Abstract

International audience; VP/VSor Poison’s ratio classically permit imaging fluids in rocks but this strategy remains underused in near-surface applications, hence in hydrogeophysics. Yet, P-wave refraction tomography and surface-wave dispersioninversion can be combined to produce 2DVPandVSsections from a single acquisition set up. This approachrecently proved to be efficient in the study of various hydrosystems and in the imaging of the Critical Zone. Wenow suggest its time-lapse application in order to help the monitoring of water content in the vadose zone/aquifercontinuum. With both laboratory experiments and field data, we show how the temporal variations of P-wave traveltimes and surface-wave dispersion are strongly associated to the variations of water content observed locally, thusencouraging to exploit the full wealth of seismic signals in hydrogeophysics.

Abstract

International audience; Between 1925 and 1940, an IFAO/Louvre mission has excavated Medamud. A new project has reopened the study on site since 2011 and in 2015 has performed a ceramic and geophysical survey in order to increase our knowledge of the kom. The numerous firing wastes prove that Medamud was one of the biggest production centers in Upper Egypt. The geophysical survey has highlighted the principal remains discovered by Bisson de la Roque around the temple. Our study has been largely focused on the areas never excavated, and has proved the existence of a new artisanal district specialised on the ceramic production, a new surrounding wall and a canal/channel linking Medamud with the Nile.; Les fouilles de Médamoud se sont déroulées entre 1925 et 1940 par l’Ifao à la demande du musée du Louvre. La mission Ifao/Paris-Sorbonne/Labex Resmed de Médamoud a repris depuis 2011 les activités sur le terrain. Les résultats d’une campagne de prospection géophysique et céramologique effectuées en 2015 sont présentés ici afin d’étendre nos connaissances du site. La présence de nombreux déchets de coction assure que Médamoud était un des plus grands centres de production de céramiques en Haute Égypte. La prospection géophysique a signalé par ailleurs la présence des principaux vestiges découverts par Bisson de la Roque dans les abords du temple et a permis de comprendre un peu mieux les parties du kôm qui n’ont pas encore été fouillées. La présence d’un quartier artisanal, d’un nouveau mur de clôture et d’un canal reliant Médamoud au Nil paraît désormais assurée

Abstract

International audience; A wide variety of remote sensing and ground-based (proximal sensing) methods have been developed to describe soil physical properties and their lateral variations. Remote sensing enables the estimation of soil properties over large areas, but the information is often limited to the soil surface. Ground-based methods enable the derivation of soil properties for the whole soil column thickness, although these methods cannot be conducted over large areas. The aim of the present study is to contribute to the assessment of the efficacy of airborne thermal prospection over bare soils in soil mapping. This study focuses on a comparison between this technique, which can investigate over the whole soil column thickness after a sufficiently long transient heat exchange period, and pedological and electrical resistivity data that were recorded for three different depths of investigation. The study area is located in the Beauce region, where the soils (haplic Calcisol or calcaric Cambisol) consist of a loamy–clay layer that is 0.3 m–1.4 m thick and overlies Tertiary Beauce limestone. Thermal measurements were recorded by ARIES radiometer in December after six days of heat loss from the ground. The investigation depth could thus be considered to be larger than the thickness of the ploughed layer. Comparisons using statistical analyses between the thermal measurements, electrical resistivity, and pedological data demonstrated that: (i) the spatial organization of the thermal inertia map is similar to the spatial organization of the 0-m to 1.7-m resistivity map; and (ii) the thermal apparent inertia values are significantly different between the haplic Calcisols and the calcaric Cambisols and can thus be mapped with a high spatial resolution over large areas. The applicability of thermal prospecting in soil mapping opens up many possibilities considering the present advances in light-infrared radiometers. Beside agronomical concerns, this methodology will also facilitate progress in engineering applications, including the cross estimation of electrical and thermal properties.

Abstract

Article consultable sur [http://web.b.ebscohost.com.inshs.bib.cnrs.fr/ehost/detail/detail?vid=0&sid=4978745d-4866-47ef-84fe-c9bf232b3b92%40sessionmgr120&bdata=Jmxhbmc9ZnImc2l0ZT1laG9zdC1saXZl#AN=118170097&db=asn]; International audience; This article addresses the characterization of resistive archaeological targets and near surface structures by electromagnetic induction (EMI). It presents tests achieved with the DualEM-421S instrument (Dualem Inc., Milton, Canada) in order to be able to quantitatively compare these measurements to the standard technique of direct-current (d.c.) resistivity. The test was done over the Gallo-roman site of Vieil-Evreux in Normandy, France and one-dimensional (1D) and three-dimensional (3D) inversions were applied to the data set obtained. We have first investigated the signal-to-noise ratio of each of the six DualEM receiver coils both in a static mode and for a quad-pulled system. The dependence on the roll angle was also measured and it is shown that rotation of DualEM must be taken into account if the roll angle is more than ±10°. Absolute calibration and in-phase/quadrature (out of phase) component discrimination was checked by measuring the response of a small conductive and non-magnetic sphere. Several electromagnetic soundings by measuring the instrument response at different heights were done in order to check the quadrature (out-of-phase) response of the instrument. Inversions of these electromagnetic soundings were compared to d.c. vertical electric soundings (VESs) over four locations and found in accordance. Several maps using different coil configurations (HCP, VCP, PERP) and different heights were performed and inverted, both for a wide mesh (5 m) and for a finer one (0.5 m). The wide mesh allows a global and rapid description of the surface geology context (continuous d.c. measurements cannot deliver equivalent depth of investigation). The fine mesh conductivity maps clearly show the walls of a fanum (temple) as well as other structures and prove that the DualEM-421S is able to map correctly archaeological resistive targets. These maps and their interpretations were compared to previous results obtained by d.c. technique.

Abstract

International audience; Statute laws concerning preventative archaeology adopted in France in 2001 for threatened sites required development of evaluation techniques. The common methodology used during the past 10?years has been extensive excavation. This method delivers a direct record of the discovered archaeological features and of their distribution. However, the success of visual observation can be variable, depending on geological context and the feasibility of envisaging the entire archaeological settlement from the part that is observed. We report here a case study from an early Middle Age settlement located on a floodplain. It was partially excavated and the alluvial context makes the features difficult to recognize for archaeologists. We show how the geophysical survey complemented the archaeological survey and allowed the detection of previously unrecognized features. In a second step, we compare the results of surveys with magnetic and electromagnetic methods on a topsoil stripped area and the neighbouring surface. From this analysis we conclude that a significant part of the unrecognized features discovered were present above the level of stripping. This example underlines that the practice of topsoil stripping has to be reconsidered, and should be integrated with geophysical survey to limit the potential loss of archaeological information.

Abstract

The DIGISOIL project (FP7-ENV-2007-1 N°211523) is financed by the European Commission under the 7th Framework Programme for Research and Technological Development, Area “Environment”, Activity 6.3 “Environmental Technologies”. ; International audience; The clay (paramagnetic) and iron oxides (ferrimagnetic) contents carry the magnetic properties of soils. Changes in the local redox conditions influence the iron oxides fatum and, then, the magnetic properties of soils. Consequently, many processes (air circulation, microbial activities, heavy metal accumulation...) can influence the magnetic behaviour. The aim of this study is to evaluate which soil property(ies) (carbon content, bulk density, clay content...) can be mapped with the help of magnetic properties measurements (magnetic susceptibility, magnetic viscosity and there ratio). The survey has been achieved on the validation site defined in the DIGISOIL project and located in Luxembourg. This site is about 4 ha in area, it is cultivated and ploughed. We made 231 measurements with 5 devices (MS2D Bartington ltd, DECCO, TS6 Protovale, CS60 and VC100 prototype) in 7 configurations. 30 calibration cores were also collected to characterize soil properties (carbon content, clay content, stone content and water content) in the field. The results are used to analyse the relationship between soil and magnetic properties. When a relation appears, soil property maps derived from magnetic property ones are plotted and confronted with collected sample results.

Abstract

This deliverable D3.2 (Site preparation) is linked to the first task (3.1) of DIGISOIL’s WP3 (Implementation, field testing and validation on selected test sites). The objectives are here to report all the experiments that have been conducted on real test sites to evaluate the proposed methodology. Test sites are identified as Luxembourg (LU), Mugello (IT) and Zala (HU). For each geophysical method, the experimental conditions, data acquisitions, validation points and produced maps are presented. The optimal combination of petrophysical parameters are used to describe the aforementioned soil properties. The inference functions and fusion techniques developed in WP 2 are applied to the field conditions of the different test sites. Where possible geo-referenced data sets and maps were used for calibration and validation of the geophysical techniques. In some cases, additional analyses can be required to fill the gaps in the datasets and cover the selected dynamic soil properties. The experimental conditions, the results and the costs of the experiments and measurements for each geophysical method (Hyperspectral, GPR, EMI, Geoelectric, Seismic), in terms of man-day, are reported. After a general introduction that indicates the specific content of this deliverable in relationship with the deliverables of WP2 and other deliverables of WP3, each experiment is described in detail. The plan is organized by experimentations but several geophysical methods may have been run at the same site.

Abstract

The present deliverable concerns the first task of the DIGISOIL’s WP1. Requirements of the proposed system according to the data acquisition and management points of view are first studied. These requirements lead to organise the different components of the system in the frame of a functional analysis where objectives, products and functions are clearly presented. Then, a state of the art on the different geophysical sensing techniques able to contribute to the DIGISOIL’s objectives is performed. Each technique is reviewed in terms of measurement principles, processing and applications, strengths and limitations, and availability of commercial and non-commercial sensors. This part leads to identify the techniques being in the scope of the projects from those considered not suitable enough. Finally, for all of these techniques, a study of possible technical solutions is conducted for identifying the best active source, sensors, measuring strategy and equipment. A synthetic table is finally proposed to roughly identify the composition of the integrated system that will be tested in the next field experiments.

Abstract

The purpose of this study concerns the review of all possible techniques for making the inversion of geophysical signals into physical parameters more robust. The information provided by the different sensors are thus be integrated in a complementary way using correction protocols and data fusion strategies. In that way, each sensor should contribute to constrain each other and regularize the overall integrated parameter estimations. The present deliverable concerns the first task of the DIGISOIL’s WP2. During this study, we analyze the requirements for making soil characteristic maps and the way to use and integrate geophysical parameters for this purpose. After a state of the art on the different solutions for assimilating different sources of information for improving the quality of such maps, we propose a review of the capabilities of each method for characterizing soil structures and soil properties. A general processing workflow is established. It constitutes a first technical solution to reach our objectives. It will be tested in the future by using data acquired during the next field acquisition missions. This processing takes into account the different geophysical sensors already identified, supposes that inversion algorithms have already been applied to these data, uses auxiliary data for corrections, calibration or validation.

27. Multiconfiguration electromagnetic induction survey for paleochannel internal structure imaging: a case study in the alluvial plain of the River Seine, France.

Abstract

The La Bassée floodplain area is a large groundwater reservoir controlling most of the water exchanged between local aquifers and hydrographic networks within the Seine River basin (France). Preferential flows depend essentially on the heterogeneity of alluvial plain infilling, whose characteristics are strongly influenced by the presence of mud plugs (paleomeander clayey infilling). These mud plugs strongly contrast with the coarse sand material that composes most of the alluvial plain, and can create permeability barriers to groundwater flows. A detailed knowledge of the global and internal geometry of such paleomeanders can thus lead to a comprehensive understanding of the long-term hydrogeological processes of the alluvial plain. A geophysical survey based on the use of electromagnetic induction was performed on a wide paleomeander, situated close to the city of Nogentsur-Seine in France. In the present study we assess the advantages of combining several spatial offsets, together with both vertical and horizontal dipole orientations (six apparent conductivities), thereby mapping not only the spatial distribution of the paleomeander derived from lidar data but also its vertical extent and internal variability.

Abstract

The La Bassée floodplain area is a large groundwater reservoir controlling most of the water exchanged between local aquifers and hydrographic networks within the Seine River Basin (France). Preferential flows depend essentially on sediment fills, whose characteristics are strongly influenced by paleomeander heterogeneities. A detailed knowledge of the internal heterogeneities of such paleomeanders can thus lead to a comprehensive understanding of its long-term hydrogeological processes. A geophysical survey based on the use of electromagnetic induction was performed on a representative paleomeander, situated close to the city of Nogent-sur-Seine in France. In the present study we assess the advantages of combining several spatial offsets, together with both vertical and horizontal dipole orientations (6 apparent conductivities), thereby mapping not only the spatial distribution of the paleomeander derived from LIDAR data, but also its vertical extent and internal variability.

Abstract

We have developed an inversion process of electromagnetic induction (EMI) data based on a two-step approach with 1D inversion of the entire studied surface and a fast 3D inversion applied over limited areas. This process is similar to that formerly used in resistivity prospection. For the study of soil (environmental, engineering, or archaeological explorations), low-frequency electromagnetic instruments (referred to as Slingram EMI) have highly useful specificities. They are light, are easy to move in the field, and can simultaneously measure the ground's electric conductivity and magnetic susceptibility; they have thus been used to map these properties over large surface areas, within relatively short periods of time, and at reasonable expense. The possibility of combining several coil geometries has opened up the potential for multidepth techniques and systematic 1D inversion, which are found to be sufficiently revealing to allow larger portions of surveyed areas to be analyzed. In the "targeted areas" selected for 3D inversion, the geometries of the 3D features and the resistivity and/or susceptibility contrasts are determined. This step is based on the method of moments, where only 3D heterogeneities are meshed, and only a small number of major characteristics, such as contrast, thickness, width, etc., are sought. We first applied this process to synthetic data, then to data acquired at an experimental test site, and finally to field cases. The rapid 3D inversion complements the 1D inversion by solving a series of issues: correction for the apparent anisotropy generated by the instrument configuration, multiarched anomalies, precise location of lateral changes, and determination of the properties contrasts. Our inversion results highlighted the importance of the instrument geometry. We also have determined that apparent magnetic susceptibility data can be more appropriate for the determination of the volume of man-made features and can be highly complementary to conductivity data.

31. Improvement of cyclostratigraphic studies by processing of high-resolution magnetic susceptibility logging: Example of PEP1002 borehole (Bure, Meuse, France)

Abstract

Abstract: Logging opens wide paths for cyclostratigraphic studies of sedimentary successions. In clay-dominated rocks, magnetic susceptibility (MS) is very informative and the quality of the results can be further enhanced by deconvolution, where the deformation of the original susceptibility versus depth variation by the instrument is filtered out by its impulse response (thin layer response). This is illustrated by processing the data acquired in the PEP1002 borehole (Bure, Meuse, France) using two coils 0.25m apart where high-frequency, 0.5 to 0.8m, period precession cycles (21kyr) can be identified, as well as the 2.5 to 4m period eccentricity (95kyr) ones.
