    Monitoring Soil Moisture in an Agricultural Test Site Using SAR Data: Design and Test of a Pre-Operational Procedure (2015)
    IEEE / Institute of Electrical and Electronics Engineers Incorporated
    Details
    Publication Date: 2017-04-04
    Description: An algorithm for pre-operational high resolution soil moisture mapping using Synthetic Aperture Radar (SAR) data is presented. It has been conceived to be inserted in the operational weather alert system of the Italian Department of Civil Protection. The Maximum A Posteriori (MAP) probability criterion is applied to retrieve soil moisture by inverting a forward backscattering model, and ancillary data such as optical images and land cover maps are also used to identify areas in which the retrieval can be carried out. The well-established semiempirical water cloud model is adopted to correct for the effect of vegetation on SAR data. In anticipation of the use of the algorithm in an operational system, in which the SAR-derived high resolution soil moisture product can be assimilated within weather prediction models or hydrological ones, an uncertainty index is associated to each estimate. The algorithm has been tested on a dataset consisting of ground data gathered for seven years (2003–2010) on an agricultural test site in Northern Italy and radar data provided by the C-band ENVISAT/ ASAR instrument. A comparison, performed at field scale, between estimated and in situ soil moisture data has shown that, by discarding the estimates with the largest uncertainty, the correlation coefficient can exceed 0.80 and the root mean square estimation error is less than 0.05 m /m . Moreover, the uncertainty index has turned out to be fairly correlated to the actual estimation error.

    Design and performance analysis of a piezoelectric generator by Von Karman vortexes for underwater energy harvesting (2015)
    North Sea Conference & Journal
    Details
    Publication Date: 2017-04-04
    Description: With the decrease in energy consumption of electronic sensors, the concept of harvesting renewable energy in human surrounding, using piezoelectric technology seems promising to feed small sensors in several environments. The aim of this paper is to design a piezoelectric generators, optimized for magnetic sensors, able to work under the sea or into rivers, which can work with natural water vibrations generated by solid-fluid objects interactions (Von-Karman Vortex) and then to test the effectiveness of the device developing an electronic board to analyze the behavior of the generator.

    A geochemical and stable isotope investigation of groundwater/surface-water interactions in the Velenje Basin, Slovenia (2015)
    Springer-Verlag Germany
    Details
    Publication Date: 2017-04-04
    Description: The geochemical and isotopic composition of surface waters and groundwater in the Velenje Basin, Slovenia, was investigated seasonally to determine the relationship between major aquifers and surface waters, water–rock reactions, relative ages of groundwater, and biogeochemical processes. Groundwater in the Triassic aquifer is dominated by HCO3 –, Ca2+, Mg2+ and δ13CDIC indicating degradation of soil organic matter and dissolution of carbonate minerals, similar to surface waters. In addition, groundwater in the Triassic aquifer has δ18O and δD values that plot near surface waters on the local and global meteoric water lines, and detectable tritium, likely reflecting recent (〈50 years) recharge. In contrast, groundwater in the Pliocene aquifers is enriched in Mg2+, Na+ , Ca2+, K+, and Si, and has high alkalinity and δ13CDIC values, with low SO4 2– and NO3 – concentrations. These waters have likely been influenced by sulfate reduction and microbial methanogenesis associated with coal seams and dissolution of feldspars and Mg-rich clay minerals. Pliocene aquifer waters are also depleted in 18O and 2H, and have 3H concentrations near the detection limit, suggesting these waters are older, had a different recharge source, and have not mixed extensively with groundwater in the Triassic aquifer.

    CLEAN SEA project: the test in Lake Vättern (Sweden) (2016)
    Details
    Publication Date: 2017-04-04
    Description: The CLEAN SEA (Continuous Long-term Environmental and Asset iNtegrity monitoring at SEA) project has been realized by eni e&p and its subsidiary Eni Norge in cooperation with Tecnomare in 2012. The aim of the project is to use a commercially available AUV properly upgraded, installed and operated by SAAB AUV, for the execu- tion of environmental monitoring in offshore zone. We participated to the project performing the environmental characterization of site (Lake Vättern, Sweden) selected for the field test of Clean Sea project, and to providing support to processing the collected data by the payload installed. In detail, in the first phase of the project, we char- acterized the site of interest analyzing the clime, the morphology, and the principal chemical and physical water and environmental parameters on the basis of historical data (meteorology, hydrology, hydrodynamic, wind, ice cover and natural resources of the lake). In the second phase of the project, we processed the oceanographic and environmental data acquired in Lake Vättern during the AUV tests. The tests have been performed in two different areas in the East and West side of the lake. In detail Temperature, Salinity, Methane, Turbidity, Chlorophyll, Col- ored Dissolved Organic Matter, Polycyclic Aromatic Hydrocarbons, Oxygen, pH, Oxidation Reduction Potential, Refined Oil and Crude Oil have been acquired in 21 different tests with 4 different mission types, and successively processed and evaluated. The analysis highlights the spatial and temporal variability for each parameter, and allows the comparison with the available historical data.

    Annual Acoustic Presence of Fin Whale (Balaenoptera physalus) Offshore Eastern Sicily, Central Mediterranean Sea (2016)
    Public Library of Science
    Details
    Publication Date: 2017-04-04
    Description: In recent years, an increasing number of surveys have definitively confirmed the seasonal presence of fin whales (Balaenoptera physalus) in highly productive regions of the Mediterranean Sea. Despite this, very little is yet known about the routes that the species seasonally follows within the Mediterranean basin and, particularly, in the Ionian area. The present study assesses for the first time fin whale acoustic presence offshore Eastern Sicily (Ionian Sea), throughout the processing of about 10 months of continuous acoustic monitoring. The recording of fin whale vocalizations was made possible by the cabled deep-sea multidisciplinary observatory, “NEMO-SN1”, deployed 25 km off the Catania harbor at a depth of about 2,100 meters. NEMO-SN1 is an operational node of the European Multidisciplinary Seafloor and water-column Observatory (EMSO) Research Infrastructure. The observatory was equipped with a low-frequency hydrophone (bandwidth: 0.05 Hz–1 kHz, sampling rate: 2 kHz) which continuously acquired data from July 2012 to May 2013. About 7,200 hours of acoustic data were analyzed by means of spectrogram display. Calls with the typical structure and patterns associated to the Mediterranean fin whale population were identified and monitored in the area for the first time. Furthermore, a background noise analysis within the fin whale communication frequency band (17.9–22.5 Hz) was conducted to investigate possible detection-masking effects. The study confirms the hypothesis that fin whales are present in the Ionian Sea throughout all seasons, with peaks in call detection rate during spring and summer months. The analysis also demonstrates that calls were more frequently detected in low background noise conditions. Further analysis will be performed to understand whether observed levels of noise limit the acoustic detection of the fin whales vocalizations, or whether the animals vocalize less in the presence of high background noise.
