“…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].…”

“…It had several objectives including setting up new oceanographic instruments, a new coastal marine-monitoring integrated network in the Gulf of Manfredonia, in the Gulf of Taranto and along the coasts of Sicily, the realisation of a marine coastal satellite data elaboration method and database to estimate biological and physical parameters and, finally, a multidisciplinary study of the trophic and biogeochemical processes in the water column of the Gulf of Manfredonia and their relationships with the bottom sediments [8]. The last objective involved studying biogeochemical and sedimentological characteristics (Supplementary Table S1a -online only) of the Gulf of Manfredonia (Figure 1 Table S1a -online only) of the Gulf of Manfredonia and the central and southern Adriatic Sea (Figure 1(c)) [9][10][11].…”

“…In the Adriatic Sea, the Manfredonia Gulf is characterised by relatively high concentrations of trace elements such as Cr and Ni. This geochemical accumulation of trace elements denotes fine sediment enrichment (Spagnoli et al, 2008).…”

Over several decades, the mouth of the Mejerda River (northern Tunisia) has received large amounts of mining tailings mainly containing Pb, Zn and Ba. We have measured the concentrations of major and trace elements (Al, Ti, P, K, Mg, Na, Ca, S, Fe, Cl, V, Cr, Co, Ni, Cu, Zn, Ga, Br, Rb, Sr, Y, Zr, Nb, I, Ba and Pb) in three different fractions of 45 surficial sediments using wavelength dispersive X-ray fluorescence. The size distribution of fine particles (<2 µm, 2-20 µm, 20-63 µm) revealed that clay and silt compounds were predominant (75-95%) in the deeper estuarine region. These condensed clay phases were mainly dioctahedral smectite, illite and kaolinite. The total organic carbon (TOC) concentration varies from 0.08 to 1.37 %. The C:N ratio varies from 1 to 17 indicating that the organic matter has a mixed marine and continental origin principal component analysis was used to determine the associations of trace elements with organic and/or inorganic phases of the sediment fractions. The correlations of Fe 2 O 3 , MnO 2 and P 2 O 5 with trace elements showed that amorphous Fe and Mn were the most active scavengers of dissolved metals from the Mejerda River. Cluster analysis clearly distinguished local trace element accumulations according to grain size fractions (< 2 µm and 2-20 µm) near the Ghar el Melh Lagoon and the Mejerda River.

“…Factor 1 accounts for 64.46 % of total variance. It is characterised by high positive loadings for Fe, Ti, K, and Al, which indicates the dominance of alumino-silicates minerals in surface sediments (Spagnoli et al, 2008;Plewa et al, 2012). These elements are prevailing in the river surface samples and their granulometric distributions shows that their grain sizes are in the range of clay and silt.…”

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.
