1. Morfodinâmica associada entre duna, praia e zona submarina como subsídio a adequada ocupação do espaço costeiro na Praia do Peró - RJ. / Morphodynamics associated between dune, beach and underwater area as an aid to proper occupation of coastal space in Praia do Pero - RJ.
The coastline offers a veritable mosaic of diversity in coastal landforms, which enable the development of a number of different economic activities. Coastal environments are highly dynamic and involve a complex series of continental and oceanic processes. The beach of Pero, located between Cape Buzios and Cabo Frio, Rio coast, appears as an area distinct fr

2. A erosão costeira e sua influência sobre a atividade petrolífera: alternativas sustentáveis na mitigação de impactos ambientais
The study area consist in high sensitivity environments located on the northern coast of Rio Grande do Norte, Northeast Brazil. The barrier island are the main geomorphological features on the coastal landscape, being naturally instable and surrounded by industrial activities like oil fields, salt industry, shrimp farms and urban areas sometimes installed pa

3. Balanço de sedimentos arenosos da enseada de Balneário Camboriú-SC
O objetivo principal deste estudo é a análise do balanço de sedimentos arenosos na enseada de Balneário Camboriú, localizada no litoral centro-norte do Estado de Santa Catarina. Para alcançar os objetivos deste trabalho a enseada foi compartimentada em células e utilizadas diferentes metodologias que envolveram a análise de diversos parâmetros, tais

4. Sediment distribution model in marine shelf area : a cambrian example from the Sergipano Belt (Lagarto Formation, Estancia Domain, Sergipe) / Modelo de distribuição de sedimento em area de plataforma marinha : um exemplo do cambriano da faixa sergipana (Formação Lagarto, Dominio Estancia, Sergipe)
Coastal areas of wave-influenced tidal plains are not well known in recent and ancient depositional systems. The Lagarto Formation represents one of these mixed depositional systems influenced both by tide and wave activities. This work describes the sediments in this system, interprets the depositional processes and defines a distributional model of sedimen

5. Inter-relação paleossolos e sedimentos em lençois de areia eolica da Formação Marilia (noroeste da Bacia Bauru) / Iterrelation of palaeosols and sediment in the ancient Marilia Formation aeolian sand sheets (northwestern Bauru Basin)
The Marília Formation (Maastrichtian), outcropping in the northwestern portion of the Bauru Basin (Goiás and Mato Grosso do Sul brazilian states), is interpreted here as an ancient Aeolian sand sheet. The vertical succession, c.150 m thick, is made up of very fine to medium-grained sandstone and, it is characterised by cyclic interbedding of sediments and

6. Produção de sedimentos em áreas urbanas: o caso da Microbacia do Córrego do Pau DAlho. Guarulhos, SP
This work presents the research results about sediment yield related to actual land use in Pau dAlho watershed, about 0, 51 km2, located at Cabuçu region, Guarulhos, SP. The research was conducted by an Engineering Geology approach encompassing technogenic sediment deposits survey, the environment characterization and the history of land use that originated

7. Biodisponibilidade de mercurio e outros metais-traço em sedimentos do Rio Cubatão, Sistema Estuarino de Santos-Cubatão (SP) / Bioavailability of mercury and other trace-metals in sediments of Cubatão River, Santos-Cubatão Estuarine System (SP)
Coastal-estuarine ecosystems from the south of São Paulo State are presently degraded specially in Cubatão municipality, in consequence of population concentration and, industrial and petrochemical complexes. These environmental impacts have begun in the 1950s after the construction of the largest Latin America petrochemical complex in the Cubatão city.

8. Contribution of the acid volatile sulfide in the control of metal bioavailability in sediments of the Morrão river, estuary system of Santos-Cubatão (SP) / Contribuição dos sulfetos volatilizados por acidificação no controle da biodisponibilidade de metais em sedimentos do rio Morrão, sistema estuarino de Santos-Cubatão (SP)
Estuaries, in general, reducer environments in which anthropogenic activities could result in high metal levels in the sediments. Sulfides are important phases in the control of the concentration of some free metals in those sediments. The majority of sulfides in sediments occurs as iron bisulfides and iron monosulfide, being the last the most reactive. Due

9. Avaliação de impactos ambientais nos tributários do lago Paranoá, Brasília - DF
The high level of urbanization in Distrito Federal in Brazil is contributing to modify the environment particularly the quality of surface water resources. The historical of environment aggression to the Paranoá Lake through urban expansion, land use and land occupation, is studied as environmental changes. In this work, physical-chemistry conditions and ge

10. Distribuição de mercúrio total como indicador de poluição urbana e industrial na costa brasileira
The monitoring of the pollution status of the Brazilian coast is hampered by the lack of a consistent environmental indicator. We propose Hg as an environmental proxy to anthropogenic pollution of coastal regions due to its absence in the Brazilian geology, its ubiquity in anthropogenic effluents, and its toxicity. Available data suggest Hg "backgrounds" in

11. SIMULATION OF TRANSPORT AND DEPOSITION OF SILICICLASTIC SEDIMENTS IN PLATAFORM, SLOPE, AND BASIN ENVIRONMENTS / SIMULAÇÃO DE TRANSPORTE E DEPOSIÇÃO DE SEDIMENTOS SILICICLÁSTICOS EM AMBIENTES DE PLATAFORMA, TALUDE E BACIA
Sedimentary Geology deals with the study of the physical, chemical and biological processes operating in the surface of the Earth, not only in the present days, but also along all History. Therefore, it can be applied in miscellaneous fields, as, for example, in the study of fossils fuels formation. One of the main focus of sedimentary geology inhabits in de
