Webpublished Reference NOOS-Drift, an innovative operational transnational multi-model ensemble system to assess ocean drift forecast accuracy.
In case of maritime pollution, man-overboard, or objects adrift at sea, national maritime authorities of the 9 countries bordering the European North West Continental Shelf (NWS) rely on drift model simulations in order to better understand the situation at stake and plan the best response strategy. So far, the drift forecast services are mainly managed at national levels with almost no integration at the transnational level. Designed as a support service to the national drift forecasting services, NOOS-Drift has the ambition to change this paradigm. NOOS-Drift is a distributed transnational multi-model ensemble system to assess and improve drift forecast accuracy in the European North West Continental Shelf. Developed as a one-stop-shop web service, the service allows registered users (national drift model operators or trained maritime authorities) to submit on-demand drift simulation requests to be run by all the national drift forecasting services connected to NOOS-Drift. Within 15 minutes after activation, the NOOS-Drift users shall get access to the drift simulation results of the individual ensemble members, as well as the results of a multi-models joint analysis assessing the ensemble spread and delineating risk areas to locate possible maritime pollution. This operation of such a distributed multi-models service is to our knowledge a world premiere. In this communication, we will present the technical and scientific developments that had to be done to make this service possible, including: - a robust, secure and latency-free communication system that coordinates the execution of the different national models - a strategy to build the multi-model ensemble - a definition of drift forecast accuracy - the joint multi-model analysis tools - the standard file formats and visualisation means. Finally we will illustrate on an example how the NOOS-Drift service could change the decision making process.

Webpublished Reference North Sea Hydrodynamics With Nested Models
The North Sea is an epeiric sea on the European continental shelf, which connects to the Atlantic Ocean through the English Channel in the South and the Norwegian Sea in the North. It hosts key north European shipping lanes, and it is a major fishery and a rich source of energy resources, including wind, wave and solar power. Here we present a nested hydrodynamics model that is calibrated against in situ data for the year 2009, and validated for the years 2010, 2011 and 2015, which present a large range of contrasting North Atlantic Oscillation (NAO) indices. Our results are openly available and provide 10+ years of hydrodynamics data (sea surface elevation, sea water velocity, potential temperature and salinity) with a resolution of 30 arcseconds in the Southern Bight of the North Sea, and 2 arcminutes elsewhere. With our model and resulting dataset, we aim at supporting marine research and policy in a highly, anthropogenically impacted system, allowing stakeholders to take informed decisions to sustainably manage its valuable resources.

Article Reference Nouvel examen des moulages des ossements du squelette néandertalien du Moustier I
Contexte En 1908, l’archéologue suisse Otto Hauser découvrait en Dordogne, dans un contexte stratigraphique discutable, un squelette assez complet d’adolescent néandertalien. Ces vestiges ont été vendus au Musée de Berlin, à la grande indignation des anthropologues français. Le crâne, qui avait déjà été reconstruit à 4 reprises de manière insatisfaisante, a été enlevé par l’Armée Rouge lors de la chute de Berlin, et a été retrouvé en 1965 à Berlin-Est. Quant au squelette post-crânien, il a été sévèrement endommagé pendant les bombardements. Le musée d’anatomie et embryologie Louis-Deroubaix possède des moulages du squelette du Moustier, incluant le crâne tel qu’il avait été reconstruit de manière contestée par l’anatomiste Hermann Klaatsch. Matériel et méthodes Les moulages ont été triés, complétés, comparés par et avec ceux provenant de l’Institut royal des sciences naturelles de Belgique (notamment le moulage endocrânien), mesurés, et ont fait l’objet d’un examen anthropométrique et tomodensitométrique. Cela a permis d’alimenter la banque de données numériques des Néandertaliens ainsi que de générer des reconstructions 3D, qui peuvent, pour le crâne, être comparées aux reconstructions plus récentes, plus précises et mieux fondées. Résultats L’examen des moulages permet de confirmer leur attribution à un néandertalien de sexe probablement masculin âgé d’environ 15 ans. Cette analyse reste à nuancer compte tenu de la reconstruction des os (incluant le « recollage » des noyaux épiphysaires). Discussion et conclusions La possession de moulages originaux par un musée universitaire constitue un atout scientifique et didactique majeur malgré leur imperfection, surtout en raison de la dégradation irrémédiable des ossements originaux.
