne sensors, a new ground segment and improvement to the data processing chains. Of particular interest to oceanographers is the acquisition of high quality sea surface temperature data. In order to unsure data quality, the Copernicus funded TRUSTED project initiated by EUMETSAT, aims to deploy an independent fiducial reference network of over 100 Data Buoy Cooperation Panel (DBCP) compliant Surface drifters. This development has implied the metrological characterization of the High...

In order to improve persistence and acoustic capabilities of a Slocum underwater glider, the wings have been re-designed and a linear array of eight elements has been placed along their leading edges. In this configuration the lift/drag ratio has increased by about 15-20% with an angle of attack (AoA) of 4° with respect to the original wing configuration. The best directivity performances have been obtained for a sound signals frequency around 2 kHz. According to the literature review, this may be useful for cetaceans passive acoustic monitoring (PAM).

This article presents the hindcasts of Orbetello lagoon circulation in different scenarios starting from the XVIII° century. The main objective of this work has been the quantification of water exchanges between lagoon and sea during the centuries. The hindcasts are obtained by means of numerical simulations. The simulations have been conducted by means of a numerical model validated by using field measurements carried out in the present scenario. Once the model has been validated, the bathymetry has been changed according to the morphology of the different past scenarios and the water...

This paper describes the MAREGOT (MAnagement des Risques de l'Erosion cotière et actions de GOuvernance Transfrontalière) approach to evaluate hydro-mophodinamic behaviuos using different methods on embayed beach in eastern Liguria (Mediterranean NW). Project aimed at the joint prevention and management of the risks arising from coastal erosion in the cooperation area; It is strategic project of 2014 - 2020 INTERREG V Italy - France (Maritime). The research was composed by field surveys, coastal modelling and remote sensing; as a first step, investigation was conducted comparing two...

The potentialities of an integrated 3D remote sensing survey with the most diffuse techniques, i.e. photogrammetry from UAV, laser scanner and multibeam from survey boat, are enhanced. Such techniques are useful both to verify the state of conservation of maritime infrastructures from a structural point of view and to highlight the phenomena of erosion or accumulation of sediments at the base. The case study relative to the breakwater of the Porto Sole private tourist port and the seabed facing it along the Sanremo coast (Imperia, Italy) is shown. The produced 3D model at centimetric...

As technological advances nowadays allow for long-term, high-frequency deep-sea monitoring studies, the collected datasets are increasing in size and diversity. As a consequence, together with the need for larger-scale management, the issue of the standardization of data collection and treatment and the comparability between datasets of distinct sources is being raised. This study presents examples of data treatment steps followed, in order to ensure that the datasets collected during a period of 5 years by the Internet Operated Deep-sea Crawler “Wally" meet high quality standards and are...

Over the past years different activities related on marine ecosystems monitoring techniques have been carried out at OBSEA observatory. The OBSEA is a cabled observatory placed at 4 km from the coast of Vilanova i la Geltrú, Barcelona (Spain), and at 20 m depth, which has been in operation for more than 10 years. The special characteristics of the OBSEA platform (e.g. unlimited power supply, high bandwidth communication, and easy access) offers an extraordinary opportunity to develop and test different acoustic monitoring techniques. In this framework, many methods have been deployed and...

During the last days of October 2018 a very deep low pressure system from the west Mediterranean, generated a very strong southerly pressure gradient resulted in the most intense phenomena at the last decades relating to Liguria coasts, causing unusual widespread damages. In this study were presented the analysis and the description of the sea-storm dynamic occurred on 29 October 2018. During the event, over Ligurian sea (North Western Mediterranean) were observed strong, organized and stationary thunderstorms, storm wind gusts and an intense sea-storm, hitting the entire Ligurian coast...

The SINDBAD- Leisure and Boating Safety Navigation – project goal is the development of an advanced operational service to support navigation in a specific area. The first prototype covers the Ligurian Sea (a very busy touristic area in the North Mediterranean Sea) It develops an ICT Service Infrastructure to provide innovative intelligent automation functions and to develop customized services, accessible by your mobile device, for conducting a boat and avoiding any kind of risk ensuring the best degree of comfort.

HF-radar systems are commonly employed for detecting the upper sea currents. Nevertheless, the signal of such systems can be further post-processed for characterizing as well the wave characteristics, though this is a recent application whose reliability has not been yet exhaustively investigated. In this work, we evaluate HF-radar measures of significant wave height, wave mean period and incident direction against the outcomes of two numerical models previously validated. The comparison is developed in the Gulf of Naples (hereinafter GoN), taking advantage of three antennas placed in the...
