Middle‐atmosphere dynamics observed with a portable muon detector
No full textInternational audienceIn the past years, large particle‐physics experiments have shown that muon rate variations detected in underground laboratories are sensitive to regional, middle‐atmosphere temperature variations. Potential applications include tracking short‐term atmosphere dynamics, such as Sudden Stratospheric Warmings. We report here that such sensitivity is not only limited to large surface detectors under high‐opacity conditions. We use a portable muon detector conceived for muon tomography for geophysical applications and we study muon rate variations observed over one year of measurements at the Mont Terri Underground Rock Laboratory, Switzerland (opacity of ∼700 meter water equivalent). We observe a direct correlation between middle‐atmosphere seasonal temperature variations and muon rate. Muon rate variations are also sensitive to the abnormal atmosphere heating in January‐February 2017, associated to a Sudden Stratospheric Warming. Estimates of the effective temperature coefficient for our particular case agree with theoretical models and with those calculated from large neutrino experiments under comparable conditions. Thus, portable muon detectors may be useful to 1) study seasonal and short‐term middle atmosphere dynamics, especially in locations where data is lacking such as mid‐latitudes; and 2) improve the calibration of the effective temperature coefficient for different opacity conditions. Furthermore, we highlight the importance of assessing the impact of temperature on muon rate variations when considering geophysical applications. Depending on latitude and opacity conditions, this effect may be large enough to hide subsurface density variations due to changes in groundwater content, and should therefore be removed from the time‐series
Seroprevalence of typhus group and spotted fever group Rickettsia exposures on Reunion island
No full textInternational audienceOBJECTIVE:Murine typhus has been increasingly reported on Reunion island, Indian ocean, following documentation of eight autochthonous infections in 2012-2013. We conducted a serosurvey to assess the magnitude of the seroprevalence of rickettsioses in the population. Two hundred and forty-one stored frozen sera taken from the 2009 Copanflu-RUN cohort were analysed using an immunofluorescence assay allowing to distinguish typhus group (TGR) and spotted fever group Rickesttsiae (SFGR). Seropositivity was defined for a dilution titre of Rickettsia IgG antibodies ≥ 1:64. Seroprevalence was weighted to account for the discrepancy between the Copanflu-RUN subset and the general population, as to infer prevalence at community level. Prevalence proportion ratios (PPR) were measured using log-binomial models.RESULTS:The weighted seroprevalences of typhus group rickettsioses and spotted fever group rickettsioses were of 12.71% (95% CI 8.84-16.58%) and 17.68% (95% CI 13.25-22.11%), respectively. Pooled together, data suggested that a fifth of the population had been exposed at least to one Rickettsia group. Youths (< 20 years) were less likely seropositive than adults (adjusted PPR 0.13, 95% CI 0.01-0.91). People living in the western dryer part of the island were more exposed (adjusted PPR 2.53, 95% CI 1.07-5.97). Rickettsioses are endemic on Reunion island and circulated before their first identification as murine typhus in year 2011. Surprisingly, since isolation of Rickettsia africae from Amblyomma variegatum in year 2004 or isolation of Rickettsia felis from Amblyomma loculosum, no autochthonous cases of African tick-bite fever or flea-borne spotted fever has yet been diagnosed
Amélioration de la qualité des stations permanentes françaises à large bande possédant des installations à forage peu profond
No full textDans le cadre de l’intégration aux dispositions européens EPOS, Résif s'est transformé en octobre 2023 en Epos-France, une nouvelle infrastructure de recherche aux contours thématiques plus larges et en accord avec ceux de sa grande sœur européenne.International audienceWithin the framework of the Résif (French seismological and geodetic network) research infrastructure, a major extension of the French permanent broadband network (RLBP) has been initiated in 2011 with the objective to reach ~190 stations by 2020. This network will allow a more homogeneous covering of metropolitan France, encompassing a wide variety of tectonic and geological units. Presently the RLBP network consists in 124 operating stations.For each new potential site a test was conducted for ~3 weeks, usually burying the broadband sensor at 50-80 cm depth directly in the ground or within a light temporary vault.For the final set-up, we tested various hosting infrastructures at three prototype sites and decided to promote the installation of a posthole sensor in a steel-cased shallow borehole, 5-20m deep, for all the sites in open areas. 43 stations have already been installed this way and have been operated for 5 to 20 months.Résif is a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the Internal Earth. Résif is based on high-tech observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic events, on French territory. Résif is part of the European (EPOS - European Plate Observing System) and global systems of instruments used to image the Earth's interior as a whole and to study many natural phenomena.Dans le cadre des infrastructures de recherche du Résif (Réseau sismologique et géodésique français), une extension majeure du réseau haut débit permanent français (RLBP) a été initiée en 2011 avec pour objectif d'atteindre ~190 stations en 2020. Ce réseau permettra une couverture plus homogène de la France métropolitaine, englobant une grande variété d'unités tectoniques et géologiques. Actuellement, le réseau RLBP compte 124 stations opérationnelles.Pour chaque nouveau site potentiel, un test a été effectué pendant environ 3 semaines, généralement en enterrant le capteur large bande à une profondeur de 50 à 80 cm directement dans le sol ou dans une voûte temporaire légère.Pour la mise en place finale, nous avons testé différentes infrastructures d'hébergement sur trois sites prototypes et avons décidé de promouvoir l'installation d'un capteur dans un puits de forage peu profond, 5-20m de profondeur, en acier, pour tous les sites en zones ouvertes. 43 stations ont déjà été installées de cette façon et ont été exploitées pendant 5 à 20 mois.Résif est une infrastructure de recherche nationale dédiée à l’observation et la compréhension de la structure et de la dynamique Terre interne. Résif se base sur des réseaux d’observation de haut niveau technologique, composés d’instruments sismologiques, géodésiques et gravimétriques déployés de manière dense sur tout le territoire français. Les données recueillies permettent d’étudier avec une haute résolution spatio-temporelle la déformation du sol, les structures superficielles et profondes, la sismicité à l’échelle locale et globale et les aléas naturels, et plus particulièrement sismiques, sur le territoire français. Résif s’intègre aux dispositifs européens (EPOS - European Plate Observing System) et mondiaux d’instruments permettant d’imager l’intérieur de la Terre dans sa globalité et d’étudier de nombreux phénomènes naturels
