Core Ideas OZCAR is a network of sites studying the critical zone. covers various disciplines. will help disciplines to work together for better representation and modeling The French zone initiative, called (Observatoires de la Zone Critique–Application et Recherche or Critical Observatories–Application Research) National Research Infrastructure (RI). OZCAR‐RI instrumented sites, bringing 21 pre‐existing research observatories monitoring different compartments situated between “the rock...
Dendritic valleys on the plateau and canyons of Valles Marineris region were identified from Thermal Emission Imaging System (THEMIS) images taken by Mars Odyssey. The geomorphic characteristics these valleys, especially their high degree branching, favor formation atmospheric precipitation. presence inner channels maturity branched networks indicate sustained fluid flows over geologically long periods time. These fluvial landforms occur within Late Hesperian units (about 2.9 to 3.4 billion...
Abstract The increasing availability of aerial photography and satellite imagery offers new possibilities for characterizing river morphology. precision very high resolution (VHR) images allows smaller scale objects within corridors to be studied. High survey frequencies provide increased opportunities the monitoring restoration. Following this evolution in platform technology, a small radio‐controlled motorized vehicle flying at low altitude was used study both channel water depth gravel...
3D stratigraphic geometries of the intracratonic Meso-Cenozoic Paris Basin were obtained by sequence correlations around 1 100 wells (well-logs). The basin records major tectonic events western part Eurasian Plate, i.e. opening and closure Tethys Atlantic. From earlier Triassic to Late Jurassic, was a broad subsiding area in an extensional framework, with larger size than present-day basin. During Aalenian time, subsidence pattern changes drastically (early stage central Atlantic opening)....
The European Space Agency (ESA) and Roscosmos ExoMars mission will launch the "Rosalind Franklin" rover in 2022 for a landing on Mars 2023.The goals of are to search signs past present life Mars, investigate water/geochemical environment as function depth shallow subsurface, characterize surface environment. To meet these scientific objectives while minimizing risk landing, 5-year-long site selection process was conducted by ESA, during which eight candidate sites were down selected one:...

Two displacement maps of the “La Clapière” landslide (France) have been derived over two periods 4 years (1995–1999 and 1999–2003) by correlation aerial photographs a QuickBird satellite image. The movement ranges from 2.5 m to 20 per year. Those values validated 13 points monitored conventional tacheometric measurements. Three areas with significant differences in velocity field mapped. Limits those are good agreement situ observations. Velocity show low long term temporal variability its...
The active Séchilienne landslide (Isère, France) has been continuously monitored by tacheometry, radar and extensometry devices for 25 years. Indeed, if the 3 mil. m3 of rocks in zone named ―Ruines‖ fell down, debris would dam Romanche valley. breaking overtopping rapid erosion bring a catastrophic flood other dramatic consequences throughout Given rockfall hazard most zone, it is impossible to use targets this area: Only reflectorless remote sensing techniques can provide information. A...
Defrosting processes observed on Mars are among the most unusual features described high‐resolution images. A defrosting sequence has been near crest of megadune located in Russell crater new images obtained from HiRISE instrument and hyperspectral cubes CRISM instrument, both board MRO. Hyperspectral show that frost overlaps entire middle winter. This is composed mainly CO 2 a small amount water ice. The deepest ice signatures megadune. monitored by reveals spatial heterogeneity refrosting...
Valley networks on Mars are the most obvious features attesting that different geologic processes and possibly climatic conditions existed in past. THEMIS images reveal valley within Melas Chasma, Valles Marineris, a Hesperian‐age canyon system. The Chasma dense highly organized, heads of valleys scattered at elevations. All these suggest were fed by precipitation. morphological details inner channels some floors, water flowed valleys. On DEM, flow into completely enclosed depression. edge...
