Book Reference Ronquières. Documents géologiques
L'exécution du plan incliné de Ronquières sur le canal de Charleroi à Bruxelles a nécessité de multiples études géologiques en vue de la connaissance exacte du sous-sol sous cet important ouvrage. La somme des données géologiques recueillies à cette occasion est sans commune mesure avec les connaissances antérieurement acquises en ce site déjà si particulièrement étudié de la discordance dévonienne du Bord Nord du Bassin de Namur sur le Silurien du Flanc Sud du Massif du Brabant. Le but de ce mémoire est d'assurer la conservation de ces données et d'en tirer profit pour préciser nos connaissances réelles, sans négliger les répercussions des faits nouvellement connus sur l'enseignement géologique traditionnel dont certains concepts devront être précisés ou modifiés. La synthèse de la documentation est présentée en quatre planches annexes : Planche 1. - Situation régionale. En haut: plan de situation et carte géologique de la surface du Primaire. En bas: coupe géologique régionale, réelle dans la partie superficielle, déduite en profondeur d'après les allures régionales. Planche 2. - Coupe géologique axiale du secteur de Ronquières. Planche 3. - Coupes détaillées de la partie Amont. A gauche: coupes sous la Culée, les rangées de colonnes du Pont Canal et la Tête Amont. A droite: coupe axiale et coupes extérieures sous la partie aérienne du Plan Incliné. Planche 4. - Relevé géologique de la tranchée du Plan Incliné.

Article Reference Salinity predicts the distribution of chlorophyll a spring peak in the southern North Sea continental waters
In the North Sea, the coastal waters of Belgium and The Netherlands regularly exhibit intense spring phytoplankton blooms where species such as Phaeocystis recurrently form a potential ecological nuisance. In the Belgian and Dutch continental shelves (BCS and DCS), we observe a direct correlation between the chlorophyll a spring maximum (Chlmax) and the nutrients (DIN and DIP) available for the bloom. As the nutrients are themselves strongly correlated with salinity, a rationale is developed to predict Chlmax from winter salinity. The proposed rationale is first tested in a theoretical case with a 3D-biogeochemical model (3D-MIRO&CO). The method is then applied to independent sets of in situ observations over 20 years in the BCS and the DCS, and to continuous FerryBox data in April 2008. Linear regressions explain the relationships between winter nutrients and winter salinity (R2 = 0.88 to 0.97 with model results, and R2 = 0.83 to 0.96 with in situ data). The relationship between Chlmax and the available nutrients across the salinity gradient is also explained by yearly linear regressions (R2 = 0.82 to 0.94 with model results, and R2 = 0.46 to 0.98 with in situ data). Empirical ‘DIP requirement’ and ‘DIN requirement’ for the spring biomass bloom formation are derived from the latter relationships. They depend i.a. on the losses from phytoplankton during the spring bloom formation, and therefore show some interannual variability (8–12% for DIP and 13–20% for DIN). The ratio between nutrient requirements allows predicting in winter which nutrient will eventually limit the spring biomass bloom along the salinity gradient. DIP will generally be limiting in the coastal zone, whereas DIN will generally be limiting offshore, the switch occurring typically at salinity 33.5 in the BCS and 33.6 in the DCS. N reduction should be prioritized to limit Phaeocystis in the coastal zone, with target winter DIN:DIP ratios below 34.4 molN molP−1 in the BCS, or 28.6 molN molP− 1 in the DCS.

Article Reference SEADETECT: developing an automated detection system to reduce whale-vessel collision risk
With the continuous intensification of marine traffic worldwide, whale-vessel collisions at sea (or “ship strikes”) have become one of the primary causes of mortality for cetaceans and a widely recognised cause of concern for human safety and economic losses. The Mediterranean Sea is a global hotspot for whale-vessel collisions, with one of the highest rates involving large cetaceans, especially the endangered fin whales (Balaenoptera physalus) and sperm whales (Physeter macrocephalus). Evidence indicates that both species are experiencing higher chances of a fatal collision than what predictions have estimated so far, with ship strikes being the main human-induced threat in the area. Regional and international organisations have stressed the need to address the issue by investigating the projected impacts of ship strikes on whale populations and by identifying possible mitigation measures to reduce chances of collision. Amongst the most popular and feasible options, there is the improvement of animal detection during navigation. Here, we present SEADETECT, a LIFE project that aims at developing an automated detection system to reduce vessel collision risk with marine mammals and unidentified floating objects (UFOs), combining state-of-the-art and novel technologies with existing approaches in the study of large whale ecology. This detection system consists of three elements; an automated onboard detection system composed of several sensors, a real- time passive acoustic monitoring (PAM) network at sea and a real-time detection-sharing and alert system (REPCET®). In this paper, we propose the development of a mitigation measure framework tailored for the issue of collision with fin and sperm whales in the north-western Mediterranean Sea, but that has the transferability features necessary for its application in other high-risk areas for ship strikes worldwide.

Book Reference Sédimentologie des formations de Marteau, du Bois d'Ausse et de la partie inférieure de la Formation d'Acoz (Dévonien inférieur) dans l'Est de la Belgique, au bord nord du Massif de Stavelot
Deze samenvatting is niet beschikbaar in het Nederlands. Résumé Les Formations de Marteau et du Bois d'Ausse et la partie inférieure de la Formation d'Acoz (Dévonien inférieur) qui affleurent au nord du Massif de Stavelot, dans l'Est de la Belgique, font l'objet d'une étude sédimentologique et pétrographique détaillée et bien documentée. Les observations de terrain reposent sur les coupes de la Helle et de la Gileppe qui ont été décrites banc par banc. Les caractères lithologiques, complétés par un inventaire exhaustif des structures sédimentaires et par le contenu pétrographique, ont permis de dégager les grands traits de l'évolution sédimentaire et de reconstituer les paléoenvironnements. Dans la Formation de Marteau, on observe le passage d'une sédimentation grossière fluviatile, d'abord peu structurée (rivière en tresses), à une plaine alluviale limitée, ensuite à une plaine alluviale large mais plus côtière et soumise à des influences intertidales (ou estuairiennes). Avec la Formation du Bois d'Ausse, la sédimentation littorale devient presque exclusivement gréseuse, traduisant des apports fluviatiles. On observe ensuite le retour temporaire à une plaine alluviale côtière, soumise à des influences intertidales et enfin à un milieu de type barrière de plage à apports fluviatiles. On atteint ici le maximum transgressif de la mer dévonienne pour la tranche temps et la région étudiée. Le retour à une sédimentation exclusivement continentale s'opère rapidement, marquée par le développement des dépôts rouges de la Formation d'Acoz. Abstract The Lower Devonian Marteau and Bois d'Ausse Formations and the lowermost part of the Acoz Formation outcropping north of the Stavelot Massif in Eastern Belgium are the subject of detailed and well documented sedimentological and petrographical investigations. Continuous sections outcropping in the Helle and Gileppe valleys have been described bed by bed. Lithological characters, sedimentary structures and petrographical content are the basis for understanding the sedimentary evolution and paleoenvironments. In the lower part of the Marteau Formation, coarse-grained siliciclastic deposits are indicative of a braided-river system, evolving towards an alluvial plain of limited extent. Sediments from the upper part of the Marteau Formation reflect a more coastal alluvial plain setting, affected by intertidal influences. The littoral environment is obvious in the lower part of the Bois d'Ausse Formation with a sandy sedimentation resulting mainly from fluvial influx. Temporarily, a coastal alluvial plain develops, attested by intertidal influences. Barrier-beach conditions with fluvial influx characterize the upper part of the Bois d'Ausse Formation. It corresponds to the transgressive maximum for the Lower Devonian sea in the studied area. The return to a continental setting is rapid with the development of the red-coloured sediments which characterize the Acoz Formation.
