“…During the geotechnical campaign, three boreholes were investigated and, for the first time, depths larger than 3 m below the seafloor were explored in the basin. The verticals (A1, A2, and A3 in Figure 1b), were drilled up to depths of 8.5, 16.5, and 18.2 m below the seafloor respectively, by means of a drilling apparatus that was mounted on a platform previously fixed in place [42]. Undisturbed samples were taken from boreholes.…”

“…Undisturbed samples were taken from boreholes. Moreover, nearby these boreholes, three other samples (i.e., A1-M, A2-M, A3-M) were taken manually in the first meter of sediments by a team of expert scuba divers [42]. The 101 mm diameter samplers were made in polyvinylchloride (PVC), therefore characterized by high chemical and mechanical resistance.…”

“…The data presented in the paper refer to chemical and geotechnical properties of MP sediments. The chemical investigation was conducted throughout the basin [22,28,29] on samples collected up to 3 m bsf, and the more recent geotechnical investigation was carried out within the most polluted "170 ha area" [42]. In the following, the characterization of sediments taken from site A3 will be presented, being both the deepest one and the site investigated in more detail through chemical, mineralogical and geotechnical analyses.…”

“…In the following, the characterization of sediments taken from site A3 will be presented, being both the deepest one and the site investigated in more detail through chemical, mineralogical and geotechnical analyses. The geotechnical data from [42] were modified in order to consider the influence of pore fluid salinity and shell fragments on the soil properties (see Section 2.3). Moreover, new mechanical results on the deepest sample belonging to the ASP formation were presented in this paper, together with the results of the experimental procedure carried out on a portion of the shallow sample A3-M, in order to test the sediment sensitivity to some chemical changes.…”

The city of Taranto in the south of Italy is one of the areas declared as "at high risk of environmental crisis" by the Italian government because it represents one of the most complex industrial sites in Europe, located near urban areas of high population density. The rich ecosystem of the Mar Piccolo basin, located at north of Taranto, started exhibiting unconfutable signs of environmental pollution, confirmed by the high concentrations of organic and inorganic contaminants. Among the different aspects involved in the environmental studies aiming at the basin remediation, this paper focuses on submarine sediments and reports some results of the geotechnical laboratory investigations which made also use of non-standard equipment and revised procedures for data interpretation in order to take account of the sediments' contamination and heterogeneities. The geotechnical laboratory tests show that, despite the Mar Piccolo recent Holocene sediments having similar origin and composition to those of the Sub-Apennine clay basic formation, their behavioral facets appear to be altered by the presence of contaminants of both natural and anthropogenic origin. Results of washing tests are also presented as a first attempt to quantify the effects of chemo-mechanical coupling processes on the plasticity properties of the shallow sediments.Geosciences 2019, 9, 333 2 of 20 of chemo-mechanical coupling processes on the index properties of kaolinite, smectite, and mixed clay samples, observed after mixing the clay with solutions of different chemical compositions were discussed by several authors [3][4][5][6][7][8]. The potential of chemical-mechanical coupling is greatest in fine-grained soils at low confinement and such coupling may prompt highly variable effects for different clay fabric conditions [9]. In this context, the research on Mar Piccolo (MP) sediments aims to add an original contribution on the behavior of fine-grained sediments affected by a real pattern of contamination.The MP basin in the South of Italy represents a natural site characterized by the presence of contaminants of different sources and composition. The basin is located just behind the coast of the city of Taranto (Figure 1a), one of the most important industrial sites in Europe and represents, at the same time, an unusual ecosystem from a naturalistic point of view, with several animal and plant protected species and wide areas for mussel cultivation and fishing activity. Due to these peculiar conditions, the MP basin has been declared 'at high risk of environmental crisis' [10] and included in the list of the Sites of National Interest (SIN; [11]), to be subjected to comprehensive investigation for a preliminary selection of sustainable strategies for both its remediation and management. The paper shows the environmental boundary conditions of the MP and focuses on the results of geotechnical characterisation of marine sediments, that has been carried out to derive a geotechnical model of the area up to depths of engineering interest. The data of so...

“…The article by Vitone et al (2016) describes the mineralogy, composition, and physical properties of the sediments along three 20-m-long sediment cores, collected in the most contaminated area of the Mar Piccolo, to gain geotechnical information necessary to plan in situ mitigation solutions. The paper by Bellucci et al (2016) focuses on major and trace elements, PAHs, and PCBs determined in surface sediments and sediment traps collected in two periods with the aim to evaluate the contamination degree, sediment transport, and particle redistribution dynamics within the area.…”

The Project RITMARE (la Ricerca ITaliana per il MARE—Italian Research for the sea) is one of the national research programs funded by the Italian Ministry of University and Research. RITMARE (2012–2016), coordinated by the National Research Council (CNR), and has involved an integrated effort of most of the scientific community working on marine and maritime issues. Within the project, different marine study areas of strategic importance for the Mediterranean were identified: among these, the coastal area of Taranto (Ionian Sea, southern Italy) was chosen for the presence of large industrial settlements and their impact on the marine environment
