Results from atmosphere-ocean general circulation models (AOGCM's) for the IPCC 4th Assessment Report are used to investigate surface mass balance (SMB) future projections of the Greenland ice sheet (GrIS). The most efficient models for the GrIS climate modeling are chosen by comparison between the 1970-1999 outputs (averages and trends) from the 20C3M Experiment outputs, and the reanalyses (ECMWF, NCEP) as well as climatologies. The SMB is estimated from the summer temperature (from which is deduced the run-off) and annual snowfall from the well-adapted AOGCM's. It is validated with 1970-1999 results from the regional climate model MAR by interpolating the AOGCM's outputs on the MAR grid. However, large uncertainties remain in these SMB projections due to the simplified physic and coarse AOGCM's resolution. High resolution simulations made with the MAR model (which simulates explicitly the SMB by taking into account the surface feedbacks) forced at its boundaries by a GrIS well-adapted AOGCM could bring more precise brief replies.

We evaluate the climate and environmental variability of Northern Chilean Patagonia during the Last Millennia, using a multi-proxy analysis of a sediment core from Lago Esponja (45°09’S, 72°08’W). The lake is located in the region of Aysen del General Carlos Ibanez del Campo, in NW Patagonia. The study focuses on a multiproxy analysis of sedimentary records. The longest core (150 cm long) was collected in 2014 at 40 m depth. The sediment, which is composed of light brown organic-rich clayey silt, was analyzed for sedimentology (grain size, magnetic susceptibility organic matter and biogenic silica content), mineralogy (X-ray diffraction) and geochemistry (elemental and isotopic analyses of C and N, XRF core-scaner at 1 mm resolution). The radiocarbon ages, measured on 3 macro-remains, demonstrate that the core covers the last 6.700 years. The sedimentation rate ranges between 0.1 mm/yr in the lower section (100-150 cm) and 0.4 mm/yr in the upper meter. Visual descriptions and Scopix radiographies show that the sediment record is finely laminated except a massive decimetric coarser and darker layer corresponding to a tephra (estimated age 700AD±50). Magnetic susceptibility (confirmed by scopix radiographies) highlights the presence of 8 additional millimetric tephra layers. The biogenic silica content of the sediment is low (mean 5%). Diatom assemblage is dominated by benthic and acidophilous species, with high saprobic values. None marked changes were observed regarding the dynamic of the lake. The high organic matter content (mean 15%) and its high C/N ratio (12.7) throughout the core indicate inputs of allochtonous and terrestrial organic matter. Such parameters present high sediment variability also marked by changes in the chemical composition. The laminations reflect changes in the allochtonous sedimentary inputs, with high terrestrial inputs during wetter conditions in relation with the Westerlies. The sedimentary records of Lago Esponja will be compared with Eastern lacustrine record from the same latitude in order to confirm the climate-driven record. [less ▲]

The western tip of the Corinth Rift is considered as the most active within this major extensional structure, as evidenced by: seismicity, GPS kinematics, and INSAR data (Bernard et al., 2006). Within the frame of a multidisciplinary project dedicated to seismic hazards assessment for this region, two offshore surveys - high resolution seismic reflection and gravity coring - were conducted in this area. They were dedicated to the Late Quaternary sedimentary fill as the latter was expected to record both long term deformation (Beckers et al., 2015) and sedimentary “events” related to major earthquakes and/or tsunamis. Seismic reflection imaging displays the time and geographical distributions of large submarine landslides (MTDs) during the last 100 kyr. Based on a morpho-sedimentary map and the active fault pattern, up to 2 m-long cores were selected to detect and characterise the possible impact of historical events. The chronological control is based on AMS 14C dating and four detailed 210Pb and 137Cs profiles. Sedimentation (components, sources, transport and settling mechanisms) was analysed through textural, chemical, and mineralogical parameters. Turbidites could be clearly separated from the hemipelagic deposits. Our attempt to correlate identified sedimentary “events” with historical data greatly benefited from a recently elaborated catalog (Albini et al., 2014) with precisely re-located epicentral areas. Cable breaks were also taken into account. Attenuation models (Papazachos & Papaioannou’s, 1997) were used to discuss paleo-intensities vs. distance form epicentral areas. From the whole set of cores, the following results may be underlined: - the correlations between cores from the different sites are not complete, including for a few neighbouring sites belonging to the same morpho-sedimentary unit; we relate these discrepancies to the complex bottom morphology and/or to bottom currents responsible for local erosion; - for several well-documented earthquakes and tsunamis, we could not find a clearly recorded sedimentary impact; - non earthquake-triggered MTDs (as the 1963 event) produced specific layers identical to the major earthquakes impacts. At the difference, for a few cores from the deep axial floor, several sandy or silty turbidites permit to establish correlations: i) between coring sites, ii) with earthquakes which stroke two different areas, respectively east and west of the concerned part of the Gulf. Furthermore, the sedimentary events show a particular time distribution for the last 600 yr: - two intervals with short recurrences: a recent one ( 1900 AD-Present or 1750 AD-Present) and an older one ( 1550 AD-1700 AD or 1450 AD-1800 AD); these time distributions differ from each coring site; - a long “quiet” period (150 to 200 yr). From these results, we tentatively consider this sedimentary record as an indicator of a migration of seismogenic faulting activity. Ref.: Albini, P., et al., 2014. Techn. Rep. I.N.G.V. Roma.

Late blight of potato, caused by Phytophthora infestans was studied by using a resistant clone of potato on one side and a susceptible clone on the other side. A gene coding putatively for an alpha-galactosidase has been isolated by mRNA reverse transcription polymerase chain reaction differential display and was shown to be differentially expressed between the resistant and the susceptible clone. alpha-Galactosidases catalyse the hydrolysis of alpha-1,6 linked alpha-galactose residues from oligosaccharides and it could be shown in the present work that raffinose content decreases at 30 h after infection by P. infestans in the resistant clone.
