Apports des hautes résolutions spatiales pour l'étude et la cartographie des algues vertes. Application à la grève de St-Michel(22) ArchiMer
Ruiz, Olivier.
The increasing amounts of agricultural effluents associated with particular hydrodynamical locations are resulting in strong proliferations of suspended green algae Ulva lactuca. During ebb tide, the algae deposit on beaches, creating a nuisance for both tourism and fishermen. Biomass estimates are hence needed both for understanding the phenomenon and for measuring its magnitude. During the spring tide period of September 1993, two high resolutions digital sensors were run jointly on the French A.R.A.T (Remote Sensing and Atmospheric Research Aircraft). A pushbroom instrument called RAMI (run by C.N.E.S.) with spectral bands identical to those of S.P.O.T. and the Canadian C.A.S.I (which possesses a lot of spectral bands) acquired images over the sandy...

Martínez-Montoya,Juan F; Herrero-Isern,Juan; Aceves-de Alba,Jorge; Palacio-Núñez,Jorge; Ruiz-Vera,Víctor M; Olmos-Oropeza,Genaro.
The gypseous soils of San Luis Potosí State, México, are not well map-delimited, despite their broad extent and the specific agricultural and environmental management they require. The present article highlights the location and extent of the gypseous lands in the Altiplano and Zona Media of San Luis Potosí State. For this purpose, soil, geology and vegetation maps as well as studies related to gypsum-rich soils, aerial photographs, and satellite maps (termed 'espaciomapas' in Spanish, these refer to Landsat-5 Thematic Mapper images of Red-Green-Blue:432 composition printed at 1:250,000 scale) were reviewed. Additionally, field and laboratory work were carried out. The maps provided by the Commission for Studies of the National Territory (CETENAL) proved...

Benthic communities and geomorphology of the Tesoro Island Coral Reef, Colombian Caribbean OceanDocs
Sánchez-M., Juan M..
The benthic communities distribution in Tesoro Island (Colombian Caribbean) coral reef was determinad by cartography of reef morphology and functional groups from aerial photographs, theodolite triangulation, and bottom transects over depths ranging from O to 30 m. Tesoro Island is a sand cay reef developed over an emerged reef platform whose basal cone possibly originated by mud diapirism on the continental shelf. The benthic communities are distributed as subzones of the geomorphologic units. The reef crest lies along the breaker zone, formed by Millepora spp. buttresses covered on their tops by Palythoa spp. and seawardly by a turf of Dictyota spp. The rear reef (varying from 0.5-1.5 m ¡n depth) is composed of pavement and grooves with live Porites...

Cartographie des bancs de crépidules dans le bassin de Marennes Oléron: analyse par imagerie acoustique et sondeur de sédiment ArchiMer
Curti, Cécile.
The slipper limpet Crepidula jornicata, gastropod introduced on the North East Atlantic coasts, is considered as an invasive species, especially in shellfish fmming areas in France. Slipper Iimpet populations have been estimated in Marennes Oléron Bay since 1980. In 1995, a sidescan sonar mapping associated to a quantitative estimation of the stocks by « grab » was carried out. This study aims to update the current mapping of slipper limpet beds in the Marennes Oléron Bay using acoustic reading techniques coupled to samples. In autumn 2008, an acoustic campaign was performed through the Ifremer boat named Haliotis and sonograms obtained during the campaign were then analysed using the software CARAIBES. Acoustic images were calibrated through30 grab...

Cartographie et évaluation des principaux mollusques filtreurs du Golfe Normano-Breton ArchiMer
Noel, Philippe; Blanchard, Michel; Berthou, Patrick.
During 1993 and 1994, quantitative sampling were realized in Norman Gulf (Western Channel) to estimate molluscs suspension-feeders. Four bivalves are regularly sampled : Spisula ovalis, Tapes rhomboides, Glycymeris glycymeris and Venus verrucosa. For each species, individual age and weight were noticed. The spreading gastropod Crepidula fornicata was also sampled. The resultant biomass and distribution are proposed. These results will contribute to the evaluation of trophic exchanges in boundary layer and to the proposed modeling, in the program PNOC (National Program for Coastal Oceanography).

Cartographie et évaluation du stock de crépidules en baie du Mont Saint-Michel, en 2004 ArchiMer
Blanchard, Michel; Clabaut, Philippe; Abernot-le Gac, Chantal.
In 2003 and 2004, 3 cruises were organized using observations systems and sampling techniques to carry out cartography and stock assessment of the Slipper-limpet population (Crepidula fornicata) in the bay of Mont-Saint-Michel (Western Channel). This was done as part of the National Programme of Coastal Environment (Programme National d'Environnement Côtier - PNEC). The study helped to update previous data collected in 1995-96 with similar techniques : side-scan-sonar and submarine video for observation, and scuba diving and grabs for samples collection. Results show that during an eight years period, the limpet population spread in the southern part of the bay and that its stock rose about 50%, reaching about 150,000 metric tons, south of a...

Cartographie sous-marine: Etat de l'art et problemes ArchiMer
Renard, V.
The side looking sonars have been developed for greater swath coverage, digital processing of the signals has improved the quality of the images and interferometric techniques have been used to determine the depth of the bottom features. A review of the systems existing today is presented. Documents such as graphs, block diagrams, images, maps, sections, created from data acquired at sea level suffer from a filtering or smoothing effect that restricts the representativity of the measured parameters and therefore limits their interpretation. The greater the depth of the seafloor, the greater the filtering. It is due not only to the nature of the measured phenomenon but also the characteristics of the sensors, to their operation and to the data processing....

Classificação não-supervisionada no delineamento de zonas de manejo. Infoteca-e
SHIRATSUCHI, L. S.; QUEIROS, L. R.; FACCIONI, G. C..
RESUMO: O objetivo deste trabalho foi utilizar o método de classificação não-supervisionada (fuzzy K-means) em dados de produtividade para delineamento de zonas de manejo. O estudo foi conduzido a partir de dados georregerenciados de produtividade de grãos coletados por sensores e DGPS. Foram mapeadas três safras (milho-soja-arroz) em área de plantio direto irrigada por pivô central. Os dados de produtividade foram interpolados pelo inverso da distância resultando em um mapa de resolução espacial de 5 x 5 m. Os valores relativizados em relação à média de produtividade foram comparados ao longo do tempo nos mesmos locais. Como referência, foram escolhidas três classes de produtividade para delinear as zonas de manejo segundo os seguintes critérios:...

Coastal zones inventory by high resolution satellites ArchiMer
Loubersac, Lionel.
The development of tools for assessing impacts on coastal environments is a reality. These impact assessments need both baseline and monitoring studies. Satellite remote sensing data would be useful for coastal inventories (baselines) and monitoring if high spatial and temporal resolutions are yield compatible. An overview of the various sensors that could be used is presented. The constraints linked to the different resolutions are exposed. An example based on Spot simulated data and trends are developed.
