1. Euphausiacea diversity in a trans-oceanic transect through the South Atlantic Ocean: the first Atlantic record of Thysanopoda astylata Brinton, 1975
Abstract: Information about euphausiids in central South Atlantic Ocean is scarce; hence, we investigated species composition and distribution of euphausiids along a longitudinal transect in this region, with an emphasis on Thysanopoda. Zooplankton samples were collected from 44 stations during the first Transatlantic Commission (Brazil–Africa). Euphausiid

2. Development and characterization of 20 polymorphic microsatellite markers for Epinephelus marginatus (Lowe, 1834) (Perciformes: Epinephelidae) using 454 pyrosequencing
Abstract The dusky grouper, Epinephelus marginatus, is a well-known and widespread marine fish assessed as endangered by the International Union for the Conservation of Nature. Analyzing the genetic diversity of this species is, therefore, of utmost importance and necessary for conservation purposes. Microsatellites are molecular tools with advantages that a

3. The Effectiveness of Thin-Walled Hull Structures Against Collision Impact
Abstract The impact phenomenon is one of many subjects that is interesting and has become an inseparable part of naval architecture and ocean engineering fields. Limitless possibilities in cause and scenario make the demand to understand the physical behavior of ship structures due to impact phenomenon is increasing. In present work, a series of virtual expe

4. Survey and study of graphite occurrences in the Aracoiába-Baturité graphite bearing District, CE / Levantamento e estudo das ocorrências de grafita do Distrito Grafitífero Aracoiába-Baturité, CE
The Aracoiába-Baturité Graphite-bearing District has graphitic gneiss deposits (disseminated ore) and vein (solid ore) with different genetic origins and their own physical characteristics and geological environments. The graphite gneiss ore is of sedimentary, syngenetic origin, with 1.5% to 8% C content, which is distributed along two long parallel belts,

5. Estrutura e evolução dos cordões arenosos pleistocênicos no canal de acesso à Laguna dos Patos-RS, Brasil
This work presents the results of a high-resolution seismic reflection data survey carried out in the Patos lagoon inlet, near Rio Grande the southernmost harbor of Brazil. The analysis of the reflection patterns reveals the presence of transgressive/regressive barrier structures and beach/foredune-ridges. The mapping of these barrier structures allows a bet

6. Response of vertical pile group subjected to horizontal cyclic load in soft clay
The environment prevalent in ocean necessitates the piles supporting offshore structures to be designed against lateral cyclic loading initiated by wave action. Such quasi-static load reversal induces deterioration in the strength and stiffness of the soil-pile system introducing progressive reduction in the bearing capacity as well as the pile head displace

7. Variabilidade da infauna adjacente a estruturas rochosas na plataforma rasa do litoral do Paraná, Brasil
Ocean rocky formations are known as islands. When islands become completely submerged, they are called stone slabs. Like reefs, these formations alter the flux of water produced by the waves, which in turn interacts with the adjacent sediment, altering the sediment and its undulation marks. The alterations caused by the interaction between the waves and emer

8. Contributions to the understanding and planning of urban occupation of Baixada de Jacarepagua - Rio de Janeiro / RJ: an application of matrix S.P.I.R. / Contribuições para o entendimento e planejamento da ocupação urbana da Baixada de Jacarepaguá - Rio de Janeiro / RJ: uma aplicação da matriz P.E.I.R
This dissertation presents a geographical approach, applying the methodology Matrix PEIR, in Baixada Jacarepaguá. The Brazilian coast, the colonial period to the present day, has suffered a progressive human occupation that gradually degrades and distorting the natural coastal environments, rather than new forms of urban environment. The marshland is an Jac

9. Barotropic instability process of Brazil current at Santos Basin / Processos de instabilidade barotrópica da Corrente do Brasil na Bacia de Santos
The Brazil Current (BC) is formed at the bifurcation of the southern branch of the South Equatorial Current and flows south-southeastward off the east, southeast and southern Brazilian continental margin, exhibiting intense meso-scale activity between the Vitória-Trindade Ridge (20oS) and Cape Santa Marta Grande (28oS). The knowledge of such activity, built

10. Estudo filogeográfico de duas espécies de medusozoários (Cnidaria), Liriope tetraphylla (Trachymedusae, Gerioniidae) e Olindias sambaquiensis (Limnomedusae, Olindiasidae), em uma região do Oceano Atlântico Sul-Ocidental / Phylogeographic study of two medusozoan species (Cnidaria), Liriope tetraphylla (Trachymedusae, Geryoniidae) and Olindias sambaquiensis (Limnomedusae, Olindiasidae), in a region of the South Western Atlantic Ocean
Medusozoan species, with quite different life-cycles, inhabit different seas and oceans around the world. In a regional scale, some hydrozoan species are widespread along the Southwestern Atlantic Ocean (Brazilian and Argentinean shores), with populations distributed along a heterogeneous and structured environment. The relation between the distribution of t

11. Análise dos critérios de estabilidade para projetos de plataformas do tipo monocoluna. / Analysis of the stability criteria of monocolumn type platform design.
To be classified and approved by a classification society, all offshore structures shall be submitted and analyzed according to standard rules. The stability criteria are based on the IMO MODU (International Maritime Organization Mobile Offshore Drilling Units) Code which has reference to almost all types of floating units such as surface, column-stabilized

12. Electricity generation from the offshore wind energy source. / Geração de energia elétrica a partir da fonte eólica offshore.
In the last decade wind power source was the fastest-growing energy source. Technological learning curves for this sector fall down by a 15% a 20% rate each 3 years. Countries which are committed with wind power are running after the target of 12% wind into the worlds electrical production by 2020. The contribution of the offshore wind power (OWP) source is
