A new morphometric study of Carioca Lake, Parque Estadual do Rio Doce (PERD), Minas Gerais State, Brazil - DOI: 10.4025/actascibiolsci.v32i1.4990 Biological Sciences
Bezerra-Neto, José Fernandes; UFMG; Briguenti, Ludmila Silva; UFMG; Pinto-Coelho, Ricardo Motta; UFMG.
Carioca Lake is located within the limits of the Rio Doce State Park, in the eastern part of the state of Minas Gerais. This park, one of the largest natural reserves of the Atlantic Rain Forest in Brazil, is a hotspot of tropical biodiversity. The purpose of this study was to update existing information on the bathymetry and morphometric features of the lake, using differential GPS (DGPS) technology for data collection, coupled to a digital echo sounder. The bathymetry was based on the acquisition of 1106 points, where the depths as well as the geographic coordinates were obtained. The new study allowed the refinement of existing primary and secondary morphometric data for this lake.

Morphometry and mixing regime of a tropical lake: Lake Nova (Southeastern Brazil) Anais da ABC (AABC)
GONÇALVES,MONICA A.; GARCIA,FÁBIO C.; BARROSO,GILBERTO F..
ABSTRACT Lake Nova (15.5 km2) is the second largest lake in the Lower Doce River Valley (Southeastern Brazil). A better understanding of ecosystem structure and functioning requires knowledge about lake morphometry, given that lake basin form influences water column stratification. The present study aims to contribute to the understanding of relationship between morphometry and mixing patterns of deep tropical lakes in Brazil. Water column profiles of temperature and dissolved oxygen were taken on four sampling sites along the lake major axis during 2011, 2012 and 2013. The bathymetric survey was carried out in July 2011, along 131.7 km of hydrographic tracks yield 51,692 depth points. Morphometric features of lake size and form factors describe the...

A commented list of Scaphopoda (Mollusca) found along the Brazilian coast, with two new synonymies in the genus Gadila Gray, 1847 Biota Neotropica
Souza,Leonardo Santos de; Araújo,Isabella Campos Vieira; Caetano,Carlos Henrique Soares.
This review aims to present an updated checklist of scaphopods, based mainly on literature database. There is a total of 40 species (six families) for Brazil, including information about the distribution and bathymetric range of each taxon. We propose two synonyms with the aid of morphometry of the shell, for the genus Gadila: G. longa as junior synonym of G. elongata and G. robusta as junior synonym of G. pandionis.

Caracterización integral de las lagunas del estado de Hidalgo Colegio de Postgraduados
Montero Aguirre, Saúl.
Los cuerpos de agua son importantes para el almacenamiento y abastecimiento de agua potable, riego, generar energía eléctrica, además de ser importantes para disipar la fuerza de las grandes avenidas, estos cuerpos pueden ser utilizados como criaderos de peces y áreas de recreación, de lo cual muchas comunidades obtienen recursos adicionales para sobrevivir. A los ríos descargan las aguas negras de las comunidades que a su paso se encuentran, llevando grandes cantidades de sedimentos y de contaminantes. Las aguas del Río Tulancingo llegan a la Laguna de Metztitlan, la cual en tiempo de lluvias tiende a provocar inundaciones aguas arriba. Este cuerpo de agua al igual que la mayoría de los cuerpos de agua que existen en México, está perdiendo su...

Cystoseira baccata meadows along the French Basque coast (Bay of Biscay) as a reference for the implementation of the Water Framework and Marine Strategy EU directives ArchiMer
De Casamajor, Marie-noelle; Derrien-courtel, Sandrine; Lalanne, Yann; Maria Gorostiaga, José; Le Gal, Aodren; Huguenin, Laura; Quintano, Endika; Lissardy, Muriel.
Cystoseira baccata, a biological quality element for the implementation of the Water Framework and Marine Strategy EU Directives, is a dominant species in the subtidal rocky bottoms of the Basque coast. As part of this issue and given the need to better understand the functional character of benthic rocky ecosystems and use them as a reference to anthropogenic changes, two samplings campaigns were conducted in 2014 and 2017. Several population parameters (i.e. frond density, frond length frond-length/total frond-length ratio and taxonomic richness of epibionts) of C. baccata were studied from three sites monitored within the Water Directive Framework in relation to bathymetry during the two campaigns. The results showed a significant influence of...

Évolution récente et sédimentation des plates-formes continentales de la Corse ArchiMer
Pluquet, Fabrice.
This work aimed at displaying and studying morphological and sedimentological features of Corsican seafloor from the coast to depths of -100m. It also aimed at a better knowledge of sediment dynamics under hydrodynamic conditions, and at a reconstitution of the late Quaternary shorelines evolution. Careful analysis of the bathymetry has revealed a very contrasted morphology between the different areas of Corsican shelves, as it has been displayed on an synthetic geomorphological map. In addition, an homogeneous and overall map of surficial sediments of the Corsican shelves seabed was established and two areas, the Balagne and Agriates' platforms to the North of Corsica, and the Bonifacio Straits to the South, were mapped into details. The various...

The morpho-sedimentology of an artificial roadstead (Cherbourg, France) ArchiMer
Gregoire, G.; Méar, Y.; Poizot, E.; Marion, C.; Murat, A.; Hebert, B..
Because of its size and geographical position, the Cherbourg roadstead appears as a favourable site for Marine Renewable Energy (MRE) industry. As a result, Cherbourg harbour has undergone profound changes (2015 and 2016) due to the installation of industrial infrastructures to service the needs of expanding MRE further offshore. However, little is known about the morpho-sedimentary distribution and associated dynamics of seabed sediments before and after harbour transformations. This study focuses on sedimentary dynamics using detailed morphological and sedimentological analyses based on data acquired before changes (2012). The main map includes a unique bathymetric map (1:35,000) and sedimentary maps showing the percentage of the characteristic grain...

Active tectonics of the Calabrian subduction revealed by new multi-beam bathymetric data and high-resolution seismic profiles in the Ionian Sea (Central Mediterranean) ArchiMer
Gutscher, Marc-andre; Kopp, Heidrun; Krastel, Sebastian; Bohrmann, Gerhard; Garlan, Thierry; Zaragosi, Sebastien; Klaucke, Ingo; Wintersteller, Paul; Loubrieu, Benoit; Le Faou, Yann; San Pedro, Laurine; Dominguez, Stephane; Rovere, Marzia; De Lepinay, Bernard Mercier; Ranero, Cesar; Sallares, Valenti.
The detailed morphology and internal structure of the Calabrian accretionary wedge and adjacent Eastern Sicily margin are imaged in unprecedented detail by a combined dataset of multi-beam bathymetry and high-resolution seismic profiles. The bathymetric data represent the results of 6 recent marine geophysical surveys since 2010 as well as a compilation of earlier surveys presented as a 2 arc-sec (60 m) grid. Several distinct morpho-tectonic provinces are identified including: the deeply incised Malta–Hyblean Escarpment, numerous submarine canyons, broad regions of relatively flat seafloor dominated by fields of sediment waves, the gently undulating anticlinal fold-and-thrust belts of the external Calabrian accretionary wedge and the adjacent portion of...

Full-Waveform LiDAR Fast Analysis of a Moderately Turbid Bay in Western France ArchiMer
Launeau, Patrick; Giraud, Manuel; Robin, Marc; Baltzer, Agnes.
In shoreline monitoring, only topo-bathymetric light detection and ranging (LiDAR) can map large corridors from aerial dunes to sandbanks in shallow water. Increasing turbidity masking the formation of 532 nm laser beam echoes on the sea bed makes this challenging. Full-waveform recording all the laser beam damping functions, a turbid water column can be seen as an accumulation of layers forming a single continuum and a distinction can be made between signals ending at the bottom down to a depth of 10 m. In practice full-waveforms are converted by laser beam tracing an image cube with a grid of 1-m-wide pixels and a 0.15 m range resolution storing the mean intensities returned along incident angle. The first derivative of a wide Gaussian filter serves to...

Modeling of the bottom water flow through the Romanche Fracture Zone with a primitive equation model - Part I: Dynamics ArchiMer
Ferron, Bruno; Mercier, Herle; Treguier, Anne-marie.
This paper investigates the dynamics of the Antarctic Bottom Water (AABW) flow through the Romanche Fracture Zone (RFZ) in a primitive equation model with a high horizontal and vertical resolution. Two examples of Rows over simple bathymetries show that a reduced gravity model captures the essential dynamics of the primitive equation model. The reduced gravity model is then used as a tool to identify what are the bathymetric structures (sills, narrows) that mostly constrain the AABW flow through the RFZ. When only these structures are represented in the primitive equation model, the AABW how is shown to be coherent with observations (transports, density and velocity structures).

Circulation de bord ouest de l'Atlantique Sud: analyse d'observations lagrangiennes et hydrologiques ArchiMer
Legeais, Jean-francois.
The "World Ocean Circulation experiment" (WOCE) program in the 1990s has produced the equivalent of 300 years of subsurface floats trajectories within the Antarctic Intermediate Water (AAIW) at 800dbar in the South Atlantic ocean, and several hydrological transects. In order to compute the western boundary circulation, the flow is vertically extrapolated by referencing geostrophic hydrological profiles to float speeds. Several transects normal to the continental slope and another one parallel to it off the coast give transports of the water masses with a good transversal and longitudinal resolutions. Floats at 800dbar sampled the Intermediate Western Boundary Current (IWBC) particularly well, and enable one to analyse it from 28°S at the bifurcation of the...

Un bilan de la télédétection appliquée aux milieux coralliens ArchiMer
Andrefouet, Serge; Maritorena, Stéphane; Loubersac, Lionel.
The aim of this paper is to present in a practical fashion the status of the use of remote sensing for the study of coral reef environments through the analysis of work published in the years 1980-2000. We review the scales of the potential work and of that actually conducted, the principal applications and their limiting factors. We detail these limitations which are of a technological nature (spatial and spectral resolution of sensors), as well as often of a conceptual (role of remote sensing in the study) or methodological (image processing) nature. The understanding of these limitations, in relation to the reality of the field, allows identification of work which could be undertaken in the years 2000.

The use of multibeam backscatter and bathymetry as a means of identifying faunal assemblages in a deep-sea cold seep ArchiMer
Sen, Arunima; Ondreas, Helene; Gaillot, Arnaud; Marcon, Yann; Augustin, Jean-marie; Olu, Karine.
Deep-sea ecosystems have attracted considerable commercial interest in recent years because of their potential to sustain a diverse range of mankind's industrial needs. If these systems are to be preserved or exploited in a sustainable manner, mapping habitats and species distributions is critical. As biodiversity at cold-seeps or other deep-sea ecosystems is driven by habitat heterogeneity, imagery is the obvious choice for characterizing these systems and has indeed proven extremely valuable towards mapping biogenic habitats formed by dense aggregations of large sized species, such as coral reefs, tubeworm bushes or bivalve beds. However, the acquisition of detailed images with resolution sufficient for reliable identification is extremely time...

Dynamique sédimentaire et évolution holocène d'un système macrotidal semi-fermé : l'exemple de la rade de Brest ArchiMer
Gregoire, Gwendoline.
The bay of Brest is a tide-dominated, semi-enclosed coastal basin, which is connected with two rivers (Aulne and Elorn). Its jagged shoreline and seabed morphology constitute an ideal setting to understand sedimentary transfer at the land-sea interface. In this aim, this study is divided in two different time scale. The first (a) focuses on the present-day sedimentary bedload dynamic and the second (b) on the reconstruction of the Holocene infilling, during the last marine transgression. (a) A analyse combining a sedimentology approach and numerical has highlighted the major control of the tidal currents. Swells and rivers have a minor impact, because the inherited morphology accentuates and promotes tidal currents. There are responsible of a shelly sandy...

Atlas thématique de l'environnement marin en baie de Saint-Brieuc (Côtes-d'Armor) ArchiMer
Augris, Claude; Hamon, Dominique.
This atlas presents in a synthetic form the hydrodynamical, geological and biological characteristics of one of the most studied region of the French littoral. Geologic and geophysical data of the Saint-Brieuc Bay show that the deep basement consists of pre-palaeozoic or palaeozoic sedimentary series in the centre of the Bay, whereas metamorphic and magmatic formations are dominant in coastal regions. The location of superficial sediments in the Bay, is mainly due to marine currents. A granulometric gradient, from very fine to coarse sediments, appears in two directions: from the coast towards the high sea, and from the west to the east. Rocky substrates disrupt the sediment distribution, with, most of the time, a concentration of coarse sediments near the...
