The overall objective of our work was to improve the knowledge of the arctic marine environment. Using satellite remote sensing operating in the visible, near infrared and thermal infrared, we studied oceanic surface structures over the Barents and Kara seas, as well as in the southern part of the Barents sea. In situ measurements obtained from oceanographic campaigns allowed us to validate the algorithms we used for image processing and helped us in analyzing the images. We studied both biological and physical oceanic structures. Concerning primary production, we showed in which areas and when phytoplanktonic bloom start to develop. We also emphasized the areas where thermal and hydrological fronts appear, sea ice drift and its relationship to surface currents, as well as the transport of sediments and associated pollutants by rivers and their outflow distribution patterns into the sea. The final goal of our work was to outline which areas of the eurasiatic arctic seas are the most sensitive and exposed if a pollution should occur. We finally concluded that two areas were particularly vulnerable: the marginal sea ice zone in the northern Barents sea that supports large part of the phytoplanktonic ecosystem, source of the food chain. Due to the intensity and very short timing of the phytoplanktonic bloom in that area, a pollution could have serious consequences there. Important exchange of water masses and ice, potentially contaminated, occur in the southeastern part of the Barents sea, which constitute a large refuge for marine mammals and migratory birds. Concerns about oil and natural gas exploitation should lead future investigations to focus on monitoring of both areas

With the goal of reducing the amount of greenhouse gases in the atmosphere, policy makers encourage practices intended to sequester carbon in soils (reforestation, changes in farming practices). New methods are required to rapidly and accurately measure soil C at field- and landscape-scales. Near infrared spectroscopy (NIRS) is an analytical technology adapted to these specifications but remains experimental research in soil science.This thesis has focused on the first step of this analytical method: signal formation. The soils are very complex materials, in terms of chemical composition and physical structure. Hence, the spectroscopic signal is negatively impacted by light scattering. Consequently, the conditions of the Beer-Lambert are no longer fulfilled, and the chemometric models to predict the carbon content of soils are less accurate and robust. We develop an original optical method based on light polarization spectroscopy to measure the absorbance of highly scattering materials. By selecting photons being less scattered, we compute a new absorbance signal which is a good approximation of the Beer-Lambert absorbance.This method, called Polis, was experimentally validated on model materials in liquid and powdered form. Applied on soils to predict Total Organic Content, the model built with the PoLiS absorbance outperform the models built with the classical absorbance computed from the diffuse reflectance signal

ITAP Research Unit of IRSTEA and Pellenc SA company want to developa visible - near infrared spectroscopy measurement system in order to assess the quality of olives and monitor their ripeness. The measurement has to be non-destructive and performed on a single olive. The ripeness criteria selected are water and oil content. The main objective of this work is to optimize the measurement of these criteria, recorded by a portable spectrometer, by taking into account the constraints linked to the studied object and by overcoming the obstacles imposed by the technology used. In relation to the industrial objectives, three scientific questions were raised :SQ1 : How to get the reference values of the ripeness criteria from a single olive ?SQ2 : How to measure the spectrum of one olive ? Which optical configuration isbest suited for an olive ? Which volume of the olive is actually analyzed during thespectral measurement ? Does the spectrum contain information about the kernel ?SQ3 : How to calibrate the spectral measurement ? Are the prediction models robustregarding a variety not used for the calibration step ? How to include the kernel mass in the predicted values ?In order to answer those questions, experimental and comparative studies have been led. As the determination of water content is easily transposable to a single olive, only the measurement of oil content is studied (SQ1). Two existing methods nuclear magnetic resonance and hexane extraction have been characterized end evaluated when they are applied to the pulp of a single olive.The comparative study conducted on different optical configurations(SQ2) has high-lighted the impact of each configuration (transmission, diffuse reflectance with guidedpropagation of light through a sphere, diffuse reflectance with free propagation of light and interactance) on the spectral measurement. This study has also determined if all of these configurations are suitable for the whole olive measurements. Furthermore, the real volume analyzed during the spectral measurement has been investigated by studying the loss of transmitted light through the skin and the pulp.In order to answer SQ3, the present work provides optimized models for prediction ofwater content on the one hand and oil content on the other hand. The robustness study leads us to consider different methods (Model Update, Biais and Slope, DOP, wavelength selection) depending on the correction set used and therefore the finality of the future device. Concerning the introduction of kernel mass in predicted values, it has be done using various methods which are more or less destructive. The choice of one of these methods has been be determined by the technical possibilities of the device and the minimum expected accuracy of water and oil content predictions.Therefore, the results of this thesis provide some elements to guide the development of a portable spectrometer for measurements on individual olive fruits
