Glaciers in a warming world: Lessons from Holocene records based on the novel cosmogenic nuclide dating tool “in situ carbon-14” – WarHol
The current near-global retreat of mountain glaciers is among the most visible and worrisome evidence of the warming earth. What is the significance of this rapid ice retreat today and within a longer time perspective? Glaciers sensitively react to small climate variations, in particular temperature
Emergent properties of soil microbial functions: Upscaling from 3D modeling and spatial descriptors of pore scale heterogeneity – Soilµ-3D
Many models exist that describe the emission of greenhouse gases such as CO2 and N2O from soils. However, these global models need improvements to yield more accurate predictions. Indeed these models are ignoring important microscopic aspects of soils, in particular their high level of heterogeneity
Towards a Regional Ocean/ Ice Sheet / Atmosphere modeling System – TROIS-AS
The TROIS-AS project is designed to build a regional modeling system enabling the representation of physical mechanisms and feedbacks at the ocean/ice-sheet and atmosphere/ice-sheet interfaces. The scientific aim is to quantify the contribution of a key region of Antarctica to global sea level rise
Antarctic Precipitation : Remote Sensing from Surface and Space – APRES3
There is no precipitation measurement network in Antarctica to evaluate the performances of climate models for this parameter. Yet all models predict an increase of precipitation. This is the single most important positive term of the ice sheet mass balance, and an increase of precipitation will mod
INvestigation of tHe Atmosphere as a reaL Ecosystem – INHALE
INHALE proposes a novel multidisciplinary approach combining expertise in microbiology, biomolecular microbiology, atmospheric chemistry and physics to characterize atmospheric microbial life on a global scale and how it relates to biogeochemical cycling. Specifically, we will demonstrate how the ph
Variscan pegmatites as new potential mineral resources – VARPEG
The supply of raw materials to European countries is becoming under increasing pressure. France makes no exception to this situation which stimulates national initiatives in the field of mineral exploration. New types of granite-related mineralizations, such as granitic pegmatites, are being conside
Atmospheric circulation and Arctic hydrological cycle changes – AC-AHC2
During the past decades, the Arctic has warmed twice as fast as the global average, and Arctic land precipitation has increased. In addition to this polar amplification, recent changes in atmospheric circulation have contributed to accelerate Greenland ice sheet melt and Arctic sea ice loss. State-o
AErosol RadiatiOn and CLOuds in Southern Africa – AEROCLO-SA
The representation of clouds, aerosols and cloud-aerosol-radiation interaction remain one of the largest uncertainties in climate change, limiting our ability to accurately reconstruct and predict future climate change. The South East (SE) Atlantic is a region where high atmospheric aerosol loadings
Modelling and simulation of solid transport in rivers – SEDIFLO
The aim of the SEDIFLO project is to propose a new mathematical modeling of physical processes inducing erosion and sedimentation of particles in watercourses, by contributing to the transfer of recent mechanical knowledge towards hydraulic engineering. We seek in particular to model mechanical proc
SEDIments in the largest rivers of China: Messengers from geological processes and environmental chANges – SEDIMAN
The Anthropocene is the current geological period, during which mankind has become an agent of drastic modifications of the Earth’s environment. The effect of human activities are particularly visible in the so-called “Critical Zone” of the Earth surface, which is the thin veneer between rocks and t
The two giant rivers of China, trends in water resources due to climate change and human pressure – CHINA-TREND-STREAM
The overall objective of the “China-Trend-Stream” project is to quantify and understand the processes that have caused the observed historic trends in the Yangtze and Yellow River discharges and to project future trends until 2050. To do this, we propose a 3-year project based on a novel and ambitio
Combination of geophysical, hydrological and geochemical investigations to better understand and model past, present and future watershed functioning. – HYDROCRIZSTO
This project aims to evaluate water and soil resources evolutions related to climatic changes and anthropogenic actions (forest management) in Strengbach watershed (Vosges Massif/France – monitored since 1986). The scientific objectives are to improve our knowledge of this ecosystem in order to mo
ECOLOGICAL AND BIOGEOCHEMICAL IMPLICATIONS OF GLYCOSIDASES BOUND TO MARINE VIRUSES – CALYpSO
The main objective of CALYpSO is to explore the implication of polysaccharide depolymerase associated to marine viruses for ocean ecology and biogeochemistry. To address this question, we will develop an integrative strategy, from genes to ecosystems, to test the hypothesis that virus-bound polysacc
TRACE METAL LEGACY on MOUNTAIN AQUATIC ECOGEOCHEMISTRY – TRAM
As a response to the 2015 ANR panel?s call for a better understanding of the critical zone, ecosystems (both Axe 1), ecotoxicology (Axe 2) , TRAM is in our opinion a promising interdisciplinary and integrative project to face the different following challenges: 1) TRAM will assess changes in the int
Submarine Groundwater Discharge : a hidden source of chemical compounds at the land-sea interface – MED-SGD
The flow of groundwater into the coastal sea constitutes a vector for many chemical elements that may impact the quality of the coastal environment and marine ecosystems. Additionally, groundwater contributions are not considered to date in oceanic budgets. Although submarine groundwater discharge (
