Lessons from our ancient Frozen Planet: towards an unified theory for glacial sequence stratigraphy – SeqStrat-Ice
Glaciations, characterized by the development of vast continental-scale ice sheets, occurred repeatedly during the course of Earth history. A profound understanding of the circumstances that led to the emergence and subsequent demise of these ice sheets remains one of the main challenges in palaeocl
Secondary Aerosol Formation in the MEDiterranean – SAF-MED
The formation of high organic concentrations observed in summer in the western Mediterranean may be explained by different processes: * Organic marine emissions * Biogenic VOCs interact with anthropogenic plumes and marine emissions * Formation of SOA (secondary organic aerosols) du
Dynamics of an arc volcano with extruding lava domes, Merapi (Indonesia): from the magma reservoir to eruptive processes – DOMERAPI
DOMERAPI proposes a unique and robust multidisciplinary research approach to attack the fundamental issue of understanding causal links between monitoring and phenomenological observables of volcanic unrest and transitions in eruptive styles with the dynamics of the physico-chemical processes of the
Role of continental configuration in the development of worldwide ANOXia in bottom ocean SEAwater. – Anox-Sea
This project relies on three main aims : 1) to identify the changes in oceanic circulation during the Late Cretaceous and their links to the oxygenation state of the oceans and to the paleogeography; 2) to constrain the evolution of continental weathering during the Late Cretaceous; 3) to identify t
Emulation techniques for the REduction, Sensitivity Analysis and INversion of models for subsurface hydrology – RESAIN
This project handles subsurface flow and reactive transport problems by addressing the four following methodological topics: (i) model uncertainty analysis, (ii) model sensitivity analysis, (iii) model reduction in the case of computationally expensive simulators and, (iv) inverse modeling. Two type
Tropospheric Observing System for the Investigation and Management of the Environment – VOLTIGE
Over the past decade, the scientific community has embraced the use of autonomous RPAS (remotely piloted aircraft system) as tools to improve observations of the Earth’s surface and atmospheric phenomena. Their use in atmospheric research has increased because of their relative low-cost, compact siz
Mercury Biogeochemistry: Relations between speciation, bioaccumulation and ecotoxicity – MERCURIUS
Bioaccumulation of Hg from the bottom to the top of the food chain is a worldwide concern for ecosystem health and human food supply. Associations of Hg with natural organic matter (NOM) to a great extent determine the bioavailability and toxicity of this hazardous element in the biosphere. There is
Survey and Modelling of East Antarctica – SUMER
- Better understanding of the specific dynamics of outlet coastal glaciers. - Enhanced study of the glaciological processes over the test zone - Extension of these results to the whole study area (WAL sector) for a better assessement of its future contribution to global sea level. - Good unde
Geometry of Strike-Slip faults through Multiple Earthquake Cycles – GeoSMEC
The focus of the project is to understand the interaction between strike-slip fault geometry and rupture propagation, from the scale of the laboratory to the scale of field observation still to come still to come NA The project “ Geometry of Strike-slip faults through Multiple Seismic Cycles ” aims
A new prototype of fast-heating oven dedicated to roc magnetism investigations – FUReMAG
This project focuses on the development of a new type of experimental furnace dedicated to the magnetic properties of rocks. This instrument fits primarily in the chain of data acquisition for the observation of the past behavior of the Earth magnetic field. Two key points determine its specificatio
CALcification HIStory of the pelagic environment over the last 300 years – CalHis
Coccolithophores and planktonic foraminifera produce more than 90% of pelagic carbonates, thus being major actors in the global carbon cycle. Calcification of these unicellular organisms is known to be influenced by carbonate ion concentration and calcite saturation state of seawater as well as by o
Active, passive and altimetric measurements for the interpretation of canopy fluorescence – CALSIF
Vegetation plays a fundamental role in the functioning of land surfaces. A better understanding of the interactions between vegetation and atmosphere that would allow predicting the response of vegetation to future climate change is mandatory to design mitigation strategies. In this framework, remot
Apatite (U-Th)/He thermochronology: understanding diffusion behavior using multidisciplinary approaches – HeDiff
Quantifying the thermal evolution of the continental crust is key to understanding processes like mountain building and sedimentary basin evolution. Thermochronometry constitutes a widely used tool for this purpose but the physical processes determining thermochronometric ages remain incompletely un
Megathrust earthquakes in Chile: The 2010 Maule Earthquake (Mw 8.8) and sismo-tectonic implications – MEGA-Chile
To move ahead on the understanding of the mechanics of megathrust earthquakes we propose to study the 2010 Mw8.8 Maule earthquake in every possible detail and to put it into the perspective of the geodynamics of the Andean margin. The Chilean subduction is one of the most active in the world, with 4
Air-Sea Interaction and Coupling with Submesoscale structures in the MEDiterranean – ASICS-MED
The north-western Mediterranean is prone to strong wind events (Mistral, Tramontane) which may, when interacting with the upper ocean dynamics, lead to dense water formation and convective vertical mixing. The goal of ASICS-MED has been to study in detail the processes of kilometric scale that contr
Isotope tracers of volatile depletion in the solar system – ISOVOL
Most planetary materials including meteorites and planets show evidence for volatile depletion relative to the solar composition. The objectives of this project are to develop new isotope tracers for the conditions and timing of volatile element depletion in the early solar system. During the first
Using Water Stable Isotopes to Assess past, present and future tropical precipitation change – ISOTROPIC
Projections of tropical precipitation strongly differ from one climate model to another, both in sign and in amplitude. How to assess which of the model projections are likely to be the most reliable? By identifying the models that are most reliable both in simulating the processes that control pres
Organic Nitrates Chemistry: sources, sinks and impact on the long-range transport of reactive nitrogen – ONCEM
The photooxidant pollution is responsible of the air quality degradation by producing photo-oxidants such as ozone, potentially irritants secondary oxidized compounds or through production of secondary organic particles. The development of such phenomena involves complex interactions between the sol
