. High-resolution acoustic mapping of gas charged sediments and living benthic foraminifera assemblages from the NE region of the Guanabara Bay (RJ, Brazil). Journal of Sedimentary Environments, 1 (3): 360-384. AbstractThis work was performed in the NE region of the Guanabara Bay, a highly impacted Brazilian coastal system, located in Rio de Janeiro State. It aimed to: i) identify and map the areas with occurrence of gas in the sediment, as well as its acoustic signature; ii) characterize the physical properties of the sediments and; iii) document the response of microbenthic organisms (living benthic foraminifera) to changes in quantity and quality of organic matter. Seismic surveys at the frequency of 12 kHz identified a large area with about 50% gas charged sediments in the study area.The main acoustic signatures of the shallow gas were black shadow and gas blanket. In addition, features related to gas seepages to the water column (acoustic plumes and pockmarks) and gas percolation within the sediments (intrasedimentary plumes, turbidity pinnacles) were also identified. The gas has a biogenic origin and results from the high acumulation rate between 0.03 to 0.9 cm.year -1 and from the decomposition of large amount of organic matter (10-20%). Vertical distribution of gas ranges from few centimeters to 9 m below the water-sediments interface. These occurrences are related to both gas migration from lower sedimentary layers to Holocene muds above, and to recent generation in near-surface sediments as the area display favorable conditions for gas production. Cores ranging from 150-240 cm in length have predominantly muddy sediments and variations in the P-wave velocity followed the changes in sediment density, controlled mainly by the presence of gas in sediments, bioclasts accumulation, textural variation and percentage of organic matter.

“…These works evidenced that Ammonia tepida was the most abundant species in samples at the sediment-water interface. The A. tepida -Elphidium excavatum foraminiferal assemblage represented an environment under stress (Vilela et al, 2011). At the Guanabara Bay, foraminiferal results at sedimentwater interface presented A. tepida, Buliminella elegantissima and Quinqueloculina seminulum as dominant species at different regions.…”

“…About 1.3 tons of fuel oil escaped into the bay water in the northern region and spreaded by near 2/3 of the total sea-water extension and sediment-water interface, with high consequences for the life in all trophic levels and for Foraminifera are largely studied to interpret environment characteristics, like salinity, pH, organic matter, anoxic events, and changes by human impacts (Boltovskoy et al, 1980;Culver & Buzas, 1995;Geslin et al, 2002;Murray, 2006). Foraminiferal tests are commonly abundant in the sediments and they are easily collected in distinct Brazilian estuaries, bays and lagoons (Vilela et al, 2003(Vilela et al, , 2011Barbosa et al, 2005;Eichler et al, 2006;Machado & Araujo, 2014). Foraminiferal studies in the central and northeast regions of the Guanabara Bay pointed out the occurrence of bioindicator species and similarity between dead and living assemblages (Eichler et al, 2014;Martins et al, 2016aMartins et al, , 2016b.…”

In January 2000, Guanabara Bay in Rio de Janeiro experienced a major oil spilling caused by a break down in one PETROBRAS oil pipeline. Over than 1.3 tons of fuel oil escaped into the bay water in the northern region. Studies of foraminiferal taphonomic assemblages in sediment samples collected on three periods in the same stations, before and after the spilling, were important for the pollution impact evaluation during eight years.

Combined natural processes and human activities shaped the late Holocene landscape history in many Mediterranean regions. This is especially true with areas subjected to specific human interest, such as coastal areas morphologically suitable to the establishment of harbours. Here, we test the hypothesis on the location of the Roman harbour Portus Trajectus in Peloro Cape (NE Sicily, Italy) and describe the evolution of the area over the last 3700 years through lithostratigraphic, geochemical, meiofauna and microfossil analyses performed on a new sediment core recovered from the coastal salt marsh Pantano Grande (aka Lago di Ganzirri). The age–depth model was developed on radiocarbon dates and geochemical fingerprinting of two tephra layers. Results indicate that the area underwent dramatic changes ca. 650 bce. The anthropogenic impact of Greek colonies may have contributed to modifying the coastal environment of Peloro Cape due to their widespread impact on natural resources. This happened at many localities in the Mediterranean, indicating the magnitude of impact of the Greek colonies over the landscape. According to our results, it is unlikely that the current Pantano Grande basin was used as a harbour in Roman times, although the presence of a harbour in the nearby Pantano Piccolo marsh cannot be excluded. Pantano Grande had been isolated from the sea for more than 2000 years. Human intervention in the 19th century halted that isolation and provided the background for the ecological, economic and social functions the salt marsh performs today.
