| The oceanographic cruise Califa 2000, as the previous cruise, which concerned the "Parc National de Port-Cros", had for its principal objective to furnish some elements susceptible to help in the control of Caulerpa taxifolia expansion and in the protection of particularly sensitive areas (national parks, patrimonial sectors, regions of socio-economic importance). The cruise lasted from the 4th to the 21st of September 2000 in the rade d'Hyeres, Porquerolles island included, and the rade of Toulon. This detailed prospection gives a location of C. taxifolia and C. racemosa, a new invasive seaweed. (C) 2003 Editions scientifiques et medicales Elsevier SAS. All rights reserved. |

| 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... |

| 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... |

| Following a preliminary mapping survey using a combination of acoustic techniques, spatial patterns of sedimentologic and biological characteristics of the Bay of Douarnenez were studied in 2001 from a series of grab samples and underwater video recording aiming at calibrate the acoustic facies of the bottom and at characterized them from a biological point of view. Results obtained from community structure analysis showed that four principal ecological groups dominate : The coarse sands community with Branchiostoma lanceolatum, Glycymeris glycymeris and Glycera lapidum, the fine to medium sand community with Nephtys cirrosa, Ophelia borealis and Gastrosaccus spinifer, the mixed muddy sand and gravel community with Amphiura filiformis, Edwardsia sp. and... |

| lfremer carries out a yearly bottom trawl survey named Channel Ground Fish Survey (CGFS) in order to collect essential biological data on major exploited fish species in the Eastern Channel. These data are also provided to feed the indispensable historie series to the yearly assessment of resources. This report presents results of the CGFS surveys for 1997 and 1998, under two aspects: a multispecific approach of the biological assemblages and integrating an interannual analysis, then a monospecific analysis of 7 species of commercial interest, as whiting, pout, cod, red gurnard, plaice, black bream, red mullet.

| In the marine environment, positive law generates multiple zones and regulatory limits that overlap in space, justifying a cartographic representation as a relevant approach to promote understanding (synthetic vision), analysis (highlighting legal anomalies, inconsistencies and redundancies), dissemination and communication to different audiences (awareness-raising). The article presents a methodology leading to the mapping of marine and coastal environmental law in West Africa, using a geographic information base to produce static or interactive cartographic representations via a Geographic Data Infrastructure (GDI). It shows the contribution of this type of mapping to a transversal approach in a multi-activity, multi-sectoral and multi-scale context. A... |

| 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.... |
