Reconstitution paléocéanographique du signal delta15N : modélisation couplée physique et biogéochimique d'un upwelling côtier

Afin de reconstruire le signal isotopique sedimentaire dans uncontexte d'upwelling cotier, nous avons developpe un modele couple physique et biogeochimique pouvant prendre en compte le fractionnement des isotopes de l'azote au sein d'un reseau trophique. Le modele biologique est un modele NPZD (Nutriments, Phytoplancton, Zooplancton, Detritus) qui prend en compte le fractionnement des isotopes de l'azote lors de l'assimilation des nutriments et lors de l'excretion du zooplancton. Le modele physique POM (Princeton Ocean Model) simule la circulation de l'upwelling cotier. Applique pour differentes situations de niveaux marins, ce modele couple nous permet de reproduire les signaux sedimentaires d15N et flux d'azote organique et d'en tirer des conclusions sur les scenarios paleoceanographiques. Au large du Cap Blanc, Mauritanie, l'effet de la montee du niveau marin, par l'immersion de la plate forme continentale, semble etre le principal facteur responsable lors de la derniere deglaciation des variations de flux d'azote organique et du signal isotopique au niveau des sediments. Ceci nous permet de proposer que le bilan d'azote oceanique au cours de la derniere deglaciation ait pu etre plus equilibre et stable qu'initialement prevu. Cet effet s'accompagne d'une periode de fonctionnement de l'upwelling qui aurait pu etre plus longue au Dernier Maximum Glaciaire, aux environs de 10 mois, contre 4-5 mois pour l'actuel. Ce modele a aussi ete applique au systeme du Benguela (Afrique du Sud Ouest) pour etudier certains processus de recyclage.
Compilation of the MOPEX 2004 results

As part of the MOPEX 2004 workshop, the participants were asked to submit simulations using the common database provided for the workshop (see Chahinian et al., this issue). The simulations were then analysed and the evaluation criteria computed to compare the models' performance for the gauged and ungauged modes using six criteria describing the model's performance in both high and low flow conditions. The comparisons were undertaken for all three participation levels (i.e. 3, 12 and, 40 catchments). The results indicate that on the 3-catchment level model ranking may vary according to the tested criterion and catchment. Hence a larger number of catchments are necessary to evaluate the models' performance. Among the 10 models tested on the 12 and 40 catchment samples in gauged mode, GR5H, Mordor and SAC-SMA rank as the top three models. When analysing model results in the ungauged mode, SAC-SMA ranks as the best of the four tested models. The analysis of the submitted files highlights the need for continuing efforts to develop model parameterization strategies for ungagued catchments in order to improve prediction in ungauged basins (PUB).
Fire severity and pine regeneration in the Eastern Iberian Peninsula.

We asked to what extent post-fire regeneration of Pinus halepensis (Aleppo pine) woodlands is related to fire severity. To answer this question we studied the regeneration of pine woodlands after a wildfire in Canabes, in the eastern Iberian Peninsula. We defined two fire severity classes based on the degree of consumption of the pine canopy: low (canopy retaining >20% of green leaves) and high (canopy with >80% of the leaves consumed). The results suggested that there is no clear relationship between seedling density and fire severity; however, seedling growth (shoot biomass and root biomass) was higher in the high severity class. Analysis of foliar nutrients suggested a tendency towards higher soil nutrient availability (especially P) during the first post-fire year in the high fire severity plots. Mortality of resprouting species was higher in the high severity class. We hypothesise that the results of higher growth in high fire severity plots can be explained by soil processes: Sites in the high fire severity class may have sustained higher fire intensities, which are related to higher soil organic matter mineralisation and, thus, to higher post-fire soil fertility. This higher fertility would produce higher survival and growth. The fact that plots with different canopy damage seem to show different soil nutrient dynamics and different resprouting failure suggests that fire severity at the canopy level may be related to fire intensity at the ground level.

What's your social media strategy?

A global bank executive recently described to us a challenge for our times. It turns out that a customer who normally would qualify for the lowest level of service has an impressive 100,000 followers on Twitter. The bank isn’t doing much yet with social media and has no formula for adapting it to particular customers, but the executive still wondered whether the customer’s “influence” might merit special treatment. It’s the kind of perplexing question many companies face as they formulate their thinking about social media. To understand how businesses are approaching the challenge, we analyzed strategies and practices at more than 1,100 companies across several industries and continents, and conducted in-depth interviews with 70 executives who were leading social media initiatives. Our research revealed four distinct social media strategies, which depend on a company’s tolerance for uncertain outcomes and the level of results sought. The “predictive practitioner. ” This approach confines usage to a specific area, such as customer service. It works well for businesses seeking to avoid uncertainty and to deliver results that can be measured with established tools. To increase Clorox’s virtual R&D capabilities, the social media team created Clorox Connects—a website that enables brainstorming with customers and suppliers. A typical query posted there: “We’re working on X product idea. What features would you like to see included? ” To encourage participation, Clorox uses incentives borrowed from gaming. For example, people who post answers or add rating comments are awarded points. The site features diff erent levels of diffi culty, and contributors who demonstrate expertise can advance to problems requiring greater creativity, knowledge, and involvement. The sharpest contributors gain visibility, making participation rewarding and sticky. One early success came after Clorox posted a question about a specifi c compound for its salad dressings. Five responses quickly came in. The company decided on a solution within a day and brought the problem solver into the product development process. The “creative experimenter. ” Companies taking this approach embrace uncertainty, using small-scale tests to fi nd ways to improve discrete functions and practices. They aim to learn by listening to customers and employees on platforms such as Twitter and Facebook. Sometimes they use proprietary technologies to conduct internal tests .

Étude des minéraux hydratés à la surface de Mars par les imageurs hyperspectraux OMEGA/MEx et CRISM/MRO

La planete Mars a connu une periode ou l'eau liquide etait durablement stable. Outre les vestiges morphologiques d'une activite hydrologique en surface, l'interaction chimique de l'eau avec la croute basaltique s'est traduite par la formation d'argiles et de sels hydrates en surface et en profondeur. Ces mineraux hydrates ont ete detectes a la surface de Mars en 2004 grâce a l'instrument OMEGA, l'imageur hyperspectral infrarouge proche embarque sur la sonde europeenne Mars Express. Leur etude permet de reconstruire l'histoire de l'activite aqueuse sur Mars et de caracteriser une periode ancienne ou l'environnement a pu etre favorable a l'apparition d'une chimie pre-biotique. Ce travail de these s'interesse aux environnements aqueux de Mars en couplant les donnees mineralogiques des imageurs hyperspectraux embarques OMEGA/Mars Express et CRISM/Mars Reconnaissance Orbiter avec la morphologie. De nouveaux outils de traitement et d'analyse des donnees sont developpes et ont permis la detection et la caracterisation spectrale de plus d'un millier de depots de mineraux hydrates sur Mars, fournissant une vue d'ensemble de l'alteration. Celle-ci a eu lieu principalement dans la premiere partie du Noachien et a surtout forme des phyllosilicates ferro-magnesiens de la famille des vermiculites et smectites. Une importante diversite minerale est par ailleurs constatee avec une dizaine de familles minerales differentes, tracants des conditions geo-chimiques variees. Places dans leur contexte geologique, certaines detections permettent de proposer l'existence passee d'un systeme hydrologique sur l'ensemble de la planete qui a donne naissance a un cycle des argiles similaire au cycle terrestre. Il apparait par ailleurs que les crateres d'impact sont le contexte privilegie des mineraux hydrates, mais le lien entre ces derniers et les processus d'impact demeure ambigu. La decouverte d'un cycle des argiles est compatible avec l'hypothese d'une planete potentiellement habitable au Noachien mais qui devra etre verifiee par l'exploration in-situ.

Associations between Extreme Precipitation and Gastrointestinal-Related Hospital Admissions in Chennai, India

Background: Understanding the potential links between extreme weather events and human health in India is important in the context of vulnerability and adaptation to climate change. Research exploring such linkages in India is sparse. Objectives: We evaluated the association between extreme precipitation and gastrointestinal (GI) illness-related hospital admissions in Chennai, India, from 2004 to 2007. Methods: Daily hospital admissions were extracted from two government hospitals in Chennai, India, and meteorological data were retrieved from the Chennai International Airport. We evaluated the association between extreme precipitation (≥ 90th percentile) and hospital admissions using generalized additive models. Both single-day and distributed lag models were explored over a 15-day period, controlling for apparent temperature, day of week, and long-term time trends. We used a stratified analysis to explore the association across age and season. Results: Extreme precipitation was consistently associated with GI-related hospital admissions. The cumulative summary of risk ratios estimated for a 15-day period corresponding to an extreme event (relative to no precipitation) was 1.60 (95% CI: 1.29, 1.98) among all ages, 2.72 (95% CI: 1.25, 5.92) among the young (≤ 5 years of age), and 1.62 (95% CI: 0.97, 2.70) among the old (≥ 65 years of age). The association was stronger during the pre-monsoon season (March–May), with a cumulative risk ratio of 6.50 (95% CI: 2.22, 19.04) for all ages combined compared with other seasons. Conclusions: Hospital admissions related to GI illness were positively associated with extreme precipitation in Chennai, India, with positive cumulative risk ratios for a 15-day period following an extreme event in all age groups. Projected changes in precipitation and extreme weather events suggest that climate change will have important implications for human health in India, where health disparities already exist.

Satellite Observations of the Sea Surface Salinity Response to Tropical Cyclones

Decade‐long satellite sea surface slinity (SSS) observations show that rain dilution prevails in wakes of tropical depressions (∼−0.1 pss) and tropical storms (∼−0.05 pss) on the left (right) side of Northern (Southern) Hemisphere storms. For stronger storms, the rain‐induced dilution is dominated by the saltier water entrainment, leading to surface median salinification of 0.3 pss for the most intense storms, peaking on the right‐hand side at around twice the maximum wind radius. The magnitude of the salty wake increases for stronger slowly moving storms. The vertical salinity gradient in the upper ocean is a key factor explaining the geographic distribution of the SSS response. A striking example is the systematic mixing of fresh near‐surface river plume waters with saltier subsurface waters. It is also found that barrier layers lead to saltier and warmer storm wakes compared to wakes produced over barrier layer free areas.
STABILITY OF TRANSITION FRONT SOLUTIONS IN CAHN-HILLIARD SYSTEMS (Mathematical Analysis in Fluid and Gas Dynamics)

We consider the asymptotic stability of transition front solutions for Cahn–Hilliard systems on R. Such equations arise naturally in the study of phase separation, and systems describe cases in which three or more phases are possible. When a Cahn–Hilliard system is linearized about a transition front solution, the linearized operator has an eigenvalue at 0 (due to shift invariance), which is not separated from essential spectrum. In many cases it is possible to show that the only non-negative eigenvalue is λ = 0, and so stability depends entirely on the nature of this neutral eigenvalue. In such cases, we identify a stability condition based on an appropriate Evans function, and we verify this condition under strong structural conditions on our equations. Due to lack of a spectral gap, nonlinear stability cannot be concluded from classical semigroup considerations and a more refined development is appropriate. One of our main results asserts that spectral stability implies nonlinear stability.
Modeling nitrous oxide emissions from agricultural soil incubation experiments using CoupModel

Abstract. Efforts to develop effective climate mitigation strategies for agriculture require methods to estimate nitrous oxide (N2O) emissions from soil. Process-based biogeochemical models have been often used for field- and large-scale estimates, while the sensitivity and uncertainty of model applications to incubation experiments are less investigated. In this study, a process-oriented model (CoupModel) was used to simulate N2O and CO2 fluxes and soil mineral nitrogen (N) contents in a short-term (43 d) factorial incubation experiment (16 treatments). A global sensitivity analysis (GSA) approach, “Morris screening”, was applied to quantify parameter sensitivity. The GSA suggested that a higher number of sensitive parameters was associated with N2O flux estimates and that inter-treatment variations in parameter sensitivities were distinguished by soil moisture levels or NO3- content and residue types. Important parameters regarding N2O flux estimates were linked to the decomposability of soil organic matter (e.g., organic C pool sizes) and the denitrification process (e.g., Michaelis constant and denitrifier respiratory rates). After calibration, the model better captured temporal variations and magnitude of gas fluxes and mineral N in unamended soils than in residue-amended soils. Low-magnitude daily and cumulative N2O fluxes were well simulated with mean errors (MEs) close to zero, but the model tended to underestimate N2O fluxes, as observed daily values increased by over 0.1 g N m−2 d−1, in which the major mismatch was due to limited success of the model to describe the high emissions during the first few days after crop residue addition. A larger uncertainty was also seen in the magnitude of pulse emissions by the posterior simulations. We also evaluated ancillary variables regarding N cycling, which indicated that more frequent measurements and additional types of observed data such as soil oxygen content and the microbial sources of emitted N2O are required to further evaluate model performance and biases. The major challenges for calibration were associated with high sensitivities of denitrification parameters to initial soil abiotic conditions and the instantaneous residue amendment. Model structure uncertainties and improved modeling practices in the context of incubation experiments were discussed.

Extreme Precipitation during 1921 in the Area of the Niwot Ridge Long-Term Ecological Research Site, Front Range, Colorado, U.S.A.

An unusually high amount of precipitation, including a world record 24-h snowfall, was recorded in 1921 at Silver Lake, Colorado, near the Niwot Ridge alpine tundra Long-Term Ecological Research (LTER) site. There was 68.3 in (1735 mm) total annual precipitation which was over five standard deviations above the 1914-1992 mean and the April snowfall produced 76 in (1.93 m) of snow in 24 h. An investigation of these phenomena brings to light the following points. The precipitation at Silver Lake, and presumably the Niwot Ridge LTER site, during 1921 was exceptionally high. The precipitation was highly localized. There are no obvious causes for the high precipitation to be found in the synoptic climatology for the year. However, moisture sources from the west in the winter and spring and from the south in the summer do seem to have been available. Despite well-marked, but temporary, impacts on humans and possibly other higher mammals, there is no evidence of any major or long-lasting impacts to the alpine tundra or subalpine forest ecosystems. Higher temperatures and persistent drought, as might be found with global climatic warming, are proposed as potentially more important disturbance factors to these systems.
