“…Among studies that dealt with the distribution of major and trace elements from a chronological point of view, it is important to mention the ASCOP Project [3], the PRISMA Project [4,5], the work of Donelec and colleageues [13,14] and finally the PITAGEM Project [9].…”

“…The Adriatic Scientific Cooperation Program (ASCOP) Project [3] is the oldest of all the considered projects; lasting from 1977 to 1990, it was a multidisciplinary research project carried out within the framework of the Italian-Yugoslavian Multidisciplinary Program for the Protection of the Adriatic Sea and Coastal Regions from Pollution. In the context of this multidisciplinary project, several parameters (Supplementary Table S1a -online only) were investigated in the superficial sediments of the central and southern Adriatic Sea (Figure 1…”

“…The project analysed major and trace elements and, as ancillary data, the calcite and dolomite content, the percentage of sand, silt and clay, and the polycyclic aromatic hydrocarbon (PAH), polychlorinated biphenyl (PCB), dichlorodiphenyltrichloroethane (DDT) and organic matter content (Supplementary Table S1a -online only) of superficial sediments along the transepts Pescara-Sibenik and Vieste-Split (Figure 1(b)). In this project, De Lazzari et al [3] processed the data using a mathematical-statistical calculation of principal components (factors) which established relationships among the components. Areal distribution of the statistical factors showed that the fine grain-size fraction, with oxides and hydroxides, is the main means of sediment transport and the principal link between chemical, physical and granulometric elements in the Adriatic Sea, adsorbing most of the metals considered and some organic contaminants.…”

“…Typically correlation between factors and properties (PCs loadings), and numerical values of factors for samples (PCs scores) are used to explain actual meaning of PCs. After analysis, rotation is applied in order to optimize factor loadings (De Lazzari et al, 2004;Liu et al, 2003;Reiman et al, 2002;Smoleñski et al, 2002;Persson and Wedborg, 2001;Podani, 2000;Brown, 1998;Shine et al, 1995;Szefer et al, 1995;Meglen, 1992, to name just a few).…”

Abstract. Factors conditioning formation and properties of suspended matter resting on the sea floor (Fluffy Layer Suspended Matter -FLSM) in the Odra river mouth -Arkona Deep system (southern Baltic Sea) were investigated.Thirty FLSM samples were collected from four sampling stations, during nine cruises, in the period 1996-1998. Twenty six chemical properties of the fluffy material were measured (organic matter-total, humic substances, a variety of fatty acids fractions, P, N, δ13C, δ15N; Li; heavy metalsCo, Cd, Pb, Ni, Zn, Fe, Al, Mn, Cu, Cr). The so obtained data set was subjected to statistical evaluation.Comparison of mean values of the measured properties led to conclusion that both seasonal and spatial differences of the fluffy material collected at the stations occured. Application of Principal Component Analysis, and Cluster Analysis, to the data set amended with environmental characteristics (depth, salinity, chlorophyll a, distance from the river mouth), led to quantification of factors conditioning the FLSM formation. The five most important factors were: contribution of the lithogenic component (responsible for 25% of the data set variability), time dependent factors (including primary productivity, mass exchange with fine sediment fraction, atmospheric deposition, contribution of material originating from abrasion-altogether 21%), contribution of fresh autochtonous organic matter (9%), influence of microbial activity (8%), seasonality (8%).

“…These results corroborate the marine origin of these sediments as revealed by the binocular microscope observations mainly due to the existence of shell debris and confirmed by the grain-size distributions. Therefore, we suggested that the first component agreed with the fine fraction of the sediment, which is mainly composed of various types of clay minerals, usually abundant in surface sediments (De Lazzari et al, 2004). On the other hand, factor 2 ( Fig.…”

Abstract. Climate models project that rising atmospheric carbon dioxide concentrations will increase the frequency and the severity of some extreme weather events. The flood events represent a major risk for populations and infrastructures settled on coastal lowlands. Recent studies of lagoon sediments have enhanced our knowledge on extreme hydrological events such as palaeo-storms and on their relation with climate change over the last millennium. However, few studies have been undertaken to reconstruct past flood events from lagoon sediments. Here, the past flood activity was investigated using a multi-proxy approach combining sedimentological and geochemical analysis of surfaces sediments from a southeastern Tunisian catchment in order to trace the origin of sediment deposits in the El Bibane Lagoon. Three sediment sources were identified: marine, fluvial and aeolian. When applying this multi-proxy approach on core BL12-10, recovered from the El Bibane Lagoon, we can see that finer material, a high content of the clay and silt, and a high content of the elemental ratios (Fe / Ca and Ti / Ca) characterise the sedimentological signature of the palaeo-flood levels identified in the lagoonal sequence. For the last century, which is the period covered by the BL12-10 short core, three palaeo-flood events were identified. The age of these flood events have been determined by 210 Pb and 137 Cs chronology and give ages of AD 1995 ± 6, 1970 ± 9 and 1945 ± 9. These results show a good temporal correlation with historical flood events recorded in southern Tunisia in the last century (AD 1932(AD , 1969(AD , 1979(AD and 1995. Our finding suggests that reconstruction of the history of the hydrological extreme events during the upper Holocene is possible in this location through the use of the sedimentary archives.
