Abstract The so‐called ‘Tunguska Event’ refers to a major explosion that occurred on 30 June 1908 in the Tunguska region of Siberia, causing destruction over 2000 km 2 taiga, globally detected pressure and seismic waves, bright luminescence night skies Europe Central Asia, combined with other unusual phenomena. may be related impact Earth cosmic body exploded about 5–10 above ground, releasing atmosphere 10–15 Mton energy. Fragments impacting have never been found, its nature (comet or...
Abstract Cheko, a small lake located in Siberia close to the epicentre of 1908 Tunguska explosion, might fill crater left by impact fragment Cosmic Body. Sediment cores from lake’s bottom were studied support or reject this hypothesis. A 175‐cm long core, collected near center lake, consists an upper ∼1 m thick sequence lacustrine deposits overlaying coarser chaotic material. 210 Pb and 137 Cs indicate that transition lower occurred time Event. Pollen analysis reveals remains aquatic plants...
Abstract Sedimentological, geochemical and micropalaeontological data from sediment cores in the northwestern Adriatic Sea were obtained to reconstruct stratigraphic framework palaeogeographic setting during last post‐glacial sea‐level rise (14000–6000 yr BP). Four lithostratigraphic units identified: (a) distal plain deposits (>14000 BP), submerged first phases of marine ingression; (b) coastal lagoon system; (c) barrier‐lagoon system, which is dated back between 10019 ± 61 10228 174...
Total organic carbon (TOC) and total nitrogen (TN) concentrations fluxes were estimated in surface sediments of a shelf area the NW Adriatic Sea (Italy), together with lithology 210Pb contents at 18 stations during four cruises (1996–1998) carried out offshore Po River delta. Mass accumulation rates (MAR) ∼0.1–0.8 g cm−2 yr−1 TOC TN within range 0.5–1.4 0.08–0.19% dry weight, respectively. Their spatial variability showed direct correlation inputs suspended matter from River. A simplified...
The sediment composition of the coastal Lake San Puoto (Central Italy) was studied to obtain information on its recent environmental evolution (last 200 years). explorative fieldwork performed within framework EU-funded PALICLAS Project. Sediment and mass accumulation rates, calculated from 210Pb analysis, show mean values 0.27 cm y-1 0.11 g cm-2 respectively, with increasing 10 top (i.e. ca 1960 AD present). sedimentation is characterized by interplay three main components: detrital (either...
Land-ocean coupling was investigated for the Adige River-Adriatic Shelf system by analyzing precipitation, water discharge and suspended load records over period 1922-2000 comparing them with 210 Pbex porosity depth profiles of 4 marine cores taken along riverborne sediment transport pathway on shelf. The results show that precipitation affected only minor variations in yearly seasonal amounts but accompanied a significant decrease (increase) number wet days (precipitation intensity). River...
The first sediment core analyses were carried out in 1958, but it is only from 1985 onward that a modern palaeolimnological approach was applied to the study of Lake Orta, large and deep lake North Italy, heavily polluted by ammonia copper for about 50 30 years, respectively. Thus, we summarise those studies variety cores, collected different years sites, using both published unpublished data. Changes algal pigments (mainly chlorophyll derivatives, total single carotenoids), inorganic...
We describe the process of development a citizen science platform on Ocean Literacy designed and implemented during lockdown period 2020. As restrictions due to COVID-19 health emergency did not allow researchers organise public events field data collection activities related Literacy, we decided take advantage this situation by building an online bring issues directly into citizens' homes. The massive use digital tools all civic communities time has allowed us implement idea make it...
Water issues represent an increasing societal challenge, since the 70% of Planet Earth is covered by water. The intensive use hydrosphere changing structure and functions aquatic ecosystems their ability to produce goods services that are useful humans. It therefore necessary scientific community makes citizens aware results research on these informs them about need intensify study mechanisms underlie ongoing changes in ecosystems. To help meet this need, within 23rd Congress Italian...
Twenty eight short sediment cores, collected along six transects in two areas influenced by the frontal system formed Po River, were analysed for Th and Cs order to improve our knowledge on time scale deposition, accumulation mixing. Sedimentological mineralogical parameters also analysed._ The decreasing activities C/N values surface sediments indicate a input of terrestrial material during study period. Furthermore, low excess thorium inventories at some sites, together with sedimentary...
