Issues About Retrieving Sea Surface Salinity in Coastal Areas From SMOS Data Auteur(s) : Zine, S Boutin, J Waldteufel, P Vergely, J.l. Pellarin, T Lazure, Pascal Éditeur(s) : IEEE Résumé : This paper aims at studying the quality of the sea surface salinity (SSS) retrieved from soil moisture and ocean salinity (SMOS) data in coastal areas. These areas are characterized by strong and variable SSS gradients [several practical salinity units (psu) on relatively small scales: the extent of river plumes is highly variable, typically at kilometric and daily scales. Monitoring this variability from SMOS measurements is particularly challenging because of their resolution (typically 30-100 km) and because of the contamination by the nearby land. A set of academic tests was conducted with a linear coastline and constant geophysical parameters, and more realistic tests were conducted over the Bay of Biscay. The bias of the retrieved SSS has been analyzed, as well as the root mean square (rms) of the bias, and the retrieved SSS compared to a numerical hydrodynamic model in the semirealistic case. The academic study showed that the Blackman apodization window provides the best compromise in terms of magnitude and fluctuations of the bias of the retrieved SSS. Whatever the type of vegetation cover, a strong negative bias, greater than 1 psu, was found when nearer than 36 km from the coast. Between 44 and 80 km, the type of vegetation cover has an impact of less than a factor 2 on the bias, and no influence further than 80 km from the coast. The semirealistic study conducted in the Bay of Biscay showed a bias over ten days lower than 0.2 psu for distances greater than 47 km, due to an averaging over various geometries (coastline orientation, swath orientation, etc.). The bias showed a weak dependence on the location of the grid point within the swath. Despite the noise on the retrieved SSS, contrasts due to the plume of the Loire River and the Gironde estuary remained detectable on ten-day averaged maps with an rms of 0.57 psu. Finally, imposing thresholds on the major axis of the measurements brought little improvement to the bias, whereas it increased the rms and- could lead to strong swath restriction: a 49-km threshold on the major axis resulted in an effective swath of 800-900 km instead of 1200 km.

Tsunami hazard assessment of Canada Auteur(s) : Leonard, Lucinda J. Rogers, Garry C. MAZZOTTI, Stephane Auteurs secondaires : Geological Survey of Canada, Natural Resources Canada, Sidney ; Université du Québec University of Victoria [Canada] (UVIC) Risques ; Géosciences Montpellier ; Université des Antilles et de la Guyane (UAG) - Institut national des sciences de l'Univers (INSU - CNRS) - Université de Montpellier (UM) - Centre National de la Recherche Scientifique (CNRS) - Université des Antilles et de la Guyane (UAG) - Institut national des sciences de l'Univers (INSU - CNRS) - Université de Montpellier (UM) - Centre National de la Recherche Scientifique (CNRS) Éditeur(s) : HAL CCSD Springer Verlag Résumé : We present a preliminary probabilistic tsunami hazard assessment of Canadian coastlines from local and far-field, earthquake, and large submarine landslide sources. Analyses involve published historical, palaeotsunami and palaeoseismic data, modelling, and empirical relations between fault area, earthquake magnitude, and tsunami run-up. The cumulative estimated tsunami hazard for potentially damaging run-up (≥1.5 m) of the outer Pacific coastline is ~40-80 % in 50 years, respectively one and two orders of magnitude greater than the outer Atlantic (~1-15 %) and the Arctic (<1 %). For larger run-up with significant damage potential (≥3 m), Pacific hazard is ~10-30 % in 50 years, again much larger than both the Atlantic (~1-5 %) and Arctic (<1 %). For outer Pacific coastlines, the ≥1.5 m run-up hazard is dominated by far-field subduction zones, but the probability of run-up ≥3 m is highest for local megathrust sources, particularly the Cascadia subduction zone; thrust sources further north are also significant, as illustrated by the 2012 Haida Gwaii event. For Juan de Fuca and Georgia Straits, the Cascadia megathrust dominates the hazard at both levels. Tsunami hazard on the Atlantic coastline is dominated by poorly constrained far-field subduction sources; a lesser hazard is posed by near-field continental slope failures similar to the 1929 Grand Banks event. Tsunami hazard on the Arctic coastline is poorly constrained, but is likely dominated by continental slope failures; a hypothetical earthquake source beneath the Mackenzie delta requires further study. We highlight areas susceptible to locally damaging landslide-generated tsunamis, but do not quantify the hazard.

Les Caraïbes centraméricaines : fragments à géométrie variable Auteur(s) : Michel, Aurélia Éditeur(s) : Université des Antilles Études caribéennes Résumé : Afin de mettre en perspective les différents articles du dossier, le texte souligne les différentes étapes qui définissent la situation de la façade caraïbe à la fois au sein des Etats-nations et de la région centraméricaine. Depuis une position de marge ou d’enclave liée à la fois à la géographie et aux logiques de l’empire espagnol, cet ensemble territorial s’est construit à partir de fragments plus ou moins connectés entre eux et aux espaces régionaux maritimes (caribéen ou atlantique). Au cours de leur construction, les différents Etats-nations n’envisagent d’abord la façade caraïbe que dans sa dimension de connexion transisthmique. Pourtant, on constate au vingtième siècle différents processus d’intégration territoriale qui visent à relier espace continental et façade caraïbe, processus qu’il faut associer à de nouvelles dynamiques démographiques. Les sociétés d’interface qui en résultent, voient leurs composantes « ladinas », indiennes, ou afro-descendantes se réorganiser. Enfin, ces fragments qui composent la façade prennent de nouvelles couleurs à la lumière des projections faites par d’autres acteurs (ONG) ou à d’autres échelles (région américaine). In order to put into perspective the different papers of the issue, this text highlights the successive stages by which the Caribbean coastline of Central American has been constructed, under the several States-nations and as a part of the Central American region. As a margin or enclave due to geographical characters as to the logics of Spanish Empire, these territories have been made from fragments more or less connected between them or to other regional maritime spaces (Caribbean or Atlantic). When growing, the States-nations in the region first exclusively consider their Caribbean coastline as a transisthmic connection. Yet, during the twentieth century, various process of territorial integration aim to connect continental spaces and maritime coastline, associating demographical dynamics. Societies of interface result of these process, where their ladina, indian, afro components are reorganized. Finally, theses fragments as elements of the façade take a new color in the look of new actors (NGO) or from other scales and spaces (Atlantic region, Caribbean Sea). Para poner en perspectiva los diferentes artículos del numero temático, este texto subraya las varias etapas en que definieron la situación de la costa caribeña, a la vez en cada Estado-Nacion y al nivel de la región. Con una posición de margen o enclave, que se explica tan por motivos geográficos que por las lógicas del imperio español, este conjunto territorial se ha construido a partir de fragmentos más o menos conectados entre sí e con los espacios regionales marítimos (caribeño o atlántico). Cuando se desarrollaron, los Estados-naciones consideraban las costas caribeñas solo por su potencial transístmico. Sin embargo, en el siglo veinte, llevaron a cabo varios procesos de integración territorial que les permiten vincular su espacio continental con la fachada atlántica, y eso asociándose a importantes dinámicas poblacionales. Resultan de estos procesos sociedades de interfaz, cuyos componentes ladinos, indígenas y afros se ven reorganizados. Por fin, los fragmentos que componen la costa caribeña toman otro color a la luz de proyectos llevados por actores ajenos (ONG) o desde espacios y escalas diferentes (Espacio atlántico, región americana).

Heavy metals distribution in mangrove sediments along the mobile coastline of French Guiana Auteur(s) : Marchand, Cyril Lallier Verges, E Baltzer, F Alberic, P Cossa, Daniel Baillif, P Éditeur(s) : Elsevier Résumé : The accumulation of nine heavy metals in fine-grained sediments from the mangrove fringed coast of French Guiana is evaluated. The dynamic features of the South American tropical coastline, from the Amazon to the Orinoco Rivers, result in mangrove sediments being alternately submitted to phases of erosion and net sedimentation a few tens of years long. This process influences the distribution of the heavy metals associated with these frequently re-mobilized deposits. Sedimentary cores and mangrove plant samples were collected, at different seasons, in various swamps characterized by different properties (content of sedimentary organic matter, distance from sea water and fresh water). The ranges of measured concentrations expressed in mu mol g(-1) were the following: Cu (0.06 to 0.61), Co (0.12 to 0.68), Pb (0.08 to 0.18), Ni (0.32 to 0.76), Cr (0.61 to 1.40), Zn (1.25 to 5.94), Mn (4.36 to 45.4) and Fe (441 to 1128). No differences were found between sediments from mangroves developing upstream and downstream of urban areas, i.e. Cayenne and Kourou. This suggests that the content of mangrove sediments in heavy metals along the coastline of French Guiana is essentially the result of the continuous alternation of accumulation and transport phases occurring upstream after departing from the Amazon watershed. The sources of this heavy metals content are thus difficult to identify. However it is well known that the alluvium produced by the natural erosion of the Amazonian soils is naturally enriched in mercury. Also, the run-off from gold mining activities is known to contribute to mercury pollution. Ranges in total Hg were between 0.15 and 2.57 nmol g(-1), with mean values close to 0.41 nmol g(-1), and were clearly correlated with total organic carbon except for some outstanding high values, which may be a result of rapid geochemical changes. Heavy metal concentrations showed variations with depth. The redox conditions and the decay processes affecting the organic matter control the cycling of iron and manganese, which in turn control the concentrations and associations of heavy metals. These preliminary results suggest that the variations in heavy metal content with depth or between mangrove areas result largely from diagenetic processes rather than changes in metal input resulting from local human activities.

It results original because of a dynamic influenced by the system of the amazon muds' dispersion. The coastline's variations are important and the mangrove growing there constitutes various facies. To understand the structure and dynamic of this forest, a test-site has been selected at the Kaw river's estuary. Field measurements of structure parameters permited to identify 3 major types of mangrove forests with different developement stages. Relations between the measured parameters show the facies'dynamic with a self-thinning phnomenon then a gap regeneration. Correlations between structure parameters and corresponding spectral parameters extracted from an IKONOS image have been tested. The use of texture indexes are discussed. Then, a classification of the image reveals the spatial distribution of the facies Parallely, the constitution of a temporal series from 1950 to 2001, base on various remote sensed datas, shows the evolution of the coastline and the associated mangrove. During this period, succeed accretion phases (1950-1981; 1991-2001) and erosion phase (1981-1991). A theorical ages map of the forest stands are also established. Relating with the facies map, it explains the complex evolution of limited Rhizophora zones. A comparison with Sinnamary test-site is made and futurs researches considered. En Guyane française, la mangrove couvre l'essentiel du littoral. Elle tire son originalité d'une dynamique influencée par le système de dispersion des boues amazoniennes. Les variations de la ligne de côte sont alors importantes et les mangroves s'y développant constituent des faciès variés. Pour mieux comprendre la structure et la dynamique de ces mangroves, un site atelier a été choisi au niveau de l'estuaire de la rivière de Kaw. Les mesures sur le terrain de paramètres de structure des peuplements permettent d'identifier 3 grands types de forêt avec différents stades de développement. Des relations entre les différents paramètres mesurés mettent en évidence la dynamique de ces faciès, basée sur un phénomène d'auto-éclaircie puis une régénération par chablis. Un essai de corrélation entre paramètres de structure et paramètres spectraux correspondant sur une image IKONOS a été faite. L'apport des indices de texture est discuté. Une classification de l'image montre la distribution spatiale des faciès. Parallèlement, la reconstitution d'une série temporelle de 1950 à 2001 à partir de données de télédétection variées permet de suivre l'évolution de la côte et de la mangrove associée. Pendant cette période se succèdent phases d'accrétion (1950-1981 ; 1991-2001) et phase d'érosion (1981-1991). Une carte des âges théoriques des peuplements est également établie. Mise en relation avec la carte des faciès, elle explique notamment l'évolution complexe des zones limitées de mangrove à Rhizophora. Une comparaison avec le site de Sinnamary est faite et de futures recherches envisagées. https://hal.archives-ouvertes.fr/hal-01189238 hal-01189238 https://hal.archives-ouvertes.fr/hal-01189238 PRODINRA : 18075 | Partager |

INRA, CFCS Description : Practical uses for Sargassum are sought regionally as our coastlines continue to be flooded by sargassum blooms floating ashore. This study investigated the potential benefits of Sargassum (Sargassum spp.) mulch in sweet potato production at Golden Ridge, St. George, Barbados, during a drought period (November 2015-March 2016). Treatment consisted of combinations of two cultivars of sweet potato (?E? and ?CBS 32?, main-plots) and washed/unwashed Sargassum mulches (sub-plots) of different ages (approximately 4 weeks old and fresh, sub-sub-plots) with four replications. Sargassum mulch was applied to the furrows of plots (6m2) four weeks after planting at a rate of 10 t ha-1 and yield, growth and soil parameters were monitored at periodic intervals. Yield (t ha-1) was highest for the 4-weeks old Sargassum mulch treatment, and the number of marketable tubers was highest for the unwashed 4-weeks old Sargassum treatment. The number of tubers with Euscepes postfaciatus (Scarabee) pest damage was decreased by the Sargassum mulch treatments especially for the 4-weeks old unwashed Sargassum. Vine growth was taller for cultivar ?E? and for the washed Sargassum treatments. Chlorophyll indices were higher in ?CBS 32? than in cultivar ?E? and were lower in Sargassum treated plots. Moisture content in the top 10cm of soil was consistently low and greater in plots of cultivar ?E? than in those of ?CBS 32?. There appears to be some potential for the use of aged Sargassum mulches for improving growth, pest management and yields of sweet potato and further investigations are needed.
