The ENEA Marine Environment Research Centre S. Teresa has been involved since the ‘70s in monitoring, analysis and comprehension of physical, chemical and biological processes in marine environment. The purpose of this work is to describe the recently-implemented metrological approach aimed to evaluate the uncertainty associated with measurement results obtained by a Conductivity-Temperature-Depth profiler (CTD), deployed during routine coastal campaigns in the Eastern Ligurian Sea, close to the Gulf of La Spezia area. Main effort of this work is focused on applying the standard framework...

The rising levels of carbon dioxide in the atmosphere are responsible for fundamental changes occurring in seawater carbonate chemistry. For both air and water, there is a pressing need to assure metrological traceability thus obtaining comparable measurement results on spatial and temporal scales. At INRIM several activities are carried out to establish the metrological traceability for carbon dioxide measurement results. Two primary methods, the gravimetry and the dynamic dilution, are used for the preparation of reference standards for composition which can be used to calibrate sensors...

Sea state knowledge has a key role in evaluation of coastal erosion, in the assessment of vulnerability and potential in coastal zone utilization and development of numerical models to predict its evolution. X-band radar measurements were conducted to observe the spatial and temporal variation of the seastate parameters along the littoral cell on Bagnara Calabra. We produced a sequence of 1000 images of the sea state extending offshore up to 1 mile. The survey has allowed to monitor the coastline, the directional wave spectra, the sea surface current fields and to detect strong rip currents....

The Calabria’s Ionian continental slope is deeply incised by canyons which are characterized by V-shape cross-sections in their upper parts and Ushape cross-sections in their terminal parts. These conditions are favorable, under seismic action, it may give rise to submarine landslides. In this study, we propose a 3D numerical modeling of tsunami waves generated by an underwater slump with “Geowave” software. The simulated gravity instability zone is near the “Venere 1” head Canyon situated close Cirò Marina coastal area. The availability of a detailed bathymetric map both with a good...

The ground penetrating radar geophysical method is a rapid, high-resolution tool for non-invasive investigation. Ground penetrating radar records microwave radiation that passes through the ground and is returned to the surface. The radar waves propagate at velocities that are dependent upon the dielectric constant of the subsurface. Higher frequency sources will offer greater vertical resolution of structure but will not penetrate as deep as lower frequency sources. A method to determine ground-penetrating radar GPR velocities consist of determines the relative dielectric constant ratio at...

The grain size analysis of marine sediments is considered as a basic tool in the marine environmental research. In particular, information on sediment characteristic is needed, for example, for studies on sediment contamination, ecology of benthic communities, seismic studies, remote sensing surveys, beach nourishment, etc. A critical review of the main methods used for sampling, measuring and classifying marine sediments is reported here. It was deduced that no ideal method in order to obtain the highest accuracy of data exists, but the choice of the most suitable one should be adapted to...

We report the standardized procedures, developed in the last fifteen years at the IAMC-CNR Petrophysical Laboratory, with the aim to obtain reliable High Resolution Petrophysical Properties (HRPP) correlation in marine and terrestrial sediment. In the frame of a multidisciplinary approach, and depending of used scale correlation (which can vary from centimetric to decimetric/metric), the correlated petrophysical parameters combined with high resolution seismic and geoelectric profiles interpretation, sedimentological and geochronological data, may be a powerful tools to give new insight in...

The ecology team of the Biology Department of the University of Bari has developed the MEMO (Marine Environment MOnitoring system) baited lander to explore the Mediterranean marine ecosystems. MEMO is equipped with 2 video cameras, a multiparametric probe and a current meter. It can work down to 1000 m in depth for 24 consecutive hours. From 2010, the MEMO lander has been deployed in some deep-sea sensitive and vulnerable habitats of the Mediterranean Sea, as part of national and international research projects. Data on the environmental parameters (depth, salinity, temperature and current)...

In this paper is briefly described an integrated system (hardware and software) for geotechnical measurement on submarine contaminated sediments, which permits to reduce the probability of human mistakes often made during manual operations and, to increase speed, accuracy, and productivity in laboratory tests. The software was developed in LabVIEW to permit the communication with different data acquisition platforms and to simplify an eventual software reconfiguration in the case of changes in laboratory procedures.

The most widespread acquisition methods for lakes and sea bottom geological data are ship-, ROV- or AUV-based; geophysical methods and the related instruments for morpho-bathymetric survey allow to characterize large areas, even at high depths, but with high costs. It is known that shallow waters can represent a limit for certain vessels and techniques, preventing the acquisition in the nearshore zone. To overcome the limits, i.e. to survey with high accuracy nearshore shallow waters with a low budget, we tested and tuned the “GeoDive” method that allowed us to survey two test sites,...
