Système d'Information à référence spatiale et gestion d'un espace de production ostréicole : le cas du bassin de Marennes Oléron (France)
Provedor de dados: 5
Autores: Loubersac, Lionel; Populus, Jacques; Durand, Christophe; Prou, Jean; Kerdreux, Michel; Le Moine, Olivier.
Maintaining shellfish production activities, ensuring their quality and optimising the management of reserved space use with a perspective of sustainable growth are questions that interest a very significant block of French coastal sites. To achieve such objectives, it must especially be possible to relate the spatial distribution of the farmed stocks and environmental constraints: physical characteristics of the environment, nutritive resources, health constraints, environmental protection constraints...

Predictive modelling of seabed habitats: case study of subtidal kelp forests on the coast of Brittany, France
Provedor de dados: 5
Autores: Meleder Tard, Vona; Populus, Jacques; Guillaumont, Brigitte; Perrot, Thierry; Mouquet, Pascal.
Predictive modelling to map subtidal communities is an alternative to "traditional" methods, such as direct sampling, remote sensing and acoustic survey, which are neither time- nor cost-effective for vast expanses. The principle of this modelling is the use of a combination of environmental key parameters to produce rules to understand species distribution and hence generate predictive maps. This study focuses on subtidal kelp forests (KF) on the coast of Brittany, France. The most significant key parameters to predict KF frequency are (1) the nature of the substrate, (2) depth, (3) water transparency, (4) water surface temperature and (5) hydrodynamics associated with the flexibility of algae in a flow. All these parameters are integrated in a spatial...

GIS in support to data analysis for enhanced sustainability of shrimp farming in the Mekong Delta, Vietnam
Provedor de dados: 5
Autores: Populus, Jacques; Nutpramoon, Raweewan; Martin, Jean-louis; Raux, Pascal; Auda, Yves; Son, Hoang.
Over the last twenty years, extensive shrimp aquaculture has dramatically expanded in the coastal fringe of the Mekong Delta. This occurred primarily at the expense of the mangrove, already severely affected by the Vietnam war. More recently, paddy land has been reclaimed for shrimp aquaculture, a higher currency earner. However, production collapses have frequently occurred and the overall yield has remained far below the expectations for traditional farming. A number of parameters enter into play in the success of this activity, summarized in two questions: i) is the Mekong deltaïc environment - under high continental pressure - suitable to shrimp farming, ii) if not, is it possible to adapt the low technicity of rural poor farmers to reach economic...

Towards prediction of seabed habitats
Provedor de dados: 5
Autores: Populus, Jacques; Hamdi, Anouar; Golding, Neil; Van Lancker, Vera; De Oliveira, Eric.
Marine seabed habitats are highly influenced by the geophysical variables they feature. These are firstly seabed type, topography and exposure, but in the more inshore areas also include water transparency, salinity, temperature etc. Some relations have been established in a top-down approach between adequate combinations of these variables and the higher levels of the Eunis (European Nature Information System) habitat classification which is currently being used to harmonise seabed habitat mapping throughout Europe. These levels have been referred to as "Marine landscapes", as they are aggregations of a number of lower Eunis habitats from levels 4 to 6. More elaborate variables that are thought to have a bearing on habitat types can be computed from the...

Etude bibliographique de quelques espèces planctoniques et benthiques littorales de la Manche - Volume 1 - Espèces phytoplanctoniques
Provedor de dados: 5
Autores: Erard-le Denn, Evelyne; Populus, Jacques.
This catalogue deals mainly with common phytoplanktonic species found in the Channel. It is part of a bibliographical survey on pelagos and benthos. The main idea was to gather the largest possible amount of data on the eco-physiology of each species. To do so, studies were conducted in the main marine region where the species had been found and analysed. We focused on several reference ecological studies conducted in the coastal Channel, on the E.D.F. sites, by the C.N.E.X.O., the I.S.T.P.M. and some university laboratories. A great attention was also paid to the studies on seasonal cycles carried out in laboratories in Plymouth, Helgoland and in the Irish zones. (unverified OCR)

Marine data are needed for many purposes: for acquiring a better scientific understanding of the marine environment, but also, increasingly, as marine knowledge for decision making as well as developing products and services supporting economic growth. Data must be of sufficient quality to meet the specific users' needs. It must also be accessible in a timely manner. And yet, despite being critical, this timely access to known-quality data proves challenging. Europe's marine data have traditionally been collected by a myriad of entities with the result that much of our data are scattered throughout unconnected databases and repositories. Even when data are available, they are often not compatible, making the sharing of the information and data aggregation...

Surveying coastal zone topography with airborne remote sensing for benthos mapping
Provedor de dados: 5
Autores: Populus, Jacques; Laurentin, Astrid; Rollet, Claire; Vasquez, Mickael; Guillaumont, Brigitte; Bonnot-courtois, Chantal.
This paper addresses the need for a finer description of coastal zone relief that is currently of interest for benthic habitat mapping. For example, the distribution of seaweed species in the tidal zone will mostly depend on the terrain's hypsometric level, slope and orientation. These parameters can be used in predictive distribution models, or more simply merged with 2.5/3D imagery to enhance interpretation. Since the required accuracy is of the order of 20-30 cm, two remote sensing techniques, lidar and photogrammetry, were examined and conditions for their application were assessed. Lidar surveys have been shown to provide such accuracy in all instances, whatever the substratum and vegetal cover type, as well as with the slope values currently...

Autores: Andersen, Jesper H.; Manca, Eleonora; Agnesi, Sabrina; Al-hamdani, Zyad; Lillis, Helen; Mo, Giulia; Populus, Jacques; Reker, Johnny; Tunesi, Leonardo; Vasquez, Mickaël.
We have analyzed the development of “Broad-Scale Seabed Habitat Maps” (BSHM) and their potential use in a European context with regard to the EU Marine Strategy Framework Directive (MSFD) implementation, MPA designation and network assessment as well as other applications of BSHMs. The analyses are anchored in BSHMs developed by a series of interlinked EU projects (e.g. UKSeaMap, BALANCE, MESH, Mesh Atlantic, EUSeaMap 2012, and EUSeaMap 2016) and all maps are based on environmental data. Some EU Member States have used BSHMs as part of their MSFD Initial Assessments published in 2012. However, we conclude that BSHMs are a prerequisite for another key MSFD activity, i.e. mapping of potentially cumulative effects of multiple human stressors. Further, BSHMs...

Using EUNIS habitat classification for benthic mapping in European seas: Present concerns and future needs
Provedor de dados: 5
Autores: Galparsoro, Ibon; Connor, David W.; Borja, Angel; Aish, Annabelle; Amorim, Patricia; Bajjouk, Touria; Chambers, Caroline; Coggan, Roger; Dirberg, Guillaume; Ellwood, Helen; Evans, Douglas; Goodin, Kathleen L.; Grehan, Anthony; Haldin, Jannica; Howell, Kerry; Jenkins, Chris; Michez, Noemie; Mo, Giulia; Buhl-mortensen, Pal; Pearce, Bryony; Populus, Jacques; Salomidi, Maria; Sanchez, Francisco; Serrano, Alberto; Shumchenia, Emily; Tempera, Fernando; Vasquez, Mickael.
The EUNIS (European Union Nature Information System) habitat classification system aims to provide a common European reference set of habitat types within a hierarchical classification, and to cover all terrestrial, freshwater and marine habitats of Europe. The classification facilitates reporting of habitat data in a comparable manner, for use in nature conservation (e.g. inventories, monitoring and assessments), habitat mapping and environmental management. For the marine environment the importance of a univocal habitat classification system is confirmed by the fact that many European initiatives, aimed at marine mapping, assessment and reporting, are increasingly using EUNIS habitat categories and respective codes. For this reason substantial efforts...

Emodnet Atlantic checkpoint : data adequacy to EU challenges
Provedor de dados: 5
Autores: Populus, Jacques; Moussat, Eric; Blanc, Frederique; Quimbert, Erwann; Vasquez, Mickael; Meillon, Julien; Soudarin, Laurent.
After a time when observations of the sea have been made for specific purposes, e.g. for specific national purposes or to demonstrate a technological capability, the European Commission has now moved to a new paradigm where data are collected once and used them for as many purposes as possible. This means relying preferably on users rather than on producers to assess existing data sets and data sources and promote recommendations for a better satisfaction of their needs. The EMODNET Atlantic checkpoint (http://www.emodnet-atlantic.eu/) was designed to evaluate the fitness-for-use of current observations and data assembly programs towards 11 marine applications and prioritizing the needs to optimize monitoring systems at the scale of the North Atlantic Ocean.

Estimation des stocks conchylicoles par télédection: résulats et perspectives
Provedor de dados: 5
Autores: Deslous-paoli, Jean-marc; Populus, Jacques; L'Herroux, Michel; Brussieux, Marc.
This papers compares modern techniques of remote sensing (numerical) to more classical ones (photo-interpretation) for the assessment of the intertidal zone land use. The study is limited to homogeneous areas of off-bottom cultivation.  The evaluation of the total area was made using both middle scale aerial photographs, with systematic sampling, and SPOT satellite data. These two methods do not allow to measure the off-bottom rearing design length. It is therefore necessary to get more precise information through high resolution data such as classical high scale photographs numerical scanners (MATRA) or C.C.D. cameras.

Marine landscape maps: methodology and potential use
Provedor de dados: 5
Autores: Hamdi, Anouar; Populus, Jacques; Piel, Steven.
The Marine Landscape is a concept that originated in Canada (Roff and Taylor 2000) and was recently implemented in UK and Europe in the respective frames of the UKSeaMap (Connor 2006) and Mesh projects. It aims to describe the marine environment with respect to its main geophysical features, in terms of both the seabed and water column. Marine landscape maps are not a surrogate for genuine habitat maps which are produced by incorporating biological data from samples to the physical map. They provide a more global vision of our coastal and shelf environment in terms of their main physiographic traits and hence act as a support for national/regional policy and spatial planning. While initially applied on a more global scale (resolution of one nautical mile),...

Provedor de dados: 5
Autores: Populus, Jacques; Loubersac, Lionel; Prou, Jean; Kerdreux, Michel; Le Moine, Olivier.
In Marennes-Oléron, Héral (1986) described the relationship between the annual production and the oysters' biomass over a century. His conclusion is that the drop in the growth of oysters was caused by an "overstorage" considering the trophic capacity of the basin. Moreover, the large intertidal spaces, though providing a great opportunity for mollusc culture, suffer from a large bio-deposition (Sornin 1983) which tends to intensify the sedimentation of the basin. The spatial management of oyster culture could be a key factor for its long-term development. In collaboration with the French Marine Affairs, in charge of the cadastral management, the IFREMER has developed a geographical information system enabling the gathering under the same geographic...

Assessment of tropical shrimp aquaculture impact on the environment in tropical countries, using hydrobiology, ecology and remote sensing as helping tools for diagnosis
Provedor de dados: 5
Autores: Fuchs, Jacques; Martin, Jean-louis M.; Populus, Jacques.
After a period of rapid development of the sites (an increase in both reared surface area and production), tropical shrimp aquaculture is currently being faced with critical problems due to economical and ecological constraints. In many countries with favourable conditions for shrimp aquaculture such as indonesia or Vietnam, sites are often badly selected and/or over-exploited. This conducts to sorne extent to decreases or collapses in the production due to the difficulty in predicting the maximum production capacity of the sites. Furthermore, it appears that production sustainability depends on many factors among which socio-economy and ecolo gy are of prime importance. The STD3 project titled « Assessment of tropical shrimp aquaculture impact on the...

In order to most benefit from the potential offered by the European marine basins in terms of growth and employment (Blue Growth), and to protect the marine environment, we need to know more about the seafloor. European Directives, such as the MSFD, but also the Horizon 2020 roadmap explicitly called for a multi-resolution full coverage of all European seas including bathymetry, geology and habitats. The present work, following on a suite of past initiatives, has made a big step forward in this direction. It has first boosted the collation of existing maps from surveys by setting up a framework and a procedure to encourage people to submit their maps and data. This resulted in a more attractive EMODnet seabed habitat portal and a snowball effect with more...

If marine management policies and actions are to achieve long-term sustainable use and management of the marine environment and its resources, they need to be informed by data giving the spatial distribution of seafloor habitats over large areas. Broad-scale seafloor habitat mapping is an approach which has the benefit of producing maps covering large extents at a reasonable cost. This approach was first investigated by Roff et al. (2003), who, acknowledging that benthic communities are strongly influenced by the physical characteristics of the seafloor, proposed overlaying mapped physical variables using a Geographic Information System (GIS) to produce an integrated map of the physical characteristics of the seafloor. In Europe the method was adapted to...

Marine benthic ecosystems are difficult to monitor and assess, which is in contrast to modern ecosystem-based management requiring detailed information at all important ecological and anthropogenic impact levels. Ecosystem management needs to ensure a sustainable exploitation of marine resources as well as the protection of sensitive habitats, taking account of potential multiple-use conﬂicts and impacts over large spatial scales. The urgent need for large-scale spatial data on benthic species and communities resulted in an increasing application of distribution modelling (DM). The use of DM techniques enables to employ full spatial coverage data of environmental variables to predict benthic spatial distribution patterns. Especially, statistical DMs have...

Geomatics for the management of oyster culture leases and production
Provedor de dados: 5
Autores: Populus, Jacques; Loubersac, Lionel; Prou, Jean; Kerdreux, Michel; Le Moine, Olivier.
The coastal zone of Charente-Maritime in France has a leading position in oyster culture production. Yet it is being jeopardized by a number of problems such as overstocking, inadequate distribution of culture types, wild stock in excess, and strong siltation processes. Some of these problems result from a lack of communication and realization within the professional community, others due to obsolete management tools. The introduction of geomatics is believed to help provide some answers, besides alleviating the classical task of lease management. This chapter shows how the system was built, the spatial data geo-referenced and linked to administrative data. Examples of queries on the spatial data base reveal some otherwise invisible facts and allow...

Modelling Seabed Physical Habitat
Provedor de dados: 5
Autores: Vasquez, Mickael; Hamdi, Anouar; Populus, Jacques.
Within the marine environment, the EUNIS classification system attempts to define key environmental drivers that describe natural benthic habitats. The hierarchical nature of the system is initially broad, but becomes increasingly complex at finer biological scales such as communities and species. This project addressed the higher EUNIS levels. Each of the contributing physical parameters were split into categories using threshold values defined with the help of benthic ecologists familiar with the relative influence of such factors on seabed biology. Climatologies were confronted to in situ samples and observations to derive most reliable values. Historic data sets were collated, stitched and harmonised into mosaics which comprehensively covered the area...

Using airborne laser altimetry to estimate Sabellaria alveolata (Polychaeta: Sabellariidae) reefs volume in tidal flat environments
Provedor de dados: 5
Autores: Noernberg, Mauricio Almeida; Fournier, Jerome; Dubois, Stanislas; Populus, Jacques.
This study has exploited aerial photographs and LiDAR digital elevation model to quantify intertidal complex landforms volume. A first volume estimation of the main sabellariid polychaete reef complex of the Bay of Mont-Saint-Michel - France is presented. The Sabellaria alveolata is an engineering species that heavily modifies its environment. This gregarious tube-building annelid forms dense and solid reefs of bioclastic coarse sand which can reach several km(2). Since 1970 a very strong decline of reefs has been observed. The authorities have curbed fishing activities without any noticeable changes in reef health status. The S. alveolata reef volume is estimated to be 132 048 m(3) (96 301 m(3) for Sainte-Anne reef and 35 747 m(3) for Champeaux reef)....

Estimation of the diffuse attenuation coefficient K-dPAR using MERIS and application to seabed habitat mapping
Provedor de dados: 5
Autores: Saulquin, Bertrand; Hamdi, Anouar; Gohin, Francis; Populus, Jacques; Mangin, Antoine; D'Andon, Odile Fanton.
The availability of light in the water column and at the seabed determines the euphotic zone and constrains the type and the vertical distribution of algae species. Light attenuation is traditionally quantified as the diffuse attenuation coefficient of the downwelling spectral irradiance atwavelength 490 nm(Kd490) or the photosynthetically available radiation (KdPAR). Satellite observations provide global coverage of these parameters at high spatial and temporal resolution and several empirical and semi-analytical models are commonly used to derive Kd490 and KdPAR maps from ocean colour satellite sensors. Most of these existing empirical or semi-analytical models have been calibrated in open ocean waters and performwell in these regions, but tend to...

Autores: Populus, Jacques.
Les estrans et les zones basses et inondables attenantes ont toujours souffert d'un large désintérêt de la part des gestionnaires de l'espace. A la faveur des catastrophes répétées de ces dernières années, un regain d'intérêt s'est fait jour pour à la fois prévoir et établir des scénarii, gérer le milieu en temps de crise, voire dédommager par la suite. La connaissance fine des zones côtières, au plan patrimonial comme à celui des activités économiques, est essentielle. Des programmes se mettent en place tel le Rebent, qui vise à réaliser un inventaire renouvelable des habitats des zones découvrantes et des petits fonds. Parmi les données de base nécessaires à une telle entreprise, on trouve les donnée physiques de topographie et de géomorphologie. En zone...

EUSeaMap 2019 is the third iteration of EUSeaMap. All versions have been produced as part of the EMODnet Seabed Habitats project, which is one of several thematic lots in EMODnet. The project has brought together a European consortium of specialists in benthic ecology and seabed habitat mapping. The partners first collaborated in EMODnet phase 1 (2009-2012) to deliver a prototype predictive seabed habitat map in four trial basins (Greater North Sea, Celtic Seas, Baltic, Western Mediterranean). This predictive model was named EUSeaMap (Cameron and Askew, 2011). In EMODnet Phase 2 (2012-2016), the consortium extended EUSeaMap coverage to all European regions (Populus et al, 2017). In the new version, the spatial coverage was extended further North in order...

Autores: Tong, P. H. S; Auda, Y; Populus, Jacques; Aizpuru, M; Al Habshi, A. Al; Blasco, F.
This study is an attempt to produce an assessment of the impact of shrimp aquaculture in the Mekong Delta (Viet Nam) on mangrove ecosystems. For this exercise we selected two sub-areas (Ca Mau and Tra Vinh provinces) encompassing a variety of land uses and ecological conditions. Twenty stations in Tra Vinh and 15 stations in Ca Mau have been surveyed several times from September 2000 to March 2002. Field investigations included mangrove soils studies, measurements of pH and salinity of the water, analysis of mangrove flora, and density and structure of the vegetation. Four Systeme Probatoire de l'Observation de la Terre (SPOT) scenes were used for the discrimination of mangrove types and for the delineation of landscape units. For the first time, five...

Application of spot data to a base-line ecological study of the mahakam delta mangroves (east kalimantan, indonesia)
Provedor de dados: 5
Autores: Dutrieux, Eric; Denis, Jacques; Populus, Jacques.
The objective of this study is to explain the spatial and temporal distribution of the vegetal communities of the Mahakam delta, chiefly on the basis of its physical and chemical characteristics. The delta is at present subjected to intense oil exploitation, and it is necessary to describe the situation on the site and its natural evolution in arder to be able to evaluate the damage that accidentai oil spillage could cause. The authors provide elements to define the sensitive zones whose protection should be a matter of priority. SPOT imagery was chosen as the tool allowing such an approach on a delta measuring 1 500 km2 SPOT satellite images of the Mahakam delta show that different plant communities succeed one another bath in time and in space. The...

Predictive modelling of coastal habitats using remote sensing data and fuzzy logic: A case for seaweed in Brittany (France)
Provedor de dados: 5
Autores: De Oliveira, Eric; Populus, Jacques; Guillaumont, Brigitte.
The aim of this study is to model the seaweed species distribution with respect to environmental parameters. We focused on fixed species of algae, such as fucoids. Firstly, we identified environmental parameters, such as substratum nature, immersion time, exposure, etc., which determine the seaweed distribution. Secondly, we used field sampling to compute the distribution laws for seaweed according to the environmental parameters selected. Thirdly, we used the distribution laws and the environmental parameters to perform predictive mapping of seaweed belts with a fuzzy logic method.   Seaweed presence is directly dependent on the nature of the substratum. In the intertidal domain we used an alternative, because seaweed beds can be observed directly. We...
